This paper studies the tendency to use negative ads. For this purpose we focus on an interesting industry (political campaigns) and an intriguing empirical regularity (the tendency to “go negative” is higher in close races). We present a model of electoral competition in which ads inform...

Brands and word-of-mouth (WOM) are cornerstones of marketing, yet, their relationship was largely ignored. In order to explore this relationship we present a theoretical framework whose fundamentals are consumers and what stimulates them to engage in WOM. It argues that consumers spread the word...

One of the most significant and robust characteristics of decision making is persistence. An example of this is brand loyalty -- the repeat purchase of new products of the same brand.

We present an empirical study of spatial competition and a methodology to estimate demand for products with unobservable characteristics. Using panel data, we estimate a discrete choice model with latent product attributes and unobserved heterogenous consumer preferences. Our application of the...

Internet news and search sites often excerpt content from and link to competing news outlets. On the one hand, providing outbound links can make the linking site more attractive, even to the point of stealing traffic from the linked sites. Regulatory policy, such as the European Union’s...
