The field of economics can study more than the workings of economies or businesses, it can also help explore human behavior in how it reacts to incentives. Economist Steven D. Levitt and journalist Stephen J. Dubner host an anthology of documentaries that examines how people react to opportunities to gain, wittingly or otherwise. The subjects include the possible role a person's name has for their success in life, why there is so much cheating in an honor bound sport like sumo wrestling, what helped reduce crime in the USA in the 1990s onward and we follow an school experiment to see if cash prizes can encourage struggling students to improve academically.—Kenneth Chisholm ([email protected])
