This paper fills a gap in the macroeconomic literature on renewable sources of energy. It offers a definition of green investment and analyzes the trends and determinants of this investment over the last decade for 35 advanced and emerging countries. We use a new multi-country historical dataset...

Fiscal multipliers are important tools for macroeconomic projections and policy design. In many countries, little is known about the size of multipliers, as data availability limits the scope for empirical research. For these countries, we propose a simple method—dubbed the “bucket...

The paper contributes to the discussions on fiscal governance in Europe. It takes stock of recent reforms, identifies areas for further progress, and discusses a menu of policy options for the medium-term. The issues covered include: (i) the growing complexity of the European framework and ways...

The purpose of this paper is to examine factors that have constrained South Africa's growth since the end of apartheid by comparing its GDP components and its saving and investment performance with those of 10 faster-growing countries. The study finds that sluggish investment has undermined...

This paper revisits the debate on the design of fiscal rules in resource-rich countries. Its main objective is to assess alternative systems of rules against their policy objectives, while taking into account country characteristics. One of the contributions of the paper is to propose fiscal...

This note provides guidance on how to calibrate fiscal rules, that is, how to determine the thresholds (ceiling, floor, or target) for specific fiscal aggregates constrained by rules. The note focuses, more specifically, on the calibration of the debt, balance, and expenditure rules. The note is...

Fiscal multipliers are important tools for macroeconomic projections and policy design. In many countries, little is known about the size of multipliers, as data availability limits the scope for empirical research. This note provides general guidance on the definition, measurement, and use of...

Sub-Saharan African countries have been hit, in recent years, by a cascading series of shocks that have exacerbated fiscal vulnerabilities. Significant reforms are needed to rebuild buffers and preserve the sustainability of public finances. The paper argues that a strategic approach to fiscal...

Successive reforms have brought many positive elements to the European Union's fiscal framework. But they have also increased its complexity. The current system involves an intricate set of fiscal constraints, which hampers effective monitoring and public communication. Compliance has also been...
