higher; lower

A monopolistically competitive firm has a:

refer to the following diagram. demand is relatively elastic:

in the P2 P4 price range.

Advertising can impede economic efficiency when it:

which of the following is characteristic of a monopolist's demand curve?

it is the same as the market demand curve

In the theory of comparative advantage, a good should be produced in that nation where:

its cost is least in terms of alternative goods that might otherwise be produced.

In long-run equilibrium, production for the firm shown in the diagram below is:

less efficient than in a perfectly competitive market.

Refer to the diagrams. for firm B, the elasticity at any price less than $4 is

less than 1 in absolute value

A monopolist's demand curve:

lies above its marginal revenue curve

The more elastic a monopolistic competitor's long-run demand curve, the:

lower its average total cost at its profit maximizing level of output

if average total cost is declining, then

marginal cost must be less than average total cost

The above diagram implies that whenever a firm's demand curve is downward sloping:

marginal revenue is less than price

marginal revenue is positive

may realize a positive economic profit, a zero economic profit, or a loss

monopolistic competition

product variety is likely to be greater in:

monopolistic competition than in perfect competition

The gain from international trade is:

more goods than would be attainable through domestic production alone.

If a nation has a comparative advantage in the production of X, this means the nation:

must give up less of other goods than other nations in producing a unit of X
