  Baseline

Secondary Outcomes (1)

• Nutrient density of purchased foods

  Baseline

Study Arms (2)

Own-Price Elasticity

OTHER

The price of eggs will vary (own-price elasticity) while the price of other foods in the "mock" grocery store will remain constant.

Other: Own-Price Elasticity

Cross-Price Elasticity

OTHER

The eggs will remain constant while the price of other foods in the "mock" grocery store will vary (cross-price elasticity).

Other: Cross-Price Elasticity

Interventions

Own-Price Elasticity OTHER

The price of eggs will be 75%, 100%, or 125% of the reference price, but the price of other foods will remain the same.

Own-Price Elasticity

Cross-Price Elasticity OTHER

The price of eggs will remain the same, but the price of other foods will be 75%, 100%, or 125% of the reference price.
