Abstract

This paper attempts to reconcile the need for flexibility in fiscal policy, with the need for credibility and consistency in monetary policies. The idea is to generate fewer conflicts between policies but greater discipline within them. We assume an independent central bank and restraints on the use of national fiscal policies. Using a theoretical model, we examine the consequences of assigning leadership to fiscal or monetary policies to exploit the implicit (rule based) coordination available under standard transmission mechanisms, but where priorities and targets differ between policy makers. This works best with fiscal leadership: we introduce a debt rule (with hard or soft targets) to precommit fiscal policies over the longer term, but use monetary independence to guarantee credibility and discipline in the short run stabilization policies. Compared to the uncoordinated solution now operating in Europe, inflation biases are lower and debt repayments higher for no loss in output volatility. That corresponds to the experience of the UK, our benchmark case, whose empirical reaction functions show fiscal leadership. Across ten OECD countries, these gains are estimated to be worth 2%-4% of GDP.
