We study a Hotelling framework in which customers first pay a monopoly platform to enter the market before deciding between two competing services on opposite ends of a Hotelling line. This setup is common when modeling competition in Internet content provision. We find that standard...

We analyze the effects of consumers' limited attention on welfare in a model of horizontal product differentiation. We present a novel approach of modeling limited attention: an attention radius. Each consumer only notices goods that are within her attention radius, i.e., goods that are...

In Hotelling style duopoly location games the product variety (or firm locations) is typically not socially optimal. This occurs because the competitive outcome is driven by the density of consumers at the margin while the socially optimal outcome depends on the whole distribution of consumer...

This paper extends the traditional Hotelling's model of spatial competition by allowing firms to choose the degree of general purposeness of their products before they compete in prices. The degree of general purposeness is approximated by endogenizing the per-unit transportation cost...

We discuss the effect of personalized pricing on profits and welfare in a Hotelling model in which consumers can simultaneously purchase from both firms. As the additional gain from the second purchase increases, personalized pricing is more likely to harm (resp., benefit) consumers (resp.,...

In a spatial competition setting there is usually a non-negative relationship between competition and quality. In this paper we offer a novel mechanism whereby competition leads to lower quality. This mechanism relies on two key assumptions, namely that the providers are motivated and...

We study the effect of competition on quality in markets such as health care, long-term care and education, when providers choose both prices and quality in a setting of spatial competition. We offer a novel mechanism whereby competition leads to lower quality. This mechanism relies on two key...

This paper extends Hotelling's model of price competition with quadratic transportation costs from a line to graphs. I propose an algorithm to calculate firm-level demand for anygiven graph, conditional on prices and firm locations. These graph models of price competitionmay lead to spatial...
