"Macroeconomics Meets Hyman P. Minsky: The Financial Theory of Investment"

Abstract

Expanding on an approach developed by financial economist Hyman Minsky, the authors of this new working paper present an alternative to the standard "efficient markets hypothesis"--the relevance of which Minsky vehemently denied. Minsky recognized that, in a modern capitalist economy with complex, expensive, and long-lived assets, the method used to finance asset positions is of critical importance, both for theory and for real-world outcomes—one reason his alternate approach has been embraced by Post Keynesian economists and Wall Street practitioners alike. Coauthors L. Randall Wray and Eric Tymoigne argue that the current financial crisis, which began with the collapse of the U.S. subprime mortgage market in 2007, provides a compelling reason to show how Minsky's approach offers us a solid grounding in the workings of financial capitalism. They examine Minsky's extension to Keynes's investment theory of the business cycle, which allowed Minsky to analyze the evolution, over time, of the modern capitalist economy toward fragility--what is well known as his financial instability hypothesis. They then update Minsky's approach to finance with a more detailed examination of asset pricing and the evolution of the banking sector, and conclude with a brief review of the insights that such an approach can provide for analysis of the current global financial crisis.
