We analyze differentiated retail industries where shops engage in two-stage competition with respect to opening hours and prices. We explore the effects of consumers' shopping time flexibility by comparing bi-directional consumers with forward- or backward-oriented consumers, who can either...

We examine incentives of bottleneck facility holders to manipulate access charge accounting in free entry downstream markets. We consider the situation wherein one firm holds an upstream bottleneck facility and new entrants use it at the regulated price (access fee) to provide final products....

Shaked and Sutton (1982) and Gelman and Salop (1983) are best remembered for their neat conclusions: a limited quality or limited capacity is an effective tool to relax competition and facilitate entry in a market. We aim at comparing the respective merits of these two strategic commitments. We...

We investigate the effects of passive backward acquisitions in their efficient upstream supplier on downstream firms' ability to collude in a dynamic game of price competition with homogeneous goods. We find that passive backward acquisitions impede downstream collusion. The main driver of our...

Researchers have recently developed models for determining which market conduct best describes observed data. We apply these techniques from the "new empirical industrial organization" literature to the competitive product line pricing decision, where a firm strategically prices its brands when...

Using a duopoly model with symmetric retailers, we show that retailer strategies regarding opening hours and quality choices of goods vary depending on the cost structure of the quality investment in goods. In the case of the cost remaining constant regardless of the length of opening hours, a...

We modify the vertically differentiated duopoly model by André et al. (2009) replacing Bertrand with Cournot behaviour to show that firms may spontaneously adopt a green technology even in the complete absence of any form of regulation

We extend the analysis carried out by Valletti (2000) by considering an environmental externality in a vertically differentiated duopoly where firms compete à la Cournot with fixed costs of quality improvement.We show that, if the weight of the external effect is high enough, the resulting...

In the framework of a vertically differentiated mixed duopoly, with uncovered market and costless quality choice, we study the existence of a price equilibrium when a welfare-maximizing public firm producing low quality goods competes against a profit-maximizing private firm producing high...
