Suppose that a city law requires taxi drivers to wear tuxedos. The drivers must pay $10
per week for the tuxedos. Taxicab companies pay their drivers $210 per week. After
paying for the tuxedos, taxi drivers earn $200 per week.
(i) If the law were revised so that taxicab companies, not the drivers, must pay for the
tuxedos, what would happen to the taxi drivers’ earnings?
(ii) If the law were repealed, what would happen to the taxi drivers’ earnings? Be as
specific as possible.
Suppose there are two goods: guns and roses. Also suppose Australia is initially closed
to trade. When international trade is opened, Australia chooses to sell guns and buy
roses in the world markets.
