If an individual or company is not confident that claims over property or over the income from property can be protected, or that contracts can be enforced, there will be little incentive for individuals to save, invest, or start new businesses. Likewise, there will be little incentive for foreigners to invest in the real or financialassets of the country. The distortion of incentives will reduce efficiency in resource allocation and willreduce saving and investment which in turn will reduce the standard of living.57. a.A municipal bond, because generally they have low credit risk and are notsubject to federal income tax. b. A junk bond. Because of their high risk, they have a high return.c. A corporate bond that isn't a junk bond. Because they have more risk than government bonds and have no special tax treatment, they pay moderate rates of return.58.First National Bank of Me Assets Liabilities Reserves $800 Deposits$5,000Loans$4,20059.The costs of inflation include "shoeleather costs," the cost of reducing your money holdings to reduce your inflation tax; "menu costs," the costs of price adjustments; the costs of resource misallocation that result from the relative-price variability induced by inflation; the costs of inflation-induced tax distortions; the costs of confusion and inconvenience; and the costs associated with the arbitrary redistribution of wealth that accompany unexpected inflation.60.Examples in the text (or variations) include increased immigration, a decrease in the minimum wage, more generous unemployment insurance, an increase in the capital stock, an increase in the average level of education, a discovery of new mineral deposits, technology, and removal of barriers to international trade.61.See graph.Over time technological advances cause the long-run aggregate supply curve to shift right. Increases in the money supply cause the aggregate demand curve to shift right. Output growth puts downward pressure on the price level, but money supply growth contributes to rising prices.62.The wealth effect is not very important because it operates through changes in the real value of money, and money is only a small fraction of household wealth. So it is unlikely that changes in the price level will lead to large changes in consumption spending through this channel. The exchange-rate effect is not very important in the United States because trade with other countries represents a relatively small fraction of U.S. GDP.63. If the interest rate is above equilibrium, there is an excess supply of money. People with more money than they want to hold given the current interest rate deposit the money in banks and buy bonds. The increase in funds to lend out causes the interest rate to fall. As the interest rate falls, the quantity of money demanded increases, which tends to diminish the excess supply of money.64. a) 税收减少增加了储蓄的收益、减少了投资的成本，但税收减少对储蓄和投资的影响要视情况而定。
