Toby operates a small deli downtown. The deli industry is monopolistically competitive.
In the long run, Toby will produce where:
marginal revenue equals marginal cost.
price equals minimum average total cost.
price equals marginal cost.
price equals marginal revenue.
Suppose the dry-cleaning market is monopolistically competitive and economically
profitable this year. In the long run, the demand for any one firm’s dry-cleaning services
will _____ as more firms enter the industry, causing economic profits to _____.
decrease; become economic losses
If monopolistically competitive firms are earning positive economic profits in the short
run, then in the long run:
firms will leave the industry.
the demand curves faced by existing firms will move to the right.
economic profits will increase.
economic profits will be reduced to zero.
When a monopolistically competitive firm is making zero economic profits, it is
producing so that the average total cost curve is tangent to the demand curve. At this
output:
the firm is maximizing profits, and marginal cost must equal marginal revenue.
the firm is not maximizing profits, and a slight increase or decrease in output will
lead to positive profits.
since economic profits are zero, the condition that marginal revenue equals
marginal cost is irrelevant.
the condition that marginal revenue equals marginal cost continues to be relevant,
but the marginal revenue and marginal cost curves need not intersect directly below
the point of tangency between the average total cost curve and the demand curve.
Toby operates a small deli downtown. The deli industry is monopolistically competitive.
If some delis leave the industry, Toby’s _____ curve will shift to the _____.
