Financing the Future explains how the unique governance arrangements and financial model of Multilateral Development Banks (MDB) shape their behavior. Outlining a theoretical framework suitable to the 30-odd MDBs around the world, the book uses this to show how different sets of MDBs are grappling with the challenges of the 21st century. This is the first book to explain the core of the MDB model as a unique class of international institution and shows how that model is playing out the traditional large MDBs, smaller borrower-led banks, and the two new MDBs recently created with the support of China. The combination of an original theoretical approach, rich quantitative and qualitative empirics, and clear writing means this book will appeal to both academic and practitioner audiences.
