Economist and journalist Allison Schrager visited a legal brothel, chased celebrities with the paparazzi, attended conferences with surfers, and interviewed high-ranking military generals, all to better understand the nature of risk. In her book, “An Economist Walks Into A Brothel,” Schrager explores how people manage risk outside the world of economics and finance and considers the most interesting lessons that can be learned from people in some of the riskiest professions.
