Experimental: Own-Price Elasticity
The price of fruit will vary (own-price elasticity) while the price of all other foods in the "mock" grocery store will remain constant.
Other: Own-Price Elasticity
The price of fruit will be 75%, 100%, or 125% of the reference price, but the price of other foods will remain the same.
Experimental: Cross-Price Elasticity
The price of fruit will remain constant while the price of other foods in the "mock" grocery store will vary (cross-price elasticity).
Other: Cross-Price Elasticity
The price of fruit will remain the same, but the price of other foods will be 75%, 100%, or 125% of the reference price.
- Price elasticity of fruit [ Time Frame: Baseline ]Percent change in the amount of fruit purchased (gram weight) for every percent change in the price of a given food.
- Nutrient density of purchased foods [ Time Frame: Baseline ]Ratio of low nutrient-dense food purchases to high nutrient-dense food purchases
