What will the future bring?
What will the future bring? -- A deep human
psychic need -- Material benefits allurement
If I were asked to guess what people are
generally most insecure about, I would say it is
the content of the future. We worry about it
constantly. -- Isaac Asimov

Weather forecasting
Evaluation -- Forecasts within one- to two-day
range lead time are reasonably accurate --
Long-range prediction remains the voodoo aspect
of weather forecasting
-- only forecasting profession that has shown
clear signs of improvement -- most successful of
all the future-predicting professions examined in
this book
8
From Meteorology to Economics
Why did God create economists?
In order to make weather forecasters look good

3 The Dismal Scientist
10
Economic forecasters
Who are they? -- Most influential economists in
the US Federal Reserve Council of Economic
Advisors (CEA) Congressional Budget Office
(CBO) -- International International Monetary
Fund World Bank-- Others Hundreds of private
organizations Media
11
Misleading Indicators
Conflicting economic religions Keynesians
government spending Monetarist supply of
money Neoclassicists - laissez-faire
commerce Marxist economists - controlled
economies First law of Economics for every
economist, there is an equal and opposite
economist
12
Misleading Indicators
Why economy is predictable Theory of General
Equilibrium economy is inherently
stable economy has natural forces to restore to
its equilibrium
Is this sound logic or wishful thinking?
13
Five sins
Economists cannot predict the turning points in
the economy
CEA
CBO

GNP growth and inflation from 1970 1974
1970 mild recession1972 recovery 1973 sharp
increase1974 deep recession

NBER
BEA
14
Five sins

Result Among forty-eight predictions,
forty-six missed the turning points in the
economy. Accuracy 15
Five sins
Economic forecast accuracy drops with lead
time The average forecast errors percentages
for real GNP growth are 45 at the beginning of
the year being forecasted and 60 six months in
advance of the year being forecasted. The
average forecast errors percentages for inflation
are 30 at the beginning of the year being
forecasted and 40 six months in advance of the
year being forecasted.
16
Five sins
Economists forecasting skill on average is about
as good as guessing.
-- Naïve forecast, best prediction is to assume
no change -- better in accuracy when predicting
highly volatile economic statistics, like
interest rates -- worse in accuracy when
predicting highly stable economic statistics,
like government spending -- as accurate as
economists when predicting a middle ground of
important statistics, like GNP growth and
inflation
17
Five sins
Increased sophistication provides no improvement
in economic forecast accuracy Large models with
over a thousand equations do no better than those
using simple models Educational and professional
sophistication have little to with economic
forecasting prowess. There is no evidence that
economic forecasting skill has improved over the
past three decades
18
Five sins
Forecasts may be affected by psychological
bias Overly optimistic Overly
pessimistic Economists forecasts merely reflect
their own psychological outlook on life.
19
Reason 1 -- Complexity
  • Complex Systems
  • No natural laws governing their behavior
  • Numerous interactions among the parts
  • Unexpected moments of self-generated turmoil
  • Adaptation to environments and evolution
  • No fixed cycles

20
Reason 2 Erroneous data
Crude, approximate, guessing data Irrelevant
data Questionable survey data Inaccuracy of
statistics (Unemployment rate, how many people
are seeking employment)

Random harvest
October is one of the dangerous months to
speculate in stocks.
The others are July, January, September, April,
November, May, March, June, December, August, and
February -- Mark Twain

Three strikes1- Stock prices
More elaborate methods Dow theory Elliot
Wave theory .
Astrology!!! Planetary alignments and lunar
cycles influence investor psychology
25
Three strikes1- Stock prices
However Past stock prices are useless in
predicting the stock market.Only 3 percent of
the total variation in daily stock prices is
explained by historical patterns, and the rest is
pure noise Millions of investors can respond
almost immediately to conduct online
transactions. The stock market is much more
dynamic and complex than the economy.
26
Three strikes 2 future earnings
Corporate earnings growth In a logical sense,
share prices are random, then their key
determinant future earnings should be random
as well
27
Three strikes 3 - EMH
EMH Efficient Market Hypothesis What is
it the stock market knows everything that is
knowable about future corporate earnings thus
prices all stocks at their true values
28
Three strikes 3 - EMH
Result Enormous amount of competition drive the
prices toward their true value. You cannot find
over or undervalued stocks ,and you can never
beat the market or predict it!

5 Checking the Unchecked Population
30
Return to glacier?
The ice age The ice age come in predictable
cycles and that we are overdue for one. On the
contrary Global warming caused by the
greenhouse effect
31
Malthusian
Most famous doomsayer - T.R.Malthus Population,
when unchecked, increases in a geometrical
ratio, while subsistence increase only in an
arithmetical ratio. Global Famine hunger -
starvation - widespread famine
32
Feast or famine?
Will there be feast or famine? For the
productivity of modern agriculture genetic
engineering Against cropland is
shrinking pollution is poisoning
aquifers insects are becoming resistant to the
chemicals breeding created farm animals and
plants are more genetically alike
No one knows
33
The Easter Island tragedy
Societal Collapse Mysterious stone
heads Polynesian on the Easter Island Are we
repeating the mistakes? our planets ecosystem
has obvious limits that cannot support the
exponential growth in human activity forever W
have no place to go unless escaping the earth
