Public
choice theory demonstrates why looking to government
to fix things can often lead to more harm than good,
as one of its leading architects and Nobel
laureate James M. Buchanan explains
Public choice should be understood as a research programme rather than a discipline
or even a sub-discipline of economics. Its origins date to the mid-20th century,
and viewed retrospectively, the theoretical 'gap' in political economy that
it emerged to fill seems so large that its development seems to have been inevitable.
Nations
emerging from World War II, including the Western democracies,
were allocating between one-third and one-half of their
total product through political
institutions
rather than through markets. Economists, however, were devoting their efforts
almost exclusively to understanding and explaining the market sector. My
own modest first entry into the subject matter, in 1949,
was little more than a
call for those economists who examined taxes and spending to pay some attention
to
empirical reality, and thus to politics.
Initially,
the work of economists in this area raised serious doubts
about the political
process. Working simultaneously, but independently, Kenneth
Arrow and
Duncan Black proved that democracy, interpreted as majority rule, could
not work to promote any general or public interest. The
now-famous 'impossibility
theorem',
as published in Arrow's book Social Choice and Individual Values (1951),
stimulated an extended discussion. What Arrow and Black had in fact done
was to discover
or rediscover the phenomenon of 'majority cycles', whereby election results
rotate in continuous cycles with no equilibrium or stopping
point. The suggestion of this analysis was that majoritarian
democracy is inherently
unstable.
I entered
this discussion with a generalised critique of the analysis
generated by the Arrow-Black approach. Aren't
'majority cycles' the most desirable
outcome of a democratic process? After all, any attainment of political
equilibrium via
majority rule would amount to the permanent imposition of the majority's
will on the outvoted minority. Would not a guaranteed rotation of outcomes
be preferable,
enabling the members of the minority in one round of voting to come back
in subsequent rounds and ascend to majority membership? My concern, then
and later, was the
prevention of discrimination against minorities rather than stability
of political outcomes. The question, from an economist's
perspective, was
how to obtain a
combination of efficiency and justice under majority rule.
Wicksell's insight
The great Swedish economist Knut Wicksell was the most important of all
precursory figures in public choice. In his dissertation, published in
1896, he was
concerned about both the injustice and the inefficiency resulting from
unfettered majority
rule in parliamentary assemblies. Majority rule seemed quite likely to
impose net costs or damages on large segments of the citizen or taxpayer
group.
Why should members of such minorities, facing discrimination, lend their
support
to democratic political structures? Unless all groups can benefit from
the ultimate exchange with government, how can overall stability be maintained?
These
considerations led Wicksell to question the efficacy of majority rule
itself. His solution to the problem was to propose that majority
rule be
modified in
the direction of unanimity. If the agreement of all persons in the
voting group is required to implement collective action,
it would guarantee
that all persons
secure net gains and, further, that the approved actions would yield
benefits in excess of costs. Of course, Wicksell recognised that, if
applied in
a literal voting setting, a requirement of unanimity would produce
stalemate. To recognise
this, however, does not diminish the value of the unanimity rule as
a benchmark for comparative evaluation. In suggestions
for practical constitutional
reforms,
Wicksell supported changes in voting rules from simple to qualified
or super majorities, for example, a requirement of five-sixths
approval
for
collective
proposals.
In their
analyses, Black and Arrow had assumed, more or less implicitly,
that the choices to be voted on exist prior
to, and outside
of, the decision-making process itself. Wicksell understood the error
in this
assumption, although
he did not recognise the importance of this insight.
Neither did Gordon Tullock, who wrote a seminal paper in
1959 using the example
of farmer voters, each
of whom wants to have his local road repaired with costs
borne by the whole community. Tullock showed that majority rule allows
for coalitions
of such
farmers to generate election results that impose unjust
costs on the whole community while producing inefficiently large
outlays on
local roads.
If majority
rule produces unjust and inefficient outcomes, and if political
stability is secured only by discrimination
against minorities, how can democracy, as the organising principle
for political
structure, possibly
claim normative legitimacy? Wicksell's criterion for
achieving justice and efficiency in collective action-the shift
from majority rule
toward unanimity-seems
institutionally impractical. But without some such
reform, how could taxpayers be assured that their participation
in the democracy
would
yield net benefits?
Constitutional economics
In implicit response to these questions, Tullock and
I commenced to work on what was to become The Calculus
of
Consent, published
in 1962. The central contribution
of this book was to identify a two-level structure of collective
decision-making. We distinguished between 'ordinary
politics', consisting of decisions
made in legislative assemblies, and 'constitutional
politics', consisting
of decisions
made about the rules for ordinary politics.
We were
not, of course, inventing this distinction. Both in legal
theory and in practice,
constitutional law had long been distinguished
from
statute law.
What we did was to bring this distinction into economic analysis.
Doing so allowed us to answer the questions posed previously:
From the perspective
of both justice
and efficiency, majority rule may safely be allowed to operate
in the realm of ordinary politics provided that there is generalised
consensus
on the
constitution,
or on the rules that define and limit what can be done through
ordinary
politics.
It is in arriving at this constitutional framework where Wicksell's
idea of requiring unanimity-or at least super majorities-may
be practically incorporated.
In a
sense, the analysis in our book could have been interpreted
as a formalisation
of the structure that James Madison and his
colleagues had in mind when
they constructed the American Constitution. At the least, it
offered a substantive
criticism of the then-dominant elevation of unfettered majority
rule to sacrosanct status in political science.
Our
book was widely well received, which prompted Tullock and
me, who
were then at the University of Virginia, to initiate
and organise
a
small research
conference
in April 1963. We brought together economists, political
scientists, sociologists and scholars from other disciplines,
all of whom
were engaged in research
outside the boundaries of their disciplines. The discussion
was sufficiently stimulating
to motivate the formation of an organisation which we first
called the Committee on Non-Market Decision-Making, and to
initiate
plans for a
journal to be
called Papers on Non-Market Decision-Making.
We
were unhappy with these awkward labels, and after several
meetings there
emerged the new name 'public choice', both
for the organisation
and the
journal. In this
way the Public Choice Society and the journal Public Choice
came into being. Both have proved to be quite successful
as institutional
embodiments
of
the research programme, and sister organisations and journals
have since been
set up in Europe
and Asia.
Many
sub-programmes have emerged from the umbrella of public
choice. One in particular deserves mention-'rent
seeking',
a sub-programme
initiated in a paper by Tullock
in 1967, and christened with this title by Anne Krueger
in 1974. Its central
idea emerges from the natural mindset of the economist,
whose understanding and explanation of human interaction
depends
critically on predictable
responses to measurable incentives. In essence, it extends
the idea of the profit motive
from the economic sphere to the sphere of collective
action. It presupposes that
if there is value to be gained through politics, persons
will invest resources in efforts to capture this value.
It also
demonstrates how this investment
is wasteful in an aggregate-value sense.
Tullock's
early treatment of rent seeking was concentrated on monopoly,
tariffs and theft, but the list could be
almost indefinitely
expanded.
If the government
is empowered to grant monopoly rights or tariff protection
to one group, at the expense of the general public
or
of designated losers,
it follows
that potential
beneficiaries will compete for the prize. And since
only one group can be rewarded, the resources invested
by
other groups-which
could
have
been used
to produce
valued goods and services-are wasted. Given this basic
insight, much of modern politics can be understood
as rent-seeking activity. Pork-barrel
politics
is only the most obvious example. Much of the growth
of the
bureaucratic
or regulatory
sector of government can best be explained in terms
of the competition between political agents for constituency
support
through the
use of promises
of
discriminatory transfers of wealth.
As noted,
the primary contribution of The Calculus of Consent was
to distinguish
two levels of collective
action,
ordinary
or day-to-day
politics and constitutional
politics. Indeed, the subtitle of that book was 'Logical
Foundations of Constitutional Democracy'. Clearly,
political action takes
place at two
distinct levels, one within the existing set of rules
or constitution, the other establishing the rules
or constitution
that impose
limits on subsequent
actions.
Only recently have economists broken away from the
presumption that constraints on choices are always
imposed from the
outside. Recent
research has involved
the choice of constraints, even on the behavior of
persons in non-collective settings, for instance,
with regard
to drug or
gambling addiction.
But even beyond that, what I have called the 'constitutional
way of thinking'
shifts
attention
to the framework rules of political order-the rules
that secure consensus among members of the body politic.
It
is at this
level that individuals
calculate their
terms of exchange with the state or with political
authority. They may well calculate that they are
better off for
their membership in the constitutional
order, even
while assessing the impact of ordinary political
actions to be contrary to
their interests.
A somewhat loose way of putting this is to say that
in a constitutional democracy, persons owe loyalty
to the
constitution
rather than
to the government. I
have long argued that on precisely this point, American
public attitudes are quite
different from those in Europe.
Objections
to public choice
There is a familiar criticism of public choice theory to the effect that it is
ideologically biased. In comparing and analysing alternative sets of constitutional
rules, both those in existence and those that might be introduced prospectively,
how does public choice theory, as such, remain neutral in the scientific sense?
Here
it is necessary to appreciate the prevailing mindset of
social scientists and philosophers at the midpoint
of the 20th century when public choice arose. The socialist
ideology
was pervasive, and was supported
by the
allegedly neutral
research programme
called 'theoretical welfare economics', which
concentrated on identifying the failures of observed markets
to meet idealised standards. In
sum, this branch
of inquiry offered theories of market failure.
But failure in
comparison with what? The implicit presumption
was always that politicised
corrections for market
failures would work perfectly. In other words,
market failures were set against an idealised politics.
Public
choice then came along and provided analyses
of the behavior of persons acting politically,
whether voters,
politicians
or
bureaucrats. These analyses
exposed the essentially false comparisons that
were then informing so
much of both scientific and public opinion.
In a very real sense, public choice
became
a set of theories of governmental failures,
as an offset to the theories of market failures
that had
previously
emerged from
theoretical welfare
economics. Or,
as I put it in the title of a lecture in Vienna
in 1978, public
choice may be summarised by the three-word
description, 'politics without
romance'.
The
public choice research programme is better seen as a correction
of the scientific record
than as
the introduction
of an anti-governmental
ideology.
Regardless
of any ideological bias, exposure to public
choice analysis necessarily brings a more
critical attitude
toward politicised
nostrums to
alleged socioeconomic
problems. Public choice almost literally
forces the critic to be pragmatic in comparing alternative
constitutional
arrangements,
disallowing any
presumption that bureaucratic corrections
for
market failures will
accomplish
the desired
objectives.
A more
provocative criticism of public choice centres on the claim
that it is immoral.
The source of
this charge lies in
the application
to politics
of the
assumption that individuals in the marketplace
behave in
a self-interested way. More specifically,
economic models of
behaviour include
net wealth, an externally
measurable variable, as an important 'good'
that individuals seek to maximise. The
moral condemnation
of public
choice is centred
on the
presumed transference
of this element of economic theory to political
analysis. Critics argue that people acting
politically -for example, as voters or as legislators-do
not behave as
they do in
markets.
Individuals are
differently motivated
when they are choosing 'for the public'
rather than for themselves in private choice
capacities.
Or so
the criticism
runs.
At base,
this criticism stems from a misunderstanding that may have
been fostered by the failure
of economists to
acknowledge the limits
of their
efforts. The
economic model of behaviour, even if
restricted to market activity, should never be taken
to provide the be-all
and end-all of
scientific
explanation.
Persons
act from many motives, and the economic
model concentrates attention only on
one of the
many possible forces
behind actions. Economists
do, of course,
presume
that the 'goods' they employ in their
models for predicting behaviour are relatively
important. And
in fact, the
hypothesis that promised
shifts in net wealth modify
political behaviour in predictable ways
has not been readily falsifiable empirically.
Public
choice, as an inclusive research programme, incorporates
the presumption
that persons
do not readily become economic
eunuchs as
they shift from
market to political participation.
Those who respond predictably to ordinary incentives
in the marketplace do not fail to respond
at
all when they act as citizens. The
public choice theorist
should,
of
course, acknowledge
that the
strength and predictive
power of the strict economic model
of behaviour is somewhat mitigated as the
shift is made
from private
market to
collective choice.
Persons
in
political roles may, indeed, act to
a degree in terms of what they consider
to be the
general
interest. Such acknowledgment does
not, however, in any way imply that the basic
explanatory
model loses
all
of its predictive
potential, or that ordinary
incentives
no longer matter.
Impact
of public choice
Public choice theory has developed
and matured over the course of a
full half-century.
It
is useful to
assess
the impact
and effects of
this programme,
both on thinking
in the scientific community and in
the formation of public attitudes.
By simple
comparison
with the climate
of opinion
in 1950, both
the
punditry and the public
are more critical of politics and
politicians, more cynical about the motivations
of political action, and less naive
in thinking that political nostrums
offer
easy solutions
to social
problems. And this
shift in attitudes
extends well
beyond the loss of belief in the
efficacy of socialism, a loss of belief grounded
both in historical regime failures
and in the
collapse
of intellectually idealised structures.
As
I noted earlier, when we look back
at the scientific and public
climates
of discussion
50 years ago,
the prevailing mindset was
socialist in its
underlying presupposition that
government offered
the solution to social problems.
But there
was a confusing amalgam of Marxism
and ideal political theory
involved: Governments, as observed,
were modelled and condemned by
Marxists as furthering class
interests, but governments which
might be installed 'after the revolution',
so to speak,
would become both omniscient and
benevolent.
In some
of their implicit modelling of political behavior aimed
at
furthering special group
or class interests,
the Marxists
seemed to be closet associates
of public choice, even as they
rejected methodological individualism.
But
how was the basic Marxist
critique of politics, as observed,
to be transformed
into
the idealised politics of the
benevolent and omniscient superstate? This
question was simply
left glaringly
unanswered. And the
debates of the
1930s were considered
by confused economists of the
time to
have been won by the socialists
rather than
by their opponents,
Ludwig von Mises
and Friedrich
Hayek.
Both sides,
to an extent, neglected the relevance
of incentives in
motivating human action, including
political action.
The
structure of ideas that was adduced in
support of the emerging
Leviathan
welfare state was logically
flawed
and
could have
been maintained only
through long-continued illusion.
But, interestingly, the failure,
in whole
or in
part, of the socialist structure
of ideas did not come from within the academy. Mises and
Hayek were
not successful in their early efforts,
and classical liberalism
seemed
to be at its nadir at mid-century.
Failure came, not from a collapse of an intellectually
defunct
structure
of ideas,
but
from the
cumulative record
of non-performance
in the implementation of extended
collectivist schemes-non-performance measured
against promised claims, something
that could be observed
directly. In other words, governments
everywhere overreached. They tried
to do more
than the
institutional framework would
support. This record of failure, both in the socialist
and
welfare states, came to be recognised widely,
commencing in the 1960s and accelerating in the
1970s.
Where
is the influence of public choice in this history? I do
not claim that it dislodged the prevailing
socialist mindset in the academies, and that this
intellectual shift then exerted feedback on political reality. What I do claim
is that public choice exerted major influence in providing a coherent understanding
and interpretation of what could be everywhere observed. The public directly
sensed that collectivistic schemes were failing, that politicisation did not
offer the promised correctives for any and all social ills, that governmental
intrusions often made things worse rather than better.
How could these direct observations
be fitted into
a satisfactory
understanding?
Public
choice came along and offered a foundation
for such
an understanding.
Armed
with nothing
more than
the rudimentary
insights
from public
choice, persons could understand
why, once established,
bureaucracies tend
to grow apparently
without limit and without
connection to initially
promised functions.
They could
understand
why pork-barrel politics
dominated the
attention of legislators;
why
there seems to be a direct
relationship between the
overall size of government
and the investment
in
efforts to secure
special
concessions from government
(rent seeking); why the
tax system is described by the
increasing
number of special
credits, exemptions, and
loopholes;
why
balanced budgets are so
hard to secure; and why strategically
placed
industries secure tariff
protection.
A version
of the old fable about the
king's nakedness
may be helpful
here.
Public choice
is like the
small boy who
said
that the king
really has no
clothes. Once
he said this, everyone
recognised that the king's
nakedness
had been recognised,
but
that no-one
had really called
attention to this fact.
Let
us be careful not to claim too much, however.
Public choice
did
not emerge
from some profoundly
new insight,
some new discovery,
some social
science
miracle. Public choice,
in its basic insights
into
the
workings
of
politics, incorporates
an understanding of
human nature that differs little,
if at
all, from that
of James Madison
and his colleagues
at
the time
of
the American
Founding.
The essential
wisdom of the 18th
century, of Adam Smith and classical
political
economy
and of
the American
Founders,
was lost through two
centuries of intellectual
folly.
Public choice does
little more than incorporate
a rediscovery of this
wisdom and its
implications into
economic analyses
of modern
politics.
