question
Monopolistically competitive firms
answer
*not productively efficient in the long run
*produce where MR=MC
*charge consumers on demand curve on MR=MC output
*different from other companies in industry
*demand curve is downwards sloping
*some control over price
*easy market entry and exit
*close substitutes
*the closer the substitutes the more elastic the demand curve
*consumers are responsive to price changes

question
Long-run equilibrium
answer
*firm realizes normal profits
*removes incentives for firms to enter or exit market
*removes incentives for firms to enter or exit market
question
Oligopoly barriers
answer
*pricing strategy
*patents
*significant cost of capital
*economies of scale that may allow only a small number of firms to operate in a market
*control of the resources needed to produce output

question
Oligopolistic firms rely on decisions of other firms, deeming oligopoly firms
answer
mutually interdependent
question
Oligopoly
answer
*producers who behave strategically when making decisions related to the features, prices and advertising of their products
*a few large producers, producers are price makers
*extensive entry barriers
*either standardized or differentiated products
*a few large producers, producers are price makers
*extensive entry barriers
*either standardized or differentiated products
question
Nash equilibrium
answer
an outcome in which, unless the players can collude, neither player has an incentive to change strategy
question
Collusion
answer
situation in which individuals, firms, or any group of actors coordinate their actions to achieve a desired outcome
question
Prisoner's dilemma
answer
each player will peruse a dominant strategy and, as a result, be worse off than if they had not
question
Dominant Strategy
answer
situation in which a particular strategy yields the highest payoff, regardless of the other player's strategy
question
Profit
answer
*price
*quantity of output
*average total cost
*quantity of output
*average total cost
question
Economic profit creates
answer
incentives for firms to enter a market
question
Perfect competition
answer
*easy entry and exit
*producers are price takers (no control over prices)
*standardized product
*large number of buyers and sellers
*producers are price takers (no control over prices)
*standardized product
*large number of buyers and sellers
question
Mutual interdependence
answer
*situation in which the strategy followed by one producer will likely affect the profits behavior of another producer.
*studied using game theory
*studied using game theory
question
Game Theory
answer
used to study and analyze oligopoly strategies
question
Productive efficiency
answer
produce output at lowest possible total cost per unit of production
question
Allocative efficiency
answer
producing goods and services that consumers most want where MB=MC
question
Product differentiation
answer
strategy of distinguishing one firm's product from the competing products of other firms
question
Graph:

question
Graph:

economic profit
answer
when MR is above minimum ATC on the demand curve
question
Graph:
loss
loss
answer
when MR is below minimum ATC on demand curve
question
Graph: profit per unit
answer
MR=MC on demand - ATC
question
Profit per unit
answer
(Price-ATC). ATC=AFC+AVC; AFC=TFC/Q
question
Total Profit
answer
(Price-ATC) x Q.
ATC=AFC+AVC;
AFC=TFC/Q
ATC=AFC+AVC;
AFC=TFC/Q
question
Economic profit
answer
TR minus explicit and implicit cost of production
