Chapter_4___Estimating_Demand

Multiple Choice

- Using a sample of 100 consumers, a double-log regression model was used to estimate demand for gasoline. Standard errors of the coefficients appear in the parentheses below the coefficients.

Ln Q = 2.45 -0.67 Ln P + . 45 Ln Y – .34 Ln Pcars

(.20) (.10) (.25)

Where Q is gallons demanded, P is price per gallon, Y is disposable income, and Pcars is a price index for cars. Based on this information, which is NOT correct?

- Gasoline is inelastic.
- Gasoline is a normal good.
- Cars and gasoline appear to be mild complements.

- When airlines post prices on an electronic bulletin board at 8:00 a.m. each morning, the decision-makers are engaged in
- a single play game
- a sequential game
- an entry decision
- a simultaneous game
- an infinite repetition game

- The starting point of many methods for predicting equilibrium strategy in sequential games is
- designing proactive reactions to rival actions
- information sets
- uncertain outcomes
- backwards induction based on an explicit order of play
- endgame analysis

- Consider the game known as the Prisoner’s Dilemma. What’s the dilemma?
- By both not confessing, both get to the cooperative solution and minimize time in prison.
- By both confessing, both get to the noncooperative solution and both serve significant time in prison.
- As a group, they are better off cooperating by not confessing, but each player has an incentive to be first to confess in a double cross.
- The problem is that the spies should never have been caught; they should move to Rio.

- When there is an Equilibrium (or a Nash Equilibrium), we expect that:
- once the firms get there, no one will change their strategy.
- firms will tend to select a randomized strategy.
- neither firm will care what it does.
- this is always a dominated strategy.

- The Prisoner’s Dilemma involves two spies who are held in separate soundproof rooms. But even if the two spies could communicate, what makes it difficult for them to achieve the cooperative solution (both not confessing)?
- The problem is their lack of information.
- The problem is that it is a nonzero sum game.
- The problem is that both spies have incentives to double cross each other.
- The problem is that all the outcomes are not particularly good for either player.

- When there is no Equilibrium (or no Nash Equilibrium), we expect that:
- the firms end up in the cooperative strategy.
- a firm will follow a randomized strategy.
- a firm will not care what it does.
- a firm will very likely have a dominant strategy.

- In a game, a dominated strategy is one where:

- It is always the worst strategy
- It is the strategy that is the best among the group of worst possible strategies.
- Is sometimes the best and sometimes the worst strategy

- If two firms operate in a market that is characterized as being a Prisoner’s Dilemma, and the two strategies given them are to restrict output or expand output, which of the following strategy pairs would represent the cooperative solution in a duopoly for firm 1 and firm 2, and firm 1 given first in each pair?
- {expand output, restrict output}
- {restrict output, expand output}
- {restrict output, restrict output}
- {expand output, expand output}

- A key to analyzing subgame perfect equilibrium strategy in sequential games is
- predictable behavior

- establishing a bond forfeited by violating the commitment
- investing in a non-redeployable reputational asset tied to the promise or threat
- interrupting the communication of negotiated compromises
- offering a warranty
- delivering a hostage (e.g., a patent license triggered by violating the promise)

- The difference between cooperative and non-cooperative games is
- cooperative games allow side payments to support collusion
- non-cooperative games encourage communication of sensitive information between arms-length competitors
- cooperative games involve randomized behavior
- cooperative games necessitate an explicit order of play
- inconsequential except when players have contractual relationships

- An illustration of a non-credible commitment is the promise
- to not increase capacity in a declining industry
- to match a new entrant’s discount price
- to enter a profitable industry
- to restrain output to the quota assigned by a cartel
- to exit in the face of projected losses.

- A dominant strategy differs from a Nash equilibrium strategy in that
- Nash equilibrium strategy does not assume best reply responses
- dominant strategy assumes best reply responses
- only Nash strategy applies to simultaneous games
- one dominant strategy is sufficient to predict behavior in a multi-person game
- Nash strategy is often unique

- In adopting mixed Nash equilibrium strategy, a player is attempting to
- randomize his or her own behavior
- make the opponent favor a course of action preferred by the first player
- randomize the outcome of actions

- none of the above

- To trust a potential cooperator until the first defection and then never cooperate thereafter is
- a dominant strategy
- an irrational strategy
- a grim trigger strategy

- a subgame imperfect strategy

- Non-cooperative sequential games can incorporate all the following features except
- a single decision-maker in the endgame
- no communication
- finite or infinite time periods
- third-party enforceable agreements
- an explicit order of play

- If one-time gains from defection are always less than the discounted present value of an infinite time stream of cooperative payoffs at some given discount rate, the decision-makers have escaped

- the hostage is more valuable than any given exchange
- the hostage is difficult to replace

- In deciding whether to invest in excess capacity in order to deter entry, incumbents should consider all of the following except
- the order of play in pricing and capacity choice decisions
- the customer sorting pattern
- the sunk cost required to achieve excess capacity
- the joint-profit-maximizing cartel output
- the potential entrant’s projected profitability

- An inverse intensity customer sorting rule is one in which
- customers with high willingness to pay secure the discounted goods
- customers are rationed randomly between the discounted and full price goods

- The capital structure of Wildcat Wells, an independent petroleum exploration and drilling company, consists of 40 percent debt and 60 percent equity capital. Debt capital consists of a bond (which matures in 10 years) issued five years ago at an interest rate of 10 percent. Since then market interest rates have risen substantially. The firm has been advised by its investment banker that additional debt financing (bonds) could be obtained at a rate of 12 percent. In the last six years of operations, Wildcat Wells has averaged a 12 percent compound rate of growth in earnings and dividends. This rate is expected to continue for the foreseeable future. Next year’s dividend is projected to be $.75 per share. The firm’s stock is currently selling for $25 per share. Wildcat Wells has a 40 percent marginal income tax rate.

(a) What is the firm’s after-tax cost of debt financing?

- The Ministry of Recreation has decided to consider a proposal to build a new regional park. A piece of land is available which can be purchased, after condemnation proceedings, for $1,000,000. A private developer has offered the owner of the land $2 million. The value of direct recreational benefits from the park is estimated at $175,000 per year for 25 years. In addition, indirect benefits of $12,500 per year for 25 years have been projected. Increased values in land surrounding the project will provide immediate, one-time pecuniary benefits to the land-owners of $1,000,000.

The direct cost to operate and maintain the park is estimated at $50,000 per year. The Ministry believes a 10% discount rate is appropriate to evaluate projects of this sort. Should the park be built? Justify your answer using cost benefit analysis.
