We present a model of vertical product differentiation and exit where a domestic and a foreign firm face fixed setup costs and quality-dependent costs of production and compete in quality and price in the domestic market. Quality-dependent costs are quadratic in qualities, but independent of the...

In a model of vertical product differentiation, duopolistic firms face quality-dependent costs and compete in quality and price in two segmented markets. Minimum quality standards, set according to the principle of Mutual Recognition, can be used to increase welfare. The results of the one-shot...

In a model of vertical product differentiation, duopolistic firms face quality-dependent costs and compete in quality and price in two segmented markets. Minimum quality standards, set uniformly or according to the principle of Mutual Recognition, can be used to increase welfare. The analysis...

We analyse how strategic competition between a green firm and a brown competitor develops when their products are differentiated along two dimensions: hedonic quality and environmental quality. The former dimension refers to the pure (intrinsic) performance of the good, whereas the latter...

We prove that a sufficient condition for the core existence in a n-firm vertically differentiated market is that the qualities of firms' products are equally-spaced along the quality spectrum. This result contributes to see that a fully collusive agreement among firms in such markets is more...

We analyse how strategic competition between a green firm and a brown competitor develops when their products are differentiated along two dimensions: hedonic quality and environmental quality. The former dimension refers to the pure (intrinsic) performance of the good, whereas the latter...

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...
