A constant cost, perfectly competitive market is in long-run equilibrium. At present,
there are 1,000 firms each producing 400 units of output. The price of the good is $60.
Now suppose there is a sudden increase in demand for the industry’s product which
causes the price of the good to rise to $64. In the new long-run equilibrium, how will
the average total cost of producing the good compare to what it was before the price of
the good rose?
A) The average total cost will be higher than it was before the price increase since the
increase in demand will drive up input prices.
B) The average total cost will be lower than it was before the price increase because of
economies of scale.
C) The average total cost will be higher than it was before the price increase because of
diseconomies of scale arising from the increased demand.
D) The average total cost will be the same as it was before the price increase.

At the midpoint of the demand curve, in absolute value,
A) the price elasticity coefficient is at a maximum.
B) the price elasticity coefficient is at a minimum.
C) the price elasticity coefficient is zero.
