what is marginal cost?
the sum of total variable cost and total fixed cost
what is total cost?
demand curve shifts leftward
when new firms enter a monopolistically competitive industry, each existing firm's

why do economists say that monopoly is "inefficient"?
a monopoly limits its output and charges a higher price for its product
how do monopoly outcomes differ from competitive outcomes?
price equals marginal cost for the last unit it sells
if a monopolist can perfectly price discriminate, then
total revenue increases when price decreases
if a monopoly is operating along the portion of its demand curve where marginal revenue is positive, its

in the short-run, a competitive firm decides
P>ATC
in the short-run, a perfectly competitive firm will earn an economic profit as long as
lesser; higher
a single-price monopolist produces a _____ quantity than a perfectly competitive industry and charges a _____ price than the perfectly competitive industry
the economic profit for each firm equals zero
(2) in the long-run equilibrium in the perfectly competitive market
a natural or legal impediment that makes it difficult for new firms to enter a market
a barrier to entry is
MR = MC
a firm in a monopolistic competition produces where
product differentiation
a firm in monopolistic competition can determine what price to charge for its product because of

profit
a firm's basic goal is to maximize its

a monopolist
an industry in which one firm can supply the entire market at a lower price than two or more firms
a natural monopoly is defined as
MR = MC
a perfectly competitive firm maximizes profit when
short run
a period of time in which the quantity of at least one factor of production used by a firm is fixed is called the
it creates a deadweight loss since P> MC
a single-price monopolist is inefficient because
MR = MC
a single-price monopolist maximizes profits by producing the output at which
total revenue that exceeds the opportunity cost
an economic profit for a self-employed entrepreneur is
there are many firms in it, each selling an identical product
an industry is perfectly competitive if
product differentiation
brand name drugs are chemically identical to their generic counterparts. Yet, consumers often prefer the brand name product to the generic product. Making consumers think that a brand name drug differs from its generic counterpart is an example of

one benefit of monopolistic competition over perfect competition is
explicit costs plus implicit costs
opportunity cost equals
converts all consumer surplus into economic profit

different customers even though the cost of selling to each is the same
price determination is the practice of charging different prices to
monopolistic competition
small pizza parlors exist in just about every town. Anyone can open a pizza parlor, and the pizzas from one parlor typically have different tastes and sizes than pizzas from another parlor. Thus, the pizza industry is an example of
