Abstract

Native American obesity is hypothesized to result from three potential causes: (1) a genetic predisposition, or the "thrifty gene,"(2) a rational addiction to nutrients, and (3) dietary adjustment costs. These hypotheses are tested using a two-stage household production approach and scanner data from a panel of Native and non-Native supermarkets. Nutrient intake for both groups is strongly influenced by adjustment costs. Native Americans tend to place higher implicit valuations on protein relative to fats and carbohydrates compared to non-Natives. Consequently, reductions in real carbohydrate prices over time may be a cause of high incidence of Native American obesity.
