GLOBALIZATION TOWARD SUSTAINABILITY"

International Conference on Concerted Strategies to meet the
Environmental and Economic Challenges of the 21st Century
Club of Rome
Vienna, Austria,16 and 17 April, 2009
The London G-20
Summit, April 2nd, marked a useful new beginning for multi-lateralism.
The eclipsing of the G-8 was as necessary for the world as the new
informal proposals by China, India, Russia and Brazil for a new global
reserve currency to complement the US dollar and the euro. Just as
important were the promises to democratize the World Bank and the IMF
and to tighten supervision and regulation of markets and finance. The UN
Commission, co-chaired by Joseph Stiglitz and Amartya Sen, both Bank of
Sweden prizewinners, went further in advocating for a new global reserve
currency as Special Drawing Rights (SDRs). UNEP, UNDP and the ILO broke
new ground by launching their Green Economy Initiative in Geneva, Dec.
1st, 2008, at which I presented a keynote.1
However, all these
useful proposals are still within the traditional framework of
economics. A multi-disciplinary, systems approach is required to address
three key issues still considered sacred cows: 1) GDP-measured economic
growth; 2) free trade and its nemesis "protectionism" and 3) the need to
redesign money systems whose circuits are now overloaded and augment
them by taking advantage of pure information-based exchange now offered
by information technologies and the internet.
Our Club of
Rome and GLOBE colleagues have sought valiantly to place these three
sacred cows on international agendas for decades. My "Ecologists versus
Economists" article ran in the Business Section of the New York Times in
1971, based on a speech I gave to the National Association of Business
Economists and my "New Models for Managing Steady State Economics"
followed in the Financial Analysts Journal in May 1973! Yet, after
millions of words by so many of us, these topics are still taboo among
the mainstream economics profession and media. As another example, I and
physicist Fritjof Capra have authored another paper, "Qualitative
Growth," covering these taboo issues.2 So far, it has been rejected by
many of the mainstream journals in the USA.
So, we still have much
work to do in forcing these deeper, paradigm issues into mainstream
debates, the G-20 as well as all other major UN forums and agencies, as
well as into legislative bodies. Our Club of Rome co-sponsorship of the
BEYOND GDP conference in the European Parliament, November 2007, in
which I was honored to represent our organization has produced some
fruit (www.beyond-gdp.eu). The issue received support by MEPs, press
coverage, and a GlobeScan survey in 10 countries3 that found huge
majorities of people favoring the overhaul of GDP to include statistics
on health, education, poverty gaps and environment funded by my company
(see www.ethicalmarkets.com and www.globescan.com). So, we must keep
educating media, politicians business people and academicians on the
need to correct GDP since its faulty formula still steers societies into
ever worse social and environmental losses and worsens climate change.
The second sacred cow – "free trade" - has a deep hold on leaders
from the IFIs, G-20, most in the UN and even the Obama administration in
the USA. But, it can now be questioned as part of the ideology of
laissez-faire, "Anglo-Saxon" economics that has so spectacularly failed
in the meltdown of the global casino it encouraged. Kneejerk
pronouncements against "protectionism" betray the sterility of this
"free trade" ideology. Sovereign nations have every right to protect
their citizens and their environments from predatory finance and
exploitation of global corporations. Free trade ignores social and
environmental costs, still treated as "externalities" in WTO rules.
Corrections to GDP-growth accounting as well as to corporate balance
sheets by incorporating ESG factors would reveal the truth that local
and regional trade of goods is more efficient. Keynes was correct that
it its more efficient to trade recipes than ship cakes and cookies
around the world.
With corrected national accounts and honest
corporate accounting, world trade can be ephemeralized and
dematerialized toward useful services. These will not include the
metastasizing of bogus financial services that caused the current
meltdown of the global casino. Useful services include recipes for
greener technologies, proven formulas for delivering healthcare,
education and social services with successful outcomes in various
countries. For example, the USA might learn from European countries how
to cut 50% of the waste from its medical-industrial complex with better
outcomes; how to run elections from Canada, Brazil and other
democracies; how to reduce its prison populations, now almost five times
the world average; how to deal with drugs and other social technologies
such as Mexico's and Brazil's contingency currency transfers (CCTs).
Other countries can learn from the USA how to encourage entrepreneurship
and sensible risk-taking – not the reckless kind from Wall Street! As
world trade evolves into exchanging what works, as well as continuing to
savor and trade cuisine, art, music, dance and literature, world trade
can actually help our human family evolve toward higher levels of
planetary awareness and the earth ethics embodied for example in the
Universal Declaration of Human Rights and the Earth Charter (www.earthcharter.org).
Trade in material goods can be limited to those very rare mineral
resources and goods needed for essential production or facilities. I was
asked by Brazil's SEBRAE trade group of small businesses to spell out
some of these paths to sustainable world trade in 2002 (see
Figure 1 and
Figure 2).
A persistent problem is that too many economists still
dominate policy options. For example, the Obama Administration, due to
the money and influence of Wall Street, has hired a group of economic
advisors deeply implicated in the financial meltdown. All have Wall
Street connections. Robert Rubin, former Goldman Sachs CEO and US
Treasury Secretary (known as "Mr. Leverage"!), is the mentor of Lawrence
Summers, Obama's chief economic advisor, and Timothy Geithner, now
Obama's Treasury Secretary who, with Henry Paulson, oversaw the Bush
bailouts of Wall Street firms in 2008. Then chair of the New York
Federal Reserve, Geithner did nothing to raise alarms at financial
abuses. Now, he protects Wall Street with his new Public-Private
Partnership Investment Plan which subsidizes hedge funds and private
equity firms to "buy" the banks' toxic assets. I agree with Joseph
Stiglitz and former IMF chief economist Samuel Johnson in the Atlantic
Monthlyy, May 2009, that no more taxpayer money should be given to these
banks that are still seen as "too big to fail." Instead, they should be
taken over by the FDIC and broken up, allowing the shareholders and bond
holders to take the losses.
Thus, even with the more progressive
approach of President Obama and the new "buy-in" by the G-20 to the
language of the green economy and climate change, we still have work to
do. First, we need to help expose the financial oligarchies described by
Simon Johnson, which operate in all countries, due to financial
globalization and the influence of bloated financial sectors and their
money which corrupts politics everywhere. Even the G-20s vows to "name
and shame" tax havens and the Financial Stability Forum of the OECD
countries is hypocritical since the USA and the UK still allow such
secret activities within their borders.
US citizens feel betrayed by
Wall Street and their trust has been shaken. The European leaders cited
the need for new regulatory action to curb speculation, leverage, hedge
funds, private pools of capital and derivatives such as the some $60
trillion of credit default swaps which played a key role in the turmoil.
The total of credit and derivatives contracts is estimated by the Bank
for International Settlements (BIS) at $683 trillion,4 while global GDP
measures only $62 trillion.
The disgraced Wall Streeters and other
financial players in the global casino are still in denial that
financial sectors, particularly in the USA and Britain had metastasized
to some 25% of their GDPs. By 2007, the financial sector of the US
economy peaked at 40% of GDP! Switzerland is in a similar condition,
while the fate of Iceland looms as a lesson. An efficient financial
sector should comprise much less than 10% of a country's GDP. The issue
is how to downsize and deleverage all those illusory gains that have now
become illusory losses that have corrupted money systems on which real
productive sectors have come to rely. The power struggles concern who is
going to take the losses: the players themselves who profited on the
upside, the shareholders and bond holders – or taxpayers? So far, in the
USA, due to the powerful Wall Street lobby's influence in Washington,
the taxpayers are taking the hit. So much trust has been lost that
President Obama has inherited a poisoned chalice.
The 2009 report of
the private Group of 30 elite financiers, chaired by former US Fed
Chairman Paul Volcker, stuck to a familiar list of reforms of global
financial architecture: more coordinated, transparent, international
regulation, standards, governance and accounting practices, as well as
limits on leverage, compensation and perverse incentives for
risk-taking. This Group of 30 representatives from Citibank, Morgan
Stanley, JP Morgan Chase, AIG, Merrill Lynch and other now-humbled
firms, has been studying the explosion of exotic derivatives for some
two decades but has offered little useful advice other than calling for
clearinghouses for over-the-counter contracts such as credit default
swaps.5
An important underlying issue is how capitalism itself must
evolve. The US-led model of economic growth, as measured by
money-denominated GDP (see Figure 3, GNP Problems), the so-called
“Washington Consensus" of free markets and trade, open capital accounts,
floating currencies, privatization, all dominated by mostly un-regulated
global financial markets, has now clearly broken down. China led the new
debate by calling its summit meeting in Beijing in late October, 2008,
attended by all the European countries, as well as the G-20 and other
African countries as well. The Bush administration's disdain for such
multi-lateralism left the USA way behind the curve, not invited to such
important gatherings, including the Shanghai Cooperation Organization
which includes Asian and Central Asian countries, including Iran.
Meanwhile China has formed close alliances worldwide, particularly with
Europe, African countries and those in Latin America. The new G-20
demands for fairness include democratization as well as expanding the
United Nations Security Council to include permanent membership for
Brazil, Japan, India and important countries of the South, such as
Indonesia and South Africa, including scrapping the veto still wielded
by the old “permanent five" victors of World War II.
All this is a
rude awakening for many in the USA. At least the Obama team is reversing
the Bush administration's ignoring of other countries’ interests and
going it alone. Today, most US citizens now realize that we need the
world and the United Nations and that, indeed, the global financial
crisis which began on Wall Street now requires global cooperation to
solve. This is the true dimension of change that President Obama must
now face. Former Assistant Secretary of the Treasury under Ronald
Reagan, Paul Craig Roberts, warns President Obama that the Bush bailouts
and the new $1 trillion-plus recovery plans must take a new course if
the US dollar's value is to stabilize. Roberts warns that the $
trillions spent on fighting Bush's unnecessary wars in Iraq and
Afghanistan will bankrupt the fragile US economy and urges Obama to end
both these senseless occupations.6 Joseph Stiglitz estimates the Iraq war
alone will cost $3 trillion,7 and in a recent editorial called for the US
to take over its large, insolvent banks.8
G-20 promises to reform
the un-regulated global casino must be addressed promptly if further
harm to the innocent, poor and vulnerable is to be prevented.. The
Communiqué from the G-20's London summit clearly cited increased
cooperation between nations as essential, particularly oversight of
global banks and other financial players. Cooperation is necessary to
avoid “beggar-thy-neighbor" policies trying to advantage any one
country, but this no longer can be couched in old "free trade" slogans.
As noted, countries have rights to protect their citizens from private
sector exploiters without being accused of "protectionism." British
Prime Minister Gordon Brown suggested a "global collegium of
regulators." However, no mention was made of the most urgent priority:
to tackle the up to $3 trillion of daily currency trading, over 90% of
which is speculation. Bouncing currencies have led to much of the
turbulence and excessive volatility in world markets as “contagion”
spreads in minutes in this 24/7 around-the-clock trading. A small, less
than 1% tax on all trades has been advocated since the 1970s when it was
proposed by economist James Tobin and in 1989 by former US Treasury
Secretary Larry Summers.9 Not only would this reduce speculation, but it
would raise over $300 billion annually to meet UN Millennium Development
Goals and fund needed public goods.
Such a currency-exchange tax
would be simple to collect using a computerized system which can be
installed on trading screens, such as the Foreign Exchange Transaction
Reporting System (FXTRS).10 This system operates like an electronic
version of Wall Street’s venerable “uptick rule," enacted in 1934 but
repealed during the Bush II administration. Today’s Wall Street traders
themselves are calling for its re-instatement to curb naked
short-selling. The FXTRS computerized “uptick rule" gradually raises the
basic, less than 1% tax whenever a bear raid starts attacking a weak
currency. Such bear raids are rarely to “discipline” a country’s
policies, as traders claim, but rather to make quick profits. In the
transparent FXTRS system, traders selling falling currencies begin to
see that the rising tax is cascading into the country’s currency
stabilization fund and cutting into their gains. Seeing no further
profit, traders can voluntarily exit the market and search for some
other currency or arbitrage opportunity. The funds collected from such
currency exchange taxes would, along with another issue of special
Drawing Rights by the IMF, raise hundreds of billions of dollars (see
FXTRS.)
The 800-pound gorilla still
not acknowledged is the need for monetary reform of fractional reserve
banking itself, which allows banks to create most of a nation’s
money-supply as debt – out of thin air. Restoring the right of
democratic nations to coin their currency directly (as required in the
US Constitution) is now essential, particularly in the USA where debt is
now crushing every sector and the Federal Reserve along with the
Treasury are now printing money in clear sight of taxpayers. In Britain,
there are many such proposals for reforming the Bank of England,
including those of the New Economics Foundation, banking experts James
Robertson and those of Canada's Committee on Monetary and Economic
Reform (www.comer.com). The American Monetary Institute has introduced a
bill in the US Congress to achieve the gradual change needed in our
banking system (www.monetary.org).
The market-fundamentalists
abetted by the economics profession and the Bank of Sweden have waged a
30 year campaign to portray economics as a science. They succeeded in
persuading the Nobel Committee to set up a $1 million prize in the 1960s
with the late Milton Friedman of the laissez-faire Chicago School as its
early recipient. This so-called Bank of Sweden Prize in Economic Science
in Memory of Alfred Nobel is now being criticized by many, including
Nobel's heir, lawyer Peter Nobel, Nassim Nicholas Taleb, author of The
Black Swan (2007), myself and many mathematicians including Ralph
Abraham, Benoit Mandelbrot and other scientists.11 Too many of these
subsequent Bank of Sweden "Nobel Memorial" prizes have been awarded to
laissez-faire economists, particularly those whose research purported to
prove (using specious mathematics) why central banks must be free of all
political control – even by the most democratically elected governments.
Today we see central bankers out of control, printing money, awarding
favored treatment to large banks, reckless insurance companies like AIG,
and claiming the privilege of secrecy. The US Federal Reserve Board even
refused Freedom of Information requests by Bloomberg, Fox News and other
media with questions as to which companies have been so favored and by
how much. Now that the US Treasury is at last disclosing where the first
$350 billion of TARP funds went, perhaps the Fed will follow suit. AIG
was allowed to funnel this money bck to its counterparties, paying off
their bets (CDSs) at 100% on the dollar to Goldman Sachs ($12 billion)
and other Wall Street firms, as well as Deutsche Bank, UBS, Credit
Suisse and other European banks.
More fundamentally, the failures of global monetary systems are
rooted in the expansion of human knowledge and innovation as we
transition from the early fossil-fueled Industrial Era to the cleaner
technologies of the information-rich Solar Age. Just as the gold
standard failed to provide enough “bandwidth” for all the growth,
innovation and new communication and transactions of the Industrial Age,
so today’s money circuits cannot provide enough bandwidth for the
greatly expanded communications and trading of today’s growing
Information economy (see Figure 4).
The disruptive
technologies rapidly displacing those now unsustainable, polluting
Industrial Age technologies have already burst out of the existing money
circuits and narrow central banking regimes. Money is merely one form of
information, and now the pure information-trading platforms are
providing the needed extra bandwidth for trading, including that
exclusively for socially and environmentally responsible investors and
companies helping grow the green, sustainable economy world wide (see
Ethical Markets' Advisory Council which includes leaders of the Calvert
Group, the Social Investment Forum, Green America, Innovest Strategic
Value Advisors, Capital Missions Company, the World Business Academy and
Iowa Progressive Asset Management, the leading US broker-dealer firm for
socially responsible investing. Many, including Ethical Markets Media,
LLC, are signatories of the UN Principles of Responsible Investing,
which represents pension fund and other institutional asset managers $15
trillion under management.
Beyond securities trading on secure
internet platforms like Archipelago, Instinet and such networks as
Entrex for private companies, Wall Street Without Walls, Prosper.com,
Zopa.com in Britain, Qifang.ch in China and others, we have seen the
explosion of internet trading (B2B, peer-to-peer, C2B, etc.) since 2000.
They include such major companies as e-Bay, Google and Amazon, social
networking sites like MySpace, Facebook and LinkedIn, as well as all the
new electronic barter and gifting sites, Craigslist, Freecycle, Global
Giving, Green Grants as well as thousands of similar electronic trading
systems, cell phones, radio programs and local scrip "currencies" used
to match needs and resources and clear local markets starved of credit.
Wall Street’s single-minded focus on money led to its demise. Money was
equated with wealth and ignored all the other forms of wealth, from
human skills, networks and ingenuity to the productive systems of nature
in which all economies are embedded. Money, like gold, will remain a
useful store of value and medium of exchange, but now as part of a new
broader, more inclusive regime dominated by pure, information-based
markets.
The G-20's next meeting in September 2009 must address the
need for a new global reserve currency. China is assuming responsible
leadership on this issue as with its October 2008, convening 40 leaders
for the 7th Asian-European Meeting in Beijing, included representatives
of the 27 European countries, 10 ASEAN countries, the European
Commission, China, Japan, South Korea, India, Pakistan and Mongolia.
China's foreign ministry spokesman Qin Gong said "China maintains that
the international community should strengthen cooperation and jointly
handle the current financial crisis on the basis of equal consultation."
Our club can support a Chinese leader to become president of the IMF, an
Indian to head the World Bank and to elect Brazil as a permanent member
of the UN Security Council.
Clearly, the world's money systems have
been corrupted, and the basic value of trust which underlies all markets
has been shattered. We are now learning that not all our transactions
can be trusted to money systems and that in today's Information Age
there are the many new, pure, information-based trading systems
mentioned earlier, including international barter, "countertrade"
between governments, trading between global companies of everything from
media and telephony to commodities. Information and money are equivalent
mediums of exchange and equally valuable. Many investors are now
bypassing Wall Street and big money centers in favor of private equity
on trusted electronic liquidity and trading networks. Such insights into
the use of information and trading networks, including local currencies,
barter and people-to-people lending are part of the emerging
information-rich Solar Age economies now superseding the earlier
fossil-fueled Industrial Age.12
Some additional reforms the Club of
Rome might wish to support, as agenda items for the next G-20 meeting in
New York in September 2009:
* Imposing globally-harmonized currency
exchange taxes is an obvious step. Promoted, as mentioned, for decades
by economists from James Tobin, Bank of Sweden's Nobel Memorial
prizewinner, to former US Treasury Secretary Larry Summers, this below
1% tax on the $3 trillion daily currency trading would reduce some of
its 90% speculative activity. Recent levels of turbulence in currency
markets are not sustainable, and Ben Bernanke's selling US dollars to
buy other currencies was unprecedented. Only global regulation of
currency markets, by the FXTRS or similar systems, can address the
problem of weaker currencies leading countries to default.
* To
reduce the over $1 trillion annually countries spend on military
hardware, the summiteers can agree on the proposed United Nations
Security Insurance Agency (UNSIA). Militarism is ever-less useful in
resolving today's conflicts in Iraq, Afghanistan and other guerilla
insurgencies. This UNSIA proposal, backed by four Nobel laureates, would
allow countries which wished to follow Costa Rica's lead in 1947 and
abolish their armed forces. Instead, countries could buy the insurance
of a peacekeeping force from the UN Security Council (expanded and
veto-less). Their premiums would be determined by insurance industry
risk assessors contracted to see that the country had no WMD or secret
weapons and did not teach militarism and xenophobia. Countries, say
those in Central America, that decided to all buy UNSIA insurance would
all get lower premiums. The premiums would fund a standing, properly
trained UN peace-keeping force and complimentary contingents of NGO
peace-making conflict-resolution groups. The UNSIA proposal is taught in
many university programs and was debated in the UN Security Council in
1996 (see UNSIA). This and other proposals,
including the FXTRS, are also described in The United Nations Policy and
Financing Alternatives, (1995).13
These two global reforms could be
introduced at the New York summit, debated in the UN General Assembly
and ratified by member countries. Many other reforms discussed earlier
should be on the agenda::
-
Reform of ill-designed monetary systems
based on debt (see
www.ethicalmarkets.tv "Money as Debt" and the
American Monetary Reform Act of 2008 at
www.monetary.org); in the UK,
monetary reforms proposed by banking expert James Robertson at
www.jamesrobertson.com and those of the New Economics Foundation at
www.neweconomics.org). This includes raising capital reserve
requirements for banks and reducing leverage used by all financial
players.
-
Criminalizing of tax arbitrage and avoidance in tax havens,
including those non-cooperative countries and territories black-listed
by the US Treasury and many central banks (see the international
Financial Action Task Force
NCCT Initiative at
www.fatf-gafi.org). This
list must now include the USA and the UK.
-
Implement the regulating
and requiring full disclosure of hedge funds, private equity funds,
sovereign wealth funds, credit derivatives and "dark pools" of capital.
Harmonizing market rules to prevent arbitrage between major securities
markets. Changing incentives toward long-term investment goals and
limiting compensation by giving shareholders a voice on this and other
social, environmental and governance issues now clearly material to
stock valuations. Rating agencies should only accept fees from
investors, not issuers of securities.
-
Repealing Basel II rules which
allowed banks to assess their own risks, the failure of which helped
bring on the crisis. Raising capital adequacy and reserve ratios and
reducing margins on all transactions. Leveraging standards on banks
operating internationally are also needed. Many of these proposals are
by law professor Daniel K. Tarullo, an advisor to President Obama, in
Banking on Basel.14 Raising margin requirements and increasing Basel II
capital reserve ratios also reduce speculation in all markets and
futures and derivatives exchanges.
All these regulations, as we
have learned, are to re-balance the roles of private and public sectors
now that governments have been forced to intervene using taxpayers
money. The new rules must be by international agreement lest market
players skip from state to state "arbitraging" different jurisdictions
and tax regimes. Even the World Economic Forum in Davos in January found
a consensus of both government and business leaders for such
global-level agreements and standards. The UN Principles of Responsible
Investment, the Global Reporting Initiative, the Social Investment
Forum, ASRIA and many other groups are calling for similar reforms. At
last, this global financial crisis brings the opportunities discussed
for decades to reform today's global casino and restore finance to its
vital but limited role in facilitating real production and innovation in
the world's real economies. The Club of Rome has led the way toward
reforms for 40 years. Today, it's insights and proposals are needed more
than ever.
Thank you.
