In the spot market, one silvo buys two freedos. If interest rate parity holds, how many freedos can we expect to buy with one silvo 12 months from today? The 12-month futures contract for silvos is trading at US$0.7700; the same contract on freedos is trading at US$0.3500. If you cover a currency carry trade position with futures, is there an opportunity to profit? If so, exclusive of leverage and transactions costs, what is your annual rate of return? Page 6 of 9
#2 You are given the following information about an economy: 1) at full employment, the unemployment rate is 5.5% and real output is $900 billion; and 2) the following table applies: State: 1 2 3 Inflation rate: 5% 2.5% 1% Unemployment rate: 3% 5.5% 8% Real output: $930 billion $900 billion $850 billion Assuming the price level in Period 0 was 150, graphically show the economy s long-run and short-run Phillips Curve and corresponding long-run and short-run aggregate supply curves in Period 1.

Bonus Question 10 points Write a short essay contrasting the types of fiscal policy you would recommend in each of the following situations: 1. The economy appears to be on the precipice of a deep recession and policy makers need to boost aggregate demand quickly and at the least cost. 2.
