We analyze the effects of labor migration flows on income taxation between two countries (regions) differing by the size of their population and the level of productive efficiencies. Residents, otherwise identical, are heterogeneous because they incur different migration costs. Each resident...

In this paper we generalize the approach developed in the context of banking competition by Gabszewicz et al. (2011). In an entry/acquisition game, we allow the potential entrant in a vertically differentiated market to offer a variant lying at any level of the quality ladder and playing a...

We analyze the effects, on nonredistributive taxation and on migrations, of wage differentials existing between two countries (regions) differing by the size of their population. Residents, otherwise identical, are heterogeneous because they incur different migration costs. Each resident...

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...

In this paper we adopt a vertical differentiation model to study the effect of deregulation in the airline industry. In particular, we focus on the entry of low cost companies, which succeed in providing essential flight services at relatively cheap prices. We argue that the entry of very...

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...
