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. Illustrate how the Fed's choice of large it makes reveals its trade off between inflation and output in the short run.arrow_forward

This is constant and equal to the average cost of television sets. The annual demand for television sets is given by the following equation: Q = 200,000-500P, where Qis the quantity sold per year and P is the price of television sets. a) If television sets are sold in a perfectly competitive market, calculate the annual number sold. Under what circumstances will the market equilibrium be efficient? b) Show the losses in well-being each year that would result from a law limiting sales of television sets to 100,000 per year.
