Episode 4

The premier comedy-economics hybrid is tackling the big, competing theories of Macro Economics.

These are little short of religions to their proponents, and the figures who devised them dominate the intellectual landscape in a way that mere politicians can only dream of. These are the Big Beards, the Glinting Eyes, the Bristling Moustaches and Eyebrows of "Worldly Philosophy" and their insights, calculations and hallucinations remain as contentious today as they were when first inked into place.

In this series Simon Evans, with the help of Undercover Economist, Tim Harford will advance through the modern industrial era using three great beacons as their guide - Adam Smith, Karl Marx and John Maynard Keynes - and reflect on how they continue to shape our world today.

After three episodes focusing on the lives and theories of Adam Smith, Karl Marx and John Maynard Keynes, it's time for Simon and Tim to attempt synthesis and see how these three economic superbrains can help us out of our current economic predicament.
