2. In 2009, Larry Summers, former Secretary of the Treasury, observed that “in the past 20-year period,
we have seen the 1987 stock market crash. We have seen the Savings & Loan debacle and commercial
real estate collapse of the late 80’s and early 90’s. We have seen the Mexican financial crisis, the Asian
financial crisis, the Long Term Capital Management liquidity crisis, the bursting of the NASDAQ bubble
and the associated Enron threat to corporate governance. And now we’ve seen this [global economic
crisis], which is more serious than any of that. Twenty years, 7 major crises. One major crisis every 3
years.” How could this happen given the large number of financial and information intermediaries
working in financial markets throughout the world? Can crises be averted by more effective financial
analysis?
Financial intermediaries perform a variety of functions that are designed to mitigate problems in our
financial markets.
It is an interesting question as to why these various institutions failed to detect the problems underlying
the crisis identified by Larry Summers. One explanation is that they face their own conflicts of interest.
Auditors have certainly received criticism for audit failures. Some suggest that this arises because
A second potential explanation is that human beings are subject to behavioral biases that lead them to
make common mistakes. For example, most retail investors extrapolated performances at Enron, internet
stocks, and mortgage backed securities to conclude that these would continue to be terrific investments.
