The kugadzirwa kushanda Cobb-Douglas - maviri-chinhu womuenzaniso

Kuwedzera kunzwisisa multifactorial yemashoko zvoupfumi kukura, kazhinji kushandisa Yokudzidza, mbiri-chinhu, muenzaniso. Cobb-Douglas - muenzaniso izvo zvinoratidza kuvimba kuti goho (Q) zvinokonzera kuti pave nayo: basa mari - (L) uye guta mari - (K).

Nezvoupfumi kunge aronga zvichibvira nzira mbiri chokuvaka maviri-chinhu yokutevedzera, kufungisisa chesayenzi uye hwokugadzira mberi uye pasina kunyoresa.

The kugadzirwa kushanda Cobb-Douglas kwakavakirwa NTP

womuenzaniso Economic kuti inorangarira nokubudirira chaicho nesayenzi uye michina mberi, basa uye guta guru hunobudirira. Mumamiriro ezvinhu akadaro, zvinokwanisika kuwana yepamusoro mari panguva iyoyo vachikanganisa basa uye kushanda zvokushandisa. In womuenzaniso ichi, dzimwe mhando pakapfava anobatsira kuwedzera mari uye kupa mari nemari achipona, dzimwe - inoenda zvinoderedza inivhesitimendi. Wokutanga mhando mari kunotungamirira basa nemari, uye wechipiri - kuponesa guta.

The kusvika haatori mashoko NTP

Munguva muenzaniso upfumi, kana asina kufungwa chesayenzi uye zvekushandisa mberi, guta kuwanda kunoitika pasi kugara mari. Nezvoupfumi kudzidza kuratidza kuti kushandiswa akadaro yokutaura kunotungamirira kuti rutapudzo yokupedzisira chigadzirwa.

Kudivi rimwe, izvi zvingaita sokurwarirwa. Asi chokwadi, chiitiko ichi ingangodaro iri ruoko rumwe waiita kuzadzisa Stp, Ukuwo zvinonzi akaramba achishandisa emakambani, sezvo hapana nzira incentives kuti pakatanga zvakagadzirwa kupinda kugadzirwa. Somugumisiro, kambani kutamburawo imwe mari kuti kutenga michina itsva iyo haina kushandiswa pakugadzira kwacho, asi chete yakaturikwa pachiyero jira kuderedza maitiro ayo.

Zviri nyore kuona kuti pangava zvenguva zvinogadzirisa kuti nokubatanidza nzira mbiri inorondedzerwa.

Cobb Douglas muenzaniso kuti asarudze kukura

Kokutanga womuenzaniso uyu wakatangwa na Knut Wicksell. Asi chete muna 1928, yakanga kuedzwawo tsika, nezvoupfumi Cobb uye Douglas. The kugadzirwa kushanda Cobb-Douglas kuona padanho zvachose goho Q uye uwandu nesimba paakapiwa guru (L uye K).

Mashandiro anotarira seizvi:

Q = A × Lα × Kβ

Apo: Q - Vhoriyamu kugadzirwa;

L - Basa;

K - Capital upfumi;

A - muzvigadzirwa chinhu;

α - ukoshi basa mari elasticity;

β - ukoshi inivhesitimendi elasticity.

Somuenzaniso, funga mukana wokuti vanhu vanga Q = L0,78 K0,22. In mukana wokuti vanhu vanga ichi tinogona kuona kuti iri zvachose chigadzirwa webasa mugove 78% uye mugove guru - 22%.

Kuitwa muenzaniso of Cobb-Douglas

The kugadzirwa kushanda Cobb-Douglas hunoratidza zvimwe zvausingakwanisi kuita kuti zvinofanira kufungwa nezvazvo apo uchishandisa muenzaniso.

Production mavhoriyamu vari kuwedzera, apo mumwe zvinhu inoramba kuzochinja, uye wechipiri inowedzerwa. Ndiyo musimboti rokutanga uye rechipiri kurambidzwa. Uyezve, kana mumwe zvinhu wakaiswa, uye vamwe rinobuda, mumwe muganhu chikwata kukura chinhu hakusi kubudirira sezvinobvira yapfuura ukoshi.

At kuramba ukoshi chakaita zvishoma nezvishoma Zvakawanikwa Chimwe chinokonzera ndiko chikonzero kuderedza vachiwedzera goho ukoshi (Q). Ndiwo yechitatu uye nekurovererwa chechina womuenzaniso Cobb-Douglas.

Rechishanu nerechitanhatu zvatisingakwanisi zvinoratidza kuti mumwe nomumwe zvinhu okuwana kunokosha. Ndiko, kana mumwe zvinhu ndiyo 0, ukuwo, uye Q achava razero.
