Describe how drastic inflation can undermine the ability of money to perform these three basic functions.（分数：20.00）_正确答案：()解析：Money acts as (1) a medium of exchangeenabling the purchase of goods an
31、d services, (2) a store of wealththe ability to delay purchase yet maintain wealth, and (3) a unit of accountthe assignment of a monetary value to goods and services permitting a comparison of relative value, both currently and over time. Drastic inflation refers to a period of rapid escalation in p
32、rices, meaning the purchasing power of money plummets. We may observe sellers unwilling to accept money and using it, they find its purchasing power significantly eroded. Then money is not acting as a medium of exchange. When its purchasing power is declining, money is obviously not a good store of
33、wealth. Also in such periods, borrowers benefit at the expense of savers, as they repay dollars that have lower purchasing power than the dollars they initially borrowed, and we may find some prices escalate more rapidly than others. Then money is not functioning as a good unit of account. If rampan
34、t inflation does occur, money ceases to perform its functions well and individuals may mm to barter as a means of organizing the exchange of goods and services. This is an inefficient outcome for the economy.15.Consider the following data: Nominal GDP for 1994 was 6550 billion, as compared to 6250 b

37、e Phillips curve? What does it purport to show? Why might we be interested in the relationship suggested by the Phillips curve? Explain.（分数：20.00）_正确答案：()解析：The Phillips curve depicts an inverse relationship between inflation and the unemployment rate, based on empirical data over the 1950s and 1960
38、s. It purports to show that a stable trade-off exists between unemployment and inflation. The interest in the Phillips curve arises because it presents governments with a dilemma in economic policy. Manipulation of aggregate demand fails to shift the inflation unemployment trade-off; that is the pos
39、ition of the Phillips curve. Demand management policies only enable a choice to be made about the position of the economy on the Phillips curvelow unemployment and high inflation or, by accepting higher levels of unemployment, lower levels of inflation. Thus the existence of the Phillips curve implies it is impossible to achieve low inflation and full employment simultaneously.
