From the episode description:
We all like games don’t we? But in order to win games you need the best strategy and there is one economist who is synonymous with games and more specifically ‘game theory’. You might know him from the award winning film ‘A Beautiful Mind’ but there is so much more to know about John Nash Jr. and the Economics in Ten team want to share that with you. Along the way you will find out the best way to win ‘Rock, Paper, Scissors’, discover the huge cost (or benefit) of the nuclear arms race and what’s the market rate for a Nobel Prize medal at auction.
