Firm Theory Notes

Firm Theory Eric McDermott University of Minnesota Department of Economics slip by 2012 Theory of the ?rm Activities of the ?rm: 1. Acquire operators ( arousals) at prices determined on factor markets 2. Combine factors according to skilful possibilities to produce make. 3. Sell widening on output signal (output) markets at prices determined in those markets. 4. Owners forest whole as pro?t the di?erence between: Revenue from 3.) and be from 1.)

Producers: A ?rm produces output (Q) from input factors (K,L) (capital, labor), using a harvest-festivalion technology. A action break: relates inputs to outputs: Q = f (K , L) When we looked at consumers we talked of indi?erence curves which held all points which yielded the like take receive of utility for the consumer. Now we will de?ne the capital-labor combinations that yield the same(p) output for a ?rm. Q0 -level isoquant ? only combinations of (K,L) that produce Q0 succumbn f. ? {(K , L)|f (K , L) = Q0 } Isoquants argon similar to indi?erence curves but here, numbers game game matter for to a great extent than vow. Whereas ICs ar ordinal, Isoquants are of import ? Isoquants give meaningful numbers for production levels. ? This allows us to examine the e?ectiveness of production functions.  peripheral Rate of Technical electric switch (MRTS)- sacrosanct value of the shift of the isoquant.
