2. a) Consider a market where one firm (firm 1) currently produces, but a second firm (firm 2) is intending to enter and sell an identical product. The market has inverse demand given by p = 40 – Q, where Q is the total output sold in the market. Firm 1 has a marginal cost of 16 and firm 2 has a marginal cost of c < 16, with no fixed cost for either firm. Firm 2 has a choice of competing on price or quantity, with firms making their choices simultaneously (i.e. the market will be either a Bertrand or Cournot duopoly). If you were advising firm 2 on entering this market, how would you advise it to compete? To what extent would the size of firm 2’s cost advantage affect your advice?
b) Now assume that firm 2 is aware that other firms are considering entering the market, so the market may over time change from a duopoly to an oligopoly with more than two firms. This would not change the nature of competition (i.e. any additional firms would set price or quantity in line with the first…
1. Consider two firms (i=1,2) interacting in the market. Assume that firms compete in
quantities and therefore they choose either to cooperate or not in each round. If a firm
deviates it earns monopoly profit for a round and a punishment phase will follow from next
round onwards (for ever) where both firms choose the Cournot quantity. Assume a
discounting factor & and that firms meet in the market in every period. The demand facing
the industry is p = 1 92. Let Q = q1 + 92 denote the aggregate industry output

level. Assume further that production is costless.
Q4 (30 points)
Subsidy in Auctions
Consider a sealed-bid second-price auction with two bidders. Valuation of bidder 1 is drawn
from the uniform distribution on [0, 100], and valuation of bidder 2 is independently drawn
from the uniform distribution on [0, 300].

- Question Seven There are specific applications of the hidden-action or moral hazard model. Consider employment contracts signed between a firm's owners and a manager who runs the firm on behalf of the owners. The manager is offered an employment contract which they can accept and decide how much effort, e ≥ 0, to exert. Suppose that an increase in effort, e, increases the firm's gross profit, not including payments to the manager, but is personally costly to the manager and the firm's gross profit, Пg, takes the following form: Пg = e +ε, ε~N(0,2). Let s denote the salary, which may depend on effort and/or gross profit, depending on what the owner can observe, offered as part of the contract between the owner and manager. Suppose that the manager is risk averse and has a utility function with respect to salary of the form: Aσ² U(W)=μ- 2 a) Derive the optimal result of the owner's expected net profit where there is full information and state what it implies. b) Suppose now that the…arrow_forward1. The IS/MP model assumes that the Fed sets the real interest rate at a given level Rt. Suppose the Fed adopts a monetary policy rule that instructs it how to change the real interest rate in response to short-run output. Let's call this a monetary policy rule (MPR): The parameter x is positive. Rt=+xY a) Redraw the IS/MP diagram replacing the MP curve with the MPR curve. Show how an aggregate demand shock affects output and interest rates in the short run. Use the IS and MPR equations to solve for the changes in output and the real interest rate. b) How does the change in a affect investment in the IS/MPR model? Explain how a tax cut affects short-run output and investment in this version of the short-run model. The effect on investment is called crowding out. c) Add the Phillips curve to complete the short-run model.
