We develop a model with many advertisers (products) and many advertising markets (media). Each advertiser sells to a different segment of consumers, and each medium is targeting a different audience. We characterize the competitive equilibrium in the advertising markets and evaluate the implications of targeting. An increase in targeting leads to an(More)
Following FCC pressure to end bill shock, cellular carriers now alert customers when they exceed usage allowances. We estimate a model of plan choice, usage, and learning using a 2002–2004 panel of cellular bills. Accounting for firm price adjustment, we predict that implementing alerts in 2002–2004 would have lowered average annual consumer welfare by $33.(More)
The internet has made it easier for customers to find and buy a wide variety of products. This may lead to a “long tail” effect as more customers buy low-volume products. However, the internet has also made it easier for customers to find out which products are most popular. This could lead to a “steep tail” effect as customers flock towards the most(More)
Rodent models of cognitive aging routinely use spatial performance on the water maze to characterize medial temporal lobe integrity. Water maze performance is dependent upon this system and, as in the aged human population, individual differences in learning abilities are reliably observed among spatially characterized aged rats. However, unlike human aging(More)
The effectiveness of parks as management regimes is hotly contested. Much of the current discussion centered around comparisons of management regimes can be traced to a dearth of cross-site quantitative evaluations. Remote sensing provides a particularly effective tool for this purpose, yet analysis of remotely sensed data requires fieldwork to interpret(More)
This study evaluates the relationship between landscape accessibility and land cover change in Western Honduras, and demonstrates how these relationships are influenced by social and economic processes of land use change in the region. The study area presents a complex mosaic of land cover change processes that involve approximately equal amounts of(More)
Patent assertion entities, sometimes known as ‘patent trolls,’ do not manufacture goods themselves but profit from licensing agreements that they often enforce via the threat of litigation. This paper explores empirically how litigation by one such patent troll affected the sales of medical imaging technology. It finds evidence that relative to similar(More)
A significant challenge in the assessment of forest management outcomes is the limited ability to compare forest conditions quantitatively across ecological zones. We propose an approach for comparing different forest types through the use of reference forests. We tested our idea by drawing a sample of 42 forests from the Midwest USA, Mexico, Guatemala,(More)
