My research topic involves children as consumers in the food market. I investigate determinants of German children's food preferences and autonomous snack purchase decisions. The research includes incentive-compatible purchase experiments with primary school children as well as a content analysis of the effectiveness of the EU Pledge, a self-regulatory initiative by leading food companies at the European level to restrict television advertising of foods and beverages high in fat, sugar, or salt to children.
