The unprecedented access of firms to consumer level data facilitates more precisely targeted individual pricing. We study the incentives of a data broker to sell data about a segment of the market to three competing firms. The segment only includes a share of the consumers in the market around...

This paper studies the consequences of product-market competition on firms' decisions to delegate more or fewer decision-making responsibilities to managers. By simultaneously addressing the choice of both competitive actions and organizational design, the paper makes an attempt at bringing...

The unprecedented access of firms to consumer level data facilitates more precisely targeted individual pricing. We study the incentives of a data broker to sell data about a segment of the market to three competing firms. The segment only includes a share of the consumers in the market around...

We develop a framework, extending the conventional duopoly model by replacing the Hotelling line with a simplex in high???dimension spaces, to study the competition and access regulation of multiple networks. We first characterize the competitive equilibrium when the substitutabilities of the...

This paper provides an example that incumbent firms might allow potential entrants to enter a market. The market consists of two sub-markets: a high-end market and a low-end market. (i) If low-quality products are of no value to consumers in the high-end market, (ii) consumers in the low-end...

We investigate a Cournot model with strategic R&D investments wherein efficient low-cost firms compete against less efficient high-cost firms. We find that an increase in the number of high-cost firms can stimulate R&D by the low-cost firms, while it always reduces R&D by the high-cost firms....

This paper derives a Supply Function Equilibrium (SFE) of a pay-as-bid auction, also called discriminatory auction. Such an auction is used in the balancing market for electric power in Britain. For some probability distributions of demand a pure-strategy equilibrium does not exist. If demand...

Producers submit committed supply functions to a procurement auction, e.g. an electricity auction, before the uncertain demand has been realized. In the Supply Function Equilibrium(SFE), every firm chooses the bid maximizing his expected profit given the bids of the competitors. In case of...

We study a market for a homogeneous good in which firms adjust their production decisions on the basis of imitation, learning from own experience, and local experimentation. For any fixed set of firms (more than one), long run behaviour settles on a symmetric marginal-cost pricing equilibrium....

This discussion paper led to an article in <I>Games and Economic Behavior</I> (2012), pp. 120-138.<P> We consider an oligopolistic market where firms compete in price and quality and where consumers are heterogeneous in knowledge: some consumers know both the prices and quality of the products offered,...</p></i>
