Umsebenzi imveliso ye Cobb-Douglas - imodeli factor-amabini

Ukongeza ukuya koko kuntsonkothileyo multifactorial iimodeli zokukhula koqoqosho, kaninzi usebenzisa lula, into-mbini, imodeli. Cobb-Douglas - umfuziselo obonisa ukuxhomekeka lwe output (Q) ezi meko ezidale ukuba: Iindleko zabasebenzi - (L) kunye capital investment - (K).

Osoqoqosho Sindulule iinketho ezimbini yokwakha iimodeli factor-mbini, kuthathelwa ingqalelo inkqubela yenzululwazi kunye yobuchule ngaphandle ubhaliso.

Umsebenzi imveliso ye Cobb-Douglas esekelwe NTP

kuqoqosho ethathela ingqalelo kwimpumelelo zokwenene inkqubela yenzululwazi kunye nobugcisa, umsebenzi nekomkhulu nemveliso ngakumbi. Kwiimeko ezinjalo, unako ukufumana iingeniso eziphezulu ngeendleko efanayo ngemigudu kunye nezixhobo zokusebenza. Kulo mzekelo, ezinye iindidi attachments kunceda ukwandisa iindleko nokubonelela yokonga imali ozalayo, ezinye - kukhokelela ekuncipheni-mali. Lokuqala uhlobo lotyalo kukhokelela mali yabasebenzi, kwaye eyesibini - ukugcina eyinkunzi.

Le ndlela akajongi NTP

Kwimeko imodeli yoqoqosho, xa kuthathelwa ingqalelo inkqubela yenzululwazi kunye nobugcisa, ekufumaneni ikapitali kwenzeka phantsi iindleko rhoqo. Osoqoqosho ukufunda zibonisa ukuba ukusetyenziswa kwe ndlela kukhokelela ekuncipheni kwe imveliso yokugqibela.

Kwelinye icala, le meko ukuze kubonakale nemvelo. Kodwa ke eneneni, le meko kukuba kusenokwenzeka ukuba kwelinye icala ebekwe ukufezekisa STP, kwelinye icala kokuba sikhatyiwe ngamashishini, ekubeni akukho inkuthazo olusebenzayo ukuqaliswa ezintsha kwimveliso. Ngenxa yoko, le nkampani ubunzima indleko eyongezelelweyo yokuthenga izixhobo ezitsha nto leyo asetyenziswe kwinkqubo yemveliso, kodwa kuphela oxhonywe umncono nokunciphisa ukusebenza kwayo.

Kulula ukubona ukuba ukuze kubekho izisombululo eliphakathi oludibanisa iindlela ezimbini ezichazwe.

Cobb Douglas model ukuqinisekisa ukukhula

Kuba okokuqala le modeli yaphakanyiswa yi UKnut Wicksell. Kodwa kuphela ngo-1928, oko avavanywa practice, abezoqoqosho Cobb kunye Douglas. Umsebenzi imveliso ye Cobb-Douglas ukuqinisekisa inqanaba iyonke imveliso Q kunye umzamo imali eyinkunzi (L kunye K).

Umsebenzi sijongeka njengoku:

Q = A × Lα × Kβ

Apho: Q - umthamo imveliso;

L - Imizamo;

utyalo Capital - K;

A - factor zobugcisa;

α - ixabiso zabasebenzi iindleko luthambe;

β - mali luthambe ixabiso.

Ngokomzekelo, cinga inxaki Q = L0,78 K0,22. Kulo equation siyakwazi ukubona ukuba imveliso iyonke yesabelo yabasebenzi yi-78% kunye nesabelo nophuculo - 22%.

Imida ye umfuziselo Cobb-Douglas

Umsebenzi imveliso ye Cobb-Douglas icebisa ukulinganiselwa ezithile ekufuneka ithathelwe ingqalelo xa usebenzisa imodeli.

imithamo zemveliso ziyanda, xa omnye wemiba kuhlala ingatshintshanga, kwaye eyesibini inyuswe. Lo ngumongo izithintelo yokuqala neyesibini. Ngaphezu koko, ukuba omnye wemiba Iqinisekile, kunye nezinye kuphuma, iyunithi umda into nganye ezikhulayo yena asebenza ixabiso elidlulileyo.

Xa ixabiso rhoqo esibangela ukwanda yokupasa enye into unobangela zokunciphisa nokunyuka kwexabiso kwimveliso (Q). Le yesithathu kunye nemodeli mqobo yesine Cobb-Douglas.

Iintsilelo yesihlanu yesithandathu zibonisa ukuba nganye kwezi zinto kwimveliso kubalulekile. Oko kukuthi, ukuba omnye wemiba ngu-0, ngokulandelelana, aze kananjalo Q iya kuba zero.
