28、ustry for national security reasons, and it imposes a tariff of 6 per dozen. What are the new equilibrium price, domestic consumption, domestic production, and imports?（分数：20.00）_正确答案：()解析：(a)Without a tariff, the domestic equilibrium price is the world price of 24. The domestic consumption equilibr
29、ium is QD(24)=100,000-2,000(24)=52,000. Domestic supply is QS(24)=-10,000+1,000(24)=14,000, so imports equal 38,000.(b)The new equilibrium price is 24+6=30. After the tariff, domestic demand is Q D(30)= 100,000-2,000(30)=40,000, and domestic supply is QS(30)=-10,000+1,000(30) = 20,000; imports there

Suppose that restrictions on interstate competition in the market for financial services lead to a large expansion of the financial services sector in the city. (a)What
31、effect do you predict that this increase in jobs would have oil wages and housing prices in the city? (b)What effect do you think there would be on the manufacturing sector in the city? Would you expect that manufacturing employment would rise or fall?（分数：20.00）_正确答案：()解析：(a)An increase in the deman
32、d for labor should increase wages in equilibrium. Higher wages will attract new workers to the city, as well as raise the incomes of all workers in the city. This, in turn, should increase the demand for housing, and thus raise the price of housing. (b)Wages in the manufacturing sector would presuma
33、bly rise due to competition for workers from other sectors. Increased housing would also raise the wages needed to attract new workers from other cities. Thus, this citys manufacturing sector faces higher costs than manufacturing in the other cities. If file electronics industry is mobile, firms are
34、 likely to transfer production to other cities. Hence, manufacturing employment will likely fall when employment in the other sectors rises.13.You are deciding whether to purchase a used car. The price of the car is 1,400 and you expect the car to last for four years. You have determined that the va
35、lue of the flow of services you will receive from the car in each of the four years is 500. The interest rate is 20 percent. (Assuming that all figures are real terms.) (a)Without discounting future cash flows and benefit streams, is the benefit of buying this car greater than the cost? (b)When cost
36、s and benefits are appropriately valued, what is the net present value of this investment? Should you buy the car?（分数：20.00）_正确答案：()解析：(a)The stream of benefits for the four years is 500+500+500+500=2,000.The stream of costs over the four years is 1,400+100+100+100=1,700.Therefore, the benefits outw
37、eigh the costs.(b)The PV of the benefit stream is 500/(1+20%)+500/(1+20%)2+500/(1+20%) 3+500/(1+ 20%)4=416.67+347.22+289.35+241.13=1,294.37.The cost of the car is 1,400. The net present value is negative (1,294.37-1,400=-105.63), and therefore you should not buy the car.14.Explain: “Ms Smith diminis
38、hes the national income by marrying her cook“, hi what way is this true by definition of GDP? Is this one of the problems with the use of GDP as a measure of social welfare?（分数：20.00）_正确答案：()解析：When Ms Smith employed her cook, the meals he produced were part of his employment contract. The transacti
39、on between the two would be a market one. The value he added to the food he prepared would form part of GDP. Once Ms Smith realised that there was more to her cook than just his meals and she married him, presumably the employment contract would fall away. Although the cook would still add the same
40、value to the meals he prepared, he would not charge for the service nor would he render a tax return in respect of these cooking activities. The activity would now be classified as a non-market one. The activities are now “within the family“ and so are not included in the national income and to that
41、 extent the act of marriage has led to a fall in GDP. Some would equate the creation of GDP with the attainment of social welfare. However, although GDP does provide a relatively good measure of economic or material wellbeing, it is an imperfect indicator of social welfare. Neither Ms Smiths economi
42、c nor her social wellbeing has been altered by her marriage to her cook (at least not as regards the cookery services provided by her cook/husband).15.Assume that GDP grew from 120 billion in 1994 to 160 billion in 1995 and the GDP deflator from 100 in 1994 to 130 in 1995.

45、rease the equilibrium GDP by n dollars“. Does this hold true regardless of the size of the MPS?（分数：20.00）_正确答案：()解析：Yes, this is true. When government spending changes, the additional income generated enters the income stream immediately from the first expenditure round. Tax changes of equal value do not have an equivalent impact on expenditure in the first round. This is because taxes impact on disposable income first and then upon expenditure. Suppose MPS is 0.1 and let n=100. The question suggests that gov
