The crisis in economics & economic theory Steve Keen University of Western Sydney Debunking Economics www.debtdeflation.com/blogs www.debunkingeconomics.com 13 Macroeconomics Before the Crisis: Triumphalism • “Macroeconomics was born as a distinct field in the 1940's, as a part of the intellectual response to the Great Depression. • The term then referred to the body of knowledge and expertise that we hoped would prevent the recurrence of that economic disaster. • My thesis in this lecture is that macroeconomics in this original sense has succeeded: • Its central problem of depression prevention has been solved, for all practical purposes, and has in fact been solved for many decades.”(Lucas 2003) Macroeconomics Before the Crisis: Triumphalism • “As it turned out, the low-inflation era of the past two decades has seen not only significant improvements in economic growth and productivity • but also a marked reduction in economic volatility, both in the United States and abroad, a phenomenon that has been dubbed “the Great Moderation”. • Recessions have become less frequent and milder, and quarter-to-quarter volatility in output and employment has declined significantly as well. • The sources of the Great Moderation remain somewhat controversial, but as I have argued elsewhere, there is evidence for the view that improved control of inflation has contributed in important measure to this welcome change in the economy.” (Bernanke 2004) Macroeconomics Before the Crisis: Triumphalism • “there has been enormous progress and substantial convergence… • Facts have a way of eventually forcing irrelevant theory out (one wishes it happened faster), and good theory also has a way of eventually forcing bad theory out. • The new tools developed by the New-Classicals came to dominate. • The facts emphasized by the New-Keynesians forced imperfections back in the benchmark model. A largely common vision has emerged… • The state of macro is good…” (Blanchard 2008, 2009) – Published as working paper 1 year after crisis began! And then there was an exogenous shock… • From “The Great Moderation”… • To “The Great Contraction” 15 12.5 300 Unemployment Inflation Debt 10 250 Percent 7.5 5 200 2.5 0 2.5 5 1980 • & “The Jobless Recovery” 0 150 Unemployment Inflation 1985 1990 1995 2000 2005 www.debtdeflation.com/blogs 2010 100 2015 Macroeconomics After the Crisis: Evasion • “These models were designed to describe aggregate economic fluctuations during normal times when markets can bring borrowers and lenders together in orderly ways, not during financial crises and market breakdowns.” (Sargent in Rolnick 2010) • “Are … standard macroeconomic models … significantly flawed? I think the answer is a qualified no… • 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.” (Bernanke 2010) • “It is important to start by stating the obvious, namely, that the baby should not be thrown out with the bathwater.” (Blanchard, Dell'Ariccia and Mauro 2010) Macroeconomics After the Crisis: Evasion • Permanently negative random exogenous shocks?… • “the Great Recession began in late 2007 and early 2008 with a series of adverse preference and technology shocks in roughly the same mix and of roughly the same magnitude as those that hit the United States at the onset of the previous two recessions… • The string of adverse preference and technology shocks continued, however, throughout 2008 and into 2009. Moreover, these shocks grew larger in magnitude, adding substantially not just to the length but also to the severity of the great recession…” (Ireland 2011; see also McKibbin and Stoeckel 2009) Monetary Macroeconomic Realism • Non-neoclassical economic realism: – Endogenous crisis, not exogenous shock – Growth of private debt caused “Great Moderation” – Slowdown in growth of debt caused “Great Recession” – Crisis will continue until deleveraging ends • Neoclassical macro incapable of analysing these factors • Key problem: blindsided by “exogenous money” fallacy… The exogenous money fallacy • Individuals/companies have two sources of spending: – Income – Increase in debt • Neoclassical theory counts the first, ignores the second – Debt transfers money from saver to borrower – Only distribution of debt matters, not aggregate level • Fisher's “Debt Deflation” theory ignored: • “because of the counterargument that debtdeflation represented no more than a redistribution from one group (debtors) to another (creditors). • Absent implausibly large differences in marginal spending propensities among the groups … pure redistributions should have no significant macroeconomic effects…” (Bernanke 2000) The exogenous money fallacy • “Ignoring the foreign component, or looking at the world as a whole, the overall level of debt makes no difference to aggregate net worth—one person's liability is another person's asset… • In what follows, we begin by setting out a flexible-price endowment model in which “impatient” agents borrow from “patient” agents, but are subject to a debt limit.” (Krugman and Eggertsson 2010) • “the debt we create is basically money we owe to ourselves, and the burden it imposes does not involve a real transfer of resources. • That’s not to say that high debt can’t cause problems — it certainly can. But these are problems of distribution and incentives, not the burden of debt as is commonly understood.” (Krugman 2011) The exogenous money fallacy • Patient lends to Impatient • • • • Patient’s spending power goes down Impatient’s spending power goes up No change in aggregate demand Banks mere intermediaries (ignored in analysis) The endogenous money reality • Logically & Empirically false – Lending is not “transfer from saver to borrower” – But money creation “out of nothing” • “Even though the conventional answer to our question is not obviously absurd, yet there is another method of obtaining money for this purpose, which … does not presuppose the existence of accumulated results of previous development… • This method of obtaining money is the creation of purchasing power by banks… • It is always a question, not of transforming purchasing power which already exists in someone's possession, but of the creation of new purchasing power out of nothing…” (Schumpeter, 1934) • New debt net source of new investment & speculation Actual “endogenous money” process • Entrepreneur approaches bank for loan • Bank grants loan & creates deposit simultaneously • Alan Holmes, Senior V-P, New York Fed • “In the real world, banks extend credit, creating deposits in the process, and look for the reserves later.” (1969) • New loan puts additional spending power into circulation • Aggregate demand exceeds demand from income alone • Neoclassical macro wrong to ignore change in debt “Endogenous money” changes everything • Explains why dynamics of debt caused boom and bust • Aggregate demand = Income + Change in Debt – Income (mainly) finances consumption – Change in debt (mainly) finances: • Investment (new factories, innovation) • Speculation (gambling on asset prices) • Spent on – New goods and services (the real economy) – Financial claims on existing assets (the FIRE economy) • Call this Net Asset Turnover: – Price of assets (DJIA, Case-Shiller Index) – Times quantity (Number of shares, houses) – Annual turnover (% sold each year) “Endogenous money” changes everything • Aggregate accounting balance is not “Walras’ Law” – “Aggregate Demand is Aggregate Supply” • But “Walras-Schumpeter-Minsky Law” – Income + Change in Debt = GDP + NAT • Growth accounting balance is – Change in Income; – Plus Acceleration in Debt (Change in the change…) – Equals – Change in GDP plus – Change in NAT • Most of which is Change in Share & House Prices “Endogenous money” changes everything • Basic Logic: 2 d Y D GDP NAT dt NAT PA QA TA d d d d Y 2 D GDP PA QA TA dt dt dt dt “Endogenous money” changes everything • Since accelerating debt causes asset price bubbles – Bubbles must burst, because acceleration must end – Just like a car can’t accelerate forever • At maximum velocity, acceleration is zero • Applying this to: – Why the economy boomed from 1993-2007 – Why it crashed in 2007 – Why asset markets crashed as well Boom & Bust: debt-charged growth & collapse • Rising private debt boosted demand by $4 trillion at peak • Falling debt cut demand by $2.8 trillion at trough • From $18.3 to $11.5 trillion in just 2 years US $ million p.a.
