We develop a stylized EU-type model of a union consisting of rich, capital-abundant and high productivity countries, and poor, capital-scarce and low productivity countries. We address two main issues: the efficiency of tax competition and the effect of factor mobility on the size of the welfare...

We study optimal transport networks in spatial equilibrium. We develop a framework consisting of a neoclassical trade model with labor mobility in which locations are arranged on a graph. Goods must be shipped through linked locations, and transport costs depend on congestion and on the...

In 2004, the European Union admitted 10 new countries, and wages in these countries were generally well below the levels in the existing member countries. Citizens of these newly-admitted countries were subsequently free to take jobs anywhere in the EU, and many did so. In 2015, a large number...

While economic theory highlights the usefulness of flexible exchange rates in promoting adjustment in international relative prices, flexible exchange rates also can be a source of destabilizing shocks. We find that when countries joining the euro currency union abandoned their national exchange...

This paper brings out the special mechanism through which taxes influence bilateral FDI, when investment decisions are two-fold in the presence of fixed setup flows costs. For each pair of source-host countries, there is a set of factors determining whether aggregate FDI flows will occur at all,...

Three large current account imbalances -- one deficit (the United States) and two surpluses (Japan and the Euro area) -- are subjected to a minimalist structural interpretation. Though simple, this interpretation enables us to assess how much of each of the imbalances require a real exchange...

The accession countries to the euro area are increasingly binding their economic activity, external and internal, to the euro area countries. One aspect of this phenomenon concerns the currency invoicing of international trade transactions, where accession countries have reduced their use of the...

The economic effects from labor market integration are crucially affected by the extent to which countries are open to trade. In this paper we build a multi-country dynamic general equilibrium model with trade in goods and labor mobility across countries to study and quantify the economic...

This paper analyzes the effectiveness of the tax and transfer systems in the European Union and the US to act as an automatic stabilizer in the current economic crisis. We find that automatic stabilizers absorb 38 per cent of a proportional income shock in the EU, compared to 32 per cent in the...

It is often argued that tax competition may lead to a "race to the bottom". Such a race may hold indeed in the case of the pure case of factor mobility (such as capital mobility). However, in this paper we emphasize the unique feature of labor migration, that may nullify the "race to the bottom"...
