Monetary Policy And The Management Of The Public Debt

This paper proposes a sovereign asset and liability management framework for analyzing the inter-relationships between debt management, fiscal and monetary policies. It illustrates the consequences of uncoordinated policy mix and extends Sargent and Wallace (1981 and 1993) by including debt management. Examples of policy games played by fiscal, monetary, and debt management authorities reinforce the importance of policy separation and coordination to prevent domination by one authority over another which could lead to inconsistent policy mix.

The initial government debt-to-GDP ratio and the government’s commitment play a pivotal role in determining the welfare-optimal speed of fiscal consolidation in the management of a debt crisis. Under commitment, for low or moderate initial government debt-to-GPD ratios, the optimal consolidation is very slow. A faster pace is optimal when the economy starts from a high level of public debt implying high sovereign risk premia, unless these are suppressed via a bailout by official creditors. Under discretion, the cost of not being able to commit is reflected into a quick consolidation of government debt. Simple monetary-fiscal rules with passive fiscal policy, designed for an environment with “normal shocks”, perform reasonably well in mimicking the Ramsey-optimal response to one-off government debt shocks. When the government can issue also long-term bonds–under commitment–the optimal debt consolidation pace is slower than in the case of short-term bonds only, and entails an increase in the ratio between long and short-term bonds.

Edited by V. Sundararajan, Peter Dattels, and Hans Blommestein, this volume outlines strategies for managing public debt, developing government securities markets, and coordinating those activities with monetary management through legal, administrative, and operational arrangements. Both transition and market economies are surveyed. The analysis draws partly on the literature on the microstructure of markets and auction systems and on selected country experiences.
