Lesson4 Is an Ivy League Diploma Worth It？花钱读常春藤名校值不值？1.如果愿意的话，施瓦茨（Daniel Schwartz）本来是可以去一所常春藤联盟（Ivy League）院校读书的。
他只是认为不值。
2.18 岁的施瓦茨被康奈尔大学（Cornell University）录取了，但他最终却去了纽约市立大学麦考利荣誉学院（City University of New York’s Macaulay Honors College），后者是免费的。
3.施瓦茨说，加上奖学金和贷款的支持，家里原本是可以付得起康奈尔的学费的。
但他想当医生，他觉得医学院是更有价值的一项投资。
私立学校医学院一年的花费动辄就要4 万5 美元。
他说，不值得为了一个本科文凭一年花5 万多美元。
4.助学贷款违约率日益攀升，大量的大学毕业生找不到工作，因此越来越多的学生认定，从一所学费不太贵的学校拿到的学位和从一所精英学校拿到的文凭没什么区别，并且不必背负贷款负担。
5.Robert Pizzo 越来越多的学生选择收费较低的公立大学，或选择住在家里走读以节省住房开支。
美国学生贷款行销协会（Sallie Mae）的一份报告显示，2010 年至2011 学年，家庭年收入10 万美元以上的学生中有近25%选择就读两年制的公立学校，高于上一学年12%的比例。
6.这份报告称，这样的选择意味着，在2010 至2011 学年，各个收入阶层的家庭在大学教育上的花费比上一年少9%，平均支出为21,889 美元，包括现金、贷款、奖学金等。
高收入家庭的大学教育支出降低了18%，平均为25,760 美元。
这份一年一度的报告是在对约1,600 名学生和家长进行问卷调查后完成的。
7.这种做法是有风险的。
顶级大学往往能吸引到那些已经不再去其他学校招聘的公司前来招聘。
在许多招聘者以及研究生院看来，精英学校的文凭还是更有吸引力的。
CHAPTER 55-1. Suppose the labor supply curve is upward sloping and the labor demand curve is downward sloping. The study of economic trends over a particular time period reveals that the wage recently fell while employment levels rose. Which curve must have shifted and in which direction to produce this effect?If the supply curve does not shift, all wage and employment movements must occur along the supply curve, so that the wage rate and the employment level must move in the same direction. Because the wage went down while employment went up in the situation described in the question, it must have been the case that the supply curve shifted outwards (to the right). We do not have enough information to determine whether the demand curve shifted as well.5-2. It takes time to produce a new economist, and prospective economists base their career decision by looking only at current wages across various professions. Further, the labor supply curve of economists is much more elastic than the labor demand curve. Suppose the market is now in equilibrium, but that the demand for economists suddenly rises because a new activist government in Washington wants to initiate many new programs that require the input of economists. Illustrate the trend in the employment and wages of economists as the market adjusts to this increase in demand.Initially, the market is in equilibrium at a wage w0 and an employment level of E0. The increase the demand for economists results in a new equilibrium wage of w1 and a new equilibrium employment level of E1. However, the demand for economists in the short-run is inelastic at E0, so the demand increase simply leads to a rise in the wage of economists (as indicated by point 1). In the next period, students believe this wage will persist and oversupply the market so that the cobweb leads to a new wage at point 2. In the next period, students undersupply (because the wage is too low) and the cobweb leads to a new wage at point 3, and so on. Because of the relative elasticities of supply and demand (as drawn), the cobweb is exploding and will never converge to a stable equilibrium.5-3. Suppose the supply curve of physicists is given by w = 10 + 5E , while the demand curve is given by w = 50 – 3E . Calculate the equilibrium wage and employment level. Suppose now that the demand for physicists increases and the new demand curve is given by w = 70 – 3E . Assume this market is subject to cobwebs. Calculate the wage and employment level in each round as the wage and employment levels adjust to the demand shock. (Recall that each round occurs on the demand curve – when the firm posts a wage and hires workers). What is the new equilibrium wage and employment level?The initial equilibrium is given by 10 + 5E = 50 – 3E . Solving these two equations simultaneously implies that w = $35 and E S = E D = 5. When demand increases to w = 70 – 3E , the new equilibrium wage is $47.5 and the equilibrium level of employment is 7.5.Round Wage Employment1 $55.0 52 $43.0 93 $50.2 6.64 $45.9 8.05 $48.4 7.26 $46.9 7.77 $47.8 7.48 $47.2 7.6The table gives the values for the wage and employment levels in each round. The values in the table are calculated by noting that in any given period the number of physicists is inelastically supplied, so that the wage is determined by the demand curve. Given this wage, the number of economists available in the next period is calculated. By round 7, the market wage rate is within 30 cents of the new equilibrium.01 w 1w 0W age5-4. The 1986 Immigration Reform and Control Act (IRCA) made it illegal for employers in the United States to knowingly hire illegal aliens. The legislation, however, has not reduced the flow of illegal aliens into the country. As a result, it has been proposed that the penalties against employers who break the law be increased substantially. Suppose that illegal aliens, who tend to be less skilled workers, are complements with native workers. What will happen to the wage of native workers if the penalties for hiring illegal aliens increase?A substantial increase in the penalties associated with hiring illegal aliens will likely reduce the number of illegal aliens entering the United States. The effect of this shift in the size of the illegal alien flow on the marginal product (and hence the demand curve) of native workers hinges on whether illegal aliens are substitutes or complements with natives. As it is assumed that natives and illegal aliens are complements, a cut in the number of illegal aliens reduces the value of the marginal product of natives, shifting down the demand for native labor, and decreasing native wages and employment.5-5. Suppose a firm is a perfectly discriminating monopsonist. The government imposes a minimum wage on this market. What happens to wages and employment?A perfectly discriminating monopsonist faces a marginal cost of labor curve that is identical to the supply curve. As a result, the employment level of a perfectly discriminating monopsonist equals theemployment level that would be observed in a competitive market (at E *) The imposition of a minimum wage at w MIN leads to the same result as in a competitive market: the firm will only want to hire E D workers as w MIN is now the marginal cost of labor, but E S workers will want to find work at the minimum wage. Thus, the wage increases, but employment falls.DollarsE w w *S D5-6. What happens to wages and employment if the government imposes a payroll tax on amonopsonist? Compare the response in the monopsonistic market to the response that would have been observed in a competitive labor market.Initially, the monopsonist hires E M workers at a wage of w M . The imposition of a payroll tax shifts the demand curve to VMP ′, and lowers employment to E ′ and the wage to w ′. Thus, the effect of imposing a payroll tax on a monopsonist is qualitatively the same as imposing a payroll tax in a competitive labor market: lower wages and employment. (It is interesting to note that the same result comes about if the payroll tax is placed on workers, so that the labor supply and marginal cost of labor curves shift as opposed to labor demand.)5-7. An economy consists of two regions, the North and the South. The short-run elasticity of labor demand in each region is –0.5. The within-region labor supply is perfectly inelastic. The labormarket is initially in an economy-wide equilibrium, with 600,000 people employed in the North and 400,000 in the South at the wage of $15 per hour. Suddenly, 20,000 people immigrate from abroad and initially settle in the South. They possess the same skills as the native residents and also supply their labor inelastically.(a) What will be the effect of this immigration on wages in each of the regions in the short run (before any migration between the North and the South occurs)?There will be no effect on the North’s labor supply in the short run, so the wage rate will not change there. In the South, labor supply will have increased by 5 percent, so the wage rate must fall by 5/(0.5) = 10 percent (recall that the elasticity of labor demand is -0.5, so a one percent decrease in wages would have been generated by a 0.5 percent expansion of the labor supply). The new hourly wage in the South, therefore, is $13.50 and total employment in the South is 420,000.DollarsEmploymentw M w ′(b) Suppose 1,000 native-born persons per year migrate from the South to the North in response to every dollar differential in the hourly wage between the two regions. What will be the ratio of wages in the two regions after the first year native labor responds to the entry of the immigrants?After the initial migration, we have seen that wages in the South are $13.50 while wages in the North are $15. This difference leads 1,500 natives migrating from the South to the North in the first year. Employment in the North after one year, therefore is 601,500. Moreover, as the elasticity of labor demand in the North is -0.5 and employment has increased by 0.25 percent, the Northern wage falls by 0.5 percent to roughly $14.93. Likewise, employment in the South after one year is 418,500. As the elasticity of labor demand is -0.5 and employment has decreased by 0.3571 percent, the Southern wage increases by0.71428 percent to roughly $13.60. Thus, the ratio of the Northern to Southern wage after one year is1.09779.(c) What will be the effect of this immigration on wages and employment in each of the regions in the long run (after native workers respond by moving across regions to take advantage of whatever wage differentials may exist)? Assume labor demand does not change in either region.In the long run, people must move from the South to the North to equalize the wage rates in the two regions. Since the wages were equal in the two regions before the influx of immigrants, and they also must be equal after things settle down, the proportional decrease in the wage rate should be the same in the North and in the South. Because the elasticity of labor demand is the same in the two regions, this last observation implies that the percentage increase in employment in the North must be the same as the percentage increase in employment in the South. Thus, as 60 percent of the original workers were employed in the North, 60 percent of the 20,000 increase in Southern employment will eventually migrate to the North. In the long run, therefore, total Northern employment will be 612,000 while total Southern employment will be 408,000. (Note: there is no presumption that only immigrants further migrate to the North.) In each region, therefore, employment increases by 2 percent in the long run, i.e., 12,000 is 2 percent of 600,000 and 8,000 is 2 percent of 400,000. (This can also be seen immediately as 20,000 is 2 percent of the 1 million workers.) Now, given that the elasticity of labor demand is -0.5, the 2 percent increase in employment will cause the wage rate to fall by 4 percent. Hence, the long-run equilibrium hourly wage will be $14.40.5-8. Chicken Hut faces perfectly elastic demand for chicken dinners at a price of $6 per dinner. The Hut also faces an upward sloped labor supply curve ofE = 20w – 120,where E is the number of workers hired each hour and w is the hourly wage rate. Thus, the Hut faces an upward sloped marginal cost of labor curve ofMC E = 6 + 0.1E.Each hour of labor produces 5 dinners. (The cost of each chicken is $0 as the Hut receives two-day old chickens from Hormel for free.) How many workers should Chicken Hut hire each hour to maximize profits? What wage will Chicken Hut pay? What are Chicken Hut’s hourly profits?First, solve for the labor demand curve: VMP E = P x MP E = $6 x 5 = $30. Thus, every worker is valued at $30 per hour by Chicken Hut. Now, setting VMP E = MC E yields 30 = 6 + .1E which implies E* = 240. Thus, Chicken Hut will hire 240 workers every hour. Further, according to the labor supply curve, 240 workers can be hired at an hourly wage of $18. Finally, Chicken Hut’s profits are Π = 240(5)($6) –240($18) = $2,880.5-9. Polly’s Pet Store has a local monopoly on the grooming of dogs. The daily inverse demand curve for pet grooming is:P = 20 – 0.1Qwhere P is the price of each grooming and Q is the number of groomings given each day. This implies that Polly’s marginal revenue is:MR = 20 – 0.2Q.Each worker Polly hires can groom 20 dogs each day. What is Polly’s labor demand curve as a function of w, the daily wage that Polly takes as given?As each worker can groom 20 dogs each day, and using Q = 20E, we have thatVMP E = MR x MP E = ( 20 – 0.2Q ) (20) = (20 – 4E)(20) = 400 – 80E.Thus, as Polly’s demand for labor satisfies VMP E = w, we have that her labor demand curve isE = 5 – 0.0125w.5-10. The Key West Parrot Shop has a monopoly on the sale of parrot souvenir caps in Key West. The inverse demand curve for caps is:P = 30 – 0.4 Qwhere P is the price of a cap and Q is the number of caps sold per hour. Thus, the marginal revenue for the Parrot Shop is:MR = 30 – 0.8Q.The Parrot Shop is the only employer in town, and faces an hourly supply of labor given by:w = 0.9E + 5where w is the hourly wage rate and E is the number of workers hired each hour. The marginal cost associated with hiring E workers, therefore, is:MC E = 1.8E + 5.Each worker produces two caps per hour. How many workers should the Parrot Shop hire each hour to maximize its profit? What wage will it pay? How much will it charge for each cap?First, as Q = 2E, the labor demand curve isVMP E = MR x MP E = (30 – 0.8Q)(2) = 60 – 1.6Q = 60 – 3.2E.Setting VMP E equal to MC E and solving for E yields E = 11. Eleven workers can be hired at a wage of.9(11) + 5 = $14.99 per hour. The 11 workers make 22 caps each hour, and the 22 caps can be sold at a price of 30 – 0.4(22) = $21.20 each.5-11. Ann owns a lawn mowing company. She has 400 lawns she needs to cut each week. Her weekly revenue from these 400 lawns is $20,000. If given an 18-inch deck push mower, a low-skill worker can cut each lawn in two hours. If given a 60-inch deck riding mower, a low-skill worker can cut the lawn in 30 minutes. Low-skilled labor is supplied inelastically at $5.00 per hour. Each laborer works 8 hours a day and 5 days each week.(a) If Ann decides to have her workers use push mowers, how many push mowers will Ann rent and how many workers will she hire?As each worker can cut a lawn in 2 hours, it follows that each worker can cut 4 lawns in a day or 20 lawns in a week. Therefore, Ann would need to rent 20 push mowers and hire 20 workers in order to cut all 400 lawns each week.(b) If she decides to have her workers use riding mowers, how many riding mowers will Ann rent and how many workers will she hire?As each worker can cut a lawn in 30 minutes, it follows that each worker can cut 16 lawns in a day or 80 lawns in a week. Therefore, Ann would need to rent 5 riding mowers and hire 5 workers in order to cut all 400 lawns each week.(c) Suppose the weekly rental cost (including gas and maintenance) for each push mower is $250 and the weekly rental cost (including gas and maintenance) of each riding mower is $1,800. What equipment will Ann rent? How many workers will she employ? How much profit will she earn?If Ann uses push mowers, her weekly cost of mowers is $250(20) = $5,000 while her weekly labor cost is $5(20)(40) = $4,000. Under this scenario, her weekly profit is $11,000. If Ann uses riding mowers, her weekly cost of mowers is $1,800(5) = $9,000 while her weekly labor cost is $5(5)(40) = $1,000. Thus, under this scenario, her weekly profit is $10,000. Therefore, under these conditions, Ann will rent 20 push mowers and employ 20 low-skill workers.(d) Suppose the government imposes a 20 percent payroll tax (paid by employers) on all labor and offers a 20 percent subsidy on the rental cost of capital. What equipment will Ann rent? How many workers will she employ? How much profit will she earn?Under these conditions, the cost of labor has increased to $6.00 per hour, while the rental costs for a push mower and a riding mower have decreased to $200 and $1,440 respectively. Ann’s profits under the two options, therefore, arePush-Profit = $20,000 – $200(20) – $6(20)(40) = $11,200.Rider-Profit = $20,000 – $1,440(5) – $6(5)(40) = $11,600.Thus, under these conditions, Ann rents riding mowers, hires 5 low-skill workers, and earns a weekly profit of $11,600.5-12. In the United States, some medical procedures can only be administered to a patient by a doctor while other procedures can be administered by a doctor, nurse, or lab technician. What might be the medical reasons for this? What might be the economic reasons for this?The American Medical Association might argue that doctors have more training and experience than nurses, and therefore, are the only professionals who can make certain decisions or perform certain procedures.Economically, the AMA has an incentive to restrict the number of people who can practice medicine (or perform certain procedures) in order to keep doctor wages high. If nurses were allowed to do everything they were capable of, fewer doctors would be demanded, and doctor wages would fall. From an economic viewpoint, therefore, the AMA restricts the supply of doctors, which keeps doctor wages artificially high.WageW restW unrestRestricted Supply ofDoctorsUnrestricted Supplyof DoctorsL rest L unrest Services Provided by DoctorsLabor Market For Medical Services Provided by Doctors。
