This paper examines how capital tax competition affects jurisdiction formation. We describe a locational model of public goods provision, where jurisdictions are represented by coalitions of consumers with similar tastes, and where the levels of taxation and local public goods provision within...

This paper introduces perfect substitutability between private and public consumption in a dynamic, open economy with imperfect competition and nominal rigidities. This implies a direct crowding-out effect that, generalizing to the two-country case some well-known properties of a closed economy,...

This article analyses cartels that act as a Stackelberg leader with respect to a competitive fringe in industries supplying differentiated products. The main objectives are to investigate how cartel stability changes with the degree of differentiation and the cartel size, to predict endogenous...

We examine the endogenous formation of trade blocs when markets are characterized by imperfect competition and governments use import tariffs and export subsidies to alter the strategic interactions between oligopolistic firms. Using a simple model of intra-industry trade between three ex-ante...

This paper considers irreversible investment in competing research projects with uncertain returns under a winner-takes-all patent system. Uncertainty takes two distinct forms: the technological success of the project is probabilistic, while the economic value of the patent to be won evolves...

We start the survey by reviewing the implications of horizontal and vertical product differentiation on market structure under the assumption of single-product firms. Then, we analyze the main results of the multi-product firm models, both when variants are assumed differentiated in vertical...

This paper investigates whether tax competition can survive under tax coordination, when information is private or nonverifiable. WE focus on a two-jurisdiction model where capital can move across borders, and where jurisdictions have different public goods requirements, but are otherwise...

This paper proposes a general framework for analyzing commodity tax competition under destination and origin principles, based on three possible tax spillovers, the consumer price spillover, the producer price/terms of trade spillover, and rent spillovers. A model is presented which can be...
