The Internet and Financial Market Structure
William Wilhelm
Introduction
Financial markets provide for trade in information because
money is just a means of scorekeeping, a way of tallying the relative
purchasing power of individuals and organizations. It can be a physical
tally such as a coin made from rare metals or a paper claim on a government
or other reputable agent that is difficult to counterfeit. But records of
relative purchasing power also can be stored digitally as strings of ones
and zeros if the storage medium is secure.
Information generally is costly to produce but not to
reproduce. In fact, information is perhaps too easy to reproduce once it is
revealed, it is difficult to exclude others from further use of information.
When the value of information mainly is strategic, as often is the case in
financial markets, information producers have incentive to protect their
investment by holding their cards close to the vest. But doing so obstructs
trade and undermines the social interest in informationally efficient
markets. Financial intermediaries promote trade in financial markets by
balancing the tension between self interest and collective interests in
information.
Financial intermediaries endure a similar tension in their
dealings w ith one another. Competition among intermediaries traditionally
was fueled by the human capital of key families and individuals Morgan,
Rothschild, Goldman, etc. whose names still dominate the financial
landscape. Primitive information technology led early financial
intermediaries to form information networks by scattering human repositories
for information as widely as possible. 1 Fair dealing over time within the
network led to strong relationships bound by trust through which information
moved about more freely than it would have otherwise. Reputations and
relationships, the foundations for trust, likewise are composites of
information but information that is not so easily disembodied from its
originator you can't buy a reputation. Innovation flourished in the context
of close relationships and powerful intermediaries that tempered competition
and thereby protected easily copied ideas and products assuring at least a
fair return on investment.
The internet upsets this delicate balance. We may look
back on the internet as having punctuated the evolution of financial market,
but its effect will most likely be interpreted as different in degree not in
kind from the effects of motorized transportation, the telegraph and
telephone, low-cost computers, etc. The internet is just another
technological advance along a path where human capital is being transformed
and in some instances displaced by information technology that codifies what
previously was embodied in human intermediaries.
The tension between human capital and information
technology, however, has profound consequences for the organization and
management of intermediary firms. The small family partnerships that
dominated early financial markets provided an environment in which human
capital was nurtured and passed from one generation to the next. By
contrast, the modern financial firm depends far more on financial capital to
support the large-scale but low margin operations that remain when
intermediary functions are codified.
