Native American obesity and the associated health conditions are generally thought to result in part from a genetic predisposition to overeating fats and carbohydrates, called the “thrifty gene.” Although coined by nutritional scientists, this study maintains the origin of the thrifty gene lies in economics. Apparently harmful overconsumption and addiction constitute economically rational behavior if the increment to current utility from adding to one’s stock of “consumption capital” is greater than the present value of utility lost in the future due to ill health and the costs of withdrawal. Tests of these conditions for such “rational addiction” are conducted using two-stage household production approach. The results obtained by estimating this model in a panel of Native and non-Native supermarket scanner data show that both Natives and non-Natives tend to be inherently forward-looking in their nutrient choices, but Natives tend to have far higher long-run demand elasticities for carbohydrates compared to non-Natives. Consequently, reductions in real food prices over time, primarily among foods that are dense in simple carbohydrates, leads Native Americans to over-consume potentially harmful nutrients relative to their traditional diet.

Maricopa County has experienced remarkable population growth for decades, and will continue to do so. But while expanding metro areas tend to pay close attention to physical infrastructure—diligently budgeting for roads, sewers, schools and the like—there is often a relative lack of attention to meeting the future demands for human services. Relying on the expertise from throughout the College of Public Programs, this report analyzes 12 critically important topics, including children and families, poverty, substance abuse, and Latinos.
