Answer to Question #108609 in Microeconomics for mark

Question

Consider the model of a market with four identical producers. Each producer has the same constant average variable cost. The aggregate demand for the product these firms produce is Y=1000.p-5. The producers choose their quantities simultaneously and the price is the highest price p at which the total quantity can be sold. The price at the equilibrium of this model is 20. What is the value of the firms’ constant average variable cost?

Answer 1

$Y'=-5×\frac {1000}{p^6};$

$Y'=\frac {-5000}{p6};$

$Y'=\frac {-5000}{20^6};$

$-5000×4=-20000;$
