Airfares are determined by both intertemporal price discrimination and dynamic adjustment to stochastic demand. I estimate a model of dynamic airline pricing accounting for both forces with new flight-level data. With model estimates, I disentangle key interactions between the arrival pattern of consumer types and remaining capacity under stochastic demand. I show that the forces are complement...

Most studies suggest that environmental taxes are regressive, and thus are unattractive policy options. We consider the distributional effects of a gasoline tax increase using three welfare measures and under three scenarios for gas tax revenue use. To incorporate behavioral responses we use Consumer Expenditure Survey data to estimate a consumer demand system that includes gasoline, other good...

OBJECTIVES/HYPOTHESIS Head and neck burns (HNBs) engender serious sequelae including airway edema, speech/swallowing dysfunction, sensory deficits, and scarring/disfigurement, often requiring significant reconstructive surgery. We used a nationally representative resource to estimate the number of visits to emergency departments (EDs), analyze burn types and demographic patterns, and identify s...

BACKGROUND Uncertainty exists about the performance of the Framingham risk score when applied in different populations. OBJECTIVE We assessed calibration of the Framingham risk score (ie, relationship between predicted and observed coronary event rates) in US and non-US populations free of cardiovascular disease. METHODS We reviewed studies that evaluated the performance of the Framingham r...

Travel cost and contingent valuation methods are applied to the problem of estimating the potential consumer surpltrs avai!abfe to international nature tourists from a rain forest conservation project in Madagascar. Data are derived from srrrveys of nature tourists in Madagascar and international, nature tolrrism professionals in the U.S. and Europe. Typical trip travel cost models are used to ...

We use the voluntary adoption of the NuVal shelf nutrition labels by a grocery retailer to estimate the value of these labels to shoppers in the yogurt category. Using an incomplete quadratic almost ideal demand system to represent consumer demand, we found a statistically significant positive effect of these shelf labels on demand for yogurt with above-average NuVal scores. The coefficients on...

Delivering ‘relevant’ advertisements to consumers carrying mobile devices is regarded by many as one of the most promising mobile business opportunities. The relevance of a mobile ad depends on at least two factors: (1) the proximity of the mobile consumer to the product or service being advertised, and (2) the match between the product or service and the interest of the mobile consumer. The in...

To facilitate online consumer decision making, a number of e-commerce businesses are augmenting their Web site features. The Web-based decision support for consumers is often provided by eliciting consumer preferences directly or indirectly to generate a set of product recommendations. The software that captures consumer preferences and provides recommendations is called a Web-based decision su...
