1. In 1982 Mexico was the first Latin American country that declared its bankruptcy. Argentina, Brazil and the rest of the Latin American countries followed. The average rate of inflation during the 80´s reached the 65.2% for Mexico, 724.6% for Argentina, and 613.8% for Brazil. Explain how the Government can contribute to this situation and explain the economic consequences and costs of a high inflation rate (hyperinflation).

2. Let's assume that the economy suffers from unemployment. How can monetary policy help to combat it? Explain. Use the real money balances market, the IS-LM function, and the Cobb-Douglas production function. Will this policy have any effect on prices?

What is going to happen with the money supply in the EU-zone? Explain how it works and use all the markets involved. Including IS-LM. Why do you think the ECB took that decision? Explain

4. Let's suppose that b coefficient in the investment function is small. Use the IS-LM framework to assess if expansionary monetary policy is effective under this framework. Explain. Hint: if b is small that will have an effect on the slope of the IS function.

5. Let's assume the country suffers from a liquidity trap (people prefer to hold cash than any other asset). Then the central bank of this economy decides to expand money supply. How effective is this policy? Explain and use the IS-LM functions. What about expansionary fiscal policy? Will it be effective in achieving its goal? Explain and use the graphs.
