6. SOCIAL MARKET FOUNDATION
The triumph of the market system over the planned economy was probably the defining
economic event of our lifetime, its symbol the collapse of the Berlin Wall in 1989. In the
advanced economies of the West, increased government intervention, more or less unchecked
through the twentieth century, was halted in 1980 by the ideologically conservative
governments of Reagan and Thatcher. Their policy innovations were widely if often reluctantly
imitated elsewhere. In Asia, China and India followed some of their smaller neighbours into
the market economy and the global trading system.
These developments provoked the hubris famously framed as The End of History by Francis
Fukuyama. Fukuyama argued that a combination of liberal democracy and lightly regulated
capitalism was now an inevitable form of political and economic organisation. If one country
was the standard bearer for that new vision of the twenty-first century, it was the United States:
if one industry was the standard bearer for that new view of business, it was the financial
services industry.
Today, Fukuyama’s assertion lacks conviction. If there were defining events in that revisionism,
analogous to the breaching of the Berlin Wall, this would be – for politics – the collapse of the
Twin Towers and its bungled consequences, and for economics the bankruptcy of Lehman
seven years later. There is, evidently, no end of history – as, indeed, Fukuyama today readily
It is time for a more nuanced view of the nature of markets and the merits of the market
economy. The critique of the market economy today is, as it has been since the end of
socialism, largely incoherent – an incoherence nicely captured in the demonstrator’s slogan
‘capitalism should be replaced by something nicer’.
But the defence of the market economy is often little more coherent. Supporters often do no
more than point at the wealth of countries that have adopted the market economy – and to
their own personal wealth. That isn’t necessarily a bad argument. But it looks tarnished today.
When those people who are the largest beneficiaries in terms of their own personal wealth
have done substantial damage to the wealth of other people, that argument becomes more
difficult to sustain.
I am going to argue that there are three elements to the triumph of the market economy. The
first I will describe under the heading of ‘prices as signals’, the price mechanism is generally a
better guide to resource allocation than central planning. The second element is ‘markets as a
process of discovery’ – the chaotic process of experimentation through which a market
6
7. THE MARKET ECONOMY
economy adapts to change. The third heading is ‘diffusion of political and economic power’.
The economic point here is that prosperity and growth require that entrepreneurial energy
should be focussed on the creation of wealth, rather than the appropriation of the wealth of
other people.
In what we teach, in what we say, in our economic research and most importantly in the
policies we adopt – we put too much emphasis on the first of these elements – prices as
signals to guide resource allocation – at the expense of the, possibly more important, second
and third elements – markets as process of discovery, markets as mechanism for the diffusion
of political and economic power.
The result is that both supporters and critics of the market economy have often confused
policies that are pro-business with policies that are pro-market. That confusion has both
undermined the social and political legitimacy of the market economy, and led to serious
policy errors that follow from a mistaken, or at least incomplete, understanding of how a
market economy works.
DISCIPLINED PLURALISM
One central theme runs through all three strands of argument, the theme of disciplined
pluralism. When prices act as signals decentralised enterprises and decentralised information
are brought together to create a coherent result. Markets as a process of discovery are based
on freedom to experiment, combined with discipline: unsuccessful experiments
acknowledged and terminated. The use of markets as a means of decentralising power
determines the shape of the areas where politics and economics meet.
If the essence of markets is their pluralist character, then there is an inevitable association
between the successful market economy and other components of an open society – freedom
of expression, and democratic institutions. While it is evident that authoritarian regimes have
operated market economies, at least for a bit, the combination is probably not sustainable in
the long run. There is an important corollary: political freedom is jeopardised by excessive
concentrations of economic power. Even if Fukuyama was wrong in his assertion of
inevitability, the identification of an elective affinity between liberal democracy and lightly
regulated capitalism was entirely appropriate.

‘THE MODEL’ AS ECONOMIC THEORY
The model of ‘prices as signals’ describes how self-interested agents – individuals or firms –
might, through independent decisions, make consistent and efficient choices about how to
organise production and distribution and the allocation of capital, labour and other resources.
In a loose formulation, this idea has been around since the beginnings of economics. Many
people interpret in this way Adam Smith’s famous remark about ‘the invisible hand’, and his
observation that it was not the benevolence of the baker, but his self-love, that furnished our
table. In an astonishing demonstration of the power of spontaneous order, decentralised
markets manage the process of coordinating complex production systems better than
centralised direction.
Although it appears to be an empirical fact that markets achieve such coordination,
economists did not offer a comprehensive explanation of why until the 1950s. The
explanation they gave then proved both that a competitive equilibrium might exist, and that, if
it did exist, it could be efficient. That general equilibrium model (concisely ‘the model’)
proved largely influential, both in shaping the research agenda of the economic profession
and in providing an intellectual basis for economic policy among people who may know
nothing of the underlying arguments.
The implication is that profitable transactions are socially beneficial: indeed that their social
benefit is demonstrated by their profitability. A corollary is of the ‘market failure doctrine’,
which is central today in economic policy in Britain and Brussels: intervention in markets is
justifiable only in the light of a narrowly defined list of market failures, which is generated by
deviations between the world and the assumptions of the model.
The model also provides a rationale for a certain kind of market fundamentalism. Not only is
interference with market forces usually inappropriate, but market outcomes are efficient, even
morally justifiable, simply by virtue of being market outcomes. Not only are markets good, but
more markets are better than fewer markets. The emergence of new markets for financial
products, for example, is presumptively beneficial.
Among economists, the popularity of this approach is in large part the result of physics envy:
the general equilibrium model provides a universal explanation of economic affairs which
resembles in many ways the equilibrium models that have proved so powerful in the natural
sciences. Rigour has become the measure of the quality of a theoretical economic argument,
where rigour means the logical consistency which readily finds mathematical expression.

9. THE MARKET ECONOMY
THE OMISSION OF SOCIETY
Among practical people, the simple message that government should go away and leave
business alone has wide appeal to business: and the simple message that greed can serve a
constructive social role also has wide appeal to greedy people. The claim that profitability
demonstrates, is even the measure of, public benefit relieves people of any worries they might
have harboured about the utility of their profitable activities. These worries are not common,
but one does occasionally encounter them.
These messages, however, angrily resisted by the broader intellectual community, which finds
both the assumed motivation and the conclusions unappealing. These messages are also
resistible to the population at large, which does not run business, benefits only indirectly from
the activities of business, and is not necessarily enamoured of greed. The political world today
is one in which both parties and voters acknowledge the empirical success of the market, but
dislike almost every aspect of it. ‘The market’ and ‘market forces’ are the source of our
prosperity, but are also terms of abuse. We have succeeded in providing a description of how
markets work that is at once repulsive and substantially false.
The model probably contributes something to our understanding of how markets work. But
that contribution is largely misunderstood and grossly over-emphasised. One problem is that
there is no real acknowledgement of uncertainty in the model, or, to be more precise,
uncertainty is acknowledged only in essentially formal ways. This omission is of fundamental
importance when the model is used to describe financial markets, in which trading in risk is the
essence of the transaction. In these markets, the means of incorporating uncertainty into the
model requires, in effect, that there is some true underlying value of an asset, which is
independent of beliefs about that value, and that market transactions involve a process of
convergence towards the true value. Experience has demonstrated clearly that this claim is a
hopelessly inadequate account of market behaviour.
A larger problem is that the model fails to recognise the extent to which a functioning market
economy is embedded in the society of which it forms part. Property rights are not a fact, but
a social construction: and there are many alternative ways in which these rights could be
constructed. In a modern economy characterised by complex products, sellers generally know
more about what they are selling than buyers about what they are buying. Trust relationships
and supplier reputation are the market’s mechanisms for handling this problem.
These are not theoretical quibbles: they are problems at the centre of recent events. There
were always two broad accounts of the reasons for the explosion of trade in complex
structured products in the financial sector over the last decade. In one, these developments
9
10. SOCIAL MARKET FOUNDATION
represented a more sophisticated form of risk sharing and risk transfer, an exemplification of
the benefit of the creation of new markets. In another, the trade was mainly driven by
information asymmetry: the products were bought by people who overestimated their value.
The consequences of these two explanations are very different. When complex products bring
about more efficient risk allocation, the private profitability is mirrored by public benefits in the
form of lower costs of risk. When such products are bought by people who do not understand
them, private profitability overall is illusory and disappears when asset prices ultimately revert
to the underlying value of the asset.
In retrospect, it is evident that this latter explanation is closer to the truth. Trade was driven by
differences of information and interpretation and the profits from it evaporated when these
errors were revealed. That is why Adair Turner is right when he invites us to query the social
value of current trading values, and when he suggests that its extent goes far beyond what is
needed to serve its economic function.
MARKETS EXPLORE, THEY DON’T PREDICT
There is a good deal more to the power of markets than the description of prices as signals
contains. The world is uncertain: not just risky, but uncertain, in the sense used by Keynes and
Knight. Not only do we not know which future outcomes will happen: we are unable to
specify at all fully what these possible outcomes will be. If we could predict or anticipate the
invention of the wheel, we would have already invented it. Market economies do not predict
the future, they explore it. That is a fundamental – perhaps the fundamental – difference
between a planned and a market economy.
Hayek continues to be the most eloquent expositor of the concept of the market as a process
of discovery. His argument was a priori , but vindicated by the failures of the eastern bloc in
the post-war era. These planned economies failed in the development, not just of consumer
products, but of business methods. Their technological development was disappointing in
almost all not related to military hardware. Centralised systems experiment too little. They find
reasons why new proposals will fail – and mostly they are right in finding reasons why they will
fail. Most experiments do fail. Market economies thrive on a continued supply of
unreasonable optimism. And when, occasionally, the experiments of entrepreneurs succeed,
they are quickly imitated. It is a sad fact of the market economy that even for innovations that
are commercially successful, few are commercially successful for the innovator.
10
11. THE MARKET ECONOMY
If market economies are better than planned societies at the origination and diffusion of new
ideas, they are also better at disposing of failed ideas. Honest feedback is not welcome in large
bureaucracies. In authoritarian regimes, such feedback can be fatal to the person who delivers
it. In less draconian contexts, unwanted messages can be fatal to careers. And when I
describe large bureaucracies here, I refer just as much about large private bureaucracies as
large public ones. Disruptive innovations most often come to market through new entrants –
from Google, EasyJet, Amazon. Incumbents have good reasons to be suspicious of novelty
and protective of their established markets and activities.
The health of the market economy depends, therefore, on constant replenishment of the
business sector by new entry. If, as planner or sponsoring department, you had been planning
the future of the computer industry in the 1970s, would you have asked Bill Gates and Paul
Allen?, If, as planner or sponsoring department, you had been planning the future of aviation
in the 1980s, would you have asked Stelios Haji-Ioannou? If, as planner or sponsoring
department, you had been planning the future of retailing in the 1990s would you have asked
Jeff Bezos? Of course not: whether you were the politburo or permanent secretary you would
have asked men in suits like yourself.
Watching the impact of electronics and the internet on children and grandchildren, makers of
business and public policy have at least understood these issues. Committees of the middle-
aged Twitter about technology like embarrassing adults trying to have fun at the teenagers’
disco. But, like those adults at the party, we are not really serious. Whether planners or
governments of a market economy, we see industries through the eyes of established firms in
the industry. And in doing so miss the pluralism that is the market economy’s central dynamic.
MARKETS RESTRAIN CONCENTRATIONS OF POWER
That leads directly to the third group of reasons for the superior performance of market
economies. If I were to offer a one sentence description of why some countries are poor and
others rich, it would be that the politics and economics of poor countries are dominated by
rent-seeking and the politics and economics of rich countries are not. Rent seeking is the
process by which the ambitious find it more rewarding to batten on the wealth created by
other people than to create it themselves.
Rent seeking takes, and has taken, many forms – castles on the Rhine, the Wars of the Roses;
ten per cent on arms sales, or seven per cent on new issues: awarding yourself control over
former state assets, stealing the revenues from your country’s resources deposits, seeking
protection from foreign competition, blocking market access by new entrants; winning
11
12. SOCIAL MARKET FOUNDATION
sinecures or overpaid positions by ingratiating oneself with public servants or corporate
employees. The mechanisms of rent-seeking range from the application of armed force to
victory in democratic election; the methods pursued range from lobbying on Capitol Hill and
in the restaurants of Brussels, through access to the King or the Chief Executive.
But while rent seeking is ineradicable, we can have more of it, or less. Politics everywhere used
to be dominated by rent seeking; factions would battle for control of the state and when they
won such control would use it to steal as much as they could get their hands on. In much of
the world, it is like that still. ‘It’s Our Turn to Eat’ is the stomach churning title of one
fascinating recent book about the corrupt – and moderately - democratic politics of modern
Kenya. We have come to recognise the resource curse – wealth from national resources does
more harm than good in many countries because of the rent-seeking it attracts – and foreign
aid may have some of the same characteristics. But in Western Europe, at least, corrupt politics
has ceased to be an avenue for rent-seeking.
The ability of a political/economic system to resist rent seeking depends on the degree of
economic decentralisation. Individuals will try to get their hands on the rents which
concentrations of power attract whether they are found in the public sector, in private
businesses, or in groups of private business. The wider the extent of the opportunities this
created, the greater the tendency for individuals to gain wealth and influence for themselves
by attaching themselves to power rather than exploiting their own individual talents and by
developing distinctive capabilities in their own economic activities.
There is a strong tendency for private concentration of economic power to be self-reinforcing.
This problem was widely recognised in America’s ‘gilded age’ at the end of the nineteenth
century. The well-founded fear was that the new mega-rich – the Rockefellers, the Carnegies,
the Vanderbilts – would use their wealth to enhance their political influence and hence
enhance their economic power still further, subverting both the market economy and the
democratic process. These concerns were the origin of anti-trust legislation, a point today
often forgotten. The process that concerned Americans then is the problem we see in Russia –
and elsewhere in the world – today.
The ability of a market economy to channel the desire for acquisition into channels that create
wealth rather than extract it, depends on measures both to prevent the concentration of
economic power and to limit the terms of access to such concentration. These are constraints
on the economic power of the state: constraint on the concentration of economic power in
large businesses: constant vigilance at the boundaries between the state and business: and a
mixture of external supervision and internal restraint which prevents individuals who pull
levers of economic power from using these levers to direct renting to themselves.

13. THE MARKET ECONOMY
THE CURRENT POLITICS OF THE MARKETPLACE
Because the last decades have confused a pro-business stance with a pro-market stance, we
have emphasised some of these conditions at the expense of others. Western – and especially
Anglo-Saxon societies - have constrained the economic role of the state. These measures have
reduced the scope of one focus of rent-seeking, that by organised groups of public
employees. A substantial element of such rent-seeking remains in areas that remain
inescapably within the public sector.
But the larger issue is the concentration of power of large business, or groups of large
businesses, and the use of the leverage that power gives to strengthen established positions
and enhance that economic and political power still further. The topical – and most important
example is the financial services industry.
The problems of that industry are too familiar to require much elaboration. The governments
of the world have pumped unbelievably large amounts of money into the system. Directly
through recapitalisation and purchase or underwriting of so-called toxic assets: more
substantially if indirectly through wide-ranging implicit and explicit guarantees of liabilities.
Even if these explicit guarantees expire, a ‘too big to fail’ doctrine has been established which
means that implicit guarantees persist indefinitely. The criteria needed to qualify for these
guarantees are, essentially, that the firm is large, well established, and unsuccessful
commercially. It is difficult to think of a policy more directly contradictory to the dynamic of
the market economy.
Behind that lies the central fact of modern political life – that the financial services industry,
and particularly its investment banking arm, has become the most powerful political force in
Britain and the United States. The reasons are clear enough: the rents available in the financial
sector have attracted much of the ablest talent in the two countries and created a generation
of financiers who are both smart and wealthy.
Our policies err focussing on the first pillar – prices as signals. They underestimate the strength
of markets as a process of discovery, and the vital political and economic role of markets in
restraining concentrations of economic power. Markets are not a well oiled physical machine:
they are a constantly changing, adaptive biological system. Pluralism is their motive force,
their essence chaotic, their development inherently uncertain. If we could predict the
evolution of markets, we would not need markets in the first place.

16. In the second of a series of essays to mark the 21st anniversary of the Social
Market Foundation, John Kay looks back at the triumph of the market economy
since the fall of the Berlin Wall. Kay attributes this triumph to the role of the
price mechanism, ‘markets as a process of discovery’, and the diffusion of
political and economic power with which markets are associated.
Kay argues that too much emphasis has been placed on the first of these
elements with the result that both supporters and critics of the market
economy have often confused policies that are pro-business with policies that
are pro-market. That confusion has both undermined the social and political
legitimacy of the market economy, and led to serious policy errors that follow
from a mistaken and incomplete understanding of how a market economy
