  Characteristics of 1930s Great Depression
-   Big credit bubble in 1920s - borrowed money to bid up stock prices
-   Nobody knew what was going on until a month into stock market crash
-   1920s stock market bubble CAUSED the 1930s Great Depression
-   Establishment of SEC and stock market regulations specifically designed to prevent another credit bubble

S&P 500 Price/Earnings Index - 		1881 to 2002
S&P 500 Price/Earnings Index - 1881 to 2002


  P/E Ratio measures price of stock vs historical earnings
-   Historical average around 13
-   Above 18: Stocks are expensive
-   Below 10: Stocks are inexpensive
-   Historically goes below 10 after exceeding 20
-   Predicts stock market fall of 50% or more

(Next slide) Greenspan and the Federal Reserve
Generational Economic Cycles


  Credit bubbles every 70-90 years (generational cycle) during 'unraveling' period
-   Credit bubble / depression creates a risk-aversive generation
-   New bubble when previous risk-aversive generation retires
-   Financial crisis and war crisis reinforce each other

  "Crusty Old Bureaucracy" theory
-   Informal (not rigorous) explanation
-   Every organization becomes bureaucratic in time - bankruptcy
-   Same rules applies to entire nation in 70-90 year cycles

Greenspan and the Federal Reserve


  Greenspan in 1997
-   Had referred to "irrational exuberance"
-   Knew that a stock market bubble was forming
-   Decided to deal with consequences rather than end bubble

  Federal Reserve after 2000
-   Prevent 1929 forced selling 'tipping point'
-   Reduced interest rates (overnight funds rate) to 1%

  Consequences of low interest rate
-   Housing bubble
-   High auto sales
-   Increased personal borrowing during unemployment
-   Extension of stock market bubble

  Medium range risks
-   Collapse of Chinese credit bubble
-   Oil disruption through Mideast war
-   Loss of confidence after terrorist attack
-   Cyclic downturn spiraling down

Technology cycles versus 		generational bubbles
Technology cycles versus generational bubbles


  Identifying technology cycles
-   Smooth the S&P index, ignoring bubbles
-   Cycle length 40-50 years
-   Technology (Kondratieff) cycles have been identified for hundreds of years

  Technology versus Generational cycles
-   Technology cycles are global, generational cycles are local
-   Entirely independent - can enhance or cancel each other
