This is a position paper by Michael Froomkin for the Panel on
‘Governmental and Social Implications of Digital Money' at Computers,
Freedom & Privacy Conference (CFP'97)
Address: Burlingame, California, USA
Time: Wed. March 12, 1997, at 2pm.
Panelists: Roger Clarke, David Chaum, Michael Froomkin,
and Tim May.
The Unintended
Consequences of E-Cash
Electronic cash, broadly defined, includes both smart-card based
tokens of value and digital coins or other digital tokens of value
(e.g. "digital checks"). If these distinctions are not meaningful to
you, please see Digital
Cash: A Technical Menu.
For the foreseeable future I predict these new payment media will
have major economic effects only in the part of the economy that uses
small and micro-transactions. Unless legal rules change significantly,
consumers who live in jurisdictions that provide legal protections for
debit or credit cards transactions will tend to use them for larger
payments. After all, why use e- cash when you can use a credit card and
cancel the payment if the seller fails to deliver what was promised?
Thus, e-cash will have relatively modest overall effects on commerce,
the money supply, and the economy. And e-cash will have equally modest
effects on taxes and social mores.
The (Mostly) Bad News
I predict that most of the social effects of e-cash will be
negative, in part due to the (over) reaction from regulatory
authorities, in part due to the ways in which corporations will be able
to amass more data on consumers. Government action will (largely
unintentionally) exacerbate the negative effects of e-cash on
privacy:
Profiling. The increasing use of e-cash for small and
especially "micro" transactions such as viewing a web page will vastly
increase businesses' (and, arguably, governments') ability to put
together detailed profiles of consumers/ citizens. If the World Wide Web
or its successors become fee- based systems in which readers are charged
for access, consumers who use traceable digital cash will find that
their reading habits as well as transactions become valuable, tradeable
data. This will lessen their privacy and could have a chilling effect on
readers and, possibly, on authors also. If the Web succeeds in
supplanting other media, the social consequences could be very great.
The Internet or related networks may become the foundation of the
opposite of anarchy: life in a transparent data ocean, a life in which
data recording everyone's movements, tastes, purchases, medical history,
reading habits, and contacts with officialdom are commodified and
available to some, and perhaps even to all.
Limited Regulatory Arbitrage. This is
the only major social effect I foresee which is not wholly negative.
E-cash will facilitate trans-border transactions in which no physical
goods are exchanged. Legal transactions will most often occur in other
payment media, notably credit and debit cards, because consumers will
have greater legal protection if something goes awry with the
transaction. Today's trans-border gambling and trans-border sale of
pornography will in time pave the way for trans-border securities
trading and off-shore brokerages, some of which will violate the laws of
the customer's home state. However, unless large amounts of untraceable
anonymous currency are in wide circulation, and these funds are widely
accepted for physical purchases as well as electronic commerce, the
owners of electronic cash will need a means of transferring funds from
electronic cash to ordinary cash. In most cases, the owners of
significant sums of electronic cash will also want to invest their
funds. In either case they will require the services of a financial
service provider, such as a bank. Thus, at least in the medium term,
governments may be able to control anonymous commerce by concentrating
on financial service providers. Financial service providers are already
highly regulated, and present a relatively easy target for governments
seeking to prevent fully anonymous fund transfers. Regulators may also
benefit from the reluctance of consumers to bank abroad, even when
offered accounts denominated in their home currency. If, however,
consumers become more willing to bank abroad, the ability of governments
to control anonymous transactions will be reduced further, unless all or
almost all governments are able to agree on common rules.
Law Enforcement Reaction. Law enforcement agencies' fear
that anonymous e-cash can easily be used for money laundering will lead
to vigorous government action to secure some combination of the
following:
- Legal prohibitions on the issuance of anonymous and semi-anonymous
e-cash, thus exacerbating the profiling phenomenon described above;
- Legal prohibitions on the use of anonymous or semi- anonymous
e-cash;
- A requirement that some form of "identity escrow," i.e. a
subpoenable record of the user's identity, be built into the
e-cash;
- An attempt by governments to influence standards creation to
discriminate against e-cash systems that allow either peer-to-peer
transfers or even payor anonymity;
- In the somewhat likely event that governments fail to achieve any of
the above objectives, I expect increasingly stringent rules, agreed at
the international level, requiring that all movements of liquid assets,
including ever-smaller sums, be registered with financial authorities.
The existence of violations of these rules will then become a basis for
further erosion of civil liberties, as the "war on money laundering"
becomes an increasingly prominent component of the "war on drugs". Both
financial privacy and privacy generally will decrease.
Harms to Litigation Concerning the Right to Anonymous
Speech. Because of the technical reality that it is impossible to
distinguish an anonymous electronic payment from an anonymous private or
political message, the legality of the regulation of e-cash will become
the legal terrain over which most legal battles concerning
constitutional or statutory rights to anonymous speech will be fought.
While not necessarily fatal to the cause of anonymous speech in the
U.S., the identification of anonymous speech with money laundering will
put anonymous remailers and other facilitators of anonymous speech into
a defensive litigation posture which will tend to harm their prospects
in the U.S. courts.
What Won't Happen
I also predict that the certain social phenomena that one sometimes
sees suggested as likely consequences of the widespread adoption of
e-cash will not come to pass in the near future:
- E-cash itself will not cause major changes in the nature of
retailing. This will happen, but as result of web commerce itself, not
due to the existence of any particular payment mechanism.
- E-cash itself, even anonymous e-cash, will not cause major changes
in the tax system or enable large-scale tax avoidance. Most production
and even more consumption involves transactions that are easily
monitored for tax compliance. Income tax non-compliance requires payor
as well as payee to participate in avoidance. Widespread deduction and
reporting of tax at source makes this unlikely. My income, for example,
comes from a salary paid by an institution that has no incentive to make
it easy for me to engage in tax avoidance. (The U.S. economy is said to
be shifting towards smaller sized businesses. As owner-operated
businesses and independent contractors increase, the potential for tax
fraud grows too. This, however, is as true whether payments are
electronic or not.) Some knowledge workers may be able to demand
that payment be routed to accounts held at untaxed off-shore addresses,
thus causing an effect at the margin, but I think such schemes will
remain only marginal for the foreseeable future. Furthermore, any
transaction that encounters the banking system – for example, deposits
placed on short-term interest – will be easily traceable for tax
purposes so long as the bank is located in a jurisdiction that enlists
banks as enforcers of its, or its treaty-partners', tax rules. Few
nations offer strong banking secrecy today, and the international effort
to curb money laundering has reduced their number; some nations that
continue to offer strong banking secrecy may lack the political
stability necessary to lure risk-averse investors. Conceivably, the tax
system might begin to feel the effects if a reputable bank in a country
with a stable currency and a trustworthy regulatory system were to offer
anonymous electronic cash accounts on terms attractive to ordinary
consumers. In that event, other countries would still be able to
mitigate the effects by switching to a Value Added Tax (VAT) system,
since tax cheating under VAT would require the participation of more
people in the chain of production.
- Most tangible goods regulation known in the U.S. as the "police
power" will remain unaffected by the Internet and its cousins. Food and
drug regulation does not change because research chemists have new ways
of communicating. Traffic laws, pension laws, tort law, indeed vast
tracts of the legal and social landscape will no doubt change in the
future – but not because of e-cash.
The Long-Term
If the internet generally, perhaps aided by the prevalence of e-cash,
were to change migration patterns, things would begin to look very
different. Workplace safety rules do not need to change to lose their
effectiveness if the workplace moves. It may be that certain types of
knowledge workers based in low-wage areas will be able to increase the
market for their services. Mathematicians and programmers have already
begun to exploit this opportunity; perhaps editors and artists will be
next. As the Internet becomes the leading means to rapidly disseminate
scientific, technical and even social information, persons in less
developed countries who find themselves isolated in provincial areas, or
are concerned about keeping abreast of developments in their field may
conclude that they no longer have to move to more developed countries
and regions to do cutting-edge work, or to participate in scholarly
exchanges. The increased ability of some persons in traditionally
low-wage areas to sell their services on the world market and
participate in global dialogues may help stem the so-called "brain
drain". Indeed, it may increase the "reverse brain drain" as some
expatriates return to their country of origin, perhaps even joined by a
new wave of expatriate knowledge workers seeking a lower cost of living.
Whether or not this happens in the long term, I am confident it will not
happen in any large sense in the short or medium term.
