Sequential games are used to analyze firms that are subject to the prisoner's dilemma. situations in which one firm acts and other firms respond. second-price auctions. cartels.

situations in which one firm acts and other firms respond.

In the long run, a perfectly competitive market will supply whatever amount consumers will buy at a price which earns the market an economic profit. generate a long-run equilibrium where the typical firm operates at a loss. supply whatever amount consumers demand at a price determined by the minimum point on the typical firm's average total cost curve. produce only the quantity of output that yields a long-run profit for the typical firm.

supply whatever amount consumers demand at a price determined by the minimum point on the typical firm's average total cost curve.

A major difference between monopolistic competition and perfect competition is the degree by which the market demand curves slope downwards. the barriers to entry in the two markets. that products are not standardized in monopolistic competition unlike in perfect competition. the number of sellers in the markets.

The prisoner's dilemma illustrates why firms will not cooperate if they behave strategically. why firms have an incentive to cheat on agreements. how cooperation in strategic situations lead to the economically efficient market outcome. how oligopolists engage in implicit collusion under strategic situations.

why firms will not cooperate if they behave strategically.

If a firm shuts down it will produce nothing but must pay its fixed and variable costs. will earn enough revenue to cover its variable costs but not all of its fixed costs will suffer a loss equal to its fixed costs. will produce nothing but must pay its variable costs.
