Who doesn’t love kicking back after work with a snack and a good show? Everyone loves some free time . . . but, of course, time isn’t free! In the past 10 years, ridesharing services like Uber have become wildly popular. People who need to get from A to B value the ability to connect with a driver rapidly, rather than waiting for a scarce taxicab. And ordinary people (with a nice enough car) can earn a few extra bucks giving rides, working as little or as much as they please. Today, an estimated 2 million people drive for Uber, often evenings and weekends after they’re finished the day at a full-time job. Explain how the growth of Uber reflects the way in which ridesharing has altered the opportunity cost of leisure.
