This paper investigates economic, political, and institutional constraints to fiscal policy implementation in sub-saharan Africa. We find that planned fiscal adjustments or expansions are less likely to be implemented the larger they are, the more inaccurate the growth forecasts they are based...

We use the IMF's Global Fiscal Model to evaluate recent proposals to reform social security and the tax system in the United States. Introducing personal retirement accounts is unlikely to yield significant macroeconomic benefits unless it spurs additional fiscal consolidation to prevent a large...

Researchers in policymaking institutions have expended significant effort to develop a new generation of macro models with more rigorous microfoundations. This paper provides a summary of the applications of two of these models. The Global Economy Model is a quarterly model that features a large...

In 2005, the German government announced a far-reaching fiscal adjustment program. This paper uses the IMF’s Global Fiscal Model to study its impact and explores options for addressing long-term pressures from population aging. The growth effects of the planned VAT increase are likely modest,...

This paper examines the macroeconomic effects of different timing and composition of fiscal adjustment in the United Kingdom using the IMF’s Global Fiscal Model. Early consolidation dampens aggregate demand in the short term, but increases output in the long term as smaller primary...

We explore the underlying determinants of the macroeconomic effects of fiscal policy and tax and social security reform using the Global Fiscal Model (GFM). We show that the planning horizon of consumers, access to financial markets, and the elasticity of labor supply, as well as the...

Demographic pressures will materialize in many economies over the next few decades. We examine the macroeconomic impact of alternative fiscal adjustment and structural reform strategies to address these global aging pressures using the IMF's Global Fiscal Model (GFM). The results suggest...

This paper documents cyclical patterns of government expenditures in sub-Saharan Africa since 1970 and explains variation between countries and over time. Controlling for endogeneity, it finds government expenditures to be slightly more procyclical in sub-Saharan Africa than in other developing...

This paper presents, for the first time, multi-dimensional indices of the quality of budget institutions in low-income countries. The indices allow for benchmarking against the performance of middle-income countries, across regions, and according to different institutional arrangements that...

Japan's key fiscal challenge is to put public finances on a more sustainable footing. This paper investigates the macroeconomic implications of alternative fiscal strategies for Japan using the IMF's Global Fiscal Model. The results suggest that: (i) an adjustment package that achieves primary...
