ECON101 Lecture Notes - Lecture 25: Repeated Game, Demand Curve, Oligopoly

Document Summary

The demand curve is kinked at the current price and quantity. The firm assumes that if it raises its price, no price will change the price. The firm assumes that if it lowers the price, other firms will lower their price. Marginal revenue (mr) is discontinuous at the current price +quantity. The dominant firm model: game theory models. W xd = d - s: all games share some common features, rules, strategies, payoffs, outcome. Two strategies- confess to crime or deny to crime. Possible outcomes- there"s 4: both deny, both confess, art confesses and bob denies, bob confesses and art denies. No matter what art does, the best strategy for bob is to confess. The dominant strategy: no matter what bob is doing, the best option strategy for art is to confess. Nash equilibrium: both players should confess to this crime and end up getting 3 years in prison. Chapter 6: government intervention in the market economy: perfect competition.

1. Patent laws:
reduce incentive to innovate by restricting market entry
reduce incentive to innovate by making it difficult to use thepatented innovation
increase incentive to innovate by restricting entry into amarket
increase incentive to innovate by giving a firm permanent andexclusive production rights

2. Which of the following is true of marginal revenue for amonopolist that charges a single price?
P = MR because there are no close substitutes for the monopolist'sproduct.
P > MR because the monopolist must decrease price on all unitssold in order to sell an additional unit.
P < MR because the monopolist must decrease price on all unitssold in order to sell an additional unit.
AR = MR because there are no close substitutes for the monopolist'sproduct.

3. Negative marginal revenue means that
total revenue is decreasing as output increases
the firm is maximizing its total revenue
the firm is maximizing its economic profit
total revenue is increasing at a decreasing rate as outputincreases

4. A profit-maximizing monopolist produces an output level atwhich
marginal revenue is the greatest distance from marginal cost
price is less than marginal cost
the value to society of the last unit produced equals marginalcost
marginal revenue equals marginal cost

5. Compared to a perfectly competitive market, a monopoly tends toproduce
more output and charge a higher price
the same amount of output, but charge a higher price
less output and charge a higher price
less output and charge the same price

6. Monopolistic competition is best described as
many firms with some control over price, and some productdifferentiation
many firms with no control over price, producing identicalproducts
a few firms with some control over price, producing highlydifferentiated products
a few firms with no control over price, producing similarproducts

7. Which of the following characteristics does perfect competitionshare with monopolistic competition?
price-taking firms
zero long-run economic profit
homogeneous product
some barriers to entry

8. Monopolistically competitive firms do not achieve productiveefficiency because
entry of firms raises production costs in the long run
barriers to entry allow profit to be earned in the long run
price is greater than marginal cost at the profit maximizing outputlevel
profit is maximized at a quantity where average total cost is notminimized

9. There are multiple models of pricing behavior in oligopolisticmarkets because
it is difficult to predict how rival firms will react to anypricing decision
the demand curve slopes upward for these firms
firms could earn profit in the long run unlike other markets
price has a direct impact on profit for a firm in oligopoly

10. Which of the following is likely to occur when a two-persongame can be played repeatedly?
Collusion and cooperation among the players
The prisoner's dilemma
The industry demand curve will become perfectly elastic
The industry demand curve will become perfectly inelastic
