Firms in developing countries that seek outside financing for investment must often choose their debt-equity combinations in the face of financial market constraints on debt service, on outside equity financing, and on internal finance (endowments). Inefficiencies in the allocation of available finance and in the equity-debt choices that can ensue can be prevented by appropriate policy measures to improve information on profitable investment opportunities and about firms; to directly strengthen financial intermediation; and to support appropriate credit guarantee schemes.

A payment system encompasses a set of instruments and means generally acceptable in making payments; the institutional and organizational framework governing such payments, including prudential regulation; and the operating procedures and communications network used to initiate and transmit payment information from payer to payee and to settle payments. This book, by Omotunde E.G. Johnson, with Richard K. Abrams, Jean-Marc Destresse, Tony Lybek, Nicholas Roberts, and Mark Swinburne, identifies main policy and strategic issues in payment system reform, describes the structure of payment systems in selected countries, highlights areas of consensus, and suggests the direction for future policy analysis.
