Within a standard model of monetary delegation we show that the optimal linear inflation contract performs strictly better than the optimal inflation target when there is uncertainty about the central banker’s preferences. The optimal combination of a contract and a target performs best, and...

No. I demonstrate that econometric estimations of nominal interest rate rules may tell little, if anything, about an economy's determinacy properties. In particular, correct inference about the interest-rate response to inflation provides no information about determinacy. Instead, it could...

So far, the 'New Open Economy Macroeconomics' literature has primarily focused on monetary policy and monetary policy rules, rather than paying attention also to fiscal policy. This is an omission because, especially with the advent of EMU, the burden on fiscal policy as an instrument for...

According to most academics and policymakers, transparency in monetary policymaking is desirable. I examine this proposition in a small theoretical model emphasizing forward-looking private sector behaviour. Transparency makes it easier for price setters to infer the central bank's future policy...

We show how a stability pact based on deficit sanctions eliminates the exacerbation of debt accumulation that may arise from monetary unification. Moreover, by making sanctions contingent upon the economic situation of countries, the stability pact provides for risk sharing. Differences in...

We study optimal monetary and fiscal stabilization policy in a two-country monetary union in the presence of (inefficient) mark-up shocks, price rigidities and monopolistic competition. The underlying dynamic system contains two Phillips curves featuring public spending and mark-up shocks. We...

We show that the ECB's interest rate changes during 1999-2010 have been mainly driven by changes in economic activity in the Euro area. Changes in actual or expected future HICP inflation play a minor, if any, role.

In the last decades, capital markets across the industrialized world have undergone massive deregulation, involving increases in the loan-to-value (LTV) ratios of households and firms. We study the business-cycle implications of this phenomenon in a dynamic general equilibrium model with...

Within a simple New Keynesian model emphasizing forward-looking behaviour of private agents, I evaluate optimal nominal income growth targeting versus optimal inflation targeting. When the economy under consideration is mainly subject to shocks that do not involve monetary policy trade-offs for...

We explore endogenous monetary unification in the context of a model in which a country with serious structural distortions (and, hence, high inflation) is admitted into a monetary union once its economic structure has converged sufficiently towards that of the existing participants. If...
