Uitkomstmaten
Primaire uitkomstmaten
- difference in total calories (kcal) purchased between each tax-condition and the control condition.
Achtergrond van het onderzoek
Research into the effectiveness of pricing interventions and especially tax measures is scarce. Evidence thus far, indicates price as an important factor in food choice. In addition, energy-dense foods tend to be cheaper and more healthful foods tend to be more expensive. Furthermore, the evidence points in the direction of taxing unhealthy foods as a better strategy to limit energy intake than subsidizing healthy food. An RCT will be conducted with 3 different taxing conditions (taxing levels will be set on 25% in all conditions) and a control group will be conducted.
Doel van het onderzoek
The hypothesis is that less calories are purchased in the food tax conditions compared to the control condition
