Leith and Wren-Lewis (2007) have shown that government debt is returned to its pre-shock level in a New Keynesian model under optimal discretionary policy. This has two important implications for monetary and fiscal policy. First, in a high-debt economy, it may be optimal for discretionary...

This paper uses a New Keynesian framework to study the coordination of fiscal and monetary policies, in response to an inflation shock when the policymaker acts with commitment. We first show that, in the simplest New Keynesian model, fiscal policy plays no part in the optimal policy response,...

In earlier work we documented two episodes in which a sharp fiscal consolidation was associated with a surprisingly large expansion in private domestic demand. In this paper we draw on further evidence to investigate if and when fiscal policy changes can have such non-Keynesian effects. In the...

This paper develops a real model of financial crisis, and uses it to elucidate the controversy between Joe Stiglitz and the IMF concerning the Asian financial crisis. Borrowers of foreign capital are bound by lending contracts to pay the world rate of return on their borrowing, following an...

This paper analyzes the impact of terms of trade and risk-premium shocks on a small open economy in an intertemporal, Dutch disease model, with international capital mobility. It is shown that when the economy experiences a permanent improvement in the terms of trade, the Dutch disease effect...

In an economy with financial imperfections, Ricardian equivalence holds when prices are flexible and the steady-state distribution of consumption is uniform, or labor is inelastic. With different steady-state consumption levels, Ricardian equivalence fails, but tax cuts, somewhat paradoxically,...

A central tenet of the Maastricht Treaty is that a successful European Monetary Union requires sustainable public finances of its member states. Yet there is no clear definition of sustainability. The economist’s common use of the term builds on the concept of an intertemporal budget...

Under free capital mobility, confidence crises can lead to devaluations even when fixed exchange rates are viable, if fiscal authorities can obtain temporary money financing of deficits. During a crisis domestic interest rates increase, reflecting the expected devaluation. Rather than selling...

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...

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...
