Houses and apartments sold in New York and New Jersey at prices above $1 million are subject to the so-called 1% “mansion tax" imposed on the full value of the transaction. This policy generates a discontinuity (a “notch") in the overall tax liability. We rely on this and other...

This paper argues that increased factor mobility incurs the risk of dismantling the welfare state, even though this state may have useful allocative functions. It will be difficult to finance the welfare state with taxes on capital and it may be necessary to subsidize this factor in the sense...

We study the impact of tax competition on equilibrium taxes and welfare, focusing on the jurisdictional fragmentation of federations. In a representative-agent model of fiscal federalism, fragmentation among jurisdictions with benevolent tax-setting authorities unambiguously reduces welfare. If,...

This paper examines a model of jurisdiction formation where individuals differ in both income and preferences, and where public provision choices within jurisdictions are the outcome of a political process, but can be supplemented by private contributions. Locational equilibria in this model can...

This paper analyses the effect of different types of regional subsidies to poor regions on industrial location, employment, income inequality - between and inside regions - and welfare. We show that the impact on location of such subsidies is stronger when trade costs are low. When firms are...

In 1500, Europe was composed of hundreds of statelets and principalities, with weak central authority, no monopoly over the legitimate use of violence, and multiple, overlapping levels of jurisdiction. By 1800, Europe had consolidated into a handful of powerful, centralized nation states. We...

This paper addresses two basic issues related to technological innovation and climate stabilisation objectives: i) Can innovation policies be effective in stabilising greenhouse gas concentrations? ii) To what extent can innovation policies complement carbon pricing (taxes or permit trading) and...

Although there are exceptions, most European universities and institutions of higher education find it difficult to compete with the best universities in the Anglo-Saxon world. Despite the Bologna agreement and the ambitions of the Lisbon agenda, European universities are in need of fundamental...

This paper provides factual evidence on the extent of public intervention in the Italian economy. It further illustrates the internal contradictions and weaknesses of public action in Italy. New policy proposals to solve old structural problems of the Bel Paese are then discussed. Among them, a...

The role of social background for educational choices and outcomes is considered in an overlapping generations setting. It is shown that the impediments for education created by social factors are similar to a market imperfection, and publicly provided education may lead to a Pareto improvement....
