ECO 302 Spring 2002 Midterm #2 Name: ____________________ ID #: _____________________ Part I: Instructions: Write your answers in the spaces provided. Show your work whenever possible. Use the back of the pages if necessary. Suppose the small, open economy of Country A is described by the following equations: Yc = current income = 28 Yf = expected future income = 30 Cd = current desired consumption = –10 + (0.5)·[Yc + Yf] – 100·r Gc = Gf = government spending (c for current, f for future) = 10 Id = current desired investment = 4 + (0.2)·Yf – 100·r rw = world real interest rate = .06 1. Fill in the blanks in the following table, and sketch in as accurately as possible the country's desired national savings and desired investment curves in the graph below: If r = .04, then Id = ________. If r = .08, then Id = ________. If r = .04, then Snd If r = .08, then Snd = ________. = ________. The country's current account balance is _______________ . –1– 2. Suppose the country's economic prospects become worse, and Yf falls to 26. Show the effects of this on the graph above. 3. Show the impact on the FE-IS-LM diagram of the reduction in Yf in question 2, assuming that markets will adjust rapidly. 4. Suppose all the country's foreign trade is with its neighbor, Upper Silesia (US). Suppose US politicians are upset about the size of Country A's current account balance, claiming that this shows that Country A is engaged in "unfair trade." They threaten to impose tariffs on all goods from Country A unless Country A's current account balance is brought closer to zero. Suppose that this threat is what caused Yf to fall in question 2. Describe the effect of this threat on Country A's current account balance. –2– 5. Suppose the government of Country A wants to take steps to bring its current account balance closer to zero. Identify at least two strategies the government could follow bring the current account balance closer to zero. For each strategy, identify whether the actions would be "expansionary" or "contractionary". Instructions: Select the one best answer for each of the following questions. Record your final choice CLEARLY next to the questions. 1. "Neutrality of money" means that changes in the money supply cause changes in: a. b. c. d. e. real interest rates. real GDP. investment spending nominal exchange rates. none of the above. 2. If utilization rates of capital and labor behave procyclically, then we would expect to observe in the data that: a. average labor productivity would be counter-cyclical. b. real wages would be procyclical. c. total factor productivity would be procyclical. d. Okun's Law would show that a less than 1% rise in output would lower the unemployment rate by 1%. e. inventory investment would be counter-cyclical. 3. When economic growth slowed down after 1973 in the USA and other developed countries, what was the predominant cause of the change? –3– a. b. c. d. e. reduced investment in new capital. increased use of imported inputs. a slowing of population growth. a decline in labor force participation. a decline in the growth rate of total factor productivity. 4. Which variables are leading? (i) (ii) (iii) inventory investment government spending stock prices a. b. c. d. e. only (i) and (ii) are true. only (i) and (iii) are true. (i), (ii), and (iii) are all true. only (iii) is true. only (i) is true. 5. In the neoclassical (Solow) growth model, suppose countries A and B share the same initial capital/worker ratio, production function, population growth rate, and depreciation rate. (Assume this initial ratio is well below the steady-state level.) If country A has a higher savings rate than country B, then (compared to country B) country A: (i) (ii) (iii) will have lower initial consumption/person. will record faster growth of output per person. will move towards a steady-state with less capital per worker. a. b. c. d. e. only (i) and (ii) are true. only (ii) and (iii) are true. all of the statements are true. only (i) and (iii) are true. none of the above. 6. In the IS-LM-FE diagram, the effect of an increase in desired consumption caused by rising expectations of future income is shown as: a. b. c. d. e. a shift to the left of the supply curve for real balances. a shift to the right of the IS curve. a shift to the right of the LM curve. a shift to the left of the FE line. a shift to the right of the demand curve for real balances. 7. If a closed economy is operating at a point below r* (the interest rate at which Snd = Id,) then the economy is operating ___________ and there is ___________ . –4– a. b. c. d. e. to the right of the FE line to the left of the IS curve to the right of the IS curve to the left of the LM curve none of the above. excess demand for labor excess supply of goods excess demand for goods excess supply of goods 8. A movement along the IS curve could be caused by; a. a shift of the desired national savings line caused by a change in government spending. b. a shift of the desired national savings line caused by a change in income. c. a shift of the desired national savings line caused by a change in desired consumption spending by households, with income held constant. d. a change in the price level. e. a shift of the desired investment line. 9. Under the Lucas misperceptions model, a worker would want to increase his labor supply only when there is an increase in the ___________. Because he lacks enough information to make a fully informed decision, he also tends to increase his labor supply when there is an increase in the ___________. a. b. c. d. e. real interest rate real wage nominal wage nominal wage none of the above. nominal interest rate nominal wage real interest rate nominal interest rate 10. We know a general equilibrium can always be attained in the IS-LM-FE diagram because: a. changes in the real interest rate will cause the IS curve to shift to meet the LM and FE lines. b. changes in the real wage will cause the FE line to shift to where the IS and LM curves meet. c. changes in the money supply will cause the LM curve to shift automatically to where the IS and FE lines meet. d. changes in the price level will cause the LM curve to shift to where the IS and FE lines meet. e. none of the above. –5– 11. The "Reverse Causation" can successfully explain why money growth is leading and procyclical _________, but cannot explain why money growth is leading and procyclical _________ . a. b. c. d. e. during expansions during recessions during Christmas shopping season following gold discoveries none of the above. during recessions during expansions following gold discoveries during Christmas shopping season 12. US President George W. Bush has made large tax cuts a major part of his economic policy. Because the USA is a large open economy and not a small open economy, these tax cuts would have a _________ effect on the current account balance than they would if the USA were a small open economy, assuming the Ricardian Doctrine does not apply. If the Ricardian Doctrine DID apply to the USA, the effect of these tax cuts on the USA's current account balance would be ___________. a. b. c. d. e. smaller negative smaller positive smaller negative larger negative larger positive zero larger even smaller even larger even larger 13. A shift to the right of the AD curve could be caused by: (i) (ii) (iii) (iv) an increase in productivity (technology shock) a tax decrease, if the Ricardian Doctrine is correct a shift to the left of the money demand curve a shift to the right of the desired investment curve a. b. c. d. e.

If there is no long-run trend in interest rates, then the money market equilibrium equation says (after some calculus has been applied to it) that inflation will be equal to zero if: a. the rate of money growth is equal to the real interest rate. b. the rate of money growth is equal to the elasticity of money demand with respect to real income. c. the rate of money growth is equal to the growth rate of nominal GDP time the elasticity of money supply with respect to output. d. the rate of money growth is equal to zero. e. none of the above. 16. The problem with accepting a production or technology shock model of business cycle behavior is that such models generally predict that: a. b. c. d. e. stock prices should be counter-cyclical instead of procyclical. consumption spending should be a lagging variable instead of coincident. labor productivity should be counter-cyclical instead of procyclical. investment spending should be counter-cyclical instead of procyclical. none of the above. 17. Suppose firms are unable to keep their inventories at their desired levels due to strong demand for their goods.

Many of the world's great cities are named after historical people. Can you name a European country whose capital city is named after a historical (not mythological) person, who was not from the country whose capital is named after him? –8–
