Minsky’s financial instability hypothesis and the role of equity: The accounting behind hedge, speculative, and Ponzi finance

Hyman Minsky’s primary legacy to Keynesian macroeconomics involves two related features. He emphasized that real (market) analysis and financial (market) analysis should be analyzed together, not separately; and that the macro economy is inherently unstable (his “financial instability hypothesis”). He melded financial analysis and the “real” market economy to interpret cycles in economic activity. An economy in boom (euphoria, animal spirits) eventually runs out of steam, reaches a peak, and descends into recession. The recession after the Minsky-moment peak segues through several financial stages based on the financial conditions of individual firms; he termed these stages as hedge, speculative, and Ponzi finance. The fragility of the economy depends on the relative weights or importance of the economy’s firms in each of the three stages.
