Understanding the Great Recession
1
Using macro to understand the current recession
Let’s analyze the history of the recession to illustrate some of the major
macro issues/tools
Underlying forces:
1. Increasing leverage with lower perceived risks
2. The housing bubble and …. not “pop” but “hissssssss”
3. A “run on the shadow banks” and the Lehman bankruptcy
4. The crash in asset prices in 2008
5. Huge decline in wealth, leading to declining housing I and C.
6. International transmissions
7. IS-MP curve interpretation
8. Liquidity trap!
9. Governmental response in monetary and fiscal policies
10. The trough in late 2009
11. The long stagnation is still with us ….

Trends in volatility of US stock prices
Historical lows
Note: Implied volatility is a measure of the equity price variability implied by the market prices of call options
on equity futures. Historical volatility is calculated as a rolling 100-day annualized standard deviation of
equity price changes. Volatilities are expressed in percent rate of change. VIX is CBOE index.

Bank runs
Series of bank runs.
Different from earlier (Depression era) because was the run
by large depositors (run on the repo).
Bear Stearns and Lehman were wiped out in a week.

Bank losses*
* Note that US bank equity was around $1000 billion in 2010.
15
The Lehman Bankruptcy
A central event in the crisis.
Market fundamentalists worried that continued bailouts would
lead to “moral hazard” and worse future problems.
So on September 15, 2008, government decided to let Lehman go
bankrupt.
Catastrophic results:
- markets froze up (people could not make transactions)
- stock market went down 30 % in a month and US dollar ROSE
almost 20 %.
- “market fundamentalism lasted only 36 hours”
- then bailout of AIG, Citibank, BofA, TARP, GM, etc.
“An economy in free fall” in late 2008.

Risk on Mature Govt Debt (US, etc.)
CDS = risk that security will default. These are US and similar Treasury bonds! 17
A risk measure on commercial paper
Source: Federal Reserve page on commercial paper. These are short-term promissory
note or unsecured money market obligation, issued by prime rated commercial firms
and financial companies. This shows medium-grade (A2/P2) minus top grade (AA).
18
Policymakers respond
Panic of 2008: Financial markets hysterical; paranoia
everywhere about who was responsible and who should
pay.
Bush/Paulson: reluctantly saw that financial markets were
freezing up (Bernanke key to understanding this).
TARP: Started as buying toxic assets, then saw the light
and recapitalized banks.

Macroeconomic impacts
Rewrite augmented IS and MP curves as follows:
IS: Y = C(Y,W) +I(rb) + G + NX(Y,Yw)
Y = C(Y,W) +I(i - π + σ) + G + (X – M)
MP: i = f(Y, π)
rb = risky real rate = i - π + σ, where σ is the risk premium
Have adverse IS shifts to W, σ, and NX from Yw
Fed lowers i in standard manner, but real interest rate for
businesses goes up!
MP = Taylor rule

Lessons on the recent financial crisis
• Even with modern macro, globalized mature market
economies are subject to major risks; business cycles
have not disappeared.
• We are unlikely to reach full employment before 2016.
• Financial systems are inherently fragile because of their
maturity and liquidity transformation (K to M).
• Markets cannot manage themselves.
• The liquidity trap is a particularly nasty outcome
because monetary policy weak and fiscal policy
hampered by large deficits.
• The US benefitted from wise leadership this time. It
could have been much worse.
