Since the late 1970s, the number of obese adults in the United States has grown by over 50 percent. This paper examines the factors that may be responsible for this rapidly increasing prevalence rate. To study the determinants of adult obesity and related outcomes, we employ micro-level data...

As economic expansions raise employment and wages, associated shifts in income and time constraints would be expected to also impact individuals' health. This study utilizes information from the Behavioral Risk Factor Surveillance System (1990-2007) to explore the relationship between the risk...

We study the impact of mandatory calorie posting on consumers' purchase decisions, using detailed data from Starbucks. We find that average calories per transaction falls by 6%. The effect is almost entirely related to changes in consumers' food choices--there is almost no change in purchases of...

How do peers influence the impact of incentives? Despite much work on incentives, little is known about the spillover effects of incentives. We investigate two mechanisms by which these effects can occur: through peers' actions and peers' incentives. In a field experiment on snack choice (grapes...

Healthy food choices are a canonical example used to illustrate the importance of time preferences in behavioral economics. However, the literature lacks a direct demonstration that they are well-predicted by incentivized time preference measures. We offer direct evidence by combining a novel,...

Growing consumption of increasingly less expensive food, and especially "fast food", has been cited as a potential cause of increasing rate of obesity in the United States over the past several decades. Because the real minimum wage in the United States has declined by as much as half over...

There are several ways to measure fatness and obesity, each with its own strengths and weaknesses. The primary measure for tracking the prevalence of obesity has historically been body mass index (BMI). This paper compares long-run trends in the prevalence of obesity when obesity is defined...

In our opinion, the trend in the BMI values of US children has not been estimated accurately. We use five models to estimate the BMI trends of non-Hispanic US-born black and white children and adolescents ages 2-19 born 1941-2006 on the basis of all NHES and NHANES data sets. We also use some...

The prevalence of obesity has increased rapidly since the mid-1970s, following a period of relative stability. This study examines past patterns and projects future prevalence rates of obesity and severe obesity among US adults through 2020. Trends in body mass index (BMI), overweight (BMI 25),...

We study the causes of "nutritional inequality": why the wealthy tend to eat more healthfully than the poor in the U.S. Using event study designs exploiting supermarket entry and households' moves to healthier neighborhoods, we reject that neighborhood environments have meaningful effects on...
