question
In Egypt, in 1970, the Aswan Dam was completed. By preventing the annual flood of the Nile (thereby providing millions of acres of arable land) and by providing electricity, the dam was expected to raise the living standard of the Egyptian people-and it has. However, it has also led to a rise in the water table which causes Egypt's limestone structures, including the pyramids, to absorb more salt water and to suffer serious erosion from crystallized salts. Combined with air pollution and traffic vibration, this erosion is turning the pyramids to dust. Economists analyze this type of problem with the concept of
answer
an externality.

answer
an externality
question
The use of chlorofluorocarbons in refrigerators and air conditioners is alleged to cause the destruction of the ozone layer that surrounds the earth. This layer protects humans from ultraviolet radiation, which causes skin cancer. Industry has been prohibited from using these substances in aerosol cans, but the government has been reluctant to ban their use altogether because of the serious economic consequences. Economists analyze such problems and refer to them as
answer
externalities.
question
Rent control is usually justified on the grounds that it protects moderate- to low-income families from the burden of rapidly rising rents and from eviction if they are unable to pay. It also prevents landlords from reaping windfalls as property values rise. Opponents note that rent controls usually lead to a reduced supply of rental housing and shortages. The proponents of rent controls support them primarily on the grounds of
answer
equality
question
Because there is a trade-off between total output and equality of income distribution
answer
policies designed to equalize distribution may adversely affect the size of output.
question

answer
chosen greater wage inequality for lower unemployment.
question
In contrast to the United States, the European Union has chosen
answer

In the United States, the fact that the gap between the rich and the poor has been increasing is often justified by economists on the grounds that greater
answer
inequality is an undesirable consequence of greater efficiency.
