The theory of optimal currency areas states that a single currency zone should have symmetry of shocks and structures across regions. Research on monetary union in Europe has either assumed these conditions to hold close enough not to cause problems, or has focussed on asymmetries in shocks. But...

Official calculations of automatic stabilizers are seriously flawed since they rest on the assumption that the only element of social spending that reacts automatically to the cycle is unemployment compensation. This puts into question many estimates of discretionary fiscal policy. In response,...

We examine a trade model where three countries compete for an exogenous number of firms. In our hub-and-spoke framework, one country is the hub through which all trade with and between spokes takes place. We establish the distribution of industrial activity in the absence of taxes and compare it...

The macroeconomic literature on automatic stabilization tends to focus on taxes and dismiss the relevance of government expenditure, aside from unemployment compensation. Our results go sharply contrary to this view. We engage in an empirical analysis of 20 OECD countries from 1980-2001 and find...

This paper investigates whether the higher prevalence of South multinational enterprises (MNEs) in risky developing countries may be explained by the experience that they have acquired of poor institutional quality at home. We confirm the intuitions provided by our analytical model by...

If private sector agents hold rational expectations, they will predict any future policy switches. Discounting the announced optimal policies, if they are not credible, will lead to a response which deprives the government of any incentive to renege on previous announcements and of the benefits...

We study the effects of Central Bank transparency on inflation and the output gap. We thus first identify a small analytical model, which concludes that transparency affects the variability of inflation and output and not their average levels. Then we examine whether this conjecture holds...

The early 1990s marked a distinction between the EMS as a vehicle for creating monetary stability and the EMS as a vehicle for moving towards monetary union. We model that distinction by contrasting policies generated by preference transfers from the lead country (to create the EMS discipline of...

This paper examines and compares the effectiveness of hedging and buffer-stock strategies for stabilizing the revenues of individual producers who face different supply conditions in a market with uncertainty about prices and output. The results are obtained in a model-free framework, with...

In this paper we evaluate the deterioration in the European sacrifice ratio implied (both in terms of inflation and unemployment) by the fact that labour markets are structurally different and there is very little labour mobility between the European Union countries. We also consider a wage...
