My perspective on this interesting and stimulating paper by Raghu Rajan has been very much
influenced by observing Alan Greenspan's approach to the development of financial systems and their
regulation over the past eighteen years. I believe that the Greenspan doctrine, if I may call it that, has
I
reflected the Chairman's analysis and deeply held belief that private interest and technological change,
interacting in a stable macroeconomic environment, will advance the general economic welfare.2
Chairman Greenspan has welcomed the ability of new technologies in financial markets to
reduce transactions costs, to allow the creation of new instruments that enable risk and return to be
divided and priced to better meet the needs of borrowers and lenders, to permit previously illiquid
obligations to be securitized and traded, and to make obsolete previous divisions among types of
financial intermediaries and across the geographical regions in which they operate. At the intersection
of market developments and monetary policy, he has led the Federal Reserve's efforts to understand
the implications of changing financial technology, such as the growing ease of housing equity extraction,
and to use the newly available information about market expectations and the price of risk embodied in
market prices.
The Greenspan doctrine holds that these developments, on balance, improve the functioning of
financial markets and the real economies they support. By allowing institutions to diversify risk, to
choose their risk profiles more precisely, and to improve the management of the risks they do take on,
IThe views are my own and do not necessarily reflect other members of the Board or its staff. I thank
Athanasios Orphanides, Matthew Pritsker, Patrick Parkinson, and Vincent Reinhart, of the Board's staff, for valuable
comments.
2Chairman Greenspan has spelled out his views on markets and regulation in many places, and much of
what follows is my synthesis of this material. His remarks on "Government Regulation and Derivative Contracts" on
February 21, 1997 are an especially valuable source for his approach to government regulation of financial markets.

they have made institutions more robust. By making intermediaries more robust and by giving
borrowers a greater variety of lenders to tap for funds, these developments have also made the financial
system more resilient and flexible--better able to absorb shocks without increasing the effects of such
shocks on the real economy. And by facilitating the flow of savings across markets and national
boundaries, these developments have contributed to a better allocation of resources and have
promoted growth.
That is not to say that the Greenspan doctrine holds that private markets always get it right.
Prices in these markets are driven by the tendency of human nature to project the recent past--to
waves of complacency and gloom--and hence are subject to overshooting. And private parties, left
entirely to their own devices, do not always produce a market structure and market relationships
consistent with adequate protection of financial stability. However, the actions of private parties to
protect themselves--what Chairman Greenspan has called private regulation--are generally quite
effective. Government regulation risks undermining private regulation and financial stability itself by
distorting incentives through moral hazard and by promising a more effective role in promoting financial
stability than it can deliver.
In this situation, government regulation has a function but it should be based on clear objectives,
narrowly tailored to meet those objectives, and, given the iron law of unintended consequences, it
should be clearly superior to private regulation. Regulation can be justified if incentives for private
regulation are weak--perhaps because of other government programs, such as deposit insurance--or if
market participants are likely to be ineffective, as for example small savers and borrowers. Regulation
may also be justified to promote greater flow of accurate information to enable private participants to
-3-
make better informed decisions.
New technologies and changing market structures imply that regulation should be constantly
under review; at times rolling back regulation--for example, by lifting the Glass-Steagall restrictions on
banking organizations--will benefit competition and help the financial sector deliver services more
efficiently and effectively. Moreover, regulation itself can benefit from competition. Running regulated
and unregulated markets side by side gives people a choice of whether they want protection and helps
to constrain regulation. Some of the same purposes can be served by having multiple regulators for the
same function; in some circumstances, the possible adverse consequences of competition in laxity may
be smaller than the potential for regulatory conformity and regulator risk -aversion to impinge on
innovation and change.
The Greenspan doctrine has had a perceptible influence on the evolution of markets and the
regulatory structure that applies to them. Raghu Rajan voices some concerns about this evolution. In
particular, he posits that the shift from depository intermediation to professional asset management has
increased tail risk to socially excessive levels and has left the world more vulnerable to rare but
potentially very serious tail events; he suggests some ways in which regulation should be increased.
In assessing this argument, we might find it useful to separate the question of whether the world
is riskier from the question of whether systemic risk has risen. The increased ability to disentangle risk
and tailor risk profiles should mean that risk has come to be lodged more in line with investor appetites,
a change that has probably tended to reduce the price of risk and encouraged riskier capital projects to
be funded. But individual investors at greater risk need not imply increased systemic risk--fatter tails
and greater potential for losses feeding back on the macroeconomy.

In fact, industrial economies have been marked by much less variability in output and inflation
over the past twenty years. Many reasons have been given for this so-called great moderation, but
developments in financial markets have likely played a role in making the economy more resilient. As a
consequence of greater diversification of risks and of sources of funds, problems in the financial sector
are less likely to intensify shocks hitting the economy and financial market.
The experience of 2001-03 is instructive. Unusually large declines in equity prices and
increases in defaults and risk spreads--surely tail events by most definitions--reduced wealth and raised
the cost of capital but did not aggravate the downturn by impinging on the flow of funds. Financial
intermediaries were not so troubled as to cut off the provision of credit, and in any case, many
borrowers had alternative sources of funds.
In addition, we have not seen a clear upward trend in volatility of financial asset prices over the
past twenty-five years, as one might expect if herding had increased in importance. Judging from
options prices, market participants are expecting the volatility of financial asset prices to be damped in
the future; they are also requiring lower-term premiums for placing funds for longer terms.
I do not share Raghu's nostalgia for the systemic-risk implications of bank-dominated finance.
Old-style crises involving impaired depository institutions had substantial spillover effects; their repair
took time, during which economic activity was affected; and emergency measures to deal with them
often involved moral hazard because they were aimed at stabilizing ailing intermediaries. I think we
would all agree that the industrial economy that has suffered the greatest systemic strains from problems
in the financial sector in the past fifteen years is that of Japan, which remained tied to the commercial
bank model Raghu finds safest. The macroeconomic effects of new-style crises involving market
-5-
liquidity, as in 1998, or outsized movements in asset prices may be more readily cushioned by monetary
policies aimed at bolstering the general level of liquidity and reducing interest rates. Such policies also
carry less risk of increasing moral hazard.
Although investment managers receive substantial funds directly from households, many of their
counterparties are sophisticated investors in positions of fiduciary responsibility. In addition, most asset
managers are employees of institutions--mutual fund families, bank holding companies--that are in the
market for the long haul. It is not in their interest to reach for short-run gains at the expense of longer
term risk, to disguise the degree of risk they are taking for their customers, or otherwise to endanger
their reputations. I would expect these counterparties and employers to enforce compensation schemes
that foster their objectives. As a consequence, I did not find convincing the discussion of market failure
that would require government intervention in compensation. Moreover, compensation regulation is
likely to be easily evaded and fraught with risks of untoward consequences. One only has to recall the
congressional action of 1993 that, by imposing less-favorable tax treatment on some forms of executive
compensation, fostered the shift to stock options that in turn was thought to have contributed to some of
the transparency and corporate governance problems of the late 1990s.
Regulatory and supervisory systems do need to evolve to reflect the shift to market-based
transactions. As intermediation shifts from depositories, with their specialized knowledge of borrowers,
to markets, disclosure and transparency become more important to allow diverse private parties to
assess risk properly, exert appropriate discipline, and contribute to the efficient allocation of resources.
Greater reliance on markets also elevates the importance of the safety of clearing and settlement
systems. Private-sector participants have every incentive to demand these disclosures and to ensure
-6-
that their trades go through as contracted. But government may need to act in concert with private
parties to arrive at collective decisions that strengthen markets and reduce systemic risk but might not
be in the interest of individuals acting separately. And with more of the fluctuations in asset prices
passing through to a large number and wide variety of households, educating people to make informed
choices and protecting retail customers from abusive practices remain key governmental functions.
A particularly interesting strand of the debate about excessive risk-taking concerns the
interaction of monetary policy and perceptions of risk in financial markets. Some analysts are
concerned that several aspects of the conduct of monetary policy in the United States have induced
market participants to reduce their expectations about risk too far, setting up the financial markets and
the economy for an unpleasant and possibly destabilizing surprise.
In this view, the low short-term interest rates that policymakers have thought were required
over the past few years to meet macroeconomic objectives are said to have encouraged reaching for
yield--settling for risk compensation that the investors themselves view as probably inadequate but
which they feel compelled to accept, perhaps to achieve targeted levels of real or nominal returns. The
tendency of policy to react strongly to sharp declines in key asset prices, and thereby limiting the extent
of the decreases, has been thought to induce risk-taking by imparting an asymmetry to asset price
movements. Finally, a concern is that the fairly new practice of telling the public about our expectations
for the path of the federal funds rate may have given market participants a false sense of security about
the future path of policy.
These practices have been the result of a monetary policy focused on price and economic
stability over the intermediate term interacting with the particular characteristics of the economy. The
-7-
global decline of inflation and spending induced a global reduction in interest rates to unusually low
levels in recent years. Those low rates were, in fact, intended to stimulate risk-taking and investment
when private agents pulled back. The tendency for asset prices to fall more quickly than they rise has
largely produced the more rapid and noticeable response of stabilizing monetary policy to declines than
to increases. And the importance for economic performance of more-accurate expectations about
monetary policy, along with the unusually low policy rates, led the Federal Open Market Committee to
undertake a more extended discussion of its policy expectations.
To the extent that these policy strategies reduce the amplitude of fluctuations in output and
prices and contain financial crises, risks are genuinely lower, and that development should be reflected
in the prices of assets. To the extent that the central bank can convey something useful about its
intentions, markets that take account of these intentions will be priced more accurately.
The risk is that private agents overestimate the ability or willingness of central banks to damp
volatility in asset prices or the economy, or that they fail to appreciate that future policy actions depend
on an imperfectly predictable economic outlook. But developments should have partially alleviated
some of these concerns. Investors have had an opportunity to observe that policy actions in 1987,
1998, and 2001-03 cushioned the economy, but they did not stop major declines in the prices of equity
in 1987 and 2001 or of risky credits in 1998. Short-term rates have risen substantially in the past year,
reducing the profitability of "carry trades" without triggering an unwinding that drove long-term interest
rates higher or widened risk premiums. And expectations that policy tightening would remain gradual
over the near-term have not stopped long-term rates from fluctuating substantially in response to
incoming data; the movements of future or forward rates out the yield curve after surprises in data have
•
-8-
been at least as large since 2003 as they were before.
That is not to say that we have nothing to worry about. As I already noted, Alan Greenspan,
himself, has often been concerned about market complacency--as recently as his latest monetary policy
testimony. People may well perceive the economy as more stable than it is or central banks with
greater power than we have to smooth the economy or to foresee our own actions.
Clearly, reminders to the public of the inherent uncertainty in economic developments and
policy responses are appropriate and should have some effect. The question is whether these warnings
should be supplemented by actions to inject uncertainty into policy pronouncements by saying less than
we can or into the economy by shifting our objectives away from seeking the best outcome for the
economy over the intennediate tenn. In my view, such policies would result in less accurate asset
pricing, reduce public welfare on balance, and definitely be at odds with the tradition of policy
excellence of the person whose era we are examining at this conference.
