In Table 1, we provide pre and post-treatment information about the fruit and vegetable
consumption patterns for each of our school treatment groups. Our key measures are the fraction
of kids who took at least one serving of fruits or vegetables, the fraction of kids who ate at least
one serving of fruits or vegetables, and the fraction of these items that ended up being thrown
away. Among schools that provided an immediate reward, the change in behavior was lowest
when the reward was a nickel (a 15.4 percentage point jump), and was highest when the reward
was a quarter (a 38.4 percentage point jump). The regression results that follow test more
precisely how the response to incentives differed based on nature and timing of the reward.
