A while back I blogged about work using active choice and enhanced active choice to get people to get flu shots and prescription refills. The basic idea here is that relatively small modifications to the way a choice is presented can have large impacts on the take-up of a program. This seemed useful in the context of many of our training programs– attendance rates averaged 65 percent in a review of business training programs I did with Chris Woodruff. Therefore for an ongoing evaluation of the GET AHEAD business training program in Kenya, we decided to test out this approach.

Standard economic theory would suggest that a one-time infusion of cash should have at most a temporary effect on business profitability – over time, individuals facing high returns should be able to re-invest business profits and bit-by-bit bootstrap themselves up to the steady-state size.
