We analyze firms' location choices in a Hotelling model with two-dimensional consumer heterogeneity, along addresses and transport cost parameters (flexibility). Firms can price discriminate based on perfect data on consumer addresses and (possibly) imperfect data on consumer flexibility. We...

The paper studies a two-stage location-price duopoly game in a disk city with consumer concentration around the city center. When consumers are uniformly distributed over the plane, unconstrained firms locate outside of the city. Consumer concentration, however, induces firms to locate nearer to...

Firms such as hotels, banks, and telecommunication operators offer packages of a base good and services. This paper asks why firms include services in a package ('packaging') and which services are likely to be included. The main argument is that consumers incur a search cost to discover...

The Australian Parliament has passed legislation compelling tobacco products to be sold in “plain packaging”. This paper reviews this legislation and its likely effects on prices, market structure in the tobacco industry and on smoking behaviour. Industry changes following two previous sets...

We consider the presence of first-mover advantage or disadvantage in a duopoly model of product positioning in which firms are symmetric, except for order of entry. We study a generalization of the Hotelling model, in which a consumer's utility from a product depends on the location of product...

Neil Averitt and Robert Lande have for some time been writing about consumer choice as a new paradigm for antitrust. In this comment, I both praise and extend the consumer choice paradigm and provide concrete examples of both cutting edge and familiar antitrust issues where consumer choice can...

A methodology is proposed to estimate structural models of product line competition. This methodology enables researchers to estimate demand systems accounting for the endogeneity of the mix of products available in each market, an issue which is typically ignored in the empirical literature. In...

This chapter focuses on the economic mechanisms at work in recent models of advertising finance in media markets developed around the concept of two-sided markets. The objective is to highlight new and original insights from this approach, and to clarify the conceptual aspects. The chapter first...

This paper examines a common assertion that customers in reward programs become "locked in" as they accumulate credits toward earning a reward. We define a measure of switching costs and use a dynamic structural model of demand in a reward program to illustrate that frequent customers' purchase...

This article analyses the capacity-then-price game for a duopoly market. We add to the literature by explicitly taking product differentiation into account. We study the impact of capacity costs, demand uncertainty, and vertical and horizontal product differentiation on equilibrium capacities,...
