Abstract

We test whether asking individuals to donate blood leads to a persistent change in behavior, and examine the underlying mechanism. In a field experiment, we randomize a phone call, asking blood donors to turn out, and follow them over up to 18 months. We observe significant behavioral persistence for at least one year. We use naturally occurring rainfall as a second instrument for donor turnout to test whether behavioral persistence is due to habit formation (Stigler and Becker, 1977) or a persistent increase in motivation independent of past donation. Our results strongly favor habit formation as the underlying mechanism.
