This paper introduces price-dependent individual demand into the circular city model of product differentiation. We show that for any finite number of firms, a unique symmetric price equilibrium exists provided that demand functions are not "too" convex. As in the case of unit demand, the number...

This paper revisits the optimal entry decision in a differentiated product market where customer demand is price-sensitive and depends on a per-unit transport cost. We show that too few firms may enter for high entry cost and high transport cost compared to the socially optimal outcome.

We conduct a laboratory experiment that tests two fundamental predictions unique to salience theory. If an agent purchases one of two vertically differentiated products, salience theory makes the following two distinct predictions. First, it hypothesizes that a higher expected price level for...
