This paper develops a full-fledged cost-benefit analysis of monetary integration, and applies it to the currency unions actively pursued in Africa. The benefits of monetary union come from a more credible monetary policy, while the costs derive from real shock asymmetries and fiscal disparities....

The paper revisits the link between fiscal policy and macroeconomic stability. Two salient features of our analysis are (1) a systematic test for the government’s ambivalent role as a shock absorber and a shock inducer—removing a downward bias present in existing estimates of the impact of...

This paper discusses the role of fiscal institutions, including budget rules and non-partisan agencies, in enhancing fiscal discipline. A dynamic model of fiscal policy shows that optimal institutions lack credibility unless the costs to bypass them are sufficiently high. In our model, a...

Debt relief and the scaling up of aid to low-income countries should allow for greater fiscal space for expenditure programs to create long-term growth and lower poverty rates.

The paper explores the extent to which the pressure of debt service on other spending items may push governments to embark on fiscal consolidation beyond what is strictly necessary to secure solvency. The empirical analysis identifies thresholds of interest bill indicators beyond which...
