Abstract | A randomized experiment that measures the impact of a social policy in a sample of the population reveals whether the policy will work on average with universal application. An experiment that includes only the subset of the population that volunteers for the intervention generates narrower "proof-of-concept" evidence of whether the policy can work for motivated individuals. Both forms of learning carry value, yet evaluations rarely combine the two designs. The U.S. Social Security Administration conducted an exception, the Benefit Offset National Demonstration (BOND). This article uses BOND to examine the statistical power implications and potential gains in policy learning--relative to costs--from combining volunteer and population-representative experiments. It finds that minimum detectable effects of volunteer experiments rise little when one adds a population-representative experiment, but those of a population-representative experiment double or quadruple with the addition of a volunteer experiment.
