Expert Solution

Q1
Answer
option D

the perfectly competitive firm produces at P=min(ATC)=long run marginal cost
Q2

In the long run in a perfectly competitive industry, price equals marginal cost and firms earn no economic profits. The following two equations describe this long-run situation for prices and costs, where the numbers indicate the amounts of each input (labor and land) needed to produce a unit of each product (wheat and cloth): P wheat = 60w + 40r P cloth = 75w + 25r If the price of wheat is initially 100 and the price of cloth is...
