A new study finds that a modest financial reward increases children’s consumption during school lunch by 80 percent. The study looked at whether small rewards might encourage kids to eat up, thereby cutting waste and improving nutrition. In separate weeklong experiments conducted in 15 schools, the researchers offered a nickel, a quarter, or a raffle ticket to kids for each serving of fruit or vegetables they consumed. In each case, the kids ate significantly more, and overall waste was reduced by about one-third. “Our results indicate that small incentives can dramatically increase fruit and vegetable consumption during school lunch. Incentives also increase the cost effectiveness of the money schools are already spending on fruits and vegetables by increasing the fraction of those items that actually get consumed,” says co-author Joseph Price, a professor if economics at Brigham Young.
