Detaljeret beskrivelse
In this study, 239 loyalty card shoppers were recruited at Hannaford grocery stores to participate in a study in which a 10% price difference between nutritious and less nutritious foods was introduced.
and then framed as a subsidy, tax, or a combination of a tax and subsidy.
To determine whether or not the framing of the price difference influenced purchasing behavior, the difference was framed as a subsidy on nutritious foods, a tax on less nutritious foods, and a combination of a tax and subsidy on less nutritious and nutritious foods, respectively.
