Suppose the wheat growing industry in the US is perfectly competitive and there is free entry in the long run. the market demand function is Qd= 580 -4p, which is measured in tons per month. each producer in the industry has a fixed cost of $400 and a variable cost function given by VC=q^2 +5q, where q is the output of an individual producer.
a)calculate the long run market equilibrium price and quantity. How many firms are there in the economy?
Suppose the marginal cost increases by 2$ from the long run equilibrium. At the same time the market demand decreases by 34. Answer the following:
b) calculate the new short run market equilibrium price and quantity
c) what is the profit of each individual firm in the short run?
d) Draw a graph to show the short run and long run response of the economy. Mark the short run and long run equilibrium price and quantity on the graph.
