Economic & Market Myths
• The 2008 crisis made it clear that
some of our assumptions about
economics and the markets are wrong.
• Crises are always a test of what we
know.
• It’s time for journalists to start writing
about our misunderstandings.
Markets are Efficient-Not!
• Information was not a variable in
classical econometrics.
• Assumption: Information spreads
uniformly to market players.
• If true, we’d be out of a job!
• Game theory, decision-making theory
make information a financial variable.
• See work of John Nash (Nobel winner),
Mandelbrot on fractal behavior.
Markets Are Rational-Not!
• Daniel Kahneman, Vernon Smith, 2002
Nobel Prize.
• Even with complete info, humans take
shortcuts, make bad assumptions.
• “It’s different this time.”
• Housing prices will rise forever!
• See patterns where none exists.
• Game theory applied here, too.
Self-Regulation Works-Not!
• Rollback of key laws helped crisis occur.
• Until 1999, U.S. banks restricted in their
ability to speculate in markets.
• Glass-Steagall suspended.
• Derivatives deregulated.
• Basel rules of BIS: a disaster so far?
• Ratings agencies: a joke.
• How to regulate without killing
innovation?
Formulas Can Set Values-Not!
• Long-Term Credit Management failure.
• Myron Scholes & Robert Merton.
• Nobel Prize for derivative valuation.
• Lost $4.8 billion in 1998, saved by Fed.
• No market, no good valuation.
• Current ABS, swaps, etc.: no market.
• Buffett: “If you want to know what.
something’s worth, sell a piece of it.”
Economies Can Be Guided-Not!
• Greenspan on current crisis: I was
wrong.
• Central banks try to smooth cycles.
• The cycle seems to always reimpose
itself, as now.
• Too many variables.
• No global regulators-nations at odds.
• Current protectionist problems.
Assets Uncorrelated-Not!
• Modern portfolio theory: reduce risk by
having uncorrelated assets.
• Mix of stocks, bonds, commodities, etc.
• Sometimes everything moves together.
• Gold and dollar tracked each other.
• Treasurys and gold tracked.
• Gold and oil delinked.
• See William Sharpe, Stanford economist.
Spread Risk, Reduce It-Not!
• CDOs spread debt risk among thousands
of buyers. Supposed to cut risk.
• Hasn’t worked.
• No one can tell what’s inside them.
• Rating agency formulas useless.
• Buyer’s strike closes down market.
• Spreading risk did not affect collapse
of these instruments.
“Buy and Hold” Works-Not!
• “Secular uptrend” is REALLY long-term.
• 10 years of gains wiped out.
• Traders, short-sellers, market timers
have lower losses, some gains.
• Mutual fund (unit trust) managers have
failed their clients.
• Long term works only if you never die!
• What will replace this strategy?
Economics Gets All Costs-Not!
• “Mechanism design theory.”
• Externalities: not in the equation.
• Tribal people, laid-off workers,
carbon emissions.
• Supply, demand & those who get
screwed out of the equation.
• See Hurwicz, Maskin, Meyerson, 2007
Nobel Prize.
Capitalism=Democracy-Not!
• Noncapitalist countries have had fastest
growth rates for years.
• Singapore, China are stark examples.
• Commission on Growth & Development.
• High growth: credible government, high
savings rate, played into world economy,
stability, flexible home markets.
• Most not democracies; China is model?
Euro Crisis: More of Same
• Greece: Failure to observe Euro rules,
low economic output, low exports.
• Spain: Real estate bust, weak banks.
• Italy: Huge debt, inadequate revenue.
• Continuation of 2008 crisis.
• QE everywhere.
• Governments resist fiscal measures.
• Rest of world beginning to falter?
Let’s Report It
• Much of our reporting has latent, untrue
assumptions.
• Challenge sources on markets.
• Reinforce uncertainty—the real state of
things
• Report, write what you don’t understand.
