Nuclear energy is economic and does not emit CO2 but has two central setbacks. First, it has not been yet implemented an efficient method of disposing the spent fuel. Second, the reactors’ complexity is expensive and turns possible the occurrence of accidents. In this paper, first I propose a...

This paper studies the role of uncertainty in merger control and in merger decisions. In a Cournot setting, we consider that mergers may give rise to uncertain endogenous efficiency gains and that every merger has to be submitted for approval to the Antitrust Authority (AA). We assume that both...

This paper studies a non-degenerate price distribution for the homogeneous good within a model of endogenous directed technical change. A probability density function is analytically derived and shown to be related to the technology and innovation parameters of the model.

In this paper we compare two instruments of access price regulation, cost-based and retail-minus, with the full deregulation hypothesis. We consider an upstream monopolist firm that sells a vital input to an independent firm and to a subsidiary firm in the downstream market. We conclude that the...

This paper analyzes the impact of vertical integration on the static and dynamic stability of downstream incomplete collusion. It is shown that a vertical merger between an upstream firm and a downstream cartel or fringe firm promotes downstream collusion, under certain conditions on the market...

The role of multinational firms in the world economy is widely recognized. Multinationals’ activities produce various effects in the host countries, particularly in areas such as: economic growth, technology and innovatory capacity, employment, market structure, performance and business...

We characterize collusion sustainability in markets where demand growth may trigger the entry of a new firm whose efficiency may be different from the efficiency of the incumbents. We find that the profit-sharing rule that firms adopt to divide the cartel profit after entry is a key determinant...

We propose a profit-sharing rule that maximizes sustainability of cartel agreements. This rule is such that the critical discount factor is the same for all the firms. If a cartel applies this rule, then asymmetries among firms may not hinder collusion (contrarily to the typical finding in the...

This paper proposes a general framework to study the sustainability of collusion in markets where demand growth (although deterministic) is not restricted to occur at a constant rate and may trigger future entry. It is shown that, typically, entry occurs later along the collusive path than along...

In a two-sided market duopoly, we investigate the effects of delegating long run restrictive and unrestrictive decisions to managers by the platforms' owners, the effects of the platforms' ownership establishing long run decisions without managers and the impacts of asymmetric regimes between...
