- For an open economy, which of the following expressions represents private saving (S)? Group of answer choices investment plus tax revenues less government expenditure plus net exports, I + TG + NX I+T G NX I + G + NX GT+NXI none of the aboveAggregate expenditure in an open economy equals a) C + I + G + S - M b) C + I + G + T - M c) C + I + G + (X - M) d) C + I + G + (M - X)Consider a small open economy. Assume that GDP (Y) is 5000. Consumption (C) is given by the equation C = 1000 + 0.25(Y-T). Investment (I) is given by the equation I = 1500 – 50r, where r is the real interest rate in percentage points. The world interest rate is actually 5% (r*=5). Taxes (T) are 1000 and government spending (G) is 1500. Net exports are given by the equation NX=500-250Ɛ. Suppose T and G at their initial values (1000 and 1500). Suppose there is a shift in the global supply of funds, so that the new world interest rate becomes 3%. Compute the equilibrium real exchange rate. Represent the equilibrium graphically and interpret your result.
- The following equations describe a small open-economy: C = 10 + 0.5Y I = 160 - 50r NX = 80 - 0.1Y - e e = 50 - 0.1Y + B (r-r*) G= 10 where C is consumption, I is investment, Y is domestic output, r is the domestic real interest rate, NX is net exports, e is the real exchange rate, G is government spending and r* is the foreign real interest rate. (a) Suppose that ß is fairly small, ß = 5, full employment output is Y = 400 and r* = 0.1. What is the equilibrium value of the domestic interest rate, r? (b) Consider instead that ß is fairly large, B = 1000, where again Y = 400 and r* = 0.1. What is the equilibrium value of the domestic interest rate? (c) What happens to r as ß increases? Does r converge to r* as ß approaches infinity? What type of small open economy model does this resemble?Spain operates in the world economy(open economy). Its economy can be described by the following consumption and investment curves: C(r) = 5000-1000r+0.25Y, I(r) = 500-1800r+0.2Y. Its output is Y = 13250 and the government spending is G = 8000. The world Interest rate is 5%. Before joining the world economy, Spain’s closed economy output is 13000. Question: What is Spain’s current account balance?part C and D
- In an open economy, if the level of net exports rises, it must be the case thata) there is an increase in saving.b) there is an increase in investment.c) the value of saving less investment must fall.d) none of the above. Why the correct answer is D?Country A produces GDP according to the following equation: GDP = 5√K or can be read as (5 square root of K), and has a capital stock of 10,000. If the country devotes 25% of its GDP to making investment goods, how much is this country investing? Additionally, if 1% of all capital goods depreciate every year, is the country’s GDP increasing, decreasing or remaining constant?In an economy the National savings is
- Exercise 2 Consider a small open economy. Assume that GDP (Y) is 5000. Consumption (C) is given by the equation C = 1000 + 0.25(Y-T). Investment (1) is given by the equation I = 1500 – 50r, where r is the real interest rate in percentage points. The world interest rate is actually 5% (r*-5). Taxes (T) are 1000 and government spending (G) is 1500. Net exports are given by the equation NX=500-250E. 1. Compute the equilibrium real exchange rate. Is the Purchasing Power Parity assumption respected? Suppose that prices in the home currency are ten times smaller than prices in the dominant foreing currency. Which is the nominal exchange rate? 2. Is the government budget in surplus or deficit? For each of the possible policy tools to achieve a balanced budget, compute the equilibrium exchange rate and represent it graphically. Interpret your results. 3. Suppose T and G at their initial values (1000 and 1500). Suppose there is a shift in the global supply of funds, so that the new world…Question: Which of the following indicates AD in an open economy? a) Private (household) Consumption Expenditure b) Household Investment Expenditure c) Government expenditure + private consumption expenditure d) Household consumption expenditure+ investment expenditure + government expenditure + net exportsUnder a closed system, when net exports equals 0, what must be true about investment spending? A Investment Consumption B Investment = Savings (C) Investment = Government Spending D) Investment Government spending - taxes
