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...

This paper investigates the strategic effect of bundling when a multi-product firm producing two complements faces competition in both markets. I consider a demand structure where both Cournot and Bertrand competition can be evaluated. Bundling is completely ineffective when firms compete in...

We study the effects of integration of asymmetric complements when they are vertically differentiated. While confirming the standard effects of integration, namely the internalization of the double marginalization externality and the reduction of competition, we point out a new positive quality...

This note is concerned with the effects of joint ownership of complements when they are vertically differentiated. We provide strong arguments for the positive nature of network integration among firms, while showing at the same time that, in some circumstances, anti-competitive consequences can...

In this paper, under the assumption that green consumption has (at least partially) a social/psychological dimension, we analyse the effect of a carbon tax when it is imposed on consumers buying dirty products rather than on polluting firms. The amount of the tax paid is determined by the share...
