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...

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...

This article focuses on the location decision of firms when competing in a spatial Cournot duopoly. Our original contribution is that firms are dependent on a natural resource input, which is assumed to be located in one of the extremes of the market, to be able to produce the output sought by...

In spatial competition iuml;B01rms are likely to be uncertain about consumer locations when launching products either because of shifting demographics or of asymmetric information about preferences. Realistically distributions of consumer locations should be allowed to vary over states and need...

In spatial competition firms are likely to be uncertain about demand when launching products either because of shifting demographics or of asymmetric information about preferences. This paper considers two types of prices: those set on prior information and flexible prices which adjust across...

The paper studies indirect network effects in a market composed by two incompatible intermediaries that choose price (short-term issue) in addition to location (long-term issue). The paper first shows that (i) when the network externality is sufficiently weak, only maximum differentiation...

This paper argues that large distance and border effects on trade flows in some industries might be a result of the (explicitly or tacitly) collusive division of geographic markets. A simple spatial oligopoly setting demonstrates how goods can travel shorter distances, or trade between regions...
