2017, Christopher Knittel, "The Economics and Politics of Greenhouse Gas Abatement"

There is broad consensus among economists that the most efficient way to reduce greenhouse gases is to put a price on carbon emissions, according to Christopher Knittel of MIT, a research associate in the NBER’s Environment and Energy Economics Program. So why does government policy often rely on other strategies, such as requiring use of biofuels. Knittel discusses research on the costs and benefits of such strategies in the video above.
