If the price of a movie ticket increases by 4 percent and the quantity of movies demanded falls by 2 percent, the price elasticity of demand is

0.5. %ΔD/% ΔP = 2%/4% = -½

The University of South Dakota just lowered the price of its season football tickets from $350.00 to $300.00. As a result, there was an increase in the number of season tickets purchased from 430 to 470. Rounding to two decimal places, the price elasticity of demand for season tickets equals

0.58. %ΔD/% ΔP = [(Q1-Q2)/QAVE] / [(P1-P2)/PAVE] = [(430-470)/450] / [(350-300)/325] = -0.57777

A 10 percent increase in income increases the quantity of orange juice demanded from 19,200 to 20,800 gallons. The income elasticity of demand for orange juice is

supply curve of good B leftward.

During the last decade, the price of a computer fell every year and the quantity sold increased every year. This experience suggests that the

supply curve shifted rightward

If the price of oil is $60 per barrel, the quantity of oil supplied is 70 million barrels per day. If the price is $40 per barrel, the quantity of oil supplied is 69 million barrels per day. This implies that the

supply of oil is inelastic. %ΔD/% ΔP = [(Q1-Q2)/QAVE] / [(P1-P2)/PAVE] = [(70-69)/69.5] / [(60-40)/50] = 0.03597

Comparative advantage is

the ability to perform an activity at a lower opportunity cost than anyone else
