Suppose that gasoline prices increase dramatically this month. Lola commutes 100 miles to work each weekday. Over the next few months, Lola drives less on the weekends to try to save money. Within the year, she sells her home and purchases one only 10 miles from her place of employment. These examples illustrate the importance of
the time horizon in determining the price elasticity of demand.
In a competitive market, the quantity of a product produced and the price of the product are determined by
both buyers and sellers.
Most labor economists believe that the supply of labor is
less elastic than the demand, and, therefore, workers bear most of the burden of the payroll tax.

The quantity demanded of a good is the amount that buyers are
willing and able to purchase.

The demand for ginger ale is price inelastic, so an increase in the price of ginger ale will increase the total revenue of ginger ale producers.
True or False: The law of demand states that, other things equal, when the price of a good rises, the quantity demanded of the good falls, and when the price falls, the quantity demanded rises.
True
True or False: When free markets ration goods with prices, it is both efficient and impersonal.

Last year, Shelley bought 6 pairs of designer jeans when her income was $40,000. This year, her income is $50,000, and she purchased 10 pairs of designer jeans. Holding other factors constant, it follows that Shelley
considers designer jeans to be a normal good.
The price elasticity of demand for a good measures the willingness of
consumers to buy less of the good as price rises.

A supply curve slopes upward because
an increase in price gives producers an incentive to supply a larger quantity.

can be used to predict the impact on the economy of various events and policies.
