The delegation of monetary policy to a supranational Central Bank creates a conflict of interest between residents of different countries. For example, the country in recession favours more inflation to boost output, while the country in boom prefers exactly the opposite. This conflict gives...

In this paper we analyse how the creation of a single currency regime changes the strategic relationship between policy-makers, both within and across countries. In particular we look at the role of cross-country externalities and lack of commitment. When labour taxation is excessive, due to...

This paper illustrates some of the most important insights of the literature on international fiscal and monetary policy coordination. It notes that the analysis of international policy interactions is enriched by taking the incentives in the domestic policy process into account. These...

This paper studies the interactions of fiscal and monetary policy when they stabilise a single economy against shocks in a dynamic setting. We assume that fiscal and monetary policies both stabilise the economy only by causing changes to aggregate demand. Our findings are as follows. If the both...

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...

Rational expectations are often used as a strong argument against policy activism, as they may undermine or neutralize the policymaker’s actions. Although this sometimes happens, rational expectations do not always imply policy invariance or ineffectiveness. In fact, in certain circumstances...

This Paper explores the quantitative implications of an approach to monetary policy that gained prominence in the United States during the 1990s. Proponents of this approach recommend that, when inflation is moderate but still above the long-run objective, the central bank should not move...

This paper probes the limits of transparency in monetary policymaking along two dimensions: feasibility and desirability. It argues that, due to limited knowledge about the economy, even central banks that are considered champions of openness are not very clear about their measures of the output...

Several recent studies imply that the response of national saving to fiscal policy is non-monotonic. In this paper, we use two data sets to search for the circumstances in which such non-monotonic responses arise: one refers to a sample of OECD countries, as in previous studies, and one to a...

Central banks’ economic and political importance has grown in advanced economies since the start of the Great Financial Crisis in 2007. An unwillingness or inability of governments to use countercyclical fiscal policy has made monetary policy the only stabilization tool in town. However, much...
