Recently, the state of Washington embarked on an ambitious new plan to combat climate change. Taking a page from economics textbooks, the state instituted a statewide "cap and trade" system for carbon emissions. The state establishes a cap on the total amount of carbon pollution it is willing to allow each year, and then gives away or auctions off carbon emission permits that add up to that total. Companies can then trade those permits on the open market. Economists love cap and trade plans because they establish a limit on carbon emissions while letting the market find the most efficient way for decarbonization to occur. But cap and trade has had a hard time catching on, especially in the U.S. The stakes are high for Washington's new plan. If it succeeds, it could convince other states to implement their own versions, but if it fails, it might serve as a cautionary tale. On today's show, we take a look at how Washington's grand experiment with cap and trade is faring. This episode was hosted by Keith Romer and Kenny Malone.

(Note: A version of this episode originally ran in 2016.) Back in 2016, things were pretty bad in Venezuela. Grocery stores didn't have enough food. Hospitals didn't have basic supplies, like gauze. Child mortality was spiking. Businesses were shuttering. It's one of the epic economic collapses of our time. And it was totally avoidable. Venezuela used to be a relatively rich country. It has just about all the economic advantages a country could ask for: Beautiful beaches and mountains ready for tourism, fertile land good for farming, an educated population, and oil, lots and lots of oil. But during the boom years, the Venezuelan government made some choices that add up to an economic time bomb. Today on the show, we have an economic horror story about a country that made all the wrong decisions with its oil money. It's a window into the fundamental way that money works and how when you try to control it, you can lose everything. Then, an update on Venezuela today. How it went from a downward spiral, to a tentative economic stabilization... amidst political upheaval. This original episode is hosted by Robert Smith and Noel King. It was produced by Nick Fountain and Sally Helm. Today's update was hosted by Amanda Aronczyk, produced by Sean Saldana, fact checked by Sierra Juarez, and engineered by Neal Rauch.
