When he began this book in early 2008, Guillermo Perry argued that developing countries remained highly vulnerable to external risks such as commodity price declines, capital flow reversals, and natural disasters. The economic crisis that has since ensued confirmed Perry's analysis. It has also made his proposal more important than ever: multilateral development banks (MDBs) should move beyond lending to provide innovative risk-management tools for developing countries to manage volatility. The risk that MDBs will fall into complacency as the short-term demand for traditional loans increases during the crisis should not deter innovations to ensure long-term stability. Contents 1.
