Game theory
100

What is the only decision that a perfectly competitive firm has to make?

What quantity to produce

100

What demand curve is perceived by the monopolist?

the entire market demand (monopoly=market)

100

What characterizes monopolistic competition ?

Many sellers selling similar but differentiated products

100

What are the five necessary components of a game?

Players, actions, strategies, outcomes, payoffs

200

A perfectly competitive firm perceives a demand curve that is __________ ?

perfectly elastic

200

When a monopolist identifies its profit-maximizing quantity of output, how does it decide what price to charge?

By identifying the value of the demand curve at that quantity (ie follow the line up to the demand curve)
200

How can a monopolistic competitor tell whether the price it is charging will cause the firm to earn profits or experience losses?

Compare the price they are charging to their average total cost at that quantity

200

The cartel game (cooperate, cheat) is an application of which classic 2x2 game?

                      cooperate           cheat

cooperate       $1K, $1K            $200,$1.5K

cheat              $1.5K,$200        $400,$400

Prisoners' dilemma

300

What are the three conditions that allow for a perfectly competitive market to form?

Identical product, many firms, no barriers to entry

300

The shut-down point is the intersection of what two curves?

MC and AVC

300

How is the perceived demand curve for a monopolistically competitive firm different from the perceived demand curve for a monopoly or a perfectly competitive firm?

it is something between perfectly elastic and market demand

300

What is the Nash equilibrium in the stag hunt game shown below?

              stag        hare       

stag       10,10        1,8

hare       8,1           5,5

There are two NE, stag-stag and hare-hare

400

What happens in a perfectly competitive market if short term profits are >0?

Firms will enter and drive down profits

400

What is predatory pricing?

When a firm with market power aggressively cuts prices to block/discourage competition

400

Aside from advertising, how can monopolistically competitive firms increase demand for their products?

Product differentiation

Suppose the prisoner's dilemma was a repeated game, that was played between the two prisoners 5 times. What will be the outcome of the five games?

silent, silent, silent, silent, confess

500

Your company operates in a perfectly competitive market. You have been told that advertising can help you increase your sales in the short run. Would you create an aggressive advertising campaign for your product? Explain

No - if you are operating in a perfectly competitive market you will be spending money advertising without any improvement in outcome (because you face a perfectly elastic demand curve). You also likely do not have money for an advertising campaign because you are earning 0 profits under perfect competition.

Imagine a monopolist could charge a different price to every customer based on how much the customer is willing to pay. How would this affect deadweight loss? (be precise)

Deadweight loss = 0

500

Make a case for why monopolistically competitive industries never reach long-run equilibrium.

Positive profits will encourage entry, this will drive down prices, with lower prices it will not be feasible for firms to invest in product differentiation, and there will be a tendency to exit the market... this will create a cycle

500

Find the Nash equilibrium of the following game:

           X           Y            Z

A        6,6        8,20        0,8

B       10,0       5,5          2,8

C        8,0        20,0        4,4
