The "spokes model" takes the name from its graphical visualisation that resembles the spokes of a bike's wheel. It describes a market as a collection of spokes, joining at a common centre, where consumers are located. Firms may be situated at the extreme of these spokes, at the interior of the...

We rationalize several facts emerging from the recent empirical research on cooperatives owned by workers (workers' firms, WF) as: the concern of WFs for employment; the interplay between membership and workplace safeguard within WFs; the different reaction to shocks between WFs and...

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 propose a new model of mixed oligopoly where a workers' cooperative firms competes with a number of profit maximising companies. Building upon a large empirical evidence, we innovate as compared to the traditional literature on the objective function of the cooperative; moreover, its...

Two of the main pillars of the EU waste collection policy are the Proximity Principle and Self-Sufficiency Principle. According to those, waste should be disposed as close as possible to where it has been produced. The effect of such provision is to increase the market power of local disposers,...

Data brokers collect, manage, and sell customer data. We propose a simple model, in which data brokers sell data to downstream firms. We characterise the optimal strategy of data brokers and highlight the role played by the data structure for co-opetition. If data are “sub-additive”, with...

The unprecedented access of firms to consumer level data not only facilitates more precisely targeted individual pricing but also alters firms’ strategic incentives. We show that exclusive access to a list of consumers can provide incentives for a firm to endogenously assume the price...

Behaviour-based price discrimination (BBPD) is typically analysed in a framework characterised by perfectly inelastic demand. This paper provides a first assessment of the role of demand elasticity on the profit, consumer and welfare effects of BBPD. We show that the demand expansion effect,...
