- Based on your comparison of the two economies, would you expect the multiplier in an economy to vary over its business cycle? (10 marks)
- Some economists estimated the size of the multiplier in the Great Depression to be equal to 1.8. Explain how the following characteristics of the US economy during the Great Depression could have affected its value: (10 marks)

- Explain why a positive bargaining gap arises. (7.5 marks)
- Assume the positive bargaining gap is 1%. Draw a diagram with years on the horizontal axis and the price level on the vertical axis. Starting from a price index of 100, sketch the price level’s path for the 5 years that follow, assuming the bargaining gap remains at 1%. (15 marks)
- Who are the winners and losers in this economy? (7.5 marks)

- Provide an example of circumstances under which households distinguish between base and bank money. (10 marks)
- Suppose the central bank wishes to restrict the level of economic activity in the economy because it is afraid that inflation will increase. How does it implement its decision? What role do households, firms and banks in the home country and abroad play in this process? (10 marks)

- Assume that the central bank has an inflation target of 2% per year, but inflation is currently running at 4%. The nominal policy (interest) rate is currently 5%. The central bank needs to create a negative bargaining gap and estimates that the real policy rate required to achieve this is 3%. What would be the targeted nominal policy rate? (10 marks)
- Why the unemployment rate does not shrink continuously in a world with continuous technological progress.? (10 marks)
