Understanding the Great Recession

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 risks2. The housing bubble and …. not “pop” but “hissssssss”3. A “run on the banks” and the Lehman bankruptcy4. The crash in asset prices in 20085. Huge decline in wealth, leading to declining housing I and C.6. International transmissions7. IS-MP curve interpretation8. Liquidity trap!9. Governmental response in monetary and fiscal policies10.The trough in late 200911.The long stagnation is still with us ….

the run by large depositors (run on the repo).Bear Stearns and Lehman were wiped out in a week.

The Lehman Bankruptcy

A central event in the crisis.Market fundamantalists worried that continued bailouts

would lead to “moral hazard” and worse future problems.

So on September 15, 2010, 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 just 36 hours (!)- then bailout of AIG, Citibank, BofA, TARP, GM, etc.

“An economy in free fall” in the fall of 2008.

Risk on Mature Govt Debt (US, etc.)

Policymakers respond

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.

Panic of 2008: Financial markets hysterical; paranoia everywhere about who was responsible and who should pay.

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
