Standard models in economics stress the role of intelligent agents who maximize utility. However, there may be situations where, for some purposes, constraints imposed by market institutions dominate intelligent agent behavior. We use data from the London Stock Exchange to test a simple model in...

We analyze two- and three-dimensional variants of Hotelling's model of differentiated products. In our setup, consumers can place different importance on each product attribute; this is measured by a weight in the disutility of distance in each dimension. Two firms play a two-stage game; they...

Theoretical models of multidimensional product differentiation predict that in duopoly firms differentiate maximally along one dimension and minimally along the other dimensions. We experimentally reproduce a market in which firms can differentiate their products along two horizontal dimensions....
