We analyse how market competition in a vertically differentiated polluting industry is affected by product variants that comply at different levels with "green" social norms. A green consumption behavior is considered as a byword of good citizenship. Consumer preferences depend on a combination...

In this paper, two pairs of complementors have to decide whether to merge and eventually bundle their products. Depending on the degree of competitive pressure in the market, either both pairs decide to merge (with or without bundling), or only one pair merges and bundles, while rivals remain...

The fight against cartels is a priority for antitrust authorities on both sides of the Atlantic. What differs between the EU and the US is not the basic toolkit for achieving deterrence, but to whom it is targeted. In the EU, pecuniary sanctions against the firm are the only instruments...

We investigate a dynamic Cournot duopoly with intraindustry trade, where firms invest in R&D to reduce the level of iceberg transportation costs. We adopt both open-loop and closed-loop equilibrium concepts, showing that a unique (saddle point) steady state exists in both cases. In the open-loop...

We adopt a dynamic approach to model the behaviour of a multiproduct monopolist investing in process innovation, and either product differentiation, or product proliferation, or both. Irrespective of the number of activities appearing in the R&D portfolio, we prove that, depending on initial...

We revisit a recent literature on productive asset exploitation describing a differential oligopoly game of resource extraction under static, linear feedback and nonlinear feedback strategies, where we explicitly allow for the possibility of resource exhaustion. We show that (i) feedback rules...

We revisit Maxwell's (1998) analysis to show that his results are incompatible with the assumption of full market coverage. As a consequence, the effects of MQS regulation on the high-quality firm's incentive to adopt a more efficient technology cannot be assessed in this model.
