shift to the right.

households' income.

When the percentage change in quantity demanded is less than the percentage change in price that brought it about, demand is said to be

inelastic.

In command economies, economic behavior is

largely determined by a central authority.

To say that the demand curve for movies is negatively sloped means that

less quantity will be demanded at higher prices.

f the total expenditure on automobiles increases when the price of automobiles rises, the price elasticity of demand for automobiles is

less than one (demand is inelastic).

The price elasticity of demand for a product tends to be greater the

more close substitutes for it there are.

A theory

must be judged on its ability to explain and predict real-world phenomena

If per capita income increases by 10 percent and household expenditures on leather coats increase by 15 percent, one can conclude that the price elasticity of demand for leather coats is

not determinable from the information given.

positive

If the legal beer-drinking age is raised by two years, the changes to the equilibrium price and quantity of beer will be such that

price falls, quantity falls.

Consider the law of demand. Other things being equal, the quantity of beer demanded will be greater if the

price of beer is lower.

Excess demand is the same thing as

quantity demanded minus quantity supplied.

The price elasticity of demand measures the responsiveness of

quantity demanded to changes in the price.

For an inferior good, the quantity demanded

rises when income falls.
