The Balassa-Samuelson model, which explains real exchange rate movements in terms of sectoral productivities, rests on two components. First, the model implies that the relative price of non-traded goods in each country should reflect the relative productivity of labour in the traded and...

A new theory of price determination suggests that if primary surpluses are independent of the level of debt, the price level has to ‘jump’ to assure fiscal solvency. In this regime (which we call fiscal dominant), monetary policy has to work through seignorage to control the price level. If,...

It is commonly asserted that monetary and fiscal policy may have to be coordinated if they are to provide a nominal anchor and avoid the pathological outcomes of sunspots or explosive price paths. In this paper, we study a model in which government bonds are an imperfect substitute for money in...

Woodford (2003) describes a popular class of neo-Wicksellian models in which monetary policy is characterized by an interest-rate rule, and the money market and financial institutions are typically not even modelled. Critics contend that these models are incomplete and unsuitable for...

The Great Recession, and the fiscal response to it, has revived interest in the size of fiscal multipliers. Standard business cycle models have difficulties generating multipliers greater than one. And they also cannot produce any significant state-dependence in the size of the multipliers over...

We use a new theory of price determination – developed by Woodford, Simms and others – to characterize central bank independence and price stability. If fiscal policy guarantees that the price level is determined independently of government’s present value budget constraint, we can say...

While overall inflation has fallen dramatically in countries like Italy and Spain, inflation in the home good sector remains stubbornly higher than inflation in the traded good sector. If nominal exchange rates are fixed, these real appreciations imply an inflation differential with countries...

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...

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...

Monetary arrangements in Europe vacillated wildly over the last decade, and they may be expected to continue to do so over the next. The literature on this chaotic process has focused on issues of credibility. Here, we focus instead on the longer-run implications of Europe's choice of monetary...
