Evidence from a large panel of low-income and lower middle-income countries over the period 1995-2012 suggests that, contrary to other countries, public investment in the West African Economic and Monetary Union (WAEMU) has been pro-cyclical. Public investment contracts more in "bad times" than...

Promoting sustainable development calls for investing rents from exhaustible mineral resources into human, physical and social capital, so as to protect the wealth of countries and the economic opportunities of their citizens. This has been difficult in well-governed Ghana in the last decade; and...

The objective of this paper is to inform Liberia's medium-term growth and development strategy for 2012-17 and its National Vision: Liberia Rising 2030, both of which are under preparation. The analysis is based on MAMS (Maquette for MDG [Millennium Development Goal]) Simulations, a computable...

This paper uses a computable general equilibrium model to assess the welfare impact of commodity price inflation in Tanzania and possible tax policy responses in the short, medium, and long term. The results suggest that global commodity inflation since 2006 may have had a significantly negative...

This paper attempts to identify Lebanon's greatest constraints to economic growth, following a growth diagnosis approach. It concludes that fiscal imbalances and barriers to entry are most binding on long-term growth. Macroeconomic imbalances and related perceived risks affect the nature of...

The virus that triggered a localized shock in China is now delivering a significant global shock. This study simulates the potential impact of COVID-19 on gross domestic product and trade, using a standard global computable general equilibrium model. It models the shock as underutilization of...

China's Belt and Road Initiative aims to improve connectivity between China and more than 70 countries through infrastructure investment and regional cooperation.
