Ambulatory Surgery Centers (ASCs) are small (typically physician owned) healthcare facilities that specialize in performing outpatient surgeries and therefore compete against hospitals for patients. Physicians who own ASCs could potentially treat their most profitable patients at their ASCs and...

This essay explores the relationship between commerce and culture in the context of the recent debate over the social effect of Wal-Mart. In spite of much public debate, little is known about how Wal-Mart affects values. Using data collected from multiple sources, we show there is little...

We propose a new method for using validation data to correct self-reported weight and height in surveys that do not measure respondents. The standard correction in prior research regresses actual measures on reported values using an external validation dataset, and then uses the estimated...

Prior research shows that 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...

We investigate the predictive power of survey-elicited time preferences using a representative sample of US residents. In regressions controlling for demographics and risk preferences, we show that the discount factor elicited from choice experiments using multiple price lists and real payments...

We propose a new method for using validation data to correct self-reported weight and height in surveys that do not weigh and measure respondents. The standard correction from prior research regresses actual measures on reported values using an external validation dataset, and then uses the...

Hospital administrators have expressed concern that ambulatory surgical centers (ASCs) lower the profitability of hospitals' outpatient departments by reducing their volume and cherry picking their most profitable patients. This could lead to welfare losses by causing hospitals to reduce their...

Research attributes much of the rise in obesity to technological progress reducing the cost of food consumption. We examine this hypothesis in the context of Walmart Supercenters, whose advancements in retail logistics have translated to substantial reductions in food prices. Using data from the...

Additional work hours may lead to weight gain by decreasing exercise, causing substitution from meals prepared at home to fast food and pre-prepared processed food, or reducing sleep. Substitution toward unhealthy convenience foods could also influence the weight of one's spouse and children,...
