Suppose that fixed costs for a firm in the automobile industry (start-up costs of factories, capital equipment, and so on) are $5 billion and that variable costs are equal to $17,000 per finished automobile. Because more firms increase competition in the market, the market price falls as more firms enter an automobile market, or specifically, where n represents the number of firms in a market. Assume that the initial size of the U.S. and the European automobile markets are 300 million and 533 million people, respectively. a. Calculate the equilibrium number of firms in the U.S. and European automobile markets without trade. b. What is the equilibrium price of automobiles in the United States and Europe if the automobile industry is closed to foreign trade？ c. Now suppose that the United States decides on free trade in automobiles with Europe. The trade agreement with the Europeans adds 533 million consumers to the automobile market, in addition to the 300 million in the United States. Howmany automobile firms will there be in the United States and Europe combined？ What will be the new equilibrium price of automobiles？

根据下列文章,请回答 36～40 题。 Exercise Lowers Employers’Health Costs

Companies can save millions in health-care costs simply by encouragingtheir employees to exercise a little bit，researchers reported on Friday．

They said obese(肥胖的)employeeshad higher health-care costs，but lowered those expenses by exercising just acouple of times a week—without even losing any weight．

Feifei Wang andcolleagues at the University of Michigan studied 23，500 workers at GeneralMotors．They estimated that getting the most sedentary(惯于久坐的)obese workers to exercisewould have saved about$790，000 a year，or about 1.5 percent of health-care costsfor the whole group．

Company-wide．thepotential savings could reach$7.1 million per year，they reported in the Journalof Occupational and Environmental，Medicine．

Of the whole groupof workers。about 30 percent were of normal weight，45 percent were overweight(超重的)，and25 percent were obese．Annual health—care costs averaged$2，200 for normal weight，$2，400for the overweight，and$2，700 for obese employees．

But among workerswho did no exercise，health—care costs went up by at least$1 00 a year，andwere$3，000 a year for obese employees who were sedentary．

But adding two ormore days of light exercise—at least 20 minutes of exercise or work hard enoughto increase heart rate and breathing—lowered costs by on average $500 peremployee a year，the researchers found．

“This indicatesthat physical activity behavior. could reduce at least some of the harmfuleffects of excess body fat。and in consequence，help lower the health—care costs，”Wangand colleagues wrote．

第36题：How canemployees help lower the health—care costs？

A．By taking more rest．

B．By eating less．

C．By exercising a little bit．

D．By saving more money
