Umsebenzi ukukhiqizwa Cobb-Douglas - imodeli kwezici ezimbili

Ngaphezu eziyinkimbinkimbi multifactorial onobuhle sokukhula komnotho, ngokuvamile besebenzisa lula, kwezici ezimbili, imodeli. Cobb-Douglas - umfuziselo elibonisa ukwencika okukhipha (Q) zezici ukudala ke: zabasebenzi - (L) kanye capital investment - (K).

Zezomnotho, baye bahlongoza ongakhetha ezimbili kungenzeka ukwakhiwa kwezici ezimbili onobuhle, ikhumbula inqubekela-phambili yesayensi lwezobuchwepheshe futhi ngaphandle yokubhalisa.

Umsebenzi ukukhiqizwa Cobb-Douglas esekelwe NTP

imodeli Economic ukuthi uyakucabangela impumelelo yangempela inqubekela-phambili yesayensi lwezobuchwepheshe, abasebenzi kanye dolobha ikhiqize kakhudlwana. Ezimweni ezinjengalezi, kungenzeka ukuthola inzuzo ephakeme ngenani elifanayo wezabaSebenzi amathuluzi ukusebenza. Kulesi imodeli, ezinye izinhlobo nezinamathiselo ukusiza ukwandisa izindleko futhi unikeze imali ukonga esabeletha, nezinye - kuholela ukuncipha utshalomali. Eyokuqala hlobo utshalomali kuholela zabasebenzi ukonga, kanti eyesibili - ukuze ulondoloze dolobha.

Indlelanchubo yekusebentisa akacabangi NTP

Esimeni semakhaya model of the umnotho, lapho hhayi kunakwe intuthuko yesayensi nezobuchwepheshe, inhlokodolobha ekuqongeleleni senzeka ngaphansi izindleko njalo. Zezomnotho ukufunda ukubonisa ukuthi ukusetshenziswa le ndlela kuholela Ukwehliswa umkhiqizo wokugcina.

Ngakolunye uhlangothi, lesi simo kungase kubonakale into engekho ngokwemvelo. Kodwa eqinisweni, lesi simanga Kungenzeka ukuthi ngakolunye uhlangothi eziphoqelelwe sifinyelele STP, ngakolunye uhlangothi ke nqatshwe amabhizinisi, kusukela akukho kokuvusayo ngempumelelo ukwethulwa ezintsha ekukhiqizweni. Ngenxa yalokho, inkampani ehlupheka izindleko ezengeziwe ukuthengwa imishini emisha okuyinto alisetshenziswa inqubo ukukhiqizwa, kodwa kuphela ulenga phezu the balance sheet kanye anganciphisa ukusebenza yayo.

Kulula ukubona ukuthi kungaba khona izixazululo Lesisemkhatsini ukuthi hlanganisa izindlela ezimbili kuchazwe.

Cobb Douglas imodeli ukunquma ukukhula

Ngokokuqala ngqá kule modeli kwahlongozwa ngu UKnut Wicksell. Kodwa kuphela ngo-1928, kwathiwa ihlolwe practice, osomnotho Cobb futhi Douglas. Umsebenzi ukukhiqizwa Cobb-Douglas ukuze kutholakale izinga Imininingwane okukhipha Q kanye nenani umzamo etshaliwe dolobha (L futhi K).

Umsebenzi libukeka kanje:

Q = A × Lα × Kβ

Kuphi: Q - ivolumu zokukhiqiza;

L - Imizamo;

K - Kusisa;

A - isici zobuchwepheshe;

α - Inani zabasebenzi kuyaqina;

β - value utshalomali kuyaqina.

Ngokwesibonelo, cabanga kwesibalo Q = L0,78 K0,22. Kulesi kwesibalo singabona ukuthi umkhiqizo ingqikithi share zabasebenzi 78% kanye isabelo inhlokodolobha - 22%.

Ukulinganiselwa model of the Cobb-Douglas

Umsebenzi ukukhiqizwa Cobb-Douglas kusikisela ukulinganiselwa ezithile okufanele kucatshangelwe uma usebenzisa imodeli.

Ukukhiqizwa amavolumu zikhulisa, lapho esinye sezici uhlala ingashintshiwe, kanti eyesibili luyanda. Lona umnyombo walokho imikhawulo lokuqala nelesibili. Ngaphezu kwalokho, uma omunye izici iqinile, kanye nezinye liyaphuma, ngamunye umkhawulo iyunithi ezikhulayo isici akuyona njengoba nomphumela njengoba ukubaluleka odlule.

Ngezinye value njalo kulusizo ukwenyuka kancane we Esinye isici imbangela ekunciphiseni ukwanda okukhipha value (Q). Lona nelesine umkhawulo imodeli Cobb-Douglas.

I ukulinganiselwa lesihlanu nelesithupha basikisela ukuthi ngamunye izici zokukhiqiza kubalulekile. Okusho ukuthi, uma yezimbangela kuyinto 0, ngokulandelana, futhi Q beyoba zero.
