Macroeconomic Questions

I have to complete the following questions where each question must consist of at least half a page. Which is why I’ve selected five pages to ensure this is properly completed. The four questions that must be answered in this essay are the following: 1) What is not included in the measure of national GDP? Suggest how we could included them in the future. 2) If the US dollar drops in value against the Japanese Yen, what would happen to the volume of exports from USA to Japan? Why? 3)Give an example of a “leading Indicator” and explain how it can predict how the general economy will behave. 4) Discuss the role of the Federal Reserve in getting an economy out of a recession by eliminating the Recessionary GAP. Be specific, what are the tools and how are they used?
