One reason the aggregatedemand curve slopes down is: (4) (a) Lower prices increase exports and decrease imports. (b) Higer prices leadd to a smaller real income. (c) Lower price cause smaller net capital outflows. (d) More wealth increase interest rates. 2. If domestic demand for loanable funds increases, how should this affect the value of the country's currency and its trade surplus? (4) (a) The real exchange rate will increase & the trade surplus will fall. (b) The real exchange rate will increase & the trade surplus will rise. (c) The real exchange rate will decrease & the trade surplus will fall. (d) The real exchange rate will decrease & the trade surplus will rise. 3. Which of the following would shift the short-run Phillips curve to the right? (4) (a) An increase in the money supply. (b) An increase in unemployment insurance. (c) A sudden decrease in the price of oil. (d) An increase in the amount of inflation people expact. 4. If the purchasing power parity assumption is true, which one of the following statements must be false? (4) (a) Capital flight will lower the real exchange rate. (b) If country A has more inflation than country B, country A's currency will depreciate. (c) The real price of a hambergur will be the same in all countries. (d) The relative price of a country's exports and imports will not be affected by monetary policy. 5. If the long-run aggregate suply curve shifts left and the price level expectedby people in the eonomy increases, what will happen to short-run aggregate supply? (4) (a) It will not shift. (b) It might shift left or right. (c) It must shift to right. (d) It must shift to left. 6. Under what conditions might net capital outflows (NCO) be greater than net exports (NX)? (4) (a) Whenever net exports are negative, NCO is greater than NX. (b) Under no conditions can NCO be greater than NX. (c) Only if the government does not allow imports will NCO > NX. (d) Only if there is no international trade will NCO > NX. 7. Suppose the value of the NT dollar falls so that 40 NT dollars are needed to buy a US dollar (instead of roughly 32 as is true now). How might an economist explain this depreciation? (4) (a) It could occur because the U.S. is experiencing capital flight. (b) It could occur because the domestic demand for loanable funds in Taiwan is increasing. (c) It could occur because the Taiwan government is increasing the supply of NT dollars. (d) It could occur because the Taiwan government is imposing protectionist tariffs on import. 8. Under what condition might a country's real exchange rate appreciate while its nominal exchange rate depreciates? (4) (a) This could occur if the country had a relative high rate of inflation. (b) This could occur if the country had a relative high rate of deflation. (c) Under no conditions could this occur. (d) This occurs only when the purchasing power parity assumption (PPP) is true. 9. Which component of GDP is most affected by recessions? (4) (a) consumption (b) investment (c) government (d) employment 10. Draw a Phillips curve and show what will happen if there is an unexpacted fall in the inflation rate. (4) 11. State one arguement for and one arguement against taxing savings. (2+2) 12. Assume purchasing power parity is true. Suppose a DVD cost US$30 in the United States and 3150 yen in Japan. What is the yen's nominal exchange rate? (4) 13. State one reason the purchasing power parity assumption is often not true. (4) 14. Give a simple example of an expansionary fiscal policy meant to stimulate the economy. (2) Give a simple example of an expansionary monetary policy meant to stimulate the economy. (2) 15. Suppose the government increases spending by $5 billion without raising taxes. Furthermore suppose the economy is not really in a bad recession so that every $100 of the government borrowing crouds out $95 of private investment. The marginal propensity to consume is 0.9. How much will the economy be stimulated by increase government spending. (4) 16. Suppose the central bank creates enough new money to raise the price level from 100 to 110. This is exactly what people expact the central bank to do. the economy began with a 5% unemployment rate which was the natural rate of unemployment. Given this new policy, what will happen to the unemployment rate? (2) If the government had surprised people by keeping theprice level constant at 100, what would have happend to the unemployment rate? (2) 17. Draw the 3-diagram open economy model (the loanable funds market, net capital outflow and the market of foreign currency exchange) to show what would happen to Taiwan if a crisis in China caused a massive net capital inflow back into Taiwan. (6) How would this affect Taiwan's trade surplus? (2) 18. Give one reason why short-run aggregate supply curve slopes up. (4) 19. Suppose Y=100, G=20, C=60, I=25 and M (imports) =20. How much are net capital outflows (NCO)? (2) How much is being exported? (2) 20. How does unemployment insurance act as an automatic stabilizer? (4) 21. State one reason most economists think deflation is more harful than inflation. (4) 22. What long-term effect does inflation have on the nominal interest rate?(4) 23. If one graphs the relationship between Taiwan's inflation rate and its unemployment rate, the relationship between the to predicted by the Phillips curve is not very obvious. Give one possible reason why this might be. (4) 24. Schumpeter (a famous economist) introduced the concept of "creative destruction" to argue that recessions could be good for an economy. Why did he think recessions could be good? (4) 希望不要有人先打完...... --
