Tim Harford's new Radio 4 series Pop-Up Economics tells stories about fascinating people and ideas in economics.
The economist returns to a store in London's Regent Street to tell an audience the story of Thomas Schelling, an economist who helped America and the Soviet Union to avoid nuclear war.
Here, we hear how Schelling applied the simple concepts of John von Neumann's game theory to help form the US's nuclear deterrent strategy during the cold war.
