努力水平。工人选择他的收入减去努力以后的净工资w-e(努力的单位成本假设为1)最大化的努力水平。根据下列每种工资安排，确定努力水平和利润水平(收入减去支付的工资)。解释为什么这些不同的委托-代理关系产生不同的结果。
(1)对于e≥1, w=2;否则w=0。
(2)w=R/2。
(3)w=R-12.5。
A firm's short-run revenue is given by R= 10e-e2 , where e is the level of effort by a typical worker (all workers are assumed to be identical). A worker chooses his level of effort to maximize his wage net of effort w-e (the per-unit cost of effort is assumed to be 1). Determine the level of effort and the level of profit (revenue less wage paid) for each of the following wage arrangements.
Explain why these differing principal-agent relationships generate different outcomes.
a. w=2 for e≥1; otherwise w =0,
b. w= R/2.
c. w=R-12.5.
Questions are based on the following passage．
We are locked in a generational war. No one wants to admit this， because it"s uglyand unwelcome. Parents are supposed to care for their children， and children are supposedto care for their aging parents. For families， these collective obligations may work. Butwhat makes sense for families doesn"t always succeed for society as a whole. The clash ofgenerations is intensifying.
Last week， a federal judge ruled that Detroit qualifies for municipal bankruptcy.This almost certainly means that pensions and health benefits for the city"s retired workerswill be trimmed. There"s a basic conflict between paying for all retirement benefits andsupporting adequate current services. The number of Detroit"s retired workers has swelled，benefits were not adequately funded and the city"s economy isn"t strong enough to takecare of both without self-defeating tax increases.
The math is unforgiving. Detroit now has two retirees for every active worker，reports the Detroit Free Press; in 2012， that was 10，525 employees and 21，113 retirees.
Satisfying retirees inevitably shortchanges their children and grandchildren. ThoughDetroit"s situation is extreme， it"s not unique. Pension benefits were once thought to belegally and politically impregnable （不受影响的 ） . Pension cuts in Illinois， RhodeIsland and elsewhere have shattered this assumption. Chicago is considering reductionsfor its retirees.
What"s occurring at the state and local levels is an incomplete and imperfect effortto balance the interests of young and old. Conflicts vary depending on benefits" generosityand the strength——-or weakness——-of local economies. A study of 173 cities by the Centerfor Retirement Research at Boston College found pension costs averaged 7.9 percent oftax revenues， but those of many cities were much higher. Health benefits add to costs.
At the federal level， even this sloppy generational reckoning is missing. Theelderly"s interests are running roughshod （冷酷无情的） over other national concems.
Social Security， Medicare and Medicaid——programs heavily for the retired——dominate thebudget， accounting for about 44 percent of spending， and have been largely excluded fromdeficit-reduction measures.
Almost all the adjustment falls on other programs: defense， courts， research， roads，education. Or higher taxes. The federal government is increasingly a transfer agency:
Taxes from the young and middle-aged are spent on the elderly.
The explanation for this is politics. For states and localities， benefit cuts affectgovernment workers， while at the federal level， it"s all the elderly， a huge group thatincludes everyone"s parents and grandparents. As a result， the combat has beenlopsided （不平衡的 ） . Younger Americans have generally been clueless about howshifting demographics threaten their future government services and taxes.
What does the word "‘assumption" refer to in Paragraph 3？ 查看材料
A.Pensions are legal and won"t be affected by politics.
B.Pensions are easily affected by government policies.
C.Pensions are largely paid by the elderly.
D.Pensions are largely paid by tax.
Mr. Wang, a retired worker, was echoing the feelings of thousands of Beijing people as summer entered its hottest stage.
Thursday was the hottest day of the year so far, with the temperature officially reported as 36 degrees. But many people believe the government understates the real figure because regulations (条例 ) passed in the 1950s allow workers to stay at home for all or half day if the temperature is higher than 38 degrees.
" It was at least 40 degrees on Thursday, " said Liang Guojun, a middle school teacher. " It was unbearable. But the newspaper said only 36 and forecast rain. Of which there was none.
In Beijing, visitors to Daguanyuan Park in the southwest of the city said the ground temperature reached 55 degrees on Thursday.
The Beijing Evening News reported yesterday that more than 3 , 000 people had been admitted to hospitals suffering from heat stroke (中暑) , while local power companies were struggling to meet the demand for electricity.
A heat wave is sweeping much of the mainland, with temperatures in parts of Beijing, Shandong and Hebei provinces reaching as high as 39 degrees. Xinhua said the average temperature in Beijing on Thursday was 36 degrees but in the northern part of Tanghe Kou it was 39 degrees.
Hundreds of people suffering fevers were treated at hospitals. The Chaoyang hospital in northeast Beijing reported 55 such cases on Wednesday. They said most were caused by the difference in temperature between air-conditioned areas and outdoors.
Mr. Liang said the regulation on stopping work when the temperature reached 38 degrees was passed in the 1950s when Beijing had no air-conditioning and depended on fans—either handheld or electric.
"But in those days the temperature rarely reached 38 degrees, so the rule was not actually used. Now we have had years of global warming and industrial pollution and the summers get hotter each year, which means that the temperature is often higher than 38.
But an official from the Beijing Meteorological Observatory (北京气象台) said they had no knowledge of any such regulation.
