The imposition of universal coverage and uniform pricing constraints, as part of the universalservice obligations, makes the universal service provider less aggressive in the price game when itcompetes with a firm that does not cover the whole set of markets (Valletti et al., 2002). In...

We analyse a (differentiated good) industry where an incumbent firm owns a networkgood (essential input) and faces potential competition in the (downstream) retailmarket. Unlike the traditional approach, we consider a scenario where the decision tocompete or not in the downstream segment is...

In this paper we consider the problem of financing infrastructure when the regulator faces a budget constraint. The optimal budget-constrained mechanism satisfies four properties. The first property is bunching at the top, that is the more efficient firms produce the same quantity. The second...

This article studies the problem of regulating a monopolist with unknown marginal cost. The originality of the paper is to consider that the regulator faces a cash-in-advance constraint. The introduction of such a constraint not only reduces the amount of public good provided but also limits the...

In this paper we consider the problem of regulating an open access essential facility. A vertically integrated firm owns an essential input and operates on the downstream market under the roof of a regulatory mechanism. There is a potential entrant in the downstream market. Both competitors use...

Prosumers are households that are both producers and consumers of electricity. A prosumer has a grid-connected decentralized production unit (DPU) and makes two types of exchanges with the grid: energy imports when the local production is insuffcient to match the local consumption and energy...

in the French urban public transport industry, operations are often delegated and periodically put out for tender. Thus, operators’ incentives to reduce costs come from both profit maximization during the current contract and from the perspective of contract renewal. We construct a dynamic...

This paper analyzes two business practices on the mobile internet market, paid prioritization and zero-rating. Both violate the principle of net neutrality by allowing the internet service provider to discriminate different content types. In recent years these practices have attracted...
