51。the property whereby the benefit from an extra unit of an input declines as the quantity of the input increases.
52。the rate at which a person can trade the currency of one country for the currency of another.
53.the offset in aggregate demand that results when expansionary fiscal policy raises the interest rate and thereby reduces investment spending。 54.a period of falling output and rising prices。
55。changes in fiscal policy that stimulate aggregate demand when the economy goes into a recession without policymakers having to take any deliberate action. 56。Property rights are an important prerequisite for the price system to work in a market economy。 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 financial assets of the country。 The distortion of incentives will reduce efficiency in resource allocation and will reduce saving and investment which in turn will reduce the standard of living.

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。储蓄的增加取决于储蓄的税收弹性,如果储蓄的税收弹性大，则消费会大量减少，反之，消费不会减少许多；投资的增加也取决于投资的税收弹性,如果投资的税收弹性大,则投资会大量增加,反之，投资不会增加多少。它的总效应不确定,这要看储蓄的税收效应和投资的税收效应的大小。 b） 货币供给的扩张减低了利率,利率下降意味着投资成本和消费下降，因而会刺激消费和投资增加，这是一种产生于利率变动的间接效应。它的总效应是增加社会总需求。
65。 当罗斯福总统宣布感恩前一周时，刺激了居民的消费支出，经济中对物品与劳务的需求会增加,从而总需求曲线从AD1右移到AD2。随着经济从A点变动到B点，产量从Y1增加到Y2，物价水平众P1升至P2.
