Nikolas Georgesku-Rogen (tug'ilgan Nikolae Georgesku, 1906 yil 4 fevral - 1994 yil 30 oktyabr) a Rumin matematik, statistik va iqtisodchi. U bugungi kunda 1971 yil bilan tanilgan magnum opus Entropiya qonuni va iqtisodiy jarayon, bu erda u hamma narsani ta'kidladi Tabiiy boyliklar iqtisodiy faoliyatda foydalanishga topshirilganda qaytarib bo'lmaydigan darajada tanazzulga uchraydi. A avlod va a paradigma asoschisi yilda iqtisodiyot, Georgescu-Roegenning yaratilishida asosiy ish bo'ldi ekologik iqtisodiyot iqtisodiyotning mustaqil akademik sub-intizomi sifatida.

Bir necha iqtisodchilar Jorjesku-Rogenni o'z davridan ancha oldin yashagan odam sifatida maqtashgan va ba'zi iqtisodiy fikr tarixchilari uning ishining zukkoligini e'lon qilishgan.^{[7]:79[8]:1[9]:102} Bunday minnatdorchilikka qaramay, Georgesku-Roegen hech qachon mukofotlanmagan Iqtisodiyot bo'yicha Nobel mukofoti, garchi uning vatani Ruminiyadan xayr-ehson qiluvchilar uning nomidan lobbi qilishgan.^[10]:270f Georgesku-Rojen vafotidan so'ng, uning ishini omon qolgan eng yuqori darajadagi do'sti maqtadi: Mashhur Keynsiyalik iqtisodchi va Nobel mukofoti laureati Pol Samuelson Jorjesku-Rogen o'z hayotida shon-shuhratni to'liq anglamagan taqdirda, uning o'rniga avlodlar berganidan xursand bo'lishini aytdi.^[11]:xvii

In iqtisodiy fikr tarixi, Georgescu-Roeg butun dunyodagi degan nazariyani ilgari surgan ba'zi iqtisodchilarning birinchi iqtisodchisi edi. mineral resurslar oxir-oqibat bir muncha vaqt charchagan bo'ladi.^{[5]:13[12]:164f[8]:160–171} Yilda uning paradigmatik magnum opusi, Georgescu-Roegen iqtisodiy tanqislik jismoniy haqiqat bilan asoslanadi; barchasi shu Tabiiy boyliklar iqtisodiy faoliyatda foydalanishga topshirilganda qaytarib bo'lmaydigan darajada tanazzulga uchragan; bu tashish hajmi kelajakda erning cheklangan mineral zaxiralari qazib olinib, foydalanishga topshirilayotganda, ya'ni erning odamlarning populyatsiyasi va iste'mol darajasini saqlab turish qobiliyati - bir muncha vaqt kamayishi shart; va shuning uchun jahon iqtisodiyoti Umuman olganda, kelajakda muqarrar ravishda qulashga intilib, oxir-oqibat odamlarning yo'q bo'lib ketishi.^[13] Tufayli radikal pessimizm ning jismoniy tushunchasiga asoslanib, uning ishiga xosdir entropiya, Georgesku-Rojen va uning izdoshlarining nazariy pozitsiyasi keyinchalik nomlandi "entropiya pessimizmi".^[14]:116

Hayotining boshlarida Georgesku-Rogen talaba va homiysi bo'lgan Jozef Shumpeter, kim qaytarib bo'lmaydigan evolyutsion o'zgarish va "ijodiy halokat" uchun xosdir kapitalizm.^[4]:138f Keyinchalik Georgesku-Roegen o'qituvchi va murabbiy edi Xerman Deyli, keyin a tushunchasini ishlab chiqishga kirishgan barqaror iqtisodiyot (dunyo) iqtisodiyoti orqali tabiiy resurslar oqimiga doimiy hukumat tomonidan cheklovlar qo'yish.^[15]

U tabiiy resurslar oqimlarini iqtisodiy modellashtirish va tahlilga olib borganligi sababli, Georgesku-Rogenning faoliyati asos yaratishda muhim ahamiyatga ega edi ekologik iqtisodiyot mustaqil akademik sub-intizom sifatida iqtisodiyot 1980-yillarda.^{[16]:150f[17]:65–68[18]:422[19]:302f} Bundan tashqari, o'sish harakati 2000-yillarning boshlarida Frantsiya va Italiyada tashkil topgan Georgescu-Roegenni tan oladi harakatga ta'sir qiluvchi asosiy intellektual shaxs.^{[20]:1742[21]:xi[22]:1f} Birgalikda, 2010 yillarga kelib, Georgesku-Roegen butun dunyo bo'ylab odamlarning kamida uch avlodini, shu jumladan uning zamonaviy tengdoshlarini, yosh ekologik iqtisodchilarni, yoshini pasaytiruvchi tashkilotchilari va faollarini va boshqalarni o'z ichiga olgan holda o'qitdi, ta'sir qildi va ilhomlantirdi.

Ko'pchilikning qobiliyatsizligi yoki istamasligi asosiy iqtisodchilar Jorjesku-Rojenning ishini tan olish uning ko'pgina asarlari o'qilishi bilan bog'liq amaliy fizika iqtisodiyotdan ko'ra, chunki bu oxirgi mavzu bugun o'qitiladi va tushuniladi.^{[23]:71[24]:112[25]:106–109}

Jorjesku-Rogenning ishi, uning fizika fanini yetarlicha tushunmasligi tufayli yuzaga kelgan xatolar tufayli biroz kamchiliklarga uchradi. termodinamika. Ushbu xatolar keyinchalik ikkalasini ham o'z ichiga olgan ba'zi tortishuvlarga sabab bo'ldi fiziklar va ekologik iqtisodchilar.^{[26]:21–28[27][28]:56f[29]:1215–1218}

Hayot va martaba

Nikolas Georgesku-Rogen (tug'ilgan Nikolae Georgesku) ning hayoti 20-asrning aksariyat qismini, 1906 yildan 1994 yilgacha davom etdi. Uning tug'ilgan joyida Ruminiya, u mamlakatdan qochishidan oldin ikki jahon urushi va uchta diktaturani boshdan kechirdi. Umrining ikkinchi yarmida AQShda siyosiy muhojirlikda yashab, u uzoqdan Ruminiyada sotsializmning ko'tarilishi va qulashiga guvoh bo'ldi. U asosiy oqimga ko'plab muhim hissa qo'shdi neoklassik iqtisodiyot nihoyat u bunga qarshi chiqdi va nashr qildi paradigmatik magnum opus yoqilgan Entropiya qonuni va iqtisodiy jarayon. Garchi bu ish tashkil etishda seminal bo'lgan bo'lsa-da ekologik iqtisodiyot mustaqil akademik sub-intizom sifatida iqtisodiyot, Georgescu-Roegen o'zining paradigmatik ishi uchun umrida kutgan qadrini olmaganidan hafsalasi pir va achchiq vafot etdi.

Bolalik, o'spirinlik va ta'lim

Nikolae Georgesku yilda tug'ilgan Konstansa, Ruminiya 1906 yilda oddiy kelib chiqishi oilasiga. Yunon millatiga mansub otasi armiya ofitseri bo'lgan. Uning onasi, etnik rumiyalik, qizlar maktabida tikuvchilik o'qituvchisi bo'lgan. Ota o'g'lini o'qish, yozish va hisoblashni o'rgatishga vaqt ajratdi va bolaga intellektual qiziqish urug'ini ekdi. Ona o'zining tirik namunasi bilan o'g'liga mehnatning qadrini o'rgatdi. Intizomiy sabablarga ko'ra armiyadagi mavqeidan mahrum bo'lganidan so'ng, otasi Nikolae sakkiz yoshida vafot etdi.^{[13]:xiv[1][30]:1–3}

Konstanta shahri 1909 yilda

O'shanda Konstansa kichkina edi Qora dengiz taxminan 25000 aholisi bo'lgan port. Shaharda turli madaniyatlar va etnik guruhlarning aralashuvi Nikolayning dastlabki yillaridanoq kosmopolit ruhini shakllantirgan. Boshlang'ich maktabda Nikolae juda yaxshi edi matematika, va u o'qituvchi tomonidan o'rta maktabda tahsil olish uchun ariza berishga da'vat etilgan, Mânăstirea Dealu litseyi ("Litsey Tog'dagi monastir "), shaharchadagi yangi harbiy tayyorgarlik maktabi. Nikolae 1916 yilda u erda stipendiya qo'lga kiritdi, ammo uning qatnashishi kechiktirildi Ruminiyaning Birinchi Jahon urushiga kirishi. Uning beva onasi oilasi bilan qochib ketdi Buxarest, mamlakat poytaxti, bu erda ular urushning qolgan davrida Nikolaening onasi buvisida qolishgan. Ushbu qiyin paytlarda Nikolae urush azoblarini boshidan kechirgan bolalik davrlarini boshdan kechirdi. U matematika o'qituvchisi bo'lishni xohlardi, lekin u maktabdagi ishlarini zo'rg'a davom ettirar edi.^{[24]:9–11[31]:16–20[21]:1–3}

Urushdan keyin Nikolae litseyda o'qish uchun o'z uyiga qaytib keldi. O'qitish standartlari yuqori edi, keyinchalik ko'plab o'qituvchilar universitet professor-o'qituvchilariga aylandilar, ammo intizom tartibda edi, soxta harbiy jismoniy mashqlar va forma kiyib. Talabalarga yozdan tashqari va qisqa vaqt ichida Rojdestvo va Pasxa bayramlari paytida maktabdan chiqishga ruxsat berilmagan. Nikolae, ayniqsa matematikada a'lochi talaba ekanligini isbotladi. Keyinchalik u litseyda olgan besh yillik o'rta ta'limini, keyinchalik unga kariyerasida yaxshi xizmat qiladigan g'ayrioddiy ma'lumot berganligi uchun bergan, ammo u shuningdek, intizomni va joyning monastir izolyatsiyasini ijtimoiy qobiliyatlarini to'xtatganlikda ayblagan. , uni butun hayoti davomida tanishlari va hamkasblari bilan ziddiyatga olib keladigan narsa.

Litseyda Nikolae Georgeskuning ism-sharifi borligi aniqlandi. Chalkashliklarga yo'l qo'ymaslik uchun u o'z familiyasining birinchi va oxirgi harflaridan, shuningdek familiyasining dastlabki to'rt harfidan iborat bo'lgan barcha oltita harflarni teskari tartibda qo'shib, o'z familiyasiga qo'shimcha yaratishga qaror qildi. : NikolaE GEORgesku → '-Rojen'. Georgescu-Roegen ushbu qo'shimchani butun umri davomida saqlab qoladi. Keyinchalik hayotida u o'zining ismini frantsuzcha va inglizcha shakli "Nikolay" ga o'zgartirdi.

Buxarest universiteti v. 1921 yil

Georgescu-Roegen 1923 yilda litseydan diplom oldi. Kambag'al oilalar farzandlariga berilgan stipendiya tufayli u tez orada qabulga qabul qilindi. Buxarest universiteti matematikadan keyingi o'rganish uchun. U erda o'quv dasturi odatiy bo'lib, o'qitish metodikasi litseyda mavjud bo'lganlarga o'xshardi. Universitetda u keyinchalik butun hayoti davomida uning rafiqasi bo'ladigan ayol bilan uchrashdi Otiliya Busuioc. O'qish paytida o'zini ta'minlash uchun u shaxsiy darslar berdi va shahar tashqarisidagi gimnaziyada dars berdi. Uni tugatgandan so'ng jum laude 1926 yilda u o'rta maktab o'qituvchisi malakasini olish uchun imtihondan o'tdi va keyin Konstantadagi sobiq litseyida yana bir yil o'qituvchilik lavozimiga qabul qilindi.

Universitetda Georgescu-Roegen o'zining professorlaridan biri bilan yaqindan tanishdi, Traian Lalescu, hozirgi zamonning taniqli matematikasi, matematik usullardan foydalanib iqtisodiy haqiqatga tatbiq etishga alohida qiziqish bildirgan statistika. Lalesku Ruminiya iqtisodiyotini tahlil qilish uchun zarur bo'lgan ma'lumotlarning etishmasligidan xavotirda edi, shuning uchun u Georgescu-Roegenni ushbu tadqiqot yo'nalishini chet elda keyingi tadqiqotlarda davom ettirishga undadi. Tez orada Georgescu-Roegen ushbu maslahatga amal qildi: 1927 yilda u Frantsiyaga o'qish uchun ketdi Statistika instituti, Sorbonna Parijda.

Parij va Londonda o'qish

Jorjesku-Rojenning Parijda bo'lganligi sof matematikadan tashqari uning bilim doirasini kengaytirdi. U nafaqat Frantsiyadagi eng yaxshi statistika va iqtisod professorlarining ma'ruzalarida qatnashdi, balki u bilan ham shug'ullandi fan falsafasi, ayniqsa asarlari Blez Paskal, Ernst Mach va Anri Bergson. Kambag'al chet ellik talaba uchun katta shaharda kundalik hayot oson kechmadi. Ruminiyadan olgan arzimagan mablag ', hatto eng zarur ehtiyojlarini ham qondira olardi va frantsuz talabalari odatdagidek barcha chet ellik talabalarni kamsituvchi atamalar bilan atashardi. métèques, "begonalar". Ammo uning tadqiqotlari ajoyib tarzda rivojlandi: 1930 yilda Georgesku-Rogen fenomenning tsiklik tarkibiy qismlarini kashf etish bo'yicha doktorlik dissertatsiyasini himoya qildi. U g'ayrioddiy sharaf bilan o'tdi. Emil Borel, Georgescu-Roegening professorlaridan biri dissertatsiyani shu qadar yuqori darajada o'ylar ediki, uni frantsuz akademik jurnalining maxsus soni sifatida to'liq nashr ettirdi.^{[24]:11f[32]:129f[21]:3–5[31]:20–23}

Parijda o'qiyotganda Jorjesku-Rogen ishi to'g'risida bilib oldi Karl Pirson da Universitet kolleji Londonda. Pirson o'sha davrning etakchi ingliz olimi bo'lib, qiziqish doirasi Jorjesku-Rogenning o'ziga xos bo'lgan matematikasi, statistikasi va fan falsafasiga to'g'ri keladi. Jorjesku-Rojen Parijda uchrashgan va 1931 yilda Angliyaga jo'nab ketgan yosh inglizning oilasi bilan yashashni rejalashtirgan. Londonda bo'lganida uning mezbonlari nafaqat Georgesku-Roegeni pullik mehmon sifatida qabul qilishdi, balki unga mamlakatda o'qish uchun tayyorgarlik paytida ingliz tili asoslari.

Pirsonning qiziqish doirasi Jorjesku-Rojennikiga to'g'ri keldi.

U Pirsonga va ingliz universitetlari tizimiga murojaat qilganida, Georgesku-Roegen topgan norasmiyligi va ochiqligidan hayratga tushdi. A kabi boshqa tuyg'u yo'q edi métèque, begona. Keyingi ikki yil davomida Pirson bilan birga o'qish va Pirsonning fan falsafasi bo'yicha asarini o'qish Ilmiy grammatika, Georgescu-Roegenning ilmiy metodologiyasi va falsafasini yanada shakllantirdi. Ikkalasi do'stlashdi va Pirson Georgesku-Rogenni matematik statistika bo'yicha o'qishni davom ettirishga undadi. Ular "muammo" deb nomlangan tadqiqotlar bo'yicha kashshof bo'lishdi lahzalar ", o'sha paytdagi statistikaning eng qiyin mavzularidan biri bo'lgan, ammo ikkalasi ham bu muammoni hal qila olmagan. Bu Pirson uchun juda katta umidsizlik edi, ammo Jorjesku-Rojen ularning birgalikdagi sa'y-harakatlaridan mamnun edi.

Londonda o'qiyotganda, Jorjesku-Rojen bilan AQShda joylashgan vakili murojaat qildi Rokfeller jamg'armasi. O'tmishdagi akademik yutuqlari tufayli fond Georgescu-Roegenga AQShda ilmiy izlanishlar olib borishni xohlamoqda. Georgescu-Roeg o'sha paytdagi mashhur Garvard Iqtisodiy Barometri tomonidan vaqt seriyali tahlillaridan foydalanish to'g'risida oldinroq bilib olgan edi. Garvard universiteti, shuning uchun u grantni qabul qildi. Safar taxminan bir yilga qoldirildi, ammo u Ruminiyada ko'proq majburiyatlarga ega edi: u o'zining birinchi milliy tahririyat loyihasini, 500 betlik qo'llanmani yakunlashi kerak edi. Metoda StatistikaăVa u sog'lig'i yomon bo'lgan keksa beva onasiga g'amxo'rlik qilishi kerak edi.

AQShga sayohat, Shumpeter bilan uchrashish

1934 yilning kuzida Jorjesku-Rogen AQShga bordi. Etib kelganida Garvard universiteti, u Iqtisodiy Barometr bir necha yil oldin yopilganligini bilib oldi: Loyiha butunlay bashorat qila olmadi 1929 yildagi Wall Street halokati, va tez orada butunlay tark etildi. O'z tadqiqotlari uchun boshqa homiy izlashga urinishlardan bir nechta muvaffaqiyatsiz urinishlardan so'ng, Jorjesku-Rojen nihoyat universitet o'qituvchisi bilan uchrashuvni o'tkazdi. biznes tsikllari unga boshqa imkoniyatlar mavjudligini ko'rish uchun. Ushbu professor sodir bo'ldi Jozef Shumpeter.^{[24]:11–13[30]:3–5[31]:22–24[21]:5–8}

Shumpeter Garvardda Georgesku-Rogenning ustoziga aylandi.

Shu payt Shumpeter bilan uchrashish Georgesku-Rogenning hayoti va karerasini butunlay o'zgartirdi. Shumpeter Georgesku-Rojenni Garvardda iliq kutib oldi va tez orada uni shu muassasada ishlagan iqtisodchilarning eng ajoyib guruhlaridan biri bo'lgan hozirgi mashhur "davraga" kiritdi, shu jumladan. Vasili Leontiv, Oskar Lange, Fritz Machlup va Nikolas Kaldor, Boshqalar orasida. Jorjesku-Rojen endi haftalik oqshom yig'ilishlari va norasmiy akademik munozaralar bilan intellektual muhitda edi, u erda Shumpeter o'zi davraning "ringmasteri" sifatida boshqargan. Shumpeterda Georgesku-Rogen vakolatli va hamdard murabbiyni topdi. Garchi Georgesku-Rojen hech qachon biron bir iqtisodiy darslarga rasmiy ravishda ro'yxatdan o'tmagan bo'lsa-da, u shunday qilib iqtisodchi bo'ldi: "Shumpeter meni iqtisodchiga aylantirdi ... Mening iqtisod bo'yicha yagona ilmiy darajam shu Universitas Shumpeteriana."^[32]:130

Garvardda bo'lganida, Georgescu-Roegen o'zining keyingi iste'mol va ishlab chiqarish nazariyalariga asos solgan to'rtta muhim hujjatni nashr etdi.^{[33][34][35][36]} Ushbu maqolalarning ilmiy sifati Shumpeterni hayratga soldi.

Jorjesku-Rogenning AQShga safari Garvardda o'tmagan. U o'zi va rafiqasi Otiliya uchun Kaliforniyaga qadar sayohat qilib, mamlakat bo'ylab sayohat qilish imkoniyatini beradigan kamtarona stipendiya olishga muvaffaq bo'ldi. Shumpeterning aloqalari orqali Georgesku-Roegen uchrashish imkoniyatiga ega bo'ldi Irving Fisher, Garold Hotelling va kunning boshqa etakchi iqtisodchilari. U ham uchrashdi Albert Eynshteyn da Princeton universiteti.

Uning davrida Georgesku-Rojenning Shumpeter bilan munosabatlari rivojlandi. Georgesku-Rojening istiqbolli yosh olim ekanligini anglagan Shumpeter uni Garvardda saqlamoqchi edi. U Georgescu-Roegenga iqtisod fakulteti bilan ishlashni taklif qildi va u bilan hamkorlikda iqtisodiy risola ustida ishlashni iltimos qildi, faqat ikkalasi, lekin Georgescu-Roegen rad etdi. U shu paytgacha ta'limining ko'p qismini homiylik qilgan orqada qolgan vataniga xizmat qilish uchun Ruminiyaga qaytmoqchi edi; Bundan tashqari, uning qaytishi uyda kutilgan edi. Keyinchalik Jorjesku-Rojen o'z karerasining shu davrida Shumpeterning saxiy taklifidan bosh tortganiga afsuslanar edi.^{[32]:132[21]:7f}

1936 yil bahorida Georgesku-Rogen AQShni tark etdi. Uning Ruminiyaga qaytishi deyarli uzoq davom etgani uchun o'z-o'zidan deyarli bir yil davom etdi Fridrix Xayek va Jon Xiks da London iqtisodiyot maktabi uyga ketayotganda. U qaytishga shoshilmadi.

Ruminiyalik "surgun" va u erdan parvoz

1937 yildan 1948 yilgacha Jorjesku-Rogen Ruminiyada yashagan va u erda hamma narsaning guvohi bo'lgan Ikkinchi Jahon Urushining notinchliklari va haddan tashqari haddan ziyodlari va keyingi kommunistlarning hokimiyat tepasiga ko'tarilishi mamlakatda. Urush paytida, Georgescu-Roegen sil kasalligiga qarshi emlashga o'lim reaktsiyasi tufayli yagona akasini yo'qotdi.^{[24]:13f[30]:5–7[21]:8–10}

Jorjesku-Rogen AQShdan Buxarestga qaytgach, tez orada bir qancha hukumat lavozimlariga tayinlandi. Uning doktorlik dissertatsiyasi Sorbonna Uning boshqa ilmiy ma'lumotlari ham hamma joyda obro'li obro'ga ega bo'ldi va uning fransuz va ingliz tillarini yaxshi bilishi tashqi aloqalar bo'limida zarur edi. U har kuni mamlakat tashqi savdosi to'g'risidagi ma'lumotlarni yig'ish uchun mas'ul bo'lgan Markaziy statistika instituti direktorining o'rinbosari bo'ldi; u shuningdek, yirik xorijiy davlatlar bilan tijorat shartnomalarini tuzgan holda Milliy savdo kengashida ishlagan; hatto u bilan bog'liq diplomatik muzokaralarda qatnashgan Ruminiyaning Vengriya bilan milliy chegaralarini qayta belgilash.

Georgesku-Rogen siyosat bilan shug'ullangan va monarxiyani qo'llab-quvvatlagan Milliy dehqonlar partiyasi. Mamlakat iqtisodiyoti hali rivojlanmagan va yirik agrar bazaga ega edi, bu erda dehqonlar ommasi qoloqlik va qashshoqlikda yashagan. Aholining qishloq va shahar qismlari o'rtasidagi eng dahshatli tengsizliklar yumshatilishi kerak bo'lsa, erni sezilarli darajada isloh qilish kerak edi. Georgescu-Roeg bu ishda ishontiruvchi harakatlarni amalga oshirdi va tez orada partiyaning Milliy Kengashiga a'zo bo'lib, partiyaning yuqori darajalariga ko'tarildi.

Jorjesku-Rogen hayotining ushbu davrida ozgina ilmiy ish bilan shug'ullangan. Milliy ensiklopediyani birgalikda tahrirlashdan tashqari Romaniey ensiklopediyasiva ba'zi bir kichik statistik nashrlarda mamlakatning iqtisodiy ahvoli to'g'risida xabar berib, u ilmiy ahamiyatga ega hech narsa nashr etmadi. Garchi u o'z vatanida yashagan bo'lsa-da, keyinchalik Jorjesku-Rogen hayotining ushbu davrini Ruminiyalik "surgun" deb ataydi: surgun uning uchun intellektual davr edi.

Urushning aksariyat davrida Ruminiya fashistik Germaniya bilan ittifoqdosh bo'lgan "eksa kuchi" bo'lgan Bolshevizm."

Urushning oxiriga kelib, Ruminiya Sovet Ittifoqi tomonidan bosib olingan. Ishonchli hukumat amaldori va nufuzli siyosiy partiyaning etakchi a'zosi Jorjesku-Rojen muzokaralar uchun mas'ul bo'lgan qurollanish komissiyasining bosh kotibi etib tayinlandi. bosib oluvchi davlat bilan tinchlik uchun sharoitlar. Muzokaralar yarim yilga cho'zilib ketdi va uzoq va og'ir bahslarni o'z ichiga oldi: Urushning aksariyat davrida, Ruminiya eksa kuchi bo'lgan bilan ittifoqdosh Natsistlar Germaniyasi Shunday qilib, sovet vakillari komissiyani Ruminiya xalqiga mumkin bo'lgan eng katta miqdordagi urush kompensatsiyasini undirish vositasi sifatida qarashgan.

Kommunistlar hokimiyat tepasiga ko'tarilgach, Milliy dehqonlar partiyasining etakchi a'zolari to'planib, kiyib olindi sud jarayoni 1947 yilda. Ko'pchilik umrbod qamoq jazosiga hukm qilindi.

Urushdan keyin mamlakatda siyosiy kuchlar Georgesku-Rogenga tajovuz qilishni boshladilar. Urushgacha va urush paytida Ruminiyada allaqachon bo'lgan ketma-ket uchta diktaturadan o'tdi va to'rtinchisi yaqinda edi. Jorjesku-Rojenning tarixidagi ko'plab narsalar mahalliy Ruminiya kommunistlari va mamlakatni hanuzgacha egallab turgan sovet hokimiyatiga qarshi turish uchun mos edi: uning Kommunistlar partiyasiga ochiq qarshilik ko'rsatgan Dehqonlar partiyasining eng yuqori a'zosi; uning qurolli qurollar komissiyasida muzokaralar olib boradigan bosh vaziri, Ruminiyaning suverenitetini bosib oluvchi davlatga qarshi himoya qilgan; va ilgari uning Garvard universitetida Rokfeller tadqiqotchisi sifatida kapitalistik AQSh bilan aloqasi. Mamlakatda siyosiy repressiyalar kuchaygan kommunistlarning hokimiyat tepasiga ko'tarilishi nihoyasiga etkazayotgan edi va Jorjesku-Rojen nihoyat qochish vaqti kelganligini angladi: "... men hech qachon tirik chiqmagan qamoqxonaga tashlanishimdan oldin Ruminiyadan qochishim kerak edi."^[32]:133 Yahudiy jamoasining yordami bilan - u ilgari yahudiylarga yordam berish orqali bo'ynini xavf ostiga qo'ygan edi Xolokostning Ruminiya qismi - Georgesku-Rojen va uning rafiqasi soxta shaxsiy guvohnomalarni qo'lga kiritishdi, bu esa ularni mamlakatdan olib chiqib ketishni ta'minladi, pora bilan kontrabandachilar qurshovida qoldi va Turkiyaga ketayotgan yuk tashiydigan idishda saqlanib qoldi.

Bundan oldin Turkiyaga rasmiy ish bilan tashrif buyurgan Georgescu-Roegen u erdagi aloqalaridan foydalanib, AQShning Garvard universitetidagi Shumpeter va Leontiefga o'z parvozi to'g'risida xabar bergan. Leontiev Georgesku-Rojenga Garvardda ishlashni taklif qildi va er-xotin u erga kelishidan oldin kerakli tadbirlarni amalga oshirdi.

Qo'shma Shtatlarda yashash, Vanderbilt universitetida yillar

Turkiyadan Evropa qit'asi bo'ylab sayohat qilgandan so'ng, Georgesku-Rogen va uning rafiqasi etib kelishdi Cherbourg Frantsiyada, ular kemadan Atlantika okeanini kesib o'tdilar. 1948 yil yozida Jorjesku-Rojenning Garvardga kelishi uning uchun u erda qaytish bo'ldi. Hozirgina, sharoitlar 1930-yillardagidan ancha farq qilardi: U endi chet el safarida, o'z ona mamlakati tomonidan qo'llab-quvvatlanadigan va homiylik qilgan umidli yosh olim emas edi; o'rniga, u orqasida kommunistik diktaturadan qochgan o'rta yoshli siyosiy qochqin edi Temir parda. Shunga qaramay, u Garvardda xuddi shunday kutib olindi va u bilan hamkorlik qilib, ma'ruzachi va tadqiqotchi sifatida ish topdi Vasili Leontiv Garvard iqtisodiy tadqiqotlar loyihasi va boshqa mavzular bo'yicha. Ammo bu doimiy ish emas edi.^{[24]:14–18[31]:24–27}

Garvardda ishlayotganda, Georgesku-Roegenga murojaat qilishdi Vanderbilt universiteti unga iqtisod professori sifatida doimiy ilmiy kafedrani taklif qildi. Georgescu-Roegen taklifni qabul qildi va Vanderbiltga ko'chib o'tdi Nashvill, Tennesi 1949 yilda. Jorjesku-Rojenning Garvarddan unchalik obro'li bo'lmagan Vanderbiltning doimiyligi va barqarorligiga o'tishga qaror qilishiga uning urush davridagi bexatar tajribalari va yangi mamlakatda siyosiy qochqin sifatida ishonchsizlik hissi sabab bo'lganligi ta'kidlandi.^[24]:14f Bundan tashqari, bu da'vo qilingan Jozef Shumpeter Garvardda doimiy mavqega ega bo'lishiga imkon beradigan (Shumpeter 1950 yilda vafot etgan) o'zining oldingi ta'sirini yo'qotgan edi.^[21]:11 Jorjesku-Rigen 1976 yilda 70 yoshida nafaqaga chiqqaniga qadar Vanderbiltda qoldi. Qisqa safarlar bundan mustasno, u endi Nashvillni tark etmas edi.

Vanderbilt universiteti

Vanderbilt universitetida ishlagan yillari davomida Georgesku-Rogen ajoyib ilmiy martaba bilan shug'ullangan. U qit'alarda ko'plab tashrif buyurgan uchrashuvlar va ilmiy tadqiqotlarni o'tkazdi va bir qator akademik jurnallarning muharriri bo'lib xizmat qildi, shu jumladan Ekonometrika. U 1967 yilda ish beruvchi Vanderbilt universiteti tomonidan taqdim etilgan taniqli Harvi Branskomb mukofotini ham o'z ichiga olgan bir qancha ilmiy mukofotlarga sazovor bo'ldi. 1971 yilda, xuddi shu yili uning magnum opusi nashr etildi, u sharaflandi Amerika Iqtisodiy Assotsiatsiyasining muhtaram a'zosi.^[24]:16

1960-yillarning boshlarida Jorjesku-Rojen edi Xerman Deyli talaba sifatida.^[19]:305 Keyinchalik Deyli etakchi ekolog iqtisodchiga aylandi, shuningdek iqtisodchilar kasbining eng sodiq, doimiy va ta'sirchan tarafdori Jorjesku-Rogen iqtisodiyotining targ'ibotchisiga aylandi.^{[15]:7–12[16][37][38]:61–76[39][40]:545f} Biroq, Georgesku-Rogen, o'z navbatida, keyinchalik shogirdining ishiga tanqidiy munosabatda bo'ladi (pastga qarang ).

Ning nashr etilishi Jorjesku-Rogenning magnum opusi 1971 yilda hech qanday zudlik bilan munozaralarga sabab bo'lmadi iqtisodiy kasbning asosiy oqimi va etakchi asosiy jurnaldagi yagona sharh o'quvchilarni muallif tomonidan qilingan "noto'g'ri bayonotlar va falsafiy umumlashmalar" dan ogohlantirdi; ammo Georgescu-Roeg evolyutsion iqtisodchilar tomonidan heterodoks tomonidan to'rtta ijobiy baholarni oldi.^[41]:2274

Yaylovlar direktori edi Rim klubi loyiha MIT 1970-72 yillarda.

1970-yillar orqali Georgesku-Roegen bilan qisqa muddatli hamkorlik o'rnatildi Rim klubi. Holbuki Georgescu-Roegenning o'z magnum opusi hisobotida asosiy oqim (neoklassik) iqtisodchilari tomonidan deyarli sezilmay qoldi O'sishning chegaralari, 1972 yilda Rim klubi tomonidan nashr etilgan, iqtisodiy kasbda shov-shuvga sabab bo'lgan narsa.^[42] Hisobotdan keyin yuzaga kelgan qizg'in tortishuvlarda Jorjesku-Rojen o'zini asosan klub bilan bir tomonda ko'rdi va asosiy iqtisodchilarga qarshi chiqdi. Tabiiy ittifoqdoshi bilan birlashib, u klubga yaqinlashdi va u erda a'zo bo'ldi. Jorjesku-Rogenning nazariy faoliyati klubga katta ta'sir ko'rsatdi. Hamkorlikning yana bir muhim natijalaridan biri polemikaga oid keskin va polemik maqolaning nashr etilishi bo'ldi Energiya va iqtisodiy afsonalar, bu erda Georgescu-Regen asosiy iqtisodchilar va boshqa turli munozarachilar bilan bahslashdi.^[43] Ushbu maqola 1970-yillarda katta auditoriyani topdi. Keyinchalik klub bilan hamkorlik sustlashdi: Jorjesku-Rojen aniq o'sishga qarshi siyosiy pozitsiyani qo'llamagani uchun klubni tanqid qildi; u shuningdek klubning elitistiga shubha bilan qaradi va texnokratik ko'pgina mavhum kompyuter simulyatsiyalarini yaratish orqali global ijtimoiy voqelikni kuzatib borish va boshqarish uchun harakat qilish uslubi jahon iqtisodiyoti va keyin barcha topilmalarni keng ommaga e'lon qiling. 1980-yillarning boshlarida partiyalar nihoyat ajralib ketishdi.^{[41][21]:33f[44]:11f}

Martines-Alier ekologik iqtisodiyotni ham, degregatsiya harakatini ham harakatlantiruvchi kuch bo'lib kelgan. Shuningdek, u Georgescu-Roegengacha bo'lgan turli xil ekologik nazariyotchilarning tarixiy tadqiqotini nashr etdi.^[8]

Kontinental Evropada Georgesku-Roegen va uning faoliyati 1970-yillardan ta'sirga ega bo'ldi. Georgescu-Roegen ma'ruza qilganida Jeneva universiteti 1974 yilda Shveytsariyada u yosh va yangi tugatgan frantsuz tarixchisi va faylasufida katta taassurot qoldirdi Jak Grinvald.^[45]:15f Ikki tomon o'rtasidagi hamkorlik va do'stlik natijasida Jorjesku-Rojening maqolalari frantsuz tiliga tarjima qilingan. Demain la décroissance: Entropiya - Ekologiya - Ekonomi ("Ertaga, pasayish: Entropiya - Ekologiya - Iqtisodiyot"), 1979 yilda nashr etilgan.^{[46][eslatma 1]} Uning Rim klubiga aloqadorligiga o'xshash (yuqoriga qarang ), Georgescu-Roegenning maqolasi Energiya va iqtisodiy afsonalar uning qarashlarini keyingi izdoshlari orasida tarqatishda hal qiluvchi rol o'ynadi o'sish harakati.^[43][40]:544 1980-yillarda Georgesku-Roegen Kataloniyaning qishloq xo'jaligi iqtisodchisi va iqtisodiy fikr tarixchisi bilan uchrashdi va do'stlashdi Xuan Martines-Alier, kim tez orada ikkala shakllanishida harakatlantiruvchi kuchga aylanadi Xalqaro ekologik iqtisodiyot jamiyati va degregatsiya harakati.^{[19]:307–310[47]:2} Degrowth harakati 2000-yillarning boshlarida Frantsiya va Italiyada shakllanganligi sababli, harakatning etakchi frantsuz chempioni Serj Latoush Georgescu-Roegenni "o'sishning asosiy nazariy manbai" deb hisoblagan.^[48]:13–16 Xuddi shunday, italiyalik o'sish nazariyotchisi Mauro Bonaiuti Georgescu-Roegenning ishini "degregatsiya istiqbolining analitik asoslaridan biri" deb hisoblagan.^[21]:xi

Rim klubi va bir necha evropalik olimlar bilan aloqalaridan tashqari, Georgesku-Rogen Vanderbiltda yillar davomida yolg'iz odam bo'lib qoldi. U kamdan-kam hollarda hamkasblari va talabalari bilan doimiy ravishda olib borgan ishlarini muhokama qildi va o'z faoliyati davomida juda kam qo'shma loyihalarda hamkorlik qildi. Bundan tashqari, bir nechta mustaqil manbalar Jorjesku-Rogenning murosasiz xarakteri va yomon xulq-atvori uni muomala qilish uchun juda yoqimsiz tanishga aylantirganligi haqidagi kuzatuvni tasdiqlaydi. Uning ochiq va talabchan xatti-harakati akademik va boshqa joylardagi odamlarning ko'pini xafa qilishga moyil bo'lib, shu bilan uning ta'siri va mavqeiga putur etkazdi.^{[24]:16–18[37]:126f[11]:xvii[19]:310f[31][41]}

1976 yilda Jorjesku-Rojen rasmiy ravishda nafaqaga chiqqanida, uning sharafiga Vanderbiltdagi uchta hamkasbi tomonidan simpozium tashkil qilingan va u erda taqdim etilgan hujjatlar keyinchalik antologiya sifatida nashr etilgan.^[49] Nomzod iqtisodchilar orasida to'rtdan kam bo'lmagan Nobel mukofoti laureatlari bor edi;^[16]:150 Ammo Vanderbiltdagi Georgesku-Roegenning bo'limidagi hamkasblaridan birortasi ishtirok etmadi, shu paytgacha bu narsa uning ijtimoiy va akademik izolyatsiyasining isboti sifatida qabul qilindi.^[31]:14f

Pensiya, keyingi yillar va o'lim

1976 yilda Jorjesku-Rojen Vanderbiltdan rasmiy ravishda nafaqaga chiqqanidan so'ng, u yashashni va ishlashni davom ettirdi zaxm 1994 yilda vafotigacha Nashvildagi uyida. Keyingi yillarda u o'z qarashlarini kengaytirib, rivojlantirgan bir necha maqola va maqolalar yozdi.^{[50][51][52][53][2]} U shuningdek, ozgina do'stlari va sobiq hamkasblari bilan juda ko'p yozishmalar o'tkazgan.^{[21]:222–241}

1988 yilda Georgescu-Roegen yangi tashkil etilgan akademik jurnalning tahririyat kengashiga taklif qilindi Ekologik iqtisodiyot tomonidan nashr etilgan Xalqaro ekologik iqtisodiyot jamiyati; ammo jurnalni va jamiyatni tashkil qilayotgan odamlarning aksariyati Georgesku-Roegenning ishini tan olsalar va hayratga solsalar ham, u taklifnomani rad etdi: U jurnalni ham, jamiyatni ham bu kabi tushunchalarni targ'ib qilish uchun vosita deb bildi. barqaror rivojlanish va barqaror iqtisodiyot, tushunchalarni o'zi noto'g'ri va noto'g'ri deb rad etdi (ikkalasini ham quyida ko'ring) Bu yerga va Bu yerga ). Jorjesku-Rojen yanada ulkan maqsadlarni ko'zlagan edi: U amaldagi, ammo nuqsonli, asosiy paradigmani bekor qilishni va almashtirishni xohladi. neoklassik iqtisodiyot o'zining "bioekonomikasi" bilan (pastga qarang ); iqtisodiyotni iloji boricha tezroq pastga tushirish (tushirish)pastga qarang ); va emas shunchaki biron bir ashaddiy va ahamiyatsiz darajaga tushib qolish kerak, shuning uchun u iqtisodiy sub-intizom kabi ishongan ekologik iqtisodiyot.^{[40]:547[41]:2271[21]:41–48[54]:146}

Georgescu-Roegen umrida qochib ketgan Ruminiyadagi kommunistik diktaturadan omon qolish uchun etarlicha uzoq yashadi (yuqoriga qarang ). U hatto vatanidan kechikib tan olingan: Berlin devorining qulashi va keyingi Ruminiya inqilobi 1989 yilda Georgescu-Roegen saylandi Ruminiya akademiyasi Buxarestda. U saylanganidan mamnun edi.^[24]:16

Uning so'nggi yillari dunyodan ajralib qolish va ajralib chiqish bilan ajralib turardi. Hozirga qadar Georgesku-Rogen keksa odam edi. Uning ortida samarali va muvaffaqiyatli akademik martaba bo'lgan bo'lsa-da, u o'z hayoti davomida u kutganidek tarqatish va e'tirof etilmagani uchun hafsalasi pir bo'ldi. U uzoq vaqtdan beri oqimga qarshi yurganiga ishongan. U o'zini omadsizga o'xshatganidek bid'atchi va afsonaviy shahid fanidan Italiya Uyg'onish davri, Georgesku-Rojen g'azablandi va xitob qildi: "E pur si muove odatda bog'liqdir Galiley, garchi bu so'zlar oxirgi aytilgan bo'lsa ham Jiordano Bruno ustida yonayotgan qoziq!"^[32]:154 U o'zining hayotiy faoliyatida keng jamoatchilikni ogohlantirish va o'zini juda xavotirga solayotgan mineral-xom ashyoning tugashi haqida odamlarning fikrlarini o'zgartirish bo'yicha muvaffaqiyatsizlikka uchraganini anglab etdi. U nihoyat buni tushundi falsafiy pessimizm Ehtimol, o'zi kabi bir necha yolg'iz ziyolilar tomonidan ma'qullanadigan pozitsiya bo'lishi mumkin, ammo odatda bunday pozitsiyadan qochishadi tabu kengroq insoniyat madaniyatida: "[A] pessimistga yomon xabar etkazuvchi sifatida qaraladi va ... uni hech qachon kutib olishmaydi ...", - deya afsus bilan u.^[55]:165 Shunga qaramay, u o'zining chuqur ko'ngli va ko'ngli qolganiga qaramay, jismonan imkoni bor ekan, o'z qarashlarini yozishni va targ'ib qilishni davom ettirdi.^[7]:79

Oxir oqibat uning salomatligi yomonlashdi. U juda kar bo'lib qoldi va diabet tufayli yuzaga kelgan asoratlar zinadan ko'tarila olmadi. Oxirgi yillarda u o'zini butunlay izolyatsiya qildi. U odamlarning barcha aloqalarini uzdi, hatto uning sobiq hamkasblari va uning iqtisodga qo'shgan hissasini qadrlagan talabalari bilan ham aloqalarini uzdi. U 88 yoshida o'z uyida achchiq va (deyarli) yolg'izlikda vafot etdi. Uning rafiqasi Otiliya undan to'rt yilgacha omon qoldi. Er-xotinning bolalari yo'q edi.^{[16]:154[24]:18[21]:37}

Jorjesku-Rogen haqidagi obzor esselarida, Xerman Deyli vafot etgan o'qituvchisi va ustozi haqida hayrat bilan yozib, "U ko'p narsani talab qildi, lekin u ko'proq berdi" degan xulosaga keldi.^[16]:154

Ish

Iqtisodchi sifatida ishida Georgesku-Rogen ta'sir ko'rsatdi Ernst Mach falsafasi va keyingi maktab mantiqiy pozitivizm Machdan olingan. Jorjesku-Rigen yana ikkita asosiy ilhom manbai, ya'ni Karl Pirson va Albert Eynshteyn, shuningdek, asosan Machian dunyoqarashiga ega edi. "Mening falsafam Masih ruhida: u ... asosan faktlar o'rtasidagi munosabatlarning aniq tahliliy tasvirlari bilan bog'liq."^[32]:129f Ikkala tanqidning ko'p qismi neoklassik iqtisodiyot va of Marksizm ushbu dunyoqarashga asoslangan edi.^[24]:40

Ikkinchi Jahon Urushidan keyin AQShga kelib, Jorjesku-Rojen tez orada uni hukmron nazariy maktab bilan ziddiyatga keltirdi. neoklassik iqtisodiyot mamlakatda. Ruminiyada, kam rivojlangan va dehqonlar ustun bo'lgan iqtisodiyotda yashab, u neoklassik iqtisodiyot faqat rivojlangan kapitalistik iqtisodiyotda hukmron bo'lgan ijtimoiy sharoitlarni tushuntirishi mumkinligini tushundi, ammo boshqa institutsional sharoitlarda emas. Shuningdek, u abstraktning tobora ko'payib borayotganiga tanqidiy munosabatda bo'ldi algebraik formalizm ijtimoiy haqiqatning hech qanday dalillariga asoslanmagan. Ushbu ikkala masala ham uni asosiy neoklassik iqtisodiy tahlil e'tibordan chetda qoldirgan yoki noto'g'ri ko'rsatib yuborgan ijtimoiy hodisalarga diqqatli qildi.^{[32]:129f[41]:2273}

Jorjesku-Rogenning sof nazariyadagi dastlabki yillarida, 1960-yillarda uning dehqonlar iqtisodiyoti to'g'risida yozgan asarlari orqali uzluksiz yo'l bosib o'tishi, hayotining so'nggi 25 yilida entropiya va bioekonomika bilan mashg'ul bo'lishiga olib keladi degan fikrlar ilgari surilgan.^[4]:137f

Magnum opus yoqilgan Entropiya qonuni va iqtisodiy jarayon

Georgesku-Rojenning o'z eslashiga ko'ra, u taqdim etgan g'oyalar paradigmatik magnum opus uning fikrida yakuniy nashrdan oldin yigirma yil yoki undan ko'proq vaqt davomida ishlab chiqilgan.^[13]:xiv Uning ijodi uchun eng muhim uchta ilhom manbai bo'lgan Emil Borel monografiya termodinamika u Parijda o'qiyotganda o'qigan (yuqoriga qarang ); Jozef Shumpeter Qaytarib bo'lmaydigan evolyutsion o'zgarishlarga xos bo'lgan nuqtai nazar kapitalizm; va Ruminiyaning tarixiy yozuvlari Ploeshti shahridagi yirik neftni qayta ishlash zavodlari ikkala jahon urushida ham strategik harbiy hujumlarning maqsadiga aylanmoqda, ijtimoiy ziddiyatlarda tabiiy resurslarning ahamiyatini isbotlovchi.^{[32]:146,153[55]:161f[4]:139f[2]:185f,196f[30]:6}

The shortcomings of both neoclassical economics and of Marxism

Georgescu-Roegen outlines that both main streams of economic thought having dominated the world since the end of the 19th century – namely neoklassik iqtisodiyot va Marksizm – share the shortcoming of not taking into account the importance of natural resources in man's economy.^[13]:2 Hence, Georgescu-Roegen engages himself in an intellectual battle with two fronts.

The relevance of thermodynamics to economics

The physical theory of thermodynamics is based on two laws: The first law states that energy is neither created nor destroyed in any isolated system (a conservation principle). The second law of thermodynamics – also known as the entropy law – states that energy tends to be degraded to ever poorer qualities (a degradation principle).

Georgescu-Roegen argues that the relevance of termodinamika to economics stems from the physical fact that man can neither create nor destroy matter or energy, only transform it. The usual economic terms of 'production' and 'consumption' are mere verbal conventions that tend to obscure that nothing is created and nothing is destroyed in the economic process – everything is being transformed.^[13]:280

The science of thermodynamics features a kosmologiya of its own predicting the heat death of the universe: Any transformation of energy – whether in nature or in human society – is moving the universe closer towards a final state of inert physical uniformity and maximum entropiya. According to this cosmological perspective, all of man's economic activities are only speeding up the general march against a future planetary heat death locally on earth, Georgescu-Roegen submits.^{[13]:276–283} This view on the economy was later termed 'entropy pessimism'.^[14]:116 Some of Georgescu-Roegen's followers and interpreters have elaborated on this view.^{[56]:33–43[6]:107–112[28]:46–49[25]:106–109}

Conceptions of scarcity

Introducing the term 'low entropy' for valuable Tabiiy boyliklar, and the term 'high entropy' for valueless chiqindilar va ifloslanish, Georgescu-Roegen explains that all the economic process does from a physical point of view is to irreversibly transform low entropy into high entropy, thereby providing a flow of natural resources for people to live on. The irreversibility of this economic process is the reason why natural resources are scarce: Qayta ishlash of material resources is possible, but only by using up some energy resources plus an additional amount of other material resources; va energiya manbalari, o'z navbatida, umuman qayta ishlanishi mumkin emas, lekin ular sifatida tarqatiladi chiqindi issiqlik (according to the entropy law).^{[13]:277–282}

The sun will continue to shine on earth for billions of years to come.

Georgescu-Roegen points out that the earth is a yopiq tizim in the thermodynamic sense of the term: the earth exchanges energy, but not matter (practically) with the rest of the universe. Hence, mainly two sources of low entropy are available to man, namely the stock of mineral resources in the crust of the earth; and the flow of radiation, received from the quyosh. Since the sun will continue to shine for billions of years to come, the earth's mineral stock is the scarcer one of these two main sources of low entropy. Whereas the stock of minerals may be extracted from the er qobig'i at a rate of our own choosing (practically), the flow of solar radiation arrives at the surface of the earth at a constant and fixed rate, beyond human control, Georgescu-Roegen maintains. This natural 'asymmetry' between man's access to the stock of minerals and the flow of solar energy accounts for the historical contrast between urban and rural life: The busy urban life, on the one hand, is associated with industry and the impatient extraction of minerals; the tranquil rural life, on the other hand, is associated with agriculture and the patient reception of the fixed flow of solar energy. Georgescu-Roegen argues that this 'asymmetry' helps explain the historical subjection of the countryside by the town since the dawn of civilisation, and he criticises Karl Marks for not taking this subjection properly into account in his theory of tarixiy materializm.^[13]:313

Modern mechanised agriculture relies heavily on mineral inputs.

Georgescu-Roegen explains that modern mexanizatsiyalashtirilgan qishloq xo'jaligi has developed historically as a result of the growing pressure of population on arable land; but the relief of this pressure by means of mechanisation has only substituted a scarcer source of input for the more abundant input of solar radiation: Mashinasozlik, chemical fertilisers va pestitsidlar all rely on mineral resources for their operation, rendering modern agriculture – and the industrialised food processing and distribution systems associated with it – almost as dependent on earth's mineral stock as the industrial sector has always been. Georgescu-Roegen cautions that this situation is a major reason why the tashish hajmi of earth is decreasing.^{[13]:303[56]:136–140[12]:163f[8]:20–44[57]:10f} Tasirida, overpopulation on earth is largely a dynamic long run phenomenon, being a by-product of ever more constraining mineral scarcities.^{[13]:20f[58]:32–34}

The production process and the flow-fund model

In the 1965 Georgescu-Roegen presented the flow-fund model at the Conference of the International Economic Association that took place in Rome.^[59] His analysis of the production process, based on the flow-fund model, highlights the relationship between productive efficiency and the organization of production thanks to the focus on the temporal and organizational aspects of production processes. According to Georgescu-Roegen’s definition, flows are utilized in only one process as input, or they can emerge from a single process as output. While, funds enter and leave the production process, providing their services in several processes over time (e.g., workers, land and capital equipment).^[43]In the fund-flow approach, the production process is represented by a functional:^[13]:236

O(t) = Λ[G1(t), G2(t), ..., GI(t), F1(t), F2(t), ..., FH(t), U1(t), U2(t), ..., UK(t)],

where O(t) is a function describing at any time t the cumulative quantity of the output (e.g. the total quantity of tables produced in the process of table production); Gi(t) are time functions indicating, at any t, the cumulative quantity of the i-th outflow (e.g. waste, secondary products, emissions); Fh(t) are time functions indicating the cumulative quantity of the h-th inflow; finally, Uk(t) are functions indicating, at any time t, the degree of use of the k-th fund.The conceptualization of the production process in the fund-flow model allows the consideration of the way in which indivisible and complementary inputs and processes are combined in order to minimize the inactivity times of tools, to increase degree of their utilization and to decrease the duration of processes. In particular Georgescu-Roegen shows that the flow-fund model makes it possible to analyze the differences between the agriculture production, craft production and industrial production (the factory system). The size of the production unit reflects the need to minimize both idle times and under-utilization of funds, by balancing the productive capacities in the different phases. In the presence of specialized and indivisible funds, that characterize industrial processes, a high volume of production is necessary to make compatible their different productive capacities and to overcome bottlenecks. Once a scale is established that eliminates idle time for equipment, any expansion has to occur at discrete jumps of multiples of the scale achieved.^[60]:308–9 The factory system represents an attempt to overcome the problem of the indivisibility and complementarity, by reducing at minimum periods the idle times of funds. As stressed by Georgescu-Roegen, the factory system is not a technological innovation; it is rather an "economic" and organizational innovation. According to Georgescu-Roegen, it is, together with money, one of the most important organizational and economic innovations of human beings.^[59]:68 From the ‘80s numerous economists have been working on Georgesu-Roegen’s flow-fund model.^[2-eslatma]. In 1992 Mario Morroni presented a development of the flow-fund model for applied analysis.^[62] This model has been implemented in some case studies regarding the textile industry, electronic devices for telecommunication industry,^[62][71] poyabzal sanoati^[72] and tie industry.^[73]

Georgescu-Roegen's model of the economy grew out of his dissatisfaction with neoclassical production theory shuningdek kirish-chiqish modeli of the economy, developed by Nobel mukofoti laureat Vasili Leontiv. Georgescu-Roegen realised that production cannot be adequately described by stocks of equipment and inventories only, or by flows of inputs and outputs only. It was necessary to combine these two descriptions. In order to complete the picture, it was also necessary to add the new concept of a 'fund'.^{[24]:65–71[4]:147–149[38]:70–72[74]:106–109}

In Georgescu-Roegen's flow-fund model of production, a fund factor is either labour power, farmland, or man-made capital providing a useful service at any point in time. A 'stock' factor is a material or energy input that can be decumulated at will; a 'flow' factor is a stock spread out over a period of time. The fund factors constitute the agents of the economic process, and the flow factors are used or acted upon by these agents. Unlike a stock factor, a fund factor cannot be used (decumulated) at will, as its rate of utilisation depends on the distinct physical properties of the fund (labour power and farmland, for instance, may run the risk of overuse and exhaustion if proper care is not taken).

Natural resources flow through the economy and end up as waste and pollution.

Contrary to neoclassical production theory, Georgescu-Roegen identifies nature as the exclusive primary source of all factors of production. Ga ko'ra termodinamikaning birinchi qonuni, matter and energy are neither created nor destroyed in the economy (the conservation principle). Ga ko'ra termodinamikaning ikkinchi qonuni – the entropy law – what happens in the economy is that all matter and energy is transformed from states available for human purposes to states unavailable for human purposes (the degradation principle). This transformation constitutes a unidirectional and irreversible process. Consequently, valuable Tabiiy boyliklar ('low entropy') are procured by the input end of the economy; the resources flow through the economy, being transformed and manufactured into goods along the way; and unvaluable chiqindilar va ifloslanish ('high entropy') eventually accumulate by the output end. Mankind lives in, by, and of nature, and we return our residues to nature. By so doing, the entropy of the combined nature-economy system steadily increases.

The presence of natural resource flows in Georgescu-Roegen's model of production (production function) differentiates the model from those of both Keynesian macroeconomics, neoklassik iqtisodiyot, shu qatorda; shu bilan birga klassik iqtisodiyot, including most – though not all – variants of Marksizm.^[3-eslatma] Faqatgina ekologik iqtisodiyot are natural resource flows positively recognised as a valid theoretical basis for economic modelling and analysis.^{[8]:1–3[17]:57–62[10]:266–268}

Later, Georgescu-Roegen's production model formed the basis of his criticism of neoclassical economics (pastga qarang ).

Man's economic struggle and the social evolution of mankind (bioeconomics)

Marx was optimistic about the future communist society; but Georgescu-Roegen objected that social conflict will never be eliminated.

In his social theory, Georgescu-Roegen argues that man's economic struggle to work and earn a livelihood is largely a continuation and extension of his biological struggle to sustain life and survive. This biological struggle has prevailed since the dawn of man, and the nature of the struggle was not altered by the invention of pul ayirboshlash vositasi sifatida. Unlike animals, man has developed exosomatic instruments, that is, tools and equipment. These instruments are produced by man and are not a part of his body. At the same time, production is a social, and not an individual, undertaking. This situation has turned man's struggle to sustain life and survive into a social conflict which is unique when compared to animals. Contrasting his own view with those of Karl Marks, Georgescu-Roegen asserts:

[L]ike Marx, I believe that the social conflict is not a mere creation of man without any root in material human conditions. But unlike Marx, I consider that, precisely because the conflict has such a basis, it can be eliminated neither by man's decision to do so nor by the social evolution of mankind.^[13]:306

When man (some men) attempts to radically change the distribution of access to material resources in society, this may result in wars or revolutions, Georgescu-Roegen admits; but even though wars and revolutions may bring about the intended redistributions, man's economic struggle and the social conflict will remain. There will be rulers and ruled in any social order, and the ruling is largely a continuation of the biological struggle of sustaining life and survive, Georgescu-Roegen claims. Under these material conditions, the ruling classes of past and present have always resorted to force, ideology and manipulation to defend their privileges and maintain the acquiescence of the ruled. This historical fact does not end with kommunizm, Georgescu-Roegen points out; quite the opposite, it goes on during communism, and beyond it as well. It would be contrary to man's biological nature to organise himself otherwise.^{[13]:306–315[24]:120–124[78]}

Later, Georgescu-Roegen introduced the term 'bioeconomics' (short for 'biological economics') to describe his view that man's economic struggle is a continuation of the biological struggle.^{[43]:369[32]:152–154[4]:149[28]:1f} In his final years, he planned to write a book on the subject of bioeconomics, but due to old age, he was unable to complete it.^[24]:120 He did manage to write a sketch on it, though.^[51]

Population pressure, mineral resource exhaustion and the end of mankind

Georgescu-Roegen takes a dismal view of the future of mankind. On the one hand, his general argument is that the tashish hajmi of earth – that is, earth's capacity to sustain human populations and consumption levels – is decreasing as earth's finite stock of mineral resurslar are being extracted and put to use; but on the other hand, he finds that restraining ourselves collectively on a permanent and voluntary basis for the benefit of future generations runs counter to our biological nature as a species. We cannot help ourselves. Binobarin, jahon iqtisodiyoti will continue growing until its inevitable and final collapse. From that point on, he predicts, ever deepening scarcities will cause widespread misery, aggravate social conflict throughout the globe, and intensify man's economic struggle to work and earn a livelihood. A prolonged 'biological spasm' of our species will follow, ultimately spelling the end of mankind itself, as man has already become completely and irreversibly dependent on the industrial economy for his biological existence. We are not going to make it. We are doomed to downfall, destruction, and demise. Predicts Georgescu-Roegen:

If we abstract from other causes that may knell the death bell of the human species, it is clear that natural resources represent the limitative factor as concerns the life span of that species. ... By using these resources too quickly, man throws away that part of quyosh energiyasi that will still be reaching the Earth for a long time after he has departed. And everything man has done during the last two hundred years or so puts him in the position of a fantastic spendthrift. ... The realization of these truths will not make man willing to become less impatient and less prone to hollow wants.^[13]:21
...
Aholining bosimi va texnologik taraqqiyot olib kelish ceteris paribus the career of the human species nearer to its end only because both factors cause a speedier decumulation of its dowry [of mineral resources]. ... [W]e must not doubt that, man's nature being what it is, the destiny of the human species is to choose a truly great but brief, not a long and dull, career.^[13]:304

Georgescu-Roegen's radically pessimistic 'existential risk' perspective on global mineral resource exhaustion was later countered by Robert Ayres (pastga qarang ).

Work after magnum opus

In the years following the publication of his magnum opus in 1971 and until his death in 1994, Georgescu-Roegen published a number of articles and essays where he further expanded on and developed his views.^[4-eslatma]

Criticising neoclassical economics (weak versus strong sustainability)

Criticising neoclassical economics, Georgescu-Roegen argues that neoclassical production theory is false when representing the economy as a mechanical, circular and closed system, with no inlets and no outlets.^[43]:347f A misrepresentation such as this fails to take into account the exhaustion of mineral resurslar at the input end, and the building up of chiqindilar va ifloslanish at the output end. In Georgescu-Roegen's view, the economy is represented more accurately by his own flow-fund model of production (yuqoriga qarang ).

Solow is a leading growth theorist in the neoclassical tradition.

In addition, Georgescu-Roegen finds that neoclassical economics tends to overlook, or, at best, to misrepresent the problem of how to ajratmoq the exhaustible mineral resources between present and future generations. Georgescu-Roegen points out that the market mechanisms of supply and demand are systematically unable to work out the intergenerational allocation problem in a satisfactory way, since future generations are not, and cannot be, present on today's market. This anomaly of the market mechanisms – or ecological market failure – is described by Georgescu-Roegen as 'a dictatorship of the present over the future'.^{[43]:375[79]:105[58]:33f[8]:156–160[54]:143f} On this issue, notable economists and Nobel mukofoti laureatlari Robert Solou va Jozef Stiglitz, Georgescu-Roegen's two main adversaries in academia in the 1970s, have stated their account of the mainstream neoclassical approach to the economics of tugaydigan resurslar: They both claim that across the board substitutability of man-made capital for natural capital constitutes a real possibility. Hence, any concern with intergenerational allocation of the mineral stock should be relaxed somewhat (according to Solow);^[80]:366f or even ignored altogether (according to Stiglitz).^[81]:61f

The position of Solow and Stiglitz (as well as other, like-minded theorists in the neoclassical tradition) was later termed 'weak sustainability' by environmental economist Kerry Turner.^[82]:9–13

The Breit-Wheeler jarayoni represents the only known example of a process where energy (fotonlar ) is transformed into mass (pozitron -elektron pairs); but even in this special experimental case, the resulting elementar zarralar cannot combine to form atomic structures having economic value. A process where pure energy is transformed into useful materials remains to be discovered.

In response to the position of Solow and Stiglitz, Georgescu-Roegen argues that neoclassical economists generally fail to realise the important difference between material resources and energy resources in the economic process. This is where his flow-fund model of production comes into play (yuqoriga qarang ). Georgescu-Roegen's point is that only material resources can be transformed into man-made capital. Energy resources, on the other hand, cannot be so transformed, as it is physically impossible to turn energy into matter, and matter is what man-made capital is made up of physically. The only possible role to be performed by energy resources is to assist – usually as yoqilg'i yoki elektr energiyasi – in the process of transforming material resources into man-made capital. In Georgescu-Roegen's own terminology, energy may have the form of either a stock factor (mineral deposits in nature), or a flow factor (resources transformed in the economy); but never that of a fund factor (man-made capital in the economy). Hence, substituting man-made capital for energy resources is physically impossible.

Furthermore, not all material resources are transformed into man-made capital; instead, some material resources are manufactured directly into consumer goods having only a limited durability. Finally, in the course of time, all man-made capital depreciates, wears out and needs replacement; but both old and new man-made capital is made out of material resources to begin with. All in all, the economic process is indeed a process with steadily increasing entropy, and the 'mechanical' notion of across the board substitutability prevalent in neoclassical economics is untenable, Georgescu-Roegen submits.^{[43]:359–363[79]:98[37]:127–136[78]}

Contrary to the neoclassical position, Georgescu-Roegen argues that flow factors and fund factors (that is, natural resources and man-made capital) are essentially bir-birini to'ldiruvchi, since both are needed in the economic process in order to have a working economy. Georgescu-Roegen's conclusion, then, is that the allocation of exhaustible mineral resources between present and future generations is a large problem that cannot, and should not, be relaxed or ignored: "There seems to be no way to do away with the dictatorship of the present over the future, although we may aim at making it as bearable as possible."^[79]:105 Georgescu-Roegen's followers and interpreters have since been discussing the existential impossibility of allocating earth's finite stock of mineral resources evenly among an unknown number of present and future generations. This number of generations is likely to remain unknown to us, as there is no way – or only little way – of knowing in advance if or when mankind will ultimately face extinction. Tasirida, har qanday conceivable intertemporal allocation of the stock will inevitably end up with universal economic decline at some future point.^{[15]:369–371[56]:253–256[12]:165[8]:168–171[4]:150–153[25]:106–109[40]:546–549[54]:142–145} This approach to mankind's prospects is absent in neoclassical economics.

The position of Georgescu-Roegen, including his criticism of neoclassical economics, was later termed 'strong sustainability' by Kerry Turner.^[82]:13–15 Later still, Turner's taxonomy of 'weak' and 'strong' sustainability was integrated into ecological economics.^{[3]:205–209[83]:14–19[14]:115f[84][85]} However, contrary to the widely established use of Turner's simplifying taxonomy, Georgescu-Roegen never referred to his own position as 'strong sustainability' or any other variant of sustainability. Aksincha. Georgescu-Roegen flatly dismissed any notion of barqaror rivojlanish as only so much 'ilon moyi ' intended to deceive the general public.^{[4]:153[40]:547} In his last years, he even denounced the notion bitterly as "one of the most toxic recipes for mankind": There can be no such thing as a 'sustainable' rate of extraction and use of a finite stock of non-renewable mineral resources  – har qanday rate will diminish the remaining stock itself.^[21]:239f Binobarin, Sanoat inqilobi has brought about unsustainable economic development in the world (pastga qarang ).

Criticising Daly's steady-state economics

Leading ecological economist and barqaror holat nazariyotchisi Xerman Deyli is a former student and protégé of Georgescu-Roegen. In the 1970s, Daly developed the concept of a barqaror iqtisodiyot, by which he understands an economy made up of a constant stock of physical wealth (man-made capital) and a constant stock of people (population), both stocks to be maintained by a minimal flow of natural resources (or 'throughput', as he terms it). Daly argues that this steady-state economy is both necessary and desirable in order to keep human environmental impact within biophysical limits (however defined), and to create more allocational fairness between present and future generations with regard to mineral resource use.^[15] In several articles, Georgescu-Roegen criticised his student's concept of a steady-state economy.^{[43]:366–369[50]:270[79]:102–105[55]:167f[2]:194[40]:547[54]:140–148}

Konchilik activities are subject to diminishing returns.

Georgescu-Roegen argues that Daly's steady-state economy will provide no ecological salvation for mankind, especially not in the longer run. Due to the geologic fact that mineral ores are deposited and concentrated very unevenly in the crust of the earth, prospecting for and extraction of mineral resources will sooner or later be faced with the principle of kamayib borayotgan daromad, whereby extraction activities are pushed to still less accessible sites and still lower grades of ores. In the course of time, then, extraction costs and market prices of the incremental amount of resources will tend to increase. Eventually, all minerals will be exhausted, but the iqtisodiy exhaustion will manifest itself long before the jismoniy exhaustion provides the ultimate backstop for further activity: There will still be deposits of resources left in the crust, but the geologic concentration of these deposits will remain below the critical cutoff grade; hence, continued extraction will no longer pay off, and the market for these resources will then collapse. This long-term dynamics will work itself through any economic (sub-)system, regardless of the system's geographical location, its size and its state of development (whether a progressive, a steady or a declining state). In effect, the arguments advanced by Daly in support of his steady-state economy apply with even greater force in support of a declining-state economy, Georgescu-Roegen points out: When the overall purpose is to ration and stretch mineral resource use for as long time into the future as possible, zero economic growth is more desirable than growth is, true; ammo salbiy o'sish hali ham yaxshi! In this context, Georgescu-Roegen also criticises Daly for not specifying at what levels man-made capital and human population are to be kept constant in the steady-state.

Instead of Daly's steady-state economics, Georgescu-Roegen proposed his own so-called 'minimal bioeconomic program ', featuring quantitative restrictions even more severe than those propounded by Daly.^{[43]:374–379[4]:150–153[44]:13f[54]:142–146[5-eslatma]}

Herman Daly on his part has readily accepted his teacher's judgement on this subject matter: In order to compensate for the principle of kamayib borayotgan daromad in mineral resource extraction, an ever greater share of capital and labour in the economy will gradually have to be transferred to the mining sector, thereby skewing the initial structure of any steady-state system. Even more important is it that the steady-state economy will serve only to postpone, and not to prevent, the inevitable mineral resource exhaustion anyway. "A steady-state economy cannot last forever, but neither can a growing economy, nor a declining economy", Daly concedes in his response to Georgescu-Roegen's criticism. In the same turn, Daly confirms Georgescu-Roegen's general argument that earth's tashish hajmi is decreasing as mankind is extracting the finite mineral stock.^{[15]:369–371}

Likewise, several other economists in the field besides Georgescu-Roegen and Daly have agreed that a steady-state economy does not by itself constitute a long-term solution to the 'entropy problem' facing mankind.^{[58]:30–34[12]:165–167[86]:90f[6]:105–107[7]:75f[87]:270[40]:548[57]:37}

Technology assessments in historical perspective

In his technology assessments, Georgescu-Roegen puts thermodynamic principles to use in a wider historical context, including the future of mankind.^{[52]:1041–1055 [88][53]:14–18 [2]:195f [3]:218f [24]:124–126}

According to Georgescu-Roegen's terminology, a technology is 'viable' only when it is able to return an energy surplus sufficiently large to maintain its own operation, ortiqcha some additional energy left over for other use. If this criterion is not met, the technology in question is only 'feasible' (if workable at all), but not 'viable'. Both viable and feasible technologies depend on a steady flow of natural resources for their operation.

Prometheus I: The mastering of fire in the Palaeolithic Era.

Georgescu-Roegen argues that the first viable technology in the history of man edi olov. By controlling fire, it was possible for man to burn a forest, or all forests. It was also possible to cook food and to obtain warmth and protection. Inspired by the ancient Greek myth of Prometey, Titan who stole fire from the gods and gave it to man, Georgescu-Roegen terms fire 'the first Promethean recipe'. According to Georgescu-Roegen, a later important Promethean recipe (technology) of the same (first) kind was chorvachilik, feeding on grass and other biomass (like fire does).

Prometheus II: The steam engine of the Industrial Revolution.

Much later in the history of man, the bug 'dvigateli came about as the crucial Promethean recipe of the ikkinchi kind, feeding on ko'mir. The invention of the steam engine made it possible to drain the groundwater flooding the mine shafts, and the mined coal could then be used as fuel for other steam engines in turn. This technology propelled the Sanoat inqilobi in Britain in the second half of the 18th century, whereby man's economy has been thrust into a long, never-to-return overshoot-and-collapse trajectory bilan bog'liq earth's mineral stock. Georgescu-Roegen lists the ichki yonish dvigateli va yadroviy bo'linish reaktori as other, later examples of Promethean recipes of the second kind, namely issiqlik dvigatellari feeding on a mineral fuel (moy va uran (ortiqcha) torium ), respectively).

Prometheus III: Solar collectors returning a sufficiently large energy output. Georgescu-Roegen believed that no technology of this kind was yet around in the world in his day.

By a Promethean recipe of the uchinchi kind, Georgescu-Roegen understands a quyosh kollektori returning a net energy output sufficiently large to supply all the energy input needed to manufacture an additional solar collector of the same kind, thereby constituting a full serial reproduction with regard to solar energy only. The fact that solar collectors of various kinds had been in operation on a substantial scale for more than a century without providing a breakthrough in energy efficiency brought Georgescu-Roegen to the conclusion that no Promethean recipe was yet around in the world in his day. Only feasible recipes for solar collectors were available, functioning like what he labelled 'parasites' with regard to the terrestrial inputs of energy for their manufacture and operation – and like any other parasite, these recipes cannot survive their host (the 'host' being the sources of the terrestrial inputs). Georgescu-Roegen believed that for a worldwide solar-powered economy to be truly energy self-supporting, a Promethean kind of solar collector had yet to be invented.^{[52]:1053–1055[32]:151[2]:196} Later, some scholars have argued that the efficiency of solar collectors has increased considerably since Georgescu-Roegen made these assessments.^{[89]:479f[27]:176f}

Georgescu-Roegen further points out that regardless of the efficiency of any particular kind of solar collector, the major drawback of solar power o'z-o'zidan when compared to terrestrial Yoqilg'i moyi va uran (ortiqcha) torium ) bo'ladi quyosh nurlanishining tarqoq, past intensivlik xususiyati. Hence, a lot of material equipment is needed as inputs at the surface of the earth to collect, concentrate and (when convenient) store or transform the radiation before it can be put to use on a larger industrial scale. This necessary material equipment adds to the 'parasitical' operation of solar power, Georgescu-Roegen maintains.^{[52]:1050[56]:196–204[3]:219[57]:12f}

By the 1990s, the technology of fusion power was still in the making. The research & development continues today...

Assessing termoyadroviy quvvat as a possible future source of energy, Georgescu-Roegen ventured the opinion that, regarding magnitlangan izolyatsiya, no reactor will ever be built to be large enough to effectively withstand and confine the vehement thermal pressure ning plasmic deuterium/tritium fusion processes through an extended period of time.^[2]:196 He did not assess the other one of the two major fusion power technologies being researched in his day – and still being researched – namely inertial qamoqdagi birlashma.

Will mankind remain confined to earth forever ... ?

All of these technology assessments have to do with energy resources only, and not with material resources. Georgescu-Roegen stressed the point that even with the proliferation of solar collectors throughout the surface of the globe, or the advent of fusion power, or both, any industrial economy will still depend on a steady flow of material resources extracted from the crust of the earth, notably metallar. He repeatedly argued his case that in the (far) future, it will be scarcity of terrestrial material resources, and not of energy resources, that will prove to impose the most binding constraint on man's economy on earth.^{[43]:377[50]:268f[52]:1049[79]:98f} As he held no kosmik targ'ibot views, Georgescu-Roegen failed to assess the (still) emerging technology of asteroid qazib olish yoki any other known type of space colonisation kabi potentials for compensating for this future scarcity constraint facing mankind: He was convinced that throughout its entire span of existence, our species will remain confined solely to earth for all practical purposes.^[51]:103f His paradigmatic vision concluded thereby.

Mistakes and controversies

The entropy law does not apply to material resources.

Georgescu-Roegen's work was blemished somewhat by mistakes caused by his insufficient understanding of the physical science of termodinamika. Ishlayotganda Entropiya qonuni va iqtisodiy jarayon (yuqoriga qarang ), Georgescu-Roegen had the firm understanding that the entropy law applies equally well to both energy resources and to material resources, and much of the reasoning in the opus rests on this understanding;^{[13]:187–195, 277–282, va boshqalar} but, regrettably for Georgescu-Roegen, this understanding was – and still is – false: In thermodynamics proper, the entropy law does apply to energy, but not to matter of macroscopic scale (that is, not to material resources).^{[90]:239–276 [25]:34–43} Later, when Georgescu-Roegen realised his mistake, his reaction passed through several stages of contemplation and refinement, ultimately leading to his formulation of a new physical law, namely the fourth law of thermodynamics. This fourth law states that complete recycling of matter mumkin emas.^[6-eslatma] The purpose of Georgescu-Roegen's proposed fourth law was to substantiate his initial claim that not only energy resources, but also material resources, are subject to general and irreversible physical degradation when put to use in economic activity. In addition, he introduced the term 'material entropy' to describe this physical degradation of material resources.^[24]:104f

Planck had used the concept of 'matter dissipation' in some of his work.

Georgescu-Roegen himself was not confident about this tentative solution to the problem. He remained embarrassed that he had misinterpreted, and consequently, overstretched the proper application of the physical law that formed part of the title of his magnum opus. He conceded that he had entered into the science of thermodynamics as something of a bold novice. Bag'ishlangan fanlararo, he was worried that fiziklar would dismiss all of his work as amateurism on this count. The predicament would trouble him for the rest of his life.^{[32]:148f[2]:196f[1][21]:238} In one of his last published articles before his death, Georgescu-Roegen described his encouragement when he had once earlier come across the concept of 'matter dissipation' used by German physicist and Nobel mukofoti laureati Maks Plank to account for the existence of irreversible physical processes where no simultaneous transformation of energy was taking place. Georgescu-Roegen found consolation in the belief that the concept of 'matter dissipation' used by a physicist of Planck's authoritative standing would decisively substantiate his own fourth law and his own concept of material entropy.^{[2]:197[28]:57–60}

Georgescu-Roegen's formulation of a fourth law of thermodynamics and the concept of material entropy soon generated a prolonged controversy, involving both physicists and ecological economists;^{[91][92][24]:103–107[26]:21–28[27][28]:56f[93]:25–29[94][95]:110[96][29]:1215–1218} but some twelve to fifteen years after Georgescu-Roegen's death, a consensus on this subject matter finally emerged along the following lines:

• U yerda only one measure of entropy in thermodynamics, and this one measure applies to both energiya va ga microscopic matter at the molecular level (kinetic gas theory); but the measure tegishli emas to macroscopic matter (matter in bulk, material resources), though it frequently appears so in the ekologik iqtisodiyot literature and elsewhere.
• The general physical degradation of material resources taking place in the economy can neither be explained nor described by the entropy law (Georgescu-Roegen's first mistake); but the fact remains that such physical degradation does take place all the time – continuously, irreversibly and in a variety of ways.
• The fourth law of thermodynamics and the concept of material entropy as proposed by Georgescu-Roegen to redress his first mistake have no scientific basis in physics whatsoever, and it was a theoretical mistake Georgescu-Roegen tomonidan bu takliflarni umuman berish (Georgescu-Roegenning ikkinchi xatosi); ammo o'z-o'zidan, bu moddiy resurslarni to'liq va doimiy ravishda qayta ishlash mumkin degani emas, chunki bu boshqa sabablarga ko'ra imkonsizdir (pastga qarang ).
• Georgesku-Rojening ikkala xatosi ham uning aybi bilan sodir bo'ldi etarli tushuncha termodinamika fizika fanidan. Birinchi navbatda fizik nazariyani etarli darajada tushunmaslik uchun yangi fizik qonunni (to'rtinchi) ishlab chiqish yomon fizika va bir xil darajada yomon iqtisodiyotdir. Bunday qurilma chegaradosh bo'lishi mumkin psevdologiya.
• Ushbu ikkita xatoni hisobga olmaganda, Georgesku-Roegenning ishi hali ham mos keladi fizikada o'rnatilgan termodinamikaning birinchi va ikkinchi qonuni bilan.

Ushbu kelishuv bilan bir qatorda, Georgesku-Rojenning iqtisodiga bag'ishlangan to'liq bob ma'qullangan holda fizika fanidan bitta boshlang'ich fizika darsligiga kiritilgan. termodinamikaning tarixiy rivojlanishi va u erda to'rtinchi qonun va moddiy entropiya haqidagi tafsilotlar (Georgesku-Rojening xatolari) chiqarib tashlangan.^{[25]:95–112}

Ayres Georgesku-Rojening pessimizmiga qarshi chiqdi va "kosmik kemalar iqtisodiyoti" tarafdori edi.

Insoniyat uchun mumkin bo'lgan kelajakdagi iqtisodiy tizimni modellashtirish, Robert Ayres moddiy resurslarni to'liq va abadiy qayta ishlashning mumkin emasligi to'g'risida Georgescu-Roegenning pozitsiyasiga qarshi chiqdi. Ayresning fikriga ko'ra, u $ a $ deb tasavvur qiladigan narsalarni ishlab chiqish mumkin Yerdagi "kosmik kemalar iqtisodiyoti" barqaror va doimiy ravishda, agar uni ta'minlash uchun etarli energiya oqimi mavjud bo'lsa (masalan, quyosh energiyasi ). Ushbu kosmik kema iqtisodiyotida barcha chiqindi materiallar vaqtincha tashlanadi va harakatsiz suv omborlarida saqlanadi - yoki u "chiqindilarni savat" deb atagan narsalar - qayta ishlashdan oldin va keyinchalik bir muncha vaqt o'tgach iqtisodiy tizimda faol foydalanishga qaytariladi. Qayta ishlash materiallari o'zlarining alohida va uzluksiz oqimini hosil qilishi uchun kerak bo'lmaydi, yoki hatto mumkin bo'lmaydi - faqat ushbu chiqindilar savatlari tezligi va qayta ishlash samaradorligini qoplash uchun etarlicha katta bo'lishi kerak. . Darhaqiqat, moddiy resurslarni to'liq va doimiy ravishda qayta ishlash kelgusidagi ushbu turdagi kosmik kemalar iqtisodiyotida mumkin bo'ladi va shu bilan eskirgan Jorjesku-Rojenning to'rtinchi termodinamik qonunini keltirib chiqaradi, deydi Eyres.^[89] Keyinchalik maqolada, Ayres kosmik kema iqtisodiyoti uchun o'z ishini qayta ko'rib chiqdi.^{[97]:290–294}

Yilda ekologik iqtisodiyot, Ayresning Jorjesku-Rogen taklif qilgan to'rtinchi qonuniga qo'shgan hissasi shundan beri "energetik dogma" ning yana bir misoli sifatida tasvirlangan:^[40]:547 Ilgari Georgescu-Roegen "energetik dogma" yorlig'ini barcha iqtisodiy faoliyatni cheklovchi omil sifatida moddiy resurslar emas, balki faqat energiya manbalari degan fikrni ilgari surgan turli xil nazariyotchilarga ilova qilgan edi.^{[52]:1024–1029[3]:211f[78][7-eslatma]} Eyres bu mavzuda g'alati odamga o'xshaydi: Jorjesku-Rojenning to'rtinchi qonunining ilmiy maqomi va asosliligi qanday bo'lishidan qat'iy nazar, bu sohadagi Georgesku-Rojendan tashqari yana bir qancha iqtisodchilar har doim to'liq va abadiy qayta ishlashning amaliy imkoniyatini inkor etadilar. qayta ishlashga sarflanadigan energiya, vaqt va ma'lumot miqdoridan qat'i nazar, har qanday iqtisodiy tizimdagi barcha moddiy resurslar.^{[15]:17f [56]:36f [12]:164–167 [6]:105–107 [98][28]:60–64 [76]:155–161 [99][57]:292–294 [100]:46–49}
