The interdependence of national economies implies externalities in policy making, and these externalities lead to inefficient outcomes when policy-making is decentralised and independent. These externalities have been well documented from a theoretical point of view. This paper reports our...

Following Kydland and Prescott's (1977) seminal paper on time-inconsistency, a large literature has explored possible frameworks within which monetary policy could overcome this problem -- neatly illustrated in Barro and Gordon's (1983) model. In a stochastic world there appears to be a...

Using the recent EC Commission report `One Market, One Money' as a point of reference, we consider the merits of a single currency in Europe. The main benefit is the reduction in transaction costs, which the report estimates at 0.4% of European Community (EC) GDP (but much less in countries with...

Previous empirical studies have found the gains from international policy coordination to be small relative to the imprecision with which policy can be framed. This paper investigates whether there are larger gains to strategic behavior (interpreted as Nash noncooperative equilibria), as...

Nominal price and wage rigidity renders monetary policy effective over output. However, this effectiveness extends, under widely used overlapping-wage and Calvo-contract Phillips Curves, to planned monetary policy (‘exploitability’) and not merely to policy surprises. We argue that within...

The EMS's robustness in the face of stochastic shocks is studied, using the Liverpool World Model and the optimal strategy algorithm of Brandsma and Hughes Hallett. The EMS began life in 1979 with a system design permitting regular parity changes; we find this design to be relatively unstable,...

This survey essay considers how rational expectations have changed our evaluation of monetary policy. In the first section, various underpinnings of the "Phillips curve" relation between inflation and output are reviewed. All are concluded to be products of particular institutional set-ups whose...

This new model of international trade patterns is based on differing relative labor costs derived from differing endowments of skilled and unskilled labor, when labor is in elastic supply because of social support systems. All factors other than labor are assumed to be mobile across frontiers;...

We develop a simple overlapping generations model in which the young have a choice in investing in equities and index-linked bonds. Projections of share price uncertainty over a 30-year period show that the risk associated with such a long-term investment predicts an equity premium that matches...
