Prior research shows grocery stores reduce prices to compete with Walmart Supercenters. This study finds evidence that the competitive effects of two other big box retailers - Costco and Walmart-owned Sam's Club - are quite different. Using city-level panel grocery price data matched with a...

This paper examines the effect of Walmart Supercenters, which lower food prices and expand food availability, on household and child food insecurity. Our food insecurity-related outcomes come from the 2001-2012 waves of the December Current Population Study Food Security Supplement. Using narrow...

Electronic nicotine delivery systems (ENDS) use among lesbian, gay, bisexual, and questioning (LGBQ) teenagers is over 30 percent higher than among their heterosexual counterparts. Yet little is known about how recent efforts to curb nicotine vaping through ENDS taxes impact sexual minorities....

A growing literature examines the effects of economic variables on obesity, typically focusing on only one or a few factors at a time. We build a more comprehensive economic model of body weight, combining the 1990-2010 Behavioral Risk Factor Surveillance System with 27 state-level variables...

This paper examines the role physical activity plays in determining body mass using data from the American Time Use Survey. Our work is the first to address the measurement error that arises when time use during a single day--rather than average daily time use over an extended period--is used as...
