We investigate dynamic R&D for process innovation in a Cournot duopoly where firms may either undertake independent ventures or form a cartel for cost-reducing R&D investments. By comparing the profit and welfare performances of the two settings in steady state, we show that private and social...

We reassess the respective gains from R&D cooperation and competition in a Cournot duopoly where firms adopt a concave cost-reducing R&D technology. Cooperation, in the form of either a cartel or a joint venture, is always profitable for firms and, contrary to the previous literature on the same...

The seminal paper by Abreu (1986) is revisited to reassess the optimality of one-shot stick-and-carrot punishments. It is shown that there are admissible conditions under which the use of grim trigger strategies with an infinite Nash reversion is more efficient than implementing Abreu’s penal...

The aim of this paper is to investigate a vertically differentiated market served either by a multiproduct monopolist or by duopolists, in which a public authority aiming at increasing the welfare level can choose among two instruments, namely, quality taxation/subsidisation, and minimum quality...

The choice of the roles by firms in a vertically differentiated duopoly is analyzed introducing a preplay stage where firms set the timing of moves, under the alternative assumptions of full or non full market coverage. Under the first, it turns out that the unique subgame perfect equilibrium...
