TRUE/FALSE. Write 'T' if the statement is true and 'F' if the statement is false.
125)
Assume that price exceeds average variable cost over the relevant range of demand. If a
monopolistically competitive firm is producing at an output where marginal revenue is $110 and
marginal cost is $118, then to maximize profits the firm should increase its output.

129)
If economies of scale are significant, the typical firm will not reach the minimum point on its

129)
130)
When a monopolistically competitive firm cuts its price to increase its sales it experiences a loss in
revenue due to the income effect and a gain in revenue due to the substitution effect.
130)
131)
An equilibrium in which each player chooses its best strategy given the strategies chosen by the
other players, is called a Nash equilibrium.
131)
132)
A monopolistic competitor does not earn profits in the long run unless it can successfully
differentiate its product in the minds of its consumers.
132)
133)
In monopolistic competition if a firm produces a highly desirable product relative to its
competitors, the firm will be able to raise its price without losing any customers.
133)
134)
A monopolistically competitive industry that earns economic profit in the short run will be able to
expand its market share even if the market size remains constant.
134)

less than the marginal benefit received from the purchase of that unit.
145)
146)
One way firms differentiate their product is to find a market niche.
146)
147)
If marginal revenue is negative then the revenue lost from receiving a lower price on all the units
that could have been sold at the original price is smaller than the additional revenue from selling
one more unit of the good.
