(You can download/subscribe at iTunes, get the RSS feed, listen live via the media player above, or read the transcript here.) Anyone who has been around long enough can observe that hitchhiking numbers have plummeted. So Freakonomics Radio set out to find the numbers on thumbers and found ... well, not much. Apparently hitchhiking never qualified as an important-enough mode of the transportation sector to generate heavy-duty empirical research.  So we take a whack at explaining the phenomenon. Here's Levitt's take: LEVITT: Hitchhiking is a classic example of what an economist would call a matching market, where there&#x2019;s a person who wants a ride, and there&#x2019;s a person who&#x2019;s willing to give a ride. There was some sort of equilibrium in which there was a set of people who wanted to hitchhike, and there was a set of people who were willing to pick them up. And somehow that equilibrium got destroyed. So the question is what happened to the equilibrium?</description></oembed>
