We study cartel stability in a differentiated price-setting duopoly with returns to scale. We show that a cartel may be equally stable in the presence of lower differentiation, provided that the decreasing returns parameter is high. In addition we demonstrate that for a given factor of discount,...

Using the coefficient of cooperation, we analyse the effect of cost asymmetries on collusive agreements when firms are able to coordinate on distinct output levels than the unrestricted joint profit maximization outcome. In this context, we first investigate the extent to which collusive...

In a network industry, this paper investigates the impact of network effects on total pollution under the presence of a union interested to "local" environmental damages (e.g., polluting production processes damaging workers' health and the local environment where workers live). Under monopoly,...

In this paper we characterize optimal punishments with detection lags when the market consists of n oligopolistic firms that compete à la Cournot. It is shown how in the presence of detection lags optimal punishments fail to restore cooperation as long as the number of lags increases. Moreover,...

This paper quantifies the welfare cost of consumption externalities in an endogenous growth model with habit formation. Agent’s utility depends on both current consumption and a reference consumption level determined by economy-wide average past consumption. Although utility may be lower in...

This article depicts a location game in a circular market. The equivalence results between a convex and a concave transport cost are reexamined by assuming an arbitrary length. In contrast to previous research the solution found shows that the equivalence relationship depends on the space...

It is commonly believed that the choice of adopting Corporate Social Responsibility (CSR) behaviours is beyond the scope of profit enhancement. In a unionised oligopoly with centralised wage setting and decreasing returns to scale technology, the present paper shows that the owners' choice of...

Motivated by the fact that some regulations involve extra costs for those firms at a size beyond a critical threshold, this paper contributes to the analysis of the welfare distortions due to these regulations. In the context of a duopoly, our results show that social welfare is not monotonic...

This study constructs a successive Cournot model to investigate the possibility that a separated upstream input supplier can solely sell the intermediate good to a separated downstream manufacturer through an exclusive contract in the presence of a vertically integrated rival. We find that the...
