Debt, Inequality and Crisis Steve Keen Kingston University London IDEAeconomics Minsky Open Source System Dynamics www.debtdeflation.com/blogs When the economic history of our epoch is written… • There will be at least 3 themes: – Period of apparently increasing tranquillity (“Great Moderation”) – Sudden transition crisis (“Great Recession”) – Rising inequality • There should be (at least) a 4th: – Rising private debt • Because all three go together and explain each other • Mainstream (Neoclassical) macro omits both inequality & debt • According to its indicators – Period of stable growth a permanent improvement in economy – Private debt macroeconomically irrelevant – Inequality simply a product of relative productivity • No longer maintained post-Piketty – But explanation limited to “r>g” • Statistical rather than causal explanation – “Great Moderation” a sign of policy success… Mystery confluence: Great Moderation & Recession • “the past two decades has seen not only significant improvements in economic growth and productivity but also a marked reduction in economic volatility… dubbed ‘the Great Moderation’.” (Bernanke 2004) The "Great Moderation" 16 Crisis 15 14 13 12 Percent; Percent per year 11 10 9 8 7 6 5 4 3 2 1 0 0 1 2 3 4 1980 Unemployment Inflation 1984 1988 1992 1996 2000 2004 www.debtdeflation.com/blogs 2008 2012 2016 Mystery confluence: Great Moderation & Recession • Post-crisis, see Moderation & Recession as 2 separate phenomena – 1st due to good economic policy, 2nd to exogenous shock… • “Standard macroeconomic models, such as the workhorse newKeynesian model, did not predict the crisis, nor did they incorporate very easily the effects of financial instability. • Do these failures of standard macroeconomic models mean that they are irrelevant or at least significantly flawed? • I think the answer is a qualified no. Economic models are useful only in the context for which they are designed. Most of the time, including during recessions, serious financial instability is not an issue. • The standard models were designed for these non-crisis periods, and they have proven quite useful in that context. • Notably, they were part of the intellectual framework that helped deliver low inflation and macroeconomic stability in most industrial countries during the two decades that began in the mid-1980s.” – Bernanke 2010 “Implications of the Financial Crisis for Economics” • What utter, self-serving, bollocks! Behaviorism vs Structuralism • Neoclassical DSGE models failed to anticipate crisis • Models use “behavior of rational agents” as basis of modeling – Since “Lucas Critique”, have asserted must capture “deep parameters” of individual behaviour for model to be valid • Post Keynesians have used “structure of economy” as basis – “Behaviour under fundamental uncertainty” considered – But behavioural concepts secondary to economic structure • My work combines this tradition with complex systems approach – Essence of complex systems: “simple system, complex behavior” – Sophisticated agent behaviour unnecessary to capture essential features of last 30 years of macroeconomics that Neoclassical models completely missed • Period of apparent diminishing cycles in employment & inflation • Rising private debt • Rising inequality as wages share falls, bankers’ share rises • Eventual crisis Simple rules, complex behaviour • My 1995 Minsky model can be stated as strict identities: • The employment rate will rise if economic growth exceeds the sum of growth in labor productivity and population growth;

Modern Debt Jubilee • Stop falsely thinking of banks as warehouses (“Loanable Fund” view) • Start thinking of them as “money factories” – Can over-produce money and debt – Write-off of excess production should be routine – Especially since recent production socially counterproductive • Asset bubbles caused by leverage – Mortgage acceleration drives house price change – Margin acceleration drives share price change • Effectively funding Ponzi Schemes… Conclusion • Theoretical: getting structure of economy (including finance) right more important than accurately modelling agent behaviour • Revised realistic view of banking essential to understand where the crisis came from & work out how to escape it • Monetary complex systems macro needed in theory and policy • Practical: current situation inevitably will give rise to political conflict – Modern politics dominated not by Eisenhower’s “military-industrial complex” but Minsky’s “politico-financial complex” – Conventional “Ordo-Liberal” response to crisis (as in Greece) compounds basic weaknesses of capitalism • Modern Debt Jubilee needed to save capitalism from its own dynamics
