Welcome to The Bryan Caplan Collection, where you can predict the outcomes of economist Bryan Caplan's wagers on topics like economic growth, climate change, college attendance, and more.

Bryan Caplan is an economics professor at George Mason University, a New York Times bestselling author writing at Bet On It, and he maintains a public inventory of his bets with academics, researchers, and pundits on a wide variety of topics.

Caplan has logged more than 20 public bets going back nearly two decades and has yet to lose a single one. Still, he concedes his streak is unlikely to continue much longer and wrote in 2020: "Will I lose eventually? Almost surely, because I’m going to keep betting."

Thank you to Bryan Caplan for his involvement in this question series.
