If you knew exactly when every person was going to die, or require medical care, you could make a killing buying and selling insurance. Nobody knows these things, of course -- the future is hard to predict -- but some people know something about the future that other people don't. This sets up adverse selection: the ability of one party to leverage information another party doesn't have, in order to gain an economic advantage. Economist Amy Finkelstein is an expert in this phenomenon, as well as the usefulness of empirical studies in economic research.

0:00.0 | Hello everyone, welcome to the Mindscape Podcast. |
0:03.2 | I'm your host, Sean Carroll, and today's topic is Insurance Markets. |
0:08.5 | Now I know in the history of Mindscape we've talked about the meaning of life, the fundamental |
0:13.6 | laws of physics, the way that giant philosophical scientific ideas fit together, as well as |
0:19.8 | some more fun arts and cultural kind of topics. |
0:23.3 | Compared to our usual fair, insurance markets seem pretty down to earth, maybe not the sexiest |
0:28.7 | topic depending on what you get interested in. |
0:31.3 | I get that, but let me tell you, when you dig into what an insurance market is and why |
0:38.1 | it might not work, it's fascinating. |
0:40.5 | There's a lot of intellectually interesting things going on here, especially if you care |
0:44.4 | or are interested in the fundamental workings of capitalism and the market. |

1:04.8 | For knowing that if something goes terribly wrong, you'll be able to protect yourself, to |
1:09.4 | cover your debts or whatever it is, depending on the kinds of insurance. |
1:12.8 | So it's already intellectually interesting because it's trading something right now for |
