Junk Food Tax More Effective than Good Food Discounts

by Andrea Hill on February 26, 2010

Are incentives insufficient to encourage healthy eating? A recent study by researchers at the University of Buffalo in New York seems to indicate that’s the case.

Participants in the study were given a budget to shop for their family. In cases where the price of junk food was raised, healthier options were selected as an alternative. This would make sense: there is incentive to purchase the healthier, more economical options.

Yet there was a disturbing outcome when the prices of the healthy food was lowered: the mothers ‘treated’ their family by actually purchasing more junk food with the money they were saving.

Obviously, this study is tied to the fact that the mothers were given a particular budget, and therefore could have simply been aiming to spend the entire amount. But it begs the question of barriers: are disincentives more powerful than incentives?
