In the heart of Texas oil country, in downtown Midland, there’s a locally-famous digital sign. Each day it displays the price of crude. In 2008, it displayed $100 a barrel for the first time.

Wilson Fellow for Energy Studies at Rice University’s Baker Institute, joins host Krys Boyd to talk about the collapse of oil futures, what happened to demand, and how problems in the energy sector affect the larger economy.
