Let K denote the quantity of capital a country has at the beginning of period t. Also, suppose that capital depreciates at a constant rate d, so that dK; of the capital stock wears out during period t. If investment during period t isdenoted by It, and the country does not trade with the rest of the world (the current account surplus is always zero), then we can say that the quantity of capital at the beginning of period t + 1 is given by K+1 = (1– d)K; +It | Suppose at the beginning of year 0 that this country has 80 units of capital. Investment expenditures are 10 units in each of years 0, 1, 2, 3, 4, ..., 10. The capital stock depreciates by 10% per year. (a) Calculate the quantity of capital at the beginning of years 0, 1, 2, 3, 4, ..., 10.

For a small open economy, the domestic real interest rate (r) for a given country must be the same as the world real interest rate (r). only if capital is not perfectly mobile because with no barriers to capital flows, if the world rate > domestic rate the domestic residents would just lend abroad putting upward pressures on the domestic rate until both rates equal each other because with no barriers to capital flows, if the world rate < the domestic rate domestic residents would only lend to foreigners putting downward pressures on the domestic rate until both rates equal each other for none of these reasons for all of these reasons

Domestic economy: Consider two open economies in which the real exchange rate is fixed and equal to one. Consumption, investment, government spending, taxes, imports and exports are given by equations on the right for each economy. Variables with "*" denote values for the foreign economy. C = 11 + 0.7 (Y- T) | = 12 Solve for equilibrium output in the domestic economy Y, and foreign economy Y". (Enter your answer as a whole number.) G = 10 T= 9 Y= 89. IM = 0.3Y Y* = 89. EX = 0.3Y* What is the multiplier for each country? Foreign economy: (For the following numerical responses, round your answer to one decimal place.) C* = 11 + 0.7 (Y*- T") The multiplier for the domestic country is * = 12 The multiplier for the foreign country is G* = 10 T* = 9 IM* = 0.3Y* EX* = 0.3Y .....
2) On the graph below show how the Solow model will differ if we allow for trade. Assume that the country has a current account deficit. Hint: Remember that national savings is equal to sY+ = It + CA₁₁ where CA, is the nation's current account at time t. Therefore, the (per worker) capital accumulation function will become k++1 - k₁ = syt - cat - (n+ d) k₁, where ca, is the "current account per worker."
