The bad news

2

• Homes: U.S. home prices have fallen 27% since peak. Pending sales fell 7.7% in January (though up slightly in west.)�

• 2008 CPI: Full-year changes of +0.1% overall, +1.8% core. Dramatic deceleration Q4 due to falling aggregate demand.

• March unemployment rate now at 8.5%,

• Manufacturing-Activity Index: Currently at 28-year low.

• Stock market: Down by 45% from peak.

• Bottom Line: The financial crisis contributed to an already weak U.S. economy that officially entered a recession in 12/07. As of April, it is now the the longest U.S. recession since the Great Depression.

What happens in a recession?

• Delay everything that can be delayed

–Business investment

–State and local spending (due to tax receipts)�

–Consumer durable purchase

–However, “consumer staples” usually see much smaller hit

•Government actions

–Want to avoid downward spiral

•Drop in demand … lay off workers … spending falls

•Need to stabilize demand: consumption, govn't, investment

–Trying a multipronged attack

Signs of hope

• Good news?

• Macroeconomics

–Financial situation stabilizing

•Particularly important for this recession

–Market volatility coming down

•VIX index – volatility index though back up again recently

•Ted Spread – gap between LIBOR and T-bill rate

–Keep a close eye on these metrics, as they are good leading indicators

Two sectors to watch: Real Estate and Autos

• Mortgage money available

• Auto loans to follow

• Real estate shows signs of stabilizing

– Queries showing usual seasonal uplift

– May see further activity in Spring

• Automotive sector is depressed

– Expect to see very attractive terms offered

– Also typical seasonal uplift

Implications for retail

• Q1 has been slow, but not as bad as Q4 for economy

–Impacted verticals–Real estate, auto, appliances, furniture, travel, luxury items

–Less sensitive–Low end shopping, health, local spending

•Areas to watch as leading indicators

–Automotive, real estate

–TED spread = 3 month Treasury bill rate – 3 month LIBOR

–Watch the VIX!

•Consumers are hunting for value

–Classic, reliable, solid...

Everybody talks about the economy...

• Can Google queries help forecast economy activity?

•Government data released with a lag

•Google data is real time

•Appears to be correlated with current level of activity

•May be helpful in “predicting the present”

•This is still 4-6 weeks before official data release

Model with Panel Data

Model:

log(Yi,t) = 1.681 + 0.3618 * log(Yi,t-1) + 0.4621 * log(Yi,t-12)

+ 0.0014 * Xi,t,2 + 0.0020 * Xi,t,2 + ai * Makei + ei,t

ei,t ~ N(0, 0.14972) , Adjusted R2 = 0.9791

Yi,t = Auto Sales of i-th Make at month t

Xi,t,1 = Google Trend Search at 1st week of month t and from i-th make

Xi,t,2 = Google Trend Search at 2nd week of month t and from i-th make

Makei = Dummy variable to indicate Auto Make

ai = Coefficient to capture the mean level of Auto Sales by Make
