Tim Harford on the Indiana Jones of economics
23 January 2013 Last updated at 09:45 GMT
Tim Harford's new Radio 4 series Pop-Up Economics tells stories about fascinating people and ideas in economics.
Among the stories he tells are those of Al Roth, who created a clearing-house for kidneys, the cold war game theorist Thomas Schelling and Bill Phillips, who he argues was the 'Indiana Jones of economics'.
Phillips worked as a busker, a gold miner and a crocodile hunter before studying at the London School of Economics where he used a system of water pumps and valves to create the first working model of the British economy or indeed of any economy.
