Interesting audio

From VoxEU.org comes a couple of interesting interviews. First, Alvin Roth of Harvard University talks to Romesh Vaitilingam about his Journal of Economic Perspectives paper on repugnance as a constraint on markets; and his work designing markets for kidney exchange, mechanisms for school choice in New York and Boston, and efficient systems for getting doctors and economists into their first jobs.

Second, Justin Wolfers of the University of Pennsylvania’s Wharton School talks to Romesh Vaitilingam about prediction markets – where they come from; their use in election campaigns and corporate decision-making; how well they perform compared with alternative ways of aggregating information (such as opinion polls or staff meetings); how they can best be designed; and prospects for their application to such areas as geopolitical risks and the spread of disease.
