Describe the difference between average revenue and marginal reve-nue. Why are both of these revenue measures important to a prof-it-maximizing firm?ANS:Average revenue is total revenue divided by the quantity of output. Marginal revenue is the change in total revenue from the sale of each additional unit of output. Marginal revenue is used to determine the profit-maximizing level of production, and average revenue is used to help determine the level of profits. Note that for all firms, price equals average revenue because AR=(PxQ)/Q=P. But only for a firm operating in a perfectly competitive industry does price al-so equal marginal revenue.DIF: 2 REF: 14-1 NAT: Analytic LOC: Perfect competitionTOP: Price MSC: D efinitional2. List and describe the characteristics of a perfectly competitive market. ANS:There are many buyers and sellers in the market. The goods offered by the various sellers are largely the same. Firms can freely enter or exit the market. DIF: 2 REF: 14-1 NAT: Analytic LOC: Perfect competitionTOP: Competitive markets MSC: D efinitional3. Why would a firm in a perfectly competitive market always choose to set its price equal to the current market price? If a firm set its price below the current market price, what effect would this have on the market?ANS:The firm could not sell any more of its product at a lower price than it could sell at the market price. As a result, it would needlessly forgo revenue if it set a price below the market price. If the firm set a higher price, it would not sell anything at all because a competitive market has many sellers who would supply the product at the market price.DIF: 2 REF: 14-1 NAT: Analytic LOC: Perfect competitionTOP: Profit maximization MSC: A nalytical4. Use a graph to demonstrate the circumstances that would prevail in a competitive market where firms are earning economic profits. Can this sce-nario be maintained in the long run?

Explain how a firm in a competitive market identifies the prof-it-maximizing level of production. When should the firm raise production, and when should the firm lower production? ANS:The firm selects the level of output at which marginal revenue is equal tomarginal cost. If MR > MC, profit will increase if the firm increases Q. If MR < MC, profit will increase if the firm decreases Q. DIF: 2 REF: 14-2 NAT: AnalyticLOC: Perfect competition TOP: Profit maximization MSC: A nalytical6. News reports from the western United States occasionally report inci-dents of cattle ranchers slaughtering a large number of newborn calves and burying them in mass graves rather than transporting them to markets. As-suming that this is rational behavior by profit-maximizing "firms," explain what economic factors may influence such behavior.ANS:If the selling price is not sufficient to cover the variable cost of sending the calves to market, this (potentially emotionally upsetting) behavior makes economic sense.DIF: 2 REF: 14-2 NAT: AnalyticLOC: Perfect competition TOP: Profit maximization MSC: A nalytical。

Even though monetary policy is neutral in the short run, it may have profound real effects in the long run. ANS: F DIF: 1 REF: 30-3NAT: Analytic LOC: The role of money TOP: 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 harder to pay off the debts whose real value rose as prices fell.DIF: 2 REF: 30-1 NAT: AnalyticLOC: The role of money TOP: Deflation MSC: Analytical2. Explain the adjustment process in the money market that creates a change in the price level when the moneysupply increases.ANS:When the money supply increases, there 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 services. 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 lower value of money.DIF: 2 REF: 30-1 NAT: AnalyticLOC: The role of money TOP: Money marketMSC: Analytical2018 Chapter 30 /Money Growth and Inflation3. Suppose the Fed sells government bonds. Use a graph of the money market to show what this does to the valueof money.ANS:When the Fed sells government bonds, the money supply decreases. This shifts the 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: 2 REF: 30-1 NAT: AnalyticLOC: The role of money TOP: Money marketMSC: Analytical4. Using separate graphs, demonstrate what happens to 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 curveshifts right from MS1 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 eachvalue of money, it follows that the money demand curve will shift to the left from MD1 to MD2. Thedecrease in money demand results in a lower value of money and so a higher price level.DIF: 2 REF: 30-1 NAT: AnalyticLOC: The role of money TOP: Money marketMSC: Analytical5. According to the classical dichotomy, what changes nominal variables? What changes real variables? ANS:The classical dichotomy argues that nominal variables 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: 1 REF: 30-1 NAT: AnalyticLOC: The role of money TOP: Classical dichotomyMSC: Definitional6. Suppose that monetary neutrality holds. Of the following variables, which ones do not change when themoney supply increases?a. real interest ratesb. inflationc. the price leveld. real outpute. real wagesf. nominal wagesANS:a. real interest ratesd. real outpute. real wagesDIF: 1 REF: 30-1 NAT: AnalyticLOC: The role of money TOP: Monetary neutralityMSC: Interpretive7. Wages and prices are many times higher today than they were 30 years ago, yet people do not work a lot morehours or buy fewer goods. How can this be?ANS:Inflation has raised the general price level. 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: 2 REF: 30-1 NAT: AnalyticLOC: The role of money TOP: Nominal variables | Real variablesMSC: Interpretive8. Identify each of the following as nominal or real variables.a. the physical output of goods and servicesb. the overall price levelc. the dollar price of applesd. the price of apples relative to the price of orangese. the unemployment ratef. the amount that shows up on your paycheck after taxesg. the amount of goods you can purchase with the wage you get each hourh. the taxes that you pay the governmentANS:a. real variableb. nominal variablec. nominal variabled. real variablee. real variablef. nominal variableg. real variableh. nominal variableDIF: 1 REF: 30-1 NAT: AnalyticLOC: The role of money TOP: Nominal variables | Real variablesMSC: Interpretive2020 Chapter 30 /Money Growth and Inflation9. Define each of the symbols and explain the meaning o f M V = P Y.ANS:M is the quantity of money, V is the velocity of money, P is the price level, and Y is the quantity of o utput. P Y 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: 1 REF: 30-1 NAT: AnalyticLOC: The role of money TOP: Velocity MSC: Definitional10. What assumptions are necessary to argue that the quantity equation implies that increases in the money supplylead 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: 2 REF: 30-1 NAT: AnalyticLOC: The role of money TOP: Quantity theoryMSC: Definitional11. What is the 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 resources 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: 1 REF: 30-1 NAT: AnalyticLOC: The role of money TOP: Inflation tax MSC: Interpretive12. Economists agree that increases in the money-supply growth rate increase inflation and that inflation isundesirable. So why have there been hyperinflations and how have they been ended?ANS:Typically, the government in countries that had hyperinflation started with high spending, inadequate tax revenue, and limited ability to borrow. Therefore, they turned to the printing presses to pay their bills. Massive and continued increases in the quantity of money led to hyperinflation, which ended when the governments instituted fiscal reforms eliminating the need for the inflation tax and subsequently slowed money supply growth.DIF: 2 REF: 30-1 NAT: AnalyticLOC: The role of money TOP: HyperinflationMSC: Interpretive13. Suppose that velocity and output are constant and that the quantity theory and the Fisher effect both hold.What happens to inflation, real interest rates, and nominal interest rates when the money supply growth rate increases from 5 percent to 10 percent?ANS:Inflation and nominal interest rates each increase by 5 percent points. There is no change in the real interest rate or any other real variable.DIF: 1 REF: 30-1 NAT: AnalyticLOC: The role of money TOP: Inflation MSC: Analytical14. In recent years Venezuela and Russia have had much higher nominal interest rates than the United Stateswhile Japan has had lower nominal interest rates. What would you predict is true about money growth in these other countries? Why?ANS:The Fisher effect says that increases in the inflation rate lead to one-to-one increases in nominal interest rates. The quantity theory says that in the long run, inflation increases one-to-one with money supply growth. It follows that differences in nominal interest rates may be due to differences in money supply growth rates. It is reasonable to guess that much higher nominal interest rates in Venezuela and Russia indicate higher money supply growth while lower interest rates in Japan indicate lower money supply growth.DIF: 1 REF: 30-1 NAT: AnalyticLOC: The role of money TOP: Fisher effect MSC: Applicative15. The U.S. Treasury Department issues inflation-indexed bonds. What are inflation-indexed bonds and why arethey important?ANS:Inflation-indexed bonds are bonds whose interest and principal payments are adjusted upward for inflation, guaranteeing their real purchasing power in the future. They are important because they provide a safe, inflation- proof asset for savers and they may allow the Treasury to borrow more easily at a lower current cost.DIF: 1 REF: 30-1 NAT: AnalyticLOC: The role of money TOP: Index bonds MSC: Definitional16. List and define any two of the costs of high inflation.ANS:The costs include:Shoeleather costs: the resources wasted when inflation induces people to reduce their money holdings.Menu costs: the cost of more frequent price changes at higher inflation rates.Relative Price Variability: because prices change infrequently, higher inflation causes relative prices to vary more. Decisions based on relative prices are then distorted so that resources may not be allocated efficiently.Inflation Induced Tax Distortions: the income tax is not completely indexed for inflation; an increase in nominal income created by inflation results in higher real tax rates that discourage savings.Confusion and Inconvenience: inflation decreases the reliability of the unit of account making it more complicated to differentiate successful and unsuccessful firms thereby impeding the efficient allocation of funds to alternative investments.Unexpected Inflation: inflation decreases the real value of debt thereby transferring wealth from creditors to debtors. DIF: 1 REF: 30-2 NAT: AnalyticLOC: The role of money TOP: Inflation costsMSC: Definitional17. Inflation distorts relative prices. What does this mean and why does it impose a cost on society?ANS:Relative prices are the value of one good in terms of other goods. Relative prices ordinarily provide signals concerning therelative scarcity of goods so the goods may be allocated efficiently. Some prices change infrequently, so that when inflation rises, there is greater variation in relative prices. However, changes in relative prices created by inflation do not signal changes in the scarcity of goods and so lead to an inefficient allocation of goods and resources.DIF: 1 REF: 30-2 NAT: AnalyticLOC: The role of money TOP: Relative price variabilityMSC: Interpretive18. Explain how inflation affects savings.ANS:Inflation discourages savings. Income tax is collected on nominal rather than real interest rates. So an increase in inflation will increase nominal interest rates and taxes. The increase in taxes in turn lowers the real return on savings and so discourages savings.DIF: 1 REF: 30-2 NAT: AnalyticLOC: The role of money TOP: Saving | InflationMSC: Applicative2022 Chapter 30 /Money Growth and Inflation19. The U.S. Treasury Department began issuing inflation-indexed bonds in early 1997. Since these assets arevirtually risk free, both in terms of default risk and inflation risk, will they quickly replace all other kinds of assets that still entail risk of one kind or another, such as ordinary government bonds or corporate bonds?Explain.ANS:When individuals are choosing between assets of different kinds, they consider both expected return and risk. Because the new inflation-indexed bonds have very low risk, they will also have very low real interest rates. So they will not replace other, more risky assets that promise to pay a much higher real interest rate. They do, however, offer a way of escaping some inflation risk, and have become a popular addition to portfolios.DIF: 1 REF: 30-2 NAT: AnalyticLOC: The role of money TOP: Index bonds MSC: AnalyticalSec00 - Money Growth and InflationMULTIPLE CHOICE1.

Explain the difference between absolute advantage and comparative advantage. Which is more important indetermining trade patterns, absolute advantage or comparative advantage? Why?ANS:Absolute advantage refers to productivity, as in the producer who can produce a product at a lower cost in terms of the resources used in production. Comparative advantage refers to the producer who can produce a product at a lower opportunity cost. Comparative advantage is the principle upon which trade patterns are based. Comparative advantage is based on opportunity cost, and opportunity cost measures the real cost to an individual or country of producing a particular product. Opportunity cost is therefore the information necessary for an individual or nation to determine whether to produce a good or buy it from someone else.DIF: 2 REF: 3-2 NAT: AnalyticLOC: Gains from trade, specialization and tradeTOP: Absolute advantage | Comparative advantage | Trade MSC: Interpretiveword 文档 可自由复制编辑2.
