26、g run.ANS:FDIF:1REF:30-3NAT:AnalyticLOC:The role of moneyTOP:Monetary neutralityMSC:InterpretiveSHORT ANSWER1.Why did farmers in the late 1800s dislike deflation?ANS:Most had large nominal debts. The decrease in the price level meant that they received less for what they produced and so made it hard

27、er to pay off the debts whose real value rose as prices fell.DIF:2REF:30-1NAT:AnalyticLOC:The role of moneyTOP:DeflationMSC:Analytical2.Explain the adjustment process in the money market that creates a change in the price level when the money supply increases.ANS:When the money supply increases, the

28、re is an excess supply of money at the original value of money. After the money supply increases, people have more money than they want to hold in their purses, wallets and checking accounts. They use this excess money to buy goods and services or lend it out to other people to buy goods and service

29、s. The increase in expenditures causes prices to rise and the value of money to fall. As the value of money falls, the quantity of money people want to hold increases so that the excess supply is eliminated. At the end of this process the money market is in equilibrium at a higher price level and a

30、lower value of money.DIF:2REF:30-1NAT:AnalyticLOC:The role of moneyTOP:Money marketMSC:Analytical3.Suppose the Fed sells government bonds. Use a graph of the money market to show what this does to the value of money.ANS:When the Fed sells government bonds, the money supply decreases. This shifts the

31、 money supply curve from MS1 to MS2 and makes the value of money increase. Since money is worth more, it takes less to buy goods with it, which means the price level falls.DIF:2REF:30-1NAT:AnalyticLOC:The role of moneyTOP:Money marketMSC:Analytical4.Using separate graphs, demonstrate what happens to

32、 the money supply, money demand, the value of money, and the price level if:a.the Fed increases the money supply.b.people decide to demand less money at each value of money.ANS:a.The Fed increases the money supply. When the Fed increases the money supply, the money supply curve shifts right from MS1

33、 to MS2. This shift causes the value of money to fall, so the price level rises.b.People decide to demand less money at each value of money. Since people want to hold less at each value of money, it follows that the money demand curve will shift to the left from MD1 to MD2. The decrease in money dem

34、and results in a lower value of money and so a higher price level.DIF:2REF:30-1NAT:AnalyticLOC:The role of moneyTOP:Money marketMSC:Analytical5.According to the classical dichotomy, what changes nominal variables? What changes real variables?ANS:The classical dichotomy argues that nominal variables

35、are determined primarily by developments in the monetary system such as changes in money demand and supply. Real variables are largely independent of the monetary system and are determined by productivity and real changes in the factor and loanable funds markets.DIF:1REF:30-1NAT:AnalyticLOC:The role

Of the following variables, which ones do not change when the money supply increases?a.real interest ratesb.inflationc.the price leveld.real outpute.real wagesf.nominal wagesANS:a.real interest ratesd.real outp

37、ute.real wagesDIF:1REF:30-1NAT:AnalyticLOC:The role of moneyTOP:Monetary neutralityMSC:Interpretive7.Wages and prices are many times higher today than they were 30 years ago, yet people do not work a lot more hours or buy fewer goods. How can this be?ANS:Inflation has raised the general price level.

38、 An increase in the general price level has no effect on real variables in the long run. Wages are higher, but so are prices. Prices are higher, but so are wages and incomes. In the long run, people change their behavior in response to changes in real variables, not nominal ones.DIF:2REF:30-1NAT:Ana

P Y

42、is nominal GDP. The amount people spend should equal the amount of money in the economy times the average number of times each unit of currency is spent.DIF:1REF:30-1NAT:AnalyticLOC:The role of moneyTOP:VelocityMSC:Definitional10.What assumptions are necessary to argue that the quantity equation imp

43、lies that increases in the money supply lead to proportional changes in the price level?ANS:We must suppose that V is relatively constant and that changes in the money supply have no effect on real output.DIF:2REF:30-1NAT:AnalyticLOC:The role of moneyTOP:Quantity theoryMSC:Definitional11.What is the

44、 inflation tax, and how might it explain the creation of inflation by a central bank?ANS:The inflation tax refers to the fact that inflation is a tax on money. When prices rise, the value of money currently held is reduced. Hence, when a government raises revenue by printing money, it obtains resour

45、ces from households by taxing their money holdings through inflation rather than by sending them a tax bill. In countries where governments are unable or unwilling to raise revenues by raising taxes explicitly, the inflation tax may be an alternative source of revenue.DIF:1REF:30-1NAT:AnalyticLOC:The role of moneyTOP:Inflation taxMSC:Interpretive12.Economists agree that increases in the money-supply growth rate increase inflation and that inflation is undesirable. So why have there been hyperinflations and how have they been ended?ANS:Typically, the government in countries t
