ts 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(紧急情况).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(房主)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(批评者)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 rent-controlled.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.Economic theory predicts the results of economic decisions such as decisions about rent control，price 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.
