Question

Giuseppe’s Pizza is a family-owned pizzeria. It uses 4 pizza ovens and hires labor to make and sell pizza. Giuseppe’s cost of capital is $128 per over per day and its cost of labor is $64 per worker-day. The pizzeria’s production function is:

q = 20K0.5L0.5

where q is the number of pizzas produced per day, K is the number of ovens used, and L is the number of workers employed.

(a) Find Giuseppe’s short-run production function.

(b) If Giuseppe’s employs 6 workers, what is the pizzeria’s average fixed cost?

(c) If Giuseppe’s produces 80 pizzas per day, what is the firm’s short-run average total cost?

(d) If Giuseppe’s produces 80 pizzas per day, what is the firm’s short-run average variable cost?

(e) What is Giuseppe’s short-run marginal cost of producing the 81st pizza?

Explanation / Answer

(a)q = 20K0.5L0.5

q=20(4)0.5L0.5

q=40L0.5

(b)FC=(128*4)=516

AFC=516/6=86

(c)q=40L0.5

80/40=L0.5

L=4

TC=VC+FC

=(64*4)+(512)

=256+512=768

ATC=768/4=192

(d) AVC=256/4=64
