• Autocatalytic process: the outcome of the process is itself a catalyst for the process Chain Reaction!
• Viking success propelled Viking success.… but then came Collapse (Jared Diamond)
• Realized profits repay debts … propel more debt… but then comes collapse (Hyman Minsky)
Minsky’s World•Quasi – rents: cash flows available to pay debts•PI – [supply] price of investment goods
•PK – [demand] price of kapital goods•Borrower’s risk•Lenders risk•Hedge finance: E(cash flows) > Payment commitment•Speculative finance: E(cash flows)<Commitment
… but > Interest commitment Roll over debt•Ponzi finance: E(cash flows)<Interest commitment
… Expect to increase debt•Financial fragility: mix of Hedge – Spec – Ponzi
Good times Confidence Risk-taking Fragility
Minsky’s World – Keynes’ World Y = C + I
Fluctuations in I Fluctuations in Y• Expectations and degree of confidence
• Animal spirits• Subject to sudden and violent change
• Complex interactions of decisions/outcomes/liquidity/confidence
Booms and Busts
The Minsky FootprintRealized expectations Increased profits & Reduced risk BOOMDisappointed expectations Reduced profits & Confidence Bust
Rush to liquidity Debt deflation

Stabilizing an Unstable Economy
Hyman Minsky1919 - 1996
Financial Instability Hypothesis:•Hedge finance•Speculative finance•Ponzi finance
Two types of risk affect the volume of investment. …The first is the entrepreneur's or borrower's risk and arises out of doubts in his own mind as to the probability of his actually earning the prospectiveyield for which he hopes. If a man is venturing his own money, this is the only risk which is relevant.…But where a system of borrowing and lending exists, a second type of risk is relevant which we may call the lender's risk. GT, Chapter 11.

When expectations are disappointed,investment collapses … but debts remain
A Minsky Cycle•Displacement (invention, easy money)•Boom…successful speculation•Euphoria…financial innovation•Profit taking
•Panic
Student of Simons/Schumpeter
Akerlof and Shiller, Animal Spirits• Confidence – Keynes-Minsky
• Hopes, Exuberance, Fears• Waves of optimism and pessimism
• Corruption - Bad Faith Loss of Trust• S&Ls – Enron – Sub-prime crisis – Goldman Sachs
• Fairness• Punish cheaters, even at own expense• Relative position
• Money illusion• “Illusion” is real in view of nominal contracts/accounts• Money illusion Inflation – unemployment tradeoff
“So long as money retains its age-old power to deceive, inflation can be used to resolve economic conflict.” James Tobin
• Stories• New eras – Irrational exuberance
Downward wage rigidity
Akerlof and Shiller: A brief history of macroeconomics• Pre – Keynes: Say’s Law Automatic adjustment to full employment• Keynes: Animal spirits Excesses Inherent instability
Minsky, JMK, Stabilizing an Unstable Economy, Can “It” Happen Again?• Hicks: IS – LM Keynes without animal spirits
• Consumption function – Liquidity preference function• Hydraulic Keynesians
• Original Phillips Curve Policy Menu• Friedman: Monetarist counter-revolution
• Dispense with money illusion/enter expectations/natural rate Wage Setting: W = PeF(u,z)
• New Classical Economics• Rational expectations• Real business cycles (dynamic stochastic general equilibrium)
• New Keynesian Economics• Rational expectations – but sticky adaptation
Akerlof and Shiller: Prescription for Today• A Second Target – A Credit Target
“It is fairly easy now to project the fiscal and monetary stimulus necessary for aggregate demand to be at full employment—if financial markets are freely flowing…But, with the loss of confidence in the financial sector, macroeconomic planners must have a second target…—the amount of credit that would normally be given [to qualified borrowers] if the economy were at full employment.”
Methods: Discount window (TALF)/Capital injections/GSEs• Gotta replace the fallen Humpty-Dumpty (Securitization)
• A Credit Target—Whom to credit?• Bernanke and Blinder (1988) Credit, Money and Aggregate
Demand, AER, May.– In liquidity trap, expansion of credit is effective stimulus
Aside: Also in AER, May 1988. Akerlof and Yellen, Fairness and Unemployment“…where it is advantageous to pay some employees highly, it is also … fair to pay
other employees well.” Unfair pay shirking
Back to Minsky – Keynes • Variables:
PK = volatile demand price of kapital asset PI = sluggish supply price of investment goodsq = expected quasi-rent from the assetM = quantity of money ease of creditc = cash-flow commitment from finance arrangementsĉ = “acceptable” cash flow commitments
Then, PK = K(q, M, ĉ – c)“If the demand price of a capital asset … is not less than its replacement
costs, new investment will take place.”
