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...

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...

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...

The paper explores the case for monetary and fiscal unification. Monetary policy suffers from an inflation bias because the monetary authorities are not able to commit. With international risk-sharing in a fiscal union, fiscal discipline suffers from moral hazard. An inflation target alleviates...

We analyse the proposed ‘stability pact’ for countries joining a European Monetary Union (EMU). Within EMU shortsighted governments fail to fully internalize the inflationary consequences of their debt policies, which results in excessive debt accumulation. Hence, although in the absence of...

If discretionary monetary policy implies an inflation bias, monetary unification boosts the accumulation of public debt. The additional debt accumulation is welfare reducing only if governments are sufficiently myopic. In the presence of myopic governments, debt ceilings play a useful role in...

The combination of discretionary monetary policy, labour-market distortions and nominal wage rigidity yields an inflation bias as monetary policy tries to exploit nominal wage contracts to address labour-market distortions. Although an inflation target eliminates this inflation bias, it creates...
