Suppose the level of output that creates full employment in the ec3is 1800.Using the multiplier of 10, determine the level of investment spending that would create full employment in this economy
When it comes to understanding inflation, and even other aspects of the business cycle, ecological economists will often emphasize the role of energy, and especially oil, in shaping macroeconomic outcomes. To decide how important oil prices are in shaping macroeconomic outcomes such as inflation, do the following: a. Graph the average annual CPI inflation rate from 1970 to the 2000s (www.bls.gov has the data); graph the world price of oil over the same time period (www.eia.doe.gov has these data); overlay the graphs (this is sometimes called “teardrop analysis”) and move them forward and backward a bit to create leads and lags. What kind of a pattern do you see? b. Use the AD/AS model to analyze the impact of an oil shock on the economy. c. What is the necessary consequence of using fiscal policy to stimulate the economy after a supply-side oil shock? What conclusions do you draw from the analysis?
4. Suppose that a typical firm in a perfectly competitive industry has the following total cost curve:
TC = 240 Q "?o 6 Q2 + .08 Q3
a. Is this a short-run cost curve, or a long-run cost curve? How do you know?
b. What will the price of the product be in the long-run?
