which of the following characteristics is not common to monopolistic competition and perfect competition? -firms act to maximize profit -entry barriers into the industry are low -the market demand curve is downward sloping -firms take market prices as given

firms take market prices as given

economies of scale can lead to an oligopolistic market structure because -if larger firms have lower costs, new small entrants will not be able to produce at the low costs achieved by the big established firms -if economies of scale are insignificant, only a few firms are able to produce at the low costs achieved by the big established firms -a few firms can force rivals to produce at low levels of output -a few firms can use high profits to keep out new entrants

if larget firms have lower costs, new small entrants will not be able to produce at the low costs achieved by the big established firms

refer to figure 11-10. suppose that for the past 8 years the firm has been producing Qd units per period using plant size ATC4. now, following a permanent change in demand, it plans to cut production to Qc units. what will happen to its average cost of production? -in the short run, its average cost falls from $47 to $41, and in the long run, average cost falls even further to $37. -in the short run, its average cost rises from $47 to $55, and in the long run, average cost falls to $41 -in the short run, its average cost falls from $47 to $37, and in the long run, average cost rises to $41 -in the short run, the average cost rises from $47 to 455, and in the long run, average cost falls to $37

in the short run, its average cost rises from $47 to $55, and in the long run, average cost falls to $37

the demand for gasoline in the short run is -elastic because people can easily switch to public transportation -perfectly inelastic because people have no choice but to buy gasoline -unit-elastic because people tend to consume a stable amount of gasoline per period -inelastic because there are no good substitutes for gasoline

is less than

if society decides it wants more of one good and all resources are fully utilized, then -it is unable to do this unless technology advances -additional resource supplies will need to be found -it has to give up some of another good and incur some opportunity costs -more unemployment will occur

it has to give up some of another good and incur some opportunity costs

refer to figure 12-1. if the firm is producing 700 units -it is making a profit -it is making a loss -it should cut back its output to maximize profit -it should increase its output to maximize profit

refer to table 4-3. the table above lists the marginal cost of cowboy hats by the Waco kid, a firm that specializes in producing western wear. if the market price of the Waco kid's cowboys hats is $40 -the Waco kid will produce four hats -producer surplus from the first hat is $40 -producer surplus will equal $28 -there will be a surplus; as a result, the price will fall to $24

producer surplus will equal $28

refer to table 4-3. the table above lists the marginal cost of cowboy hats by the Waco kid, a firm that specializes in producing western wear. if the price of cowboy hats increases from $38 to $46 -consumers will buy no cowboy hats -the marginal cost of producing the third hat will increase to $46 -producer surplus will rise from $22 to $46 -there will be a surplus of cowboy hats

which of the following offers the best reason why restaurants are not considered to be perfectly competitive firms? -restaurants do not sell identical products -restaurants compete in small market areas - neighborhoods and cities - rather than in regional or national markets. therefore, restaurants are not small relative to their market size -restaurants usually have entry barriers in the form of zoning restrictions and health regulations -restaurants have significant liability costs that perfectly competitive firms do not have; for example, customers may sue if they suffer from food poisoning

restaurants do not sell identical products

the law of one price states -federal state statutes that prohibit price discrimination -that all customers should pay the same price -that identical products should sell for the same price everywhere -government regulation of prices for all firms

that identical products should sell for the same price everywhere

the total amount of producer surplus in a market is equal to -the difference between quantity supplied and quantity demanded -the area above the market supply curve and below the market price -the area above the market supply curve -the area between the demand curve and the supply curve below the market price

lou buys a star wars: the force awakens poster from evan for $30 and resells it on eBay for $60. which of the following statements is false? -lou has earned some arbitrage profits, assuming that transactions costs are negligible -the transaction has made evan worse off because he undersold the poster -lou has probably incurred some costs in connect with this sale -it is possible that evan has earned some producer surplus from this transaction

the transaction has made evan worse off because he undersold the poster

firms price discriminate -to reduce the quantity sold so as to reduce production costs -to increase profits -to take advantage of customers -to increase total economic surplus

to increase profits

the law of one price holds exactly only if -antitrust laws are being enforced -buyers have complete information -transactions costs are zero -it is impossible for buyers to resell the good

transactions costs are zero

when marginal cost equals average total cost, average total cost is at its highest value

a monopolist's profit maximizing price and output correspond to the point on a graph -where average total cost is minimized -where total costs are the smallest relative to price -where marginal revenue equals marginal cost and charging the price on the market demand curve for that output -where price is as high as possible

where marginal revenue equals marginal cost and charging the price on the market demand curve for that output
