2.2.1
How is the Nobel Prize in Economic Sciences Awarded?
The
Nobel Prize is perhaps the most globally recognized honor in each of the
fields in which it is presented. To find out what a challenge it is to
obtain, you can go to the official web
site, or keep reading! The Nobel
Internet archive is also a great resource.
Each year the category
committees send individual proposals to thousands of scientists, members
of academies, and university professors in numerous countries, asking
them to nominate Nobel Prize candidates for the coming year. Those considered
competent by these committees to submit nominations are chosen in such
a way that as many countries and universities as possible will be represented.
The process is very rigorous. Nominations received
by each committee are then evaluated with the help of specially appointed
experts. When the committees have made their selection among the nominated
candidates and have presented their recommendations to the prize-awarding
institutions, a vote is taken for the final choice of Laureates.
The Bank of Sweden
Prize in Economic Sciences in Memory of Alfred Nobel is awarded at the
Prize Awarding Ceremony at the Concert Hall in Stockholm, Sweden, on every
December 10th, the anniversary of Alfred Nobel's death.
2.2.2The University of Chicago, CRSP, and the Stock Market
In
addition to the Nobel Laureates who have studied the stock market,
thousands of academics also perform sunstantial and significant research in this area.
The University of Chicago is the leading institution of learning in
stock market research. In fact, twenty-three
of todays forty-nine Nobel Laureates in Economics attended or
taught at the University. This is an impressive forty-five percent
of all Nobel Laureates in Economic Sciences. The next largest cache
hails from Harvard with four Nobel Laureates. As of 2007, The University of Chicago list for Nobel Prizes in
Economic Sciences
inclues:
Edward C. Prescott, 2004, James J. Heckman, 2000, Daniel L. McFadden, 2000, Robert A. Mundell, 1999, Myron S. Scholes, 1997, Robert E. Lucas Jr., 1995, Robert W. Fogel, 1993, Gary S. Becker, 992, Ronald H. Coase, 1991, Merton H. Miller, 1990, Harry M. Markowitz, 1990, Trygve Haavelmo, 1989, James M. Buchanan Jr., 1986, Gerard Debreu, 1983, George J. Stigler, 1982, Lawrence R. Klein, 1980, Theodore W. Schultz, 1979, Herbert A. Simon, 1978, Milton Friedman, 1976, Tjalling C. Koopmans, 1975, Friedrich August von Hayek, 1974, Kenneth J. Arrow, 1972, and Paul A. Samuelson, 1970.

Why is the University
of Chicago so obviously prominent? In 1959, Louis Engel, vice president
at the firm then known as Merrill Lynch, Pierce, Fenner & Smith made
a phone call. He asked Professor James H. Lorie whether anyone knew how
well most people performed in the stock market relative to other investments.
Unable to answer the question, Lorie was intrigued. He proposed that Merrill
Lynch fund a project with the purpose of gathering, cleaning, and completing
the prices, dividends, and rates of return of all stocks listed on the
NYSE. Lorie would utilize the new capabilities offered by computers in
developing a database to maintain accurate securities information over
time. With a complete and accurate database, researchers would no longer
need to compile their own data. The project would prove invaluable to
empirical research.
CRSP
is an acronym for the Center for Research in Security Prices, which
is located at the University of Chicago. Established in 1960 with
a $300,000 grant from Merrill Lynch & Co., CRSP undertook the
massive data-gathering project. From 1964 to 1986, the Center received
gifts in excess of $1 million from those who yearned for the answer
as much as they did. James Lorie became the center's first director,
a position he held until 1975. He and Lawrence Fisher, former Associate
Professor of Finance and Associate Director of CRSP, collaborated
to gather the data. The two colleagues were faced with the monumental
responsibility of researching the accuracy of each piece of stock
information. They made use of their own formidable training and experience
to fill in the blanks for missing stock prices.
At
the end of four years, Lorie estimated that between two and three million
pieces of information were entered onto magnetic tape. Their stock market
database was completed in 1964. Lorie and Fisher analyzed total return,
dividends received, and changes in capital as a result of price changes
of all common stocks listed on the NYSE from January 30, 1926 to the present.
Lorie and Fisher published their findings in the Journal of Business.
The article proclaimed that the average rate of return on common stocks
listed on the NYSE was nine percent. For the first time in history, an
average rate of return could actually be measured. The front page of the
New York Times financial section heralded the pair's results.
However, the project really did not get to Mr. Engels question. Nearly four decades later, the average investors performance in the market was measured
by Dalbar, Inc. and was found to be significantly below the market average.
Over a seventeen year period ending in 2001, the average equity investor
only earned approximately 6% of the gain of the S&P 500.
CRSP continues to accumulate data on a regular basis. With a $180,000
grant from Dimensional Fund Advisors in 1984, data dating from January
1972 from NASDAQ markets was added. "If I had to rank events, I would
say this one (the original CRSP Master Fuel) is probably slightly more
significant than the creation of the universe," said Rex Sinquefield,
former co-chairman and current director of DFA. "The entire
field of finance has been changed and developed through that database."
2.3
Problems
2.3.1 Investors Rely on Lady Luck
The most significant
problem investors have is their reliance on factors other than empirical
research to select their investments. Investors are mostly speculating
and relying on Lady Luck rather than Nobel Laureates. They
are most often chasing the recent success of a manager, stock, time, or
investment style.
2.3.2
Active Investors are Unaware of Academic Studies
The great majority
of investors are unaware of the tremendous amount of academic brainpower
that has been applied to investing. This lack of awareness makes investors
more susceptible to the lure of active management, engaging in risks they
do not understand.
There is a stark contrast between a peer reviewed non-biased academic
paper and an article in The Wall Street Journal, Barrons, Forbes,
Fortune, Money, an analyst report, or the numerous other sources of investment
research. Virtually every private investor is unaware of the vast amount
of academic
research that points to investing in portfolios of index funds.
2.4
Solutions
The solution to the void of investor information is to take a quick walk
down the timeline of modern finance. Beginning nearly 350 years ago, I hope this
story will lead recovering active investors to a more sound investing strategy--a diversified
portfolio of index funds.
2.4.1 Get to Know the Pillars of Wall Street
Modern economics
is built on the pillars of academic research, some of which have led to Nobel
Prizes. The following milestones demonstrate how strongly the creativity,
determination, and tireless research of thousands of individuals influenced
the development of the 12-Step Program to Index Funds.
1654
Blaise Pascal
Chevalier de Mere
The Early Attempts to Quantify Risk
Modern
finance began with the realization that risk needed to be measured and
managed. "The intelligent management of risk" can be traced
to 1654 during the Renaissance Period. This was a time of great discovery.
Centuries-old beliefs were constantly under question and reevaluation.
This time of rebirth challenged wizards, mystics, fortune-tellers, oracles,
and soothsayers, who were previously regarded as experts on predicting
the future.
One day in 1654, a French gambler named Chevalier de Mere and a mathematician
named Blaise
Pascal tried to predict
the future outcome of a game of chance.
They wanted to determine
how to divide up the stakes of an unfinished game, when one player was
slightly ahead. With input from Pierre
de Fermat, they developed the theory of probability. This theory is
the basis for the concept of risk management and modern finance. Years
later in 1952, Nobel Laureate Harry Markowitz embraced what a French gambler
had questioned in 1654 and converted it into the theory of Portfolio Selection.
His idea revolutionized the investment process!
1690
Edmund Halley Beginning
to Understand Risk Management
Edmund
Halley, the famous English astronomer who discovered Halley's Comet, began
work on a series of life tables in early 1690. A probability based life
expectancy could be derived from these tables, which later became the
blueprint for the life insurance industry. Techniques of risk management
were improved over the years, leading to one of the first commercial applications
by the English government. Government officials developed life expectancy
tables and sold life annuities, soon followed by marine insurance products.
Halleys work ultimately led to the founding of Lloyd's of London,
which originated in a tiny English coffee shop that Halley frequented.
These same principles of managing risk were later applied to the stock
market.
A critical element in the development of risk management was the
discovery of standard deviation and the bell shaped curve by Abraham de
Moivre in 1730. Francis Galton, cousin to Charles Darwin, proposed the
Theory of Regression to the Mean by 1875. This theory predicts that a
result will be closer to the "normal" or the expected average
over time.
1776
Adam Smith The Wealth of Nations In his 1776 landmark book, The Wealth of Nations, Adam Smith asserted that
capitalistic countries would prosper, while non-capitalistic countries would
not. His argument was based upon the concept of the invisible hand, the
idea that individuals who acted in their own self-interest would benefit
society as a whole. By allowing supply and demand to dictate prices, a
free market economy would ensure that resources are exchanged in the most
efficient manner. Similarly, index fund investing is based on the idea
that market prices adjust to reflect current market
conditions, and that speculating on future prices is a losing endeavor.
1830
Judge Samuel Putman
The Prudent Man Rule
In a case of alleged improper management of a trust account, Judge Samuel
Putman presided with a decision that has become known as the Prudent Man
Rule, still used today to establish proper guidelines for trustees. He stated,
"Do what you will, the capital is at hazard. All that can be required
of a trustee to invest is that he shall conduct himself faithfully and exercise
a sound discretion. He is to observe how men of prudence, discretion, and
intelligence manage their own affairs, considering the probable income,
as well as the probable safety of the capital to be invested." This
was one of the first authoritative and clear statements that risk has to
be considered along with return.
1900
Louis Bachelier
The Beginnings of Random Walk Theory
The
year 2000 marked the centennial of the Random
Walk Theory of stock market prices. One hundred years since the
theory's conception, the overwhleming majority of investors are still not
convinced that the markets move in a random fashion. Many scholars
confirmed and refined the research of Louis Bachelier, the hapless
unsung hero of financial economics. He wrote "The Theory Of Speculation"
in 1900 and presented it as his doctoral thesis to the faculty of
the Academy of Paris. Bachelier anticipated much of what was later
to become standard fare in financial theory: the random walk of financial
market prices. "There is no useful information contained in historical
price movements of securities."

As is typical with
great minds, his professors and contemporaries did not appreciate his innovation.
His thesis received humiliating marks from his professors, and he quickly
dropped into the shadows of the academic underground. After a series of
minor posts, he ended up teaching in an obscure French town for much of
the rest of his life. His valuable work was largely ignored until the mid-1960s when, now Nodel Laureate Paul Samuelson unearthed and elaborated on his findings.
MIT professor Paul Cootner published a 500-page collection of research reprints
on the randomness of the market in 1964. The Random Character of Stock
Market Prices contained the first full text English translation of Bachelier's
1900 thesis. Cootner delivered this accolade about Bachelier: "So outstanding
is his work that we can say that the study of speculative prices has its
moment of glory at its moment of its inception."
The Random Walk Theory describes the way stock prices change unpredictably
as a result of unexpected information appearing in the market. This "random
walk" of changing prices has created a misconception among investors
that stock prices change randomly for no rational reason. It is not the
changes in stock prices that are random, but the news that is random. News
is inherently unpredictable, or it would not be considered news. In reacting
rationally to new information, the stock prices look as though they behave
in a random fashion. Many others, including Paul Samuelson and Eugene Fama,
would later expand on Bacheliers work.
See these two informative articles (pdf format) on Bachelier: 1,

The English scientist Francis Galton, founder of the science of measuring mental faculties, discovered that the wisdom of the many is more accurate than the wisdom of a few. Galton arrived at this discovery in 1906 at a livestock convention where a crowd of about 800 was asked to guess the weight of an ox. Galton added up all of the guesses and calculated the average. The crowd had collectively guessed that the ox weighed 1,197 pounds, just a pound away from the actual weight of 1,198 pounds. While no one individual came as close to the actual weight, the collective crowd’s average estimate hit it almost spot on. From this, Galton concluded that a crowd of regular individuals making independent guesses based on their own independent experiences comes the closest to matching the performance of experts.
The world’s equity markets prove out Galton’s discovery. Millions of investors throughout the world contribute their independent estimates of a stock’s value, resulting in a price that is more accurate than any one individual’s guess. This is the primary reason why indexing works; the market’s price embodies the wisdom of the crowd as it reacts to the news about capitalism.
1932 Alfred Cowles
The Standard & Poor's 500 Index
In
1932, Alfred Cowles established the Cowles Commission for Research in
Economics with the motto, "Science is Measurement." He also
funded the Econometric
Society's journal,
Econometrica. (see these great papers) The Commission moved
to the University of Chicago in 1939 and later to Yale University
in 1955, where it was renamed the Cowles Foundation. Almost every U.S.
winner of the Nobel Prize in Economics has spent time with the Cowles
Commission.
In need of a measurement stick, Cowles created a market index in 1938,
which became the basis for todays Standard & Poor's 500 Index.
The goal was to establish a stock market index to represent the average
experience of stock market investors. After sweeping failures in forecasting
the 1929 crash, the prominent Colorado businessman and investment counselor
wanted to focus his considerable statistical skills on analyzing stock
market forecasters' ability to choose a portfolio that beats a market
average or index.
Cowles reviewed approximately 12,000 recommendations and four years of
transactions by twenty leading fire insurance companies and published
his results in a July, 1933 article titled, Can Stock Market Forecasters
Forecast? His conclusion was, "It is doubtful." His extensive
study of stock market data provided an early demonstration of the "random
walk" in stock price movements and the beginning of the Efficient
Market Hypothesis. Cowles published a follow-up
study in 1944, reviewing
6,900 market forecasts over a period of 15.5 years. Once again, he concluded
there was no evidence supporting the ability of the forecaster to predict
the future of the market. His
studies were the first of over 200 in the area of active manager performance
measurements.
Cowles determined that despite his research and the research of countless
others after him, investors would continue to listen to market forecasters,
because they truly wish to believe that somebody, anybody, knows what
the future will bring. Most people think that a world in which nobody
has a clue is genuinely frightening.

The motto "Theory and Measurement" was first adopted in 1952. It succinctly captures the mission of the Cowles Foundation, which is th development and application of rigorous logical, mathematical, and statistical methods of analysis in economics and related fields. This motto replaced the original Cowles Commission original motto "Science is Measurement," reflecting the importance of theory that became clear early in the history of Cowles. Over the years Cowles scholars have made important contributions to economic theory, to econometric theory, and to a broad range of fields of economics through work that combines economic models with statistical methods of measurement. The mission of "theory and measurement" is reflected in the broad range of Cowles activities today, including those of its four core research programs in Econometrics, Economic Theory, Macroeconomics, and Structural Microeconomics.

"Don't
bet the ranch.
Get more bang for your buck.
Maximize output relative to input.
Nothing ventured, nothing gained.
Diversify instead of striving to make a killing.
Don't put all your eggs in one basket; if it drops, you're in trouble.
High volatility is like putting your head in the oven and your feet in
the refrigerator."
These common sense
sayings capture the essence of Harry Markowitz's brainstorm, sparked one
afternoon as he sat in the University of Chicago library reading a book
about the current thinking of stock market investing. At 25 years old,
Markowitz thought investors should be equally concerned with the volatility
or risk of investments as they are with the return of investments. Thirty-eight
years later, this innovative, practical theory earned him the 1990 Nobel
Prize in Economics. This landmark contribution to the investment world
was first published in 1952 in an essay entitled, "Portfolio
Selection."
He later authored a book entitled, Portfolio
Selection: Efficient Diversification (1959).
Using several stocks
from the New York Stock Exchange, Harry Markowitz created the first efficient
frontier. The image below and to the left is reproduced from his book,
Portfolio Selection, Cowles Monograph 16, Yale University Press,
1959. It has a line going to the origin, because Markowitz was interested
in the effects of combining risky assets with a riskless asset: cash.
A more modern version of the efficient frontier is found above. Notice
that the axis labels have been reversed. (source: schwab.com).
The rollover image shows twenty index portfolios compared to 10 years
data on the only mutual fund managers with 20 years or more of tenure.
The theory developed
in Portfolio Selection was a theory for optimal investment in stocks that
differ in regard to their expected return and risk. Investment managers
and academic economists have long been aware of the necessity of taking
both risk and return into account. Markowitz's primary contribution consisted
of developing a rigorously formulated operational theory for portfolio
selection under uncertainty. His theory evolved into a foundation for
further research in financial economics. Markowitz was the first to place
a number on risk relative to investing. Risk was previously discussed
in general terms and based more on feeling or intuition. He was able to
quantify the "undesirable thing" an investor tries to avoid
by using a range of possible return outcomes, based on the past variability
of returns.
Under certain conditions, Markowitz showed an investor's portfolio choice
can be reduced to balancing two dimensions: the expected return on the
portfolio, and its variance or standard deviation. The risk of a diversified
portfolio depends not only on the individual variances of the return on
different assets, but also on the opposite movement of all assets. When
one asset class goes up, another goes down. The opposite movement results
in a higher return than if all of the assets go up or down together. He
said, "Diversification is both observed and sensible. A rule of behavior
which does not imply the superiority of diversification must be rejected
both as a hypothesis and as a maxim." At twenty-five, Markowitz already
knew that focusing on return without proper consideration of risk creates
portfolios that are less than desirable.
Markowitz's contribution extended to making the distinction between the
risk of an individual stock and the risk of a portfolio. He showed how
individual risky stocks lose much of their risk if combined with less
risky stocks in a portfolio. What is remarkable about Markowitz's discovery
is that an investor can reduce
the volatility of a portfolio and increase its return at the same time.
When Markowitz began to formulate his ideas in the 1950s, leading
investment guides recommended that an investor should find one stock with
the highest expected return, invest in it, and ignore all the others.
If investing involved no amount of risk, holding investments with the
highest expected returns would be a highly profitable idea. The experienced
investor knows that investing is full of risk. Risk essentially means
that more can happen than will happen, which adds great uncertainty to
investment decision-making. People do not expect to be in an auto accident,
but they invest in auto insurance because of the unpredictable possibilities.
People also do not expect a stock in their portfolio to decrease in price,
but it can and will at some point. If an investors portfolio is
diversified, then the loss incurred from that one stock will be insured
by other stocks that do not decrease in price. Markowitz knew that in
the real world, investors are not only interested in return, but they are
concerned with risk as well.
Markowitz concluded that risk is central to the whole process of investing.
He then wondered how to measure the appropriate amount of risk to undertake.
Markowitz came to realize the cruel truth of investing: investors cannot
earn higher returns without taking on greater risk, and the greater the
risk, the greater the possibility of loss. He set out to devise ways
to help investors apply tradeoffs between risk and return. Using mathematics
to solve the puzzle, Markowitz discovered a remarkable new way to build
an investment portfolio, which he called the "efficient portfolio.
It offers an investor the highest expected return for any given level
of risk, or the lowest level of risk for any given expected return.
1958
James Tobin,
Nobel Prize in Economics, 1981
The Separation Theorem
Harry
Markowitz was primarily concerned with the diversification of risky assets.
James Tobin added the concept of combining risk-free assets, such as cash
or bonds, with risky assets, such as stocks. His paper, "Liquidity
Preference as Behavior Toward Risk" appeared in The Review of Economic
Studies in February, 1958. The concept he described is known as the Separation
Theorem, because it separates Markowitz's approach from the completely
different decision of dividing up the whole portfolio between risky and
risk-free assets.
Tobin also performed an analysis of financial markets and their relationship
to expenditure decisions, debt decisions, employment, production, and
prices.
