We use a unique dataset that combines information on advertising by subprime lenders and mortgages originated by them from 2002 to 2007 to study the relationship between advertising and the nature of mortgages obtained by consumers. We exploit the richness of our data and measure the relative...

The internet has dramatically reduced the cost of varying prices, displays and information provided to consumers, facilitating both active and passive experimentation. We document the prevalence of targeted pricing and auction design variation on eBay, and identify hundreds of thousands of...

The 2010 Department of Justice and Federal Trade Commission Horizontal Merger Guidelines lay out a new standard for assessing proposed mergers in markets with differentiated products. This new standard is based on a measure of ``upward pricing pressure,'' (UPP) and the calculation of a ``gross...

A model is considered where firms internalize the regret costs that consumers experience when they see an unexpected price change. Regret costs are assumed to be increasing in the size of price changes and this can explain why the size of price increases is less sensitive to inflation than in...

This paper starts by discussing consumers' cognitive and emotional reaction to posted prices. Cognitively, some consumers do not appear to make effective use of price information to maximize their consumption-based utility. Emotionally, prices can induce regret and anger among consumers. The...

We propose a method for aggregating prices when retailers use periodic sales to price-discriminate amongst heterogeneous customers. To do so, we introduce a model in which Loyal customers buy one brand and do not strategically time purchases, while Bargain Hunters always pay the lowest price...

We use a large dataset on retail pricing to document that a sizeable portion of the cross-sectional variation in the price at which the same good trades in the same period and in the same market is due to the fact that stores that are, on average, equally expensive set persistently different...

Bayesian consumers infer that hidden add-on prices (e.g. the cost of ink for a printer) are likely to be high prices. If consumers are Bayesian, firms will not shroud information in equilibrium. However, shrouding may occur in an economy with some myopic (or unaware) consumers. Such shrouding...

Mediating transactions through the Internet removes important cues that salespeople can use to assess a consumer's willingness to pay. We analyze whether dealers' difficulty in identifying consumer characteristics on the Internet and consumers' ease in finding information affects equilibrium...

The safety of the commercial airline industry has attracted considerable public attention and debate since economic deregulation of the industry in 1978. These concerns have energized economic research on three aspects of airline safety. First, has the level of airline safety declined since...
