A) If the marginal propensity to consume is 0.8, explain what the long-run effects would be on real GDP, public saving, and national saving.

Use the appropriate graphs to illustrate and state what the reduction in Social Security benefits would do to each of the following in the long run: national saving, investment, the US real interest rate, net capital outflows, the real exchange rate, and the trade deficit.
C) Now, consider the small open economy of Norway, which has a trade surplus. If the US, a large open economy, were to reduce its Social Security benefits, use the appropriate graphs to illustrate and state what would happen in the long run to Norway’s national saving, investment, interest rate, real exchange rate, and trade surplus.
