An investigation of the problems of policy formation has to take account of the way in which expectations may be formed. The assumption of rationality is often made on the grounds that there is no reason to assume that views of the future display any particular bias. Some authors take this...

This paper analyses four costs which may be associated with monetary union. First it (obviously) allows no `relative' monetary accommodation of the kind which may assist when dealing with asymmetric shocks. This can impose significant adjustment costs. Second it does not of itself prevent...

A North-South growth model is presented which focuses on i) the complementarity of Southern output (consumption goods) and Northern output (capital goods) and ii) the terms of trade as a mechanism linking the growth rates of the two regions. This Kaldorian model is different from recent...

We analyse the stability of countries within a monetary union in the face of asymmetric shocks, using a simple but widely applicable model. We show that members of the union may be subject to severe, and possibly unstable, cycles following asymmetric shocks if there is a significant backward...

This paper investigates the importance of fiscal policy in providing macroeconomic stabilisation in a monetary union. We use a microfounded New Keynesian model of a monetary union which incorporates persistence in inflation and non-Ricardian consumers, and derive optimal simple rules for fiscal...

We analyse the events leading to the devaluation of the Mexican peso last year, using a simple two-period model. We view the problem as a race between a foreign investment led demand boom and the potential expansion in supply which might follow; the outcome of such a race is inherently...

We analyse optimal discretionary games between a benevolent central bank and a myopic government in a New Keynesian model. First, when lump-sum taxes are available and public debt is absent, we show that a Nash game results in too much government spending and excessively high interest rates,...

The paper evaluates some proposals for macroeconomic stabilization in an open economy, which take the form of simple rules. The first rule assigns monetary policy to inflation control and does not require fiscal intervention. The second rule adds fiscal control of a foreign wealth target to the...

This paper first briefly describes the role of the WTO and its history. It then lays out a simple bargaining model of international negotiations, which can be used for understanding the Doha round of talks. This simple framework is used to distil and discuss a number of potential explanations...

This paper considers fiscal and monetary policy in a short-run static macroeconomic model. There are two objectives, control of inflation and control over the growth of national wealth, and a third outcome of importance, a high level of employment. There are two instruments, monetary policy (the...
