Summary

What exactly is a carbon price, and how does it work? To prepare for a new episode about climate economics, we’re re-airing this season one episode in which MIT professor Christopher Knittel explains economists’ favorite tool for addressing climate change. Professor Knittel also returns for a special update on big developments in the world of carbon pricing, from Canada, China, and the European Union.
