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...

There is substantial consensus in the literature that positive uncertainty shocks predict a slowdown of economic activity. However, using US data since 1950 we show that the macroeconomic response pattern to stock market volatility shocks has changed substantially over time. The negative...

We explore the implications of monetary unification for real interest rates and (relative) public debt levels. The adoption of a common monetary policy renders the risk-return characteristics of the participating countries more similar, so that the substitutability of their public debt increases...

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...

This Paper analyses the decision of a government facing electoral uncertainty to implement structural reforms in the presence of fiscal restraints similar to the Stability and Growth Pact. We provide suggestive evidence that structural reforms - in particular labour market reforms - may lead to...

This article provides an overview of recent research into the macroeconomic costs and benefits of monetary unification. We are primarily interested in Europe's monetary union. Given that unification entails the loss of a policy instrument, its potential benefits have to be found elsewhere....

We explore the dynamics of public debt in the presence of political shocks, in the form of shocks to preferences for public spending. Under commitment, optimal stabilization is obtained by combining an inflation target that is contingent on the political shock with a debt target that forces the...

This paper explores the interaction between centralized monetary policy and decentralized fiscal policy in a monetary union. Discretionary monetary policy suffers from a failure to commit. Moreover, decentralized fiscal policymakers impose externalities on each other through the influence of...

This paper explores under what conditions a European Monetary Union (EMU) is an optimum currency area. The scope for an EMU increases with convergence of structural and fiscal policies, small money holdings, a conservative European Central Bank, and dependent national central banks. How national...

It is widely argued that Europe's unified monetary policy calls for international coordination at the fiscal level. We survey the issues involved with such coordination of fiscal policy as a demand management tool and we use a simple model to investigate the circumstances under which...
