unit 9 b卷一、阅读理解athe government may control prices when there is a problem such as rapidly increasing rents or a rise in the cost of living.when the government controls prices，there is no longer a normal relationship between the price of a product and the quantity consumers will buy.government controls may help in an emergency.however，some economists believe that controls can have negative effects over a long period of time.in cities with rent control，the city government sets the maximum rent that a landlord can charge for an apartment.supporters of rent control argue that it protects people who are living in apartments.their rent cannot increase；therefore，they are not in danger of losing their homes.however，the critics say that after a long time，rent control may have negative effects.landlords know that they cannot increase their profits.therefore，they invest in other businesses where they can increase their profits.they do not invest in new buildings which would also be rentcontrolled.as a result，new apartments are not built.many people who need apartments cannot find any.according to the critics，the end result of rent control is a shortage of apartments in the city.some theorists argue that the minimum wage law can cause problems in the same way.the federal government sets the minimum that an employer must pay workers.the minimum helps people who generally look for unskilled，low paying jobs.however，if the minimum is high，employers may hire fewer workers.they will replace workers with machinery.the price，which is the wage that employers want decreases.thus，critics claim，an increase in the minimum wage may cause unemployment.some poor people may find themselves without jobs instead of with jobs at the minimum wage.supporters of the minimum wage say that it helps people keep their dignity.because of the law，workers cannot sell their services for less than the minimum. furthermore，employers cannot force workers to accept jobs at unfair wages.economic theory predicts the results of economic decisions such as decisions about farm production，rent control，and the minimum wage.the predictions may be correct only if“other things are equal”economists do not agree on some of the predictions.they also do not agree on the value of different decisions.some economists support a particular decision while others criticize it.economists do agree，however，that there are no simple answers to economic questions.1there is the possibility that setting maximum rent may_.acause a shortage of apartmentsbworry those who rent apartments as
