Private Finance and Public Policy

Abstract

This Working Paper should not be reported as representing the views of the IMF. The views expressed in this Working Paper are those of the author(s) and do not necessarily represent those of the IMF or IMF policy. Working Papers describe research in progress by the author(s) and are published to elicit comments and to further debate. This paper articulates a logical foundation-drawn from disparate literatures-for understanding why safeguarding financial stability is an important economic policy objective. The paper also explains why private aspects of finance provide broader social economic benefits and have the characteristics of public goods. Unique aspects of finance are examined, as are the linkages between finance, money, and the real economy. Sources of market imperfections in finance are identified and their implications are analyzed. The arguments imply that reaping the full private and social economic benefits of finance requires both private-collective and public-policy involvement as well as a delicate balance between maximizing the benefits of positive externalities (and public goods) and minimizing the costs (including potential instabilities) of other sources of market imperfections in finance.
