We set up a model of generalised oligopoly where two countries of different size compete for an exogenous, but variable, number of identical firms. The model combines a desire by national governments to attract internationally mobile firms with the existence of location rents that arise even in...

Should the European Union grant state aid through an institution like the European Investment bank? This paper evaluates the efficiency of different measures for granting state aid. We use a theoretical model with firms that differ in their creditworthiness and compare different types of...

This paper examines the efficient provision of goods in two-sided markets and characterizes optimal specific and ad-valorem taxes. We show that (i) a monopoly may have too high output compared to the social optimum; (ii) output may be reduced by imposing negative value-added taxes (subsidy) or...

Altruistic parents, who differ in income, make financial transfers to their children, who differ in ability. The children invest in post-compulsory education, subject to an endogenous credit constraint, and taking policy as given. There are two policy tools: a subsidy to those who participate in...

This paper analyzes subsidies for intracity and intercity commuting in an urban economics framework with two cities and agglomeration externalities, where workers may commute within and between cities. First, commuting subsidies serve to internalize agglomeration externalities: Intracity...

A national-champions-related industrial policy has become (again) en vogue among European politicians. Against this background, our work orders different types of national champions along the industry lifecycle. Different types of locally bound externalities appear along the lifecycle. In a...

In a model with ex-ante homogenous households, earnings risk and a general earnings function, we derive the optimal linear labor tax rate and optimal linear education subsidies. The optimal income tax trades off social insurance against incentives to work and to invest in human capital....

In this paper, we analyse the role of mobility in tax and subsidy competition. Our primary result is that increasing relocation mobility of firms leads to increasing net tax revenues under fairly weak conditions. While enhanced relocation mobility intensifies tax competition, it weakens subsidy...

This paper shows that subsidy competition may be efficiency enhancing. We model a subsidy game among two asymmetric regions in a new trade model, where capital can freely move among regions, but capital rewards are repatriated. We study subsidy competition, starting from an equilibrium where the...

This paper develops sufficient conditions under which the Weak Green Paradox may (and may not) hold in terms of subsidies for biofuel production such that the supply-side responses by fossil fuel producers may more than offset the substitution to biofuels. Analytical results are derived and...
