- The open economy multiplier is calculated as follows: A. 1/[1minus−(marginal propensity to consume + marginal propensity to invest)] B. 1/[1minus−(marginal propensity to consume + marginal propensity to import)] C. 1/[1minus−(marginal propensity to consume + marginal propensity to invest + marginal propensity to import)] D. 1/[1minus−(marginal propensity to consume + marginal propensity to invest minus− marginal propensity to import)arrow_forwardPolicymakers in open economies face a “trilemma” of three conditions that cannot all be realized at the same time. Which one of the following is not part of this “trilemma” of open-economy macroeconomics? Multiple Choice Be open to international flows. Implement capital controls. Fix its exchange rate. Control its domestic interest rate.arrow_forwardGiven the following variables in the open economy aggregate expenditure model, autonomous consumption (C0) = 200, autonomous investment (I0) = 200, government spending (G0) = 100, export spending (X0) = 100, autonomous import spending (M0) = 100, taxes (TP) = 0, marginal propensity to consume (c1) = 0.8, marginal propensity to invest (i1) = 0.1, and marginal propensity to import (m1) = 0.15, a. Calculate the equilibrium level of income for the open economy aggregate expenditure model. b. Determine the value of the open economy expenditure multiplier. c. If there is an increase in autonomous import expenditure from 100 to 200 resulting from an increase in the currency exchange rate, calculate the new equilibrium level of income and the value of the multiplier. d. Compared with the original equilibrium in part a, if the government decides to impose taxes (TP) of 100, calculate the new equilibrium level of income. e. Find the value of the multiplier and the corresponding equilibrium…arrow_forward
- The equilibrium condition for GDP in an open economy is: Y = C + I + G + (X – M) GDP can be eitherspent, saved, or taxed away , so it is necessary that: Y = Substituting the second equation into the first equation and rearranging yields: X – M = The fundamental equation shows that an increase in the taxes will cause the budget deficit to , which should the trade deficit.arrow_forwardWhich of the following statements is true for the small open economy? a.Saving is not always equal to investment b.Saving is always greater than investment c.Saving is always equal to investment d.Saving is always less than investment Clear my choicearrow_forwardShow the effects of expansionary policy on output and the price level in an open economy when there is full employment.arrow_forward
- In a large open economy, if households’ current income increases, then the real interest rate __________ and the equilibrium current account for this economy __________.arrow_forwardConsider 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.arrow_forwardConsider a small country that is closed to trade, so its net exports are equal to zero. The following equations describe the economy of this country in billions of dollars, where C is consumption, DI is disposable income, I is investment, and G is government purchases: C� = = 30+0.8×DI30+0.8×DI G� = = 5050 I� = = 6060 Initially, this economy had a lump sum tax. Suppose net taxes were $50 billion, so that disposable income was equal to Y – 50, where Y is real GDP. In this case, this economy's aggregate output demanded was ___________ . Suppose the government decides to increase spending by $10 billion without raising taxes. Because the spending multiplier is ____________ , this will increase the economy's aggregate output demanded by ____________ . Now suppose that the government switches to a proportional tax on income of 10%. Because consumers retain the remaining 90% of their income, disposable income is now equal to 0.90Y. In this case, the economy's aggregate output…arrow_forward
- Consider the imaginary small country of Kootenay. Assume that Kootenay is closed to trade, so that its net exports are equal to zero. Suppose that the economy is described by the following consumption function, where C is consumption, Y is income (real GDP), IP is planned investment, G is government purchases, and T is taxes: C = $40 billion+0.5×(Y – T) Suppose G=$115 billion, IP=$50 billion, and T=$10 billion. Given the consumption function and the fact that, in a closed economy, planned expenditure can be calculated as Y=C+IP+G, the equilibrium income level is billion. Suppose that government purchases are increased by $100 billion. The new equilibrium level of income will be equal to billion. Based on the effect of the change in government purchases on equilibrium income, you can tell that this economy's multiplier is equal toarrow_forwardWhich of the following statements does not belong to the main benefits of foreign direct investment (FDI)? FDI creates new jobs and boosts government tax revenues. FDI creates positive knowledge spillovers. FDI brings competition and improves efficiency. FDI makes local firms more difficult to survive and thus destroys local jobs.arrow_forwardAssume a two-period small open economy model, where the national product is 50 in the current period, and 88 in the future period. The world real interest rate is 10% per period. The representative consumer has the following utility function: U(c,G,c’,G’) = ln(c+G) + ln(c’+G’). a) What are the optimal consumption plus government spending in the current and in the future period? What is the current account surplus? Show this in a diagram. b) Now, suppose that governments in the rest of the world impose a tax on lending to foreigners of 5%. Determine how this affects consumption plus government spending in the present and the future, and the current account surplus. Explain your results. c) Suppose that governments in the rest of the world still impose a tax on lending to foreigners of 5%. However, the national country found a huge reserve of oil and the current period income increased to 100. The Determine how this affects consumption plus government spending in the present and the…arrow_forward
