We model comparative advertising as brands pushing up own brand perception and pulling down the brand image of targeted rivals. We watched all TV advertisements for OTC analgesics 2001-2005 to construct matrices of rival targeting and estimate the structural model. These attack matrices identify...

This paper analyses a model of vertical product differentiation with one incumbent and one entrant firm. It is shown that if firms can produce only one quality level welfare in this entry game can be lower than in monopoly. This is the case if qualities are strategic complements because the...

In this paper we present an experiment in which we test the effects of sequential entry on the stability of collusion in oligopoly markets. Theoretical as well as experimental research suggests that a larger number of firms in an industry makes collusion harder to sustain. In this study, we...

This paper presents a model of collusion in vertically differentiated industries where firms have the option to make their products distinguishable to consumers by attaching a brand. We show that if consumers’ preferences are linear in the quality dimension and their beliefs satisfy a standard...

This paper analyses the dynamics of a Cournot duopoly under cross-ownership participation when players have heterogeneous, i.e. bounded rational and naïve, expectations. We find that when the shareholder that owns firm also holds a percentage of firm , the parametric stability region of the...

The impact that competition exerts on the incentives of firms to pass through reductions in their marginal costs is an important consideration in assessing the performance of alternate market structures. This paper examines the role of product differentiation on firm-specific and industry-wide...

When there is significant overlap in potential partner airlines' route networks, policymakers have expressed concern that an alliance between such airlines may facilitate collusion on price and/or service levels in the partners' overlapping markets. The contribution of our paper is to put...

It is usually believed that higher competition, implying more active firms, benefits consumers. We show that this may not be the case in an industry with asymmetric cost firms. A rise in the number of more cost inefficient firms makes the consumers worse-off in the presence of a welfare...

Analysts of air travel markets, which include antitrust authorities, are interested in understanding the extent to which the presence of intermediate stop(s) products influences the pricing of nonstop products. This paper uses a structural econometric model to investigate the potential pricing...

This paper develops a model of successive oligopolies with endogenous market entry, allowing for varying degrees of product differentiation and entry costs in both markets. Our analysis shows that the downstream conditions dominate the overall profitability of the two-tier structure while the...
