Problem: Assume that you have the following open economy where C = 10 + 0.8(Y-T); I = 10; G = 10; T = 10 and imports and exports are given by IM = 0.3Y and X = 0.3Y* respectively where Y* is foreign output.
Then solve for the equilibrium output in the domestic economy given Y*. What is the multiplier effect for this open economy? What happens to Y and the trade balance over time if Y*'s economy grows faster than Y's economy. Assume the domestic government has a target level of output of 125 and the foreign country does not change G*, what increase in G is necessary to achieve the target output in the domestic economy? What would be the increase in G and T needed if the government wanted to keep a balanced budget?
