Does the law of diminishing marginal utility hold for all goods and services we buy and consume? What are the exceptions?

Assume that there are 2 firms locating in Hotelling’s linear city of length 1. Each firm has a constant marginal cost of c. Consumers are uniformly distributed and have identical preferences represented by U=V-Pi-t(x*-xi)2 . where V-is consumer’s reservation value (consumer surplus from consuming her ideal product at zero price), Pi is the price of firm i’s product, x* is consumer’s location, 0≤x 1 and xi is firm i’s location. a) If both firms are required to locate in the middle, what price would they charge? b) If both firms are required to locate at two different ends of the city what price will they charge?

Discuss the validity of the following statement “Economic models play an important role when it comes to developing sound economic policies.”

Answer the following questions about trading strategies in efficiently inefficient markets.
(a) Discuss how active investors can be compensated for their information collection. Give examples of how you could try to collect information about specific firms and how you could trade on this.
(b) You work as an analyst at a hedge fund. Your manager suggests an investment strategy involving mergers and acquisitions (M&A). He provides anecdotes that suggest that the stock price of the target firm seems to go up once the deal is successful. He suggests a trading strategy that involves buying such firms right after the merger announcement, but before the actual merger. Should the hedge fund follow this trading strategy and, if so, what are the risks?
(c) Your manager also notes that the price of the target firm jumps right after the merger announcement. Suggest a trading strategy that might allow the hedge fund to profit from this occurence.

(3) The money supply is fixed at $60billion and the equilibrium value of money 1/P = 1/2. The Federal Reserve increases the money supply by $20 billion and as a result the new equilibrium price level is 5. Use the Money Supply-Demand Model (Diagram) to explain clearly how equilibrium is restored in the model. If money supply increases the value of money will not increase but will go down.
