1. Modeling Questions – Cost Functions and Profit Maximization

A perfect competitive firm’s short-run cost function is estimated to be

Cy=10+18 y-4y2+0.6y3 ,

where y is the output, C(y) is the total cost.

a.(2’) What is the firm’s short-run fixed cost?

b.(2’) What is the firm’s short-run variable cost function?

                              

c.(12’) Derive the functions of MC, AVC, AFC, and AC.

   

d Carefully graph your functions in the following combinations:

TC, FC, and VC vs. y on a single graph.

AC, AFC, AVC, and MC vs. y on a single graph.

(4’) On the graph (ii) at the bottom, label clearly the minimum AVC point and explain why MC curve crosses AVC curve at its minimum.

Suppose that a firm’s short-run total cost function is STC= 0.1q2 + 4q +100. Will the producer surplus at P=$15 be $302.5? Suppose that a firm is price taker. If the price is equal to marginal cost, then the profit is being maximized. If a firm wished to maximize profit, it will always reduce output if wage rates rise. If a competitive firm's price is below its marginal cost, an increase in production will usually decrease profits. A profit‑maximizing firm...
