14.1 Economic Organization and the Division of Labour
The division of labour entails the problem of economic
coordination. For reasons of preference
and efficiency, among others, the various members of society specialize in
performing distinct activities. These
specialized activities must be coordinated in such a way that a useful overall
result is obtained. The three modes of
control discussed in the context of the firm - exchange, command, and custom - are
used not only for purposes internal to the organization of the firm, but for
the good of society as a whole. [1] Thus, the
executive branch of government relies on command, and so does the military. Social interaction is governed by customary
and legal rules that are the social counterparts of duty at the level of the
firm. The system of markets, finally,
coordinates production and consumption across firms and consumers through the
mechanisms of exchange.
It is a Marxian misapprehension to think that the
social division of labour is organized exclusively by the market and the
division of labour within firms is organized exclusively by command. [2] Both the

12.4). This view is shared by many
non-Marxists and is reflected, e.g., in the title Markets and Hierarchies chosen
by O. E. Williamson (1975).

firm and the market rely on custom. All three control modes - custom, command, and
exchange - work in various combinations, both at firm level and society level.
With regard to economic activity, the firm and the
market are complementary institutions for organizing the division of labour. In order to understand the emergence of firms
in a market system, it is necessary to analyse which kinds of activities
are better organized within firms, and which by markets. Those kinds of coordination better performed
by the market ought to be left to the market; those better performed without
market interference, on the other hand, will give rise to the formation of
firms. Accordingly, the fundamental
coordination problem associated with the division of labour entails both the
theory of the firm and the theory of the market.
This chapter is devoted to the problem of the division
of labour, and the conditions under which that division of labour is better
organized by the firm or by the market. Firms,
as islands of custom, emerge in the market because coordination by custom is in
many ways more efficient than coordination provided through the market. However, custom has a severe drawback, because
the mutual reinforcement of a system of interlocking customs entails rigidity
and inflexibility. The inherent inertia
of coordination by means of custom renders the firm inferior to the market with
regard to certain types of adaptation and change. The organizational alternative of coordinating
a given task within a firm or through a market may be understood as engendering
institutional competition between these two modes of organization. The institutional mix between firm and market
which emerges in a society may be understood as arising from this competition. The firm thrives on the advantages of custom,
and the market thrives on the flexibility attainable through standardization in
an anonymous setting. In order to better
understand the advantages and short-comings of custom as a device for
organizing the division of labour, the subsequent sections will be devoted to
looking more closely into the coordination problems posed by the division of
labour.

14.2 The Division of Labour and the Extent of the Market
The classic position with regard to the division of
labour is encapsulated in ‘Smith’s theorem’: the division of labour is limited
by the extent of the market. [1] The usual
reading of the theorem, suggested by Smith’s own account, is, however, different.
It may better be phrased as ‘The
division of labour is determined by the extent of the market.’ The two versions should be distinguished.
Smith argues that specialization leads to an increase
in productivity resulting from ‘increasing returns to specialization’. These result from the increasing returns to
scale that occur in performing any task or sub-task. As a consequence, all specialization increases
the productivity of the economy as a whole. If there are two persons who divide their time
equally between producing one unit of good A and one unit of good B, the joint
output will be 2 units of A and 2 units of B. If both of them specialize, however, joint
output increases: the first person produces more than 2 units of A and the
second person will produce more than 2 units of B. They are able to do this because of increasing
returns to scale. This amounts to
increasing returns from specialization.
As to the reasons for increasing returns to
specialization, Adam Smith mentions four of them. The first two are straightforward. One is that specialization leads to improved
dexterity:
A common smith, who, though accustomed to handle the hammer, has never
been used to make nails, will scarce be able to make above two or three hundred
nails a day, and those too very bad ones. A smith who has been accustomed to make nails,
can seldom make more than eight hundred or thousand nails a day. I have seen several boys under twenty years of
age who had never exercised any other trade but that that of making nails and
who could make, each of them, upwards of two thousand three hundred nails a
day. [2]
1. Smith (1776: 17) The name ‘Smith’s theorem’ is due to Stigler
(1951), who interprets it as indicated in the following text. For an interesting discussion of the division
of labour, see Leibenstein (1960: ch. 7); for a good survey of views about the
division of labour, see Groenewegen (1987).
2. Adapted from
Smith (1776: 7-8).
244
The second reason is that time can be saved that would
be required ‘in passing from one sort of work to another’. [1]
The third reason given by Smith is more intricate. It relates to the conditions of technical
progress and the introduction of machinery:
I shall only observe, therefore, that the invention of all those
machines by which labour is so much facilitated and abridged, seems to have
been originally owing to the division of labour. Men are more likely to discover easier and
readier methods of attaining any object, when the whole attention of their
minds is directed towards that single object, than when it is dissipated among
a great variety of things. But in
consequence of the division of labour, the whole of every man’s attention comes
naturally to be directed towards some one very simple object. [2]
The fourth reason that Smith mentions relates to
‘differences in natural talents in different men’. He is, however quite cautious here and adds
that it is in reality ‘much less than we are aware of; and the very different
genius which appears to distinguish men of different professions, when grown up
to maturity, is not upon many occasions so much the cause, as the effect of the
division of labour’. [3]
Adam Smith’s ‘theorem’ results from combining the idea
of increasing returns to specialization with the causal variable of the size of
the market. If a market is small,
specialization in either good A or good B cannot occur. The joiner will produce both window casements
and doors to meet the demand of his village. Although he could produce window casements
more cheaply if they were demanded in larger quantities, the demand is not
large enough to permit specialization. If
the market expands because, say, transportation costs are reduced, conditions may
change. It may then be worthwhile for
joiner A to specialize in window casements and supply customers in the
surrounding villages as
1. Smith (1776: 8).
2. Smith (1776: 9) Smith develops
the idea further by introducing more specialists (‘philosophers and
machine-makers’), who exploit further advantages of specialization along the
same lines.
3. Smith (1776: 15).
245
well; the other joiners then may each specialize in supplying the
enlarged market with other specific items.
14.3 Fixed Costs
and Increasing Returns from Specialization
It is illuminating to rephrase some aspects of the
reasons for increasing returns to specialization, as given by Smith, in terms
of fixed costs. Fixed costs are costs
that are independent of the level of production. They are setup costs incurred while establishing
the possibility to produce. Many aspects
of the arguments given by Smith relate to fixed costs in a straightforward way,
but this view also sheds light on some other aspects of increasing returns from
specialization.
Explicit training costs can be viewed as fixed costs. A modern statement stresses this aspect: ‘A
specialist such as a surgeon is an indivisible resource. He has a training of 10 years and then operates
for 30 years. He cannot simply be
replaced by two half surgeons who each are trained for 5 years and operate on
half as many patients only every other day’. [1]
The fixed-cost parlance would also cover costs related
to machinery. A joiner who builds window
frames only occasionally will not find it worthwhile to buy specialized
machinery; a carpenter specializing in windows, on the other hand, would be
much more likely to make regular use of such equipment. Specialization renders it worthwhile to invest
in specialist machinery. This leads to
additional returns from specialization that go beyond the aforementioned
increase in dexterity.
Important fixed costs relate to information and
innovation. A lawyer specializing in
certain cases may find it worthwhile to subscribe to a specialized data bank
for finding the relevant precedents quickly, but a less specialized lawyer
would not find such a subscription worthwhile. Similarly, the design of a machine requires
research and development. This entails
fixed costs, and
1. von Weizsacker (1991: 106).
246
it will be worthwhile contemplating such a project only if a sufficient
number of machines is to be produced. It
should also be noted that the greater specialization of joiners would be likely
to increase the demand for specialized machinery and would therefore make it
more worthwhile to supply it.
Other important fixed costs relate to the
establishment of organization and routines. Investment in ‘organization’ is indeed of the
utmost importance. [1] It is of the
same nature as any other fixed-cost investment. Firms that specialize in certain products will
also have an incentive to develop routines that are specifically tailored to
their production. This will lead, again,
to increasing returns from specialization.
The case of on-the-job skill acquisition, as discussed
by Smith, also fits into the fixed-cost framework, although on-the-job training
also raises more intricate issues. Nevertheless, the costs of acquiring a skill
have to be considered as fixed costs. [2]
14.4 The Division
of Labour and the Nature of the Task
Smith’s argument presupposes that gains from
specialization will accrue whenever the division of labour is deepened. This is not true. Many tasks cannot usefully be further
subdivided. There is no sense in
subdividing the writing of a poem such that everybody specializes in certain
rhymes; or in subdividing the writing of computer software such that each
programmer specializes in writing one single line of code. Several factors limit the division of labour,
and the extent of the market is only one of them. Another relates to the nature of the task.
Some tasks simply cannot be subdivided. This applies to tasks that are of a sequential
nature, where each step requires knowledge of previous steps. Distributing steps among different workers
would require the transmission of information about the previous
1. Marshall (1890:
138-9) stressed this rightly by describing ‘organization’ as one of the
fundamental ‘agents of production’, along with land, labour, and capital.
2. This is elaborated
in Becker (1962).
247
steps. This may be more
difficult and more time-consuming than actually performing these steps. If a programmer has started to write a
routine, it will be much easier for him to complete it than for somebody else
to do so. The errors that can occur in
the communication process will be avoided. Such continuity has been stressed in software
engineering:
Men and months are interchangeable commodities only when a task can be
partitioned among many workers with no communication among them. This is true for reaping wheat or picking
cotton; it is not even approximately true of systems programming.
When a task cannot be partitioned because of
sequential constraints, the application of more effort has no effect on the
schedule... Many software tasks have this characteristic because of the
sequential nature of debugging. [1]
But even if tasks can be subdivided, this does not necessarily increase
overall output, because a finer subdivision will necessitate more coordination.
This aspect has been neglected by Adam
Smith, but has been recognized in the literature:
When tasks require coordination of a delicate and complicated variety,
the individual worker may be more efficient if he performs a variety of tasks
because the loss from non-specialisation is offset by the gains from
coordination. We expect a better
painting from a single good artist, than if the world’s best specialist in
clouds does a portion of the picture, and the world’s best specialist in trees
another portion. [2]
The importance of this observation is usually not appreciated fully, in
spite of the literature on transaction costs. It is not of marginal concern, but rather constitutes
one of the central problems posed by the division of labour. Software engineering illustrates this, once
again, and in a drastic way:
In tasks that can be partitioned but which require communication among
subtasks, the effort of communication must be added to the amount of work to be
done. Therefore the best that can be
done is somewhat poorer than an even trade of men for months.
The added burden of communication is made up of two
parts, training
1. Brooks (1975: 16-17).
2. Stigler (1952: 140);
see also Stigler (1966: 168).
248
and intercommunication. Each
worker must be trained in the technology, the goals of the effort, the overall
strategy, and the plan of work. This
training cannot be partitioned, so this part of the added effort varies
linearly with the number of workers.
Intercommunication is worse. If each part of the task must be separately
coordinated with each other part, the effort increases n(n-1)/2. Three workers require three times as much
pairwise intercommunication as two; four require six times as much as two. If, moreover, there need to be conferences
among three, four, etc., workers to resolve things jointly, matters get worse
yet...
Since software construction is inherently a system
effort - an exercise in complex interrelationships - communication effort is
great, and it quickly dominates the decrease in individual task time brought
about by partitioning. Adding more men
then lengthens, not shortens, the schedule. [1]
The costs involved here are sometimes immense, and the problems
generated by the difficulty of coordination are equally tremendous. [2]
In contexts that require much interaction, the problem
of the division of labour poses itself in a way that differs from what Smith
has envisaged. In order to appreciate
the relative advantages of custom and the market in coordinating tasks of this
type, it is useful to look more closely into the issues of timing,
separability, and conceptual integrity as determinants of the nature of the
task.
The issue may be phrased in a slightly more general
fashion by introducing a rough classification between tasks, according to their
nature. To fix the ideas, let us suppose
that each task may be conceived of as involving a number of actions a, b, c,..
. These actions are subdivisions of tasks. The task of screwing two pieces of wood
together may be seen as a sequence focusing on the action
1. Brooks (1975:
17-19).
2. See Brooks (1975:
31). Brooks is known as the ‘father
of the OS/360’. He was project manager
for the development of this software system and later project manager during
the design phase.
249
of turning the screwdriver once. By repeating this action, the task is
eventually completed. ‘Action’ refers in
the following to an action relative to a task. The term is not meant to denote some ‘action
atom’ that cannot be subdivided further. It does seem not useful to assume that such
atoms exist. The turning of the screwdriver
may be viewed as a task in its own right, comprising actions of several
fingers, the arm, and the body, for instance, and this could be subdivided even
further.
Given that a task comprises several actions, a distinction
between different tasks may be drawn according to the timing that is
required to perform the actions. A
sequential task requires the actions a, b, c, to be performed in
sequence. [1] An example
would be the weaving of a fabric, where one thread has to follow the other and
where it is not possible (or is prohibitively costly), for technological
reasons, to leave some gaps and fill them in later. Another example would be the sequence of
producing and testing an item: the test cannot be performed before the
production task has been completed.
A simultaneous task requires that actions a, b, c, are performed simultaneously in
close coordination. Workers who want to
lift a beam together have to concert their action. The performance of a piece of music by an
orchestra requires much more than each player playing his part flawlessly: the
musicians have to play their parts synchronously.
There are also tasks in which the actions required can
be performed quite independently. These
are temporarily independent tasks; entering numbers into a data bank or
writing entries for a dictionary are examples.
In reality, no task fits neatly into one or the other
category. Distinctions may be drawn,
however, along the time dimension. The
categories introduced above are intended to highlight what is involved here.
1. See also Leibenstein (1960: 111-15).
250
14.6 Separability and Interdependence
Another way of distinguishing tasks relates to
intrinsic interdependence. This aspect
is of great importance for the present purposes.
Consider first a sequential task. Actions a and b have been
performed, and an intermediate product B is obtained. By applying action c, this intermediate
product can be transformed into another intermediate product C, and so
forth. Often it is unnecessary to know
specifics about actions a and b in order to perform c. All information is contained in the
intermediate product B. Such a
task may be denoted as separable.
A nice illustration of separable tasks is given by
Demsetz: ‘The economical use of industrial chemicals by steel firms does not
require transfer of knowledge of how these chemicals are produced; similarly,
the use of steel by industrial chemical firms does not require transfer of
knowledge of how steel is produced.’ [1]
Sequential tasks may, however, be far from separable. Adding another line of computer code requires
knowledge of the preceding code. All
preceding actions a and b must be known in order to perform
action c. If the actions of a
sequential task depend on each other in this way, the task is termed an interdependent
task.
The distinction between separable and interdependent
sequential tasks is not a sharp one. In
a sense, the computer program with completed parts a and b may
contain all the information that is necessary to perform action c in an
appropriate manner. The intermediate
product B contains that information, and in a formal sense the task may
appear additive. In order to cope with
this difficulty, interdependence may be conceived as a matter of degree. The larger the information needed about
previous production steps, the stronger is this interdependence.
But even if all information required for taking step c
were to be contained in the intermediate product B, the worker in
charge of
1. Demsetz (1988: 159).
Demsetz (1988: 160) has stressed this
informational aspect in his view of the firm: ‘Roughly speaking... the vertical
boundaries of a firm are determined by the economies of conservation of expenditures
on knowledge.’
251
taking step c would have to retrieve the relevant information
about the previous actions from the intermediate product B. For instance, he would have to try to
comprehend the code written by the previous programmers. In such a case, it might be cheaper to have
the worker who had performed the previous steps also perform the next step c.
This would save the costs that arise
from retrieval, and would reduce the danger of errors. This may be considered as still another form
of interdependence.
It may be the case, however, that the intermediate
product does not contain enough clues to retrieve the information that
is necessary to undertake step c. It
may even be cheaper to perform steps a and b again rather than to
try unravel the plan that gave rise to the intermediate product B. This too would be a case of
interdependence.
Consider next simultaneous tasks. Again, these may be either separable or
interdependent. A separable task is one
where each action can be performed without any technical knowledge of the other
actions; action c can be executed without knowing precisely how a and
b are performed. Measurements
performed simultaneously at different points of the globe are separable. In such cases coordination is simple, as only
a timing device is needed. Each
measurement can be made independently, and the way in which the measurements
are made is inessential. It is only
important that each observer has an accurate watch, and that he is instructed
about the time of measurement.
Simultaneous tasks may, however, be strongly
interdependent. A piece of chamber music
requires each player to react instantaneously to the playing of his partners. Each nuance of articulation has to be
perceived by each player, and each has to adjust his playing in order to
achieve a perceptual unity and coherence. It takes many years of continuous practice for
an ensemble to perfect such a degree of coordination.
Software engineering is no less demanding. Large projects have to be split up into
modules that are developed simultaneously. If module a uses subroutines of module b
and module b uses sub-routines of module a, separability may
be achieved by standardi-
252
zation. The standards must,
however, be established in such a way that they can be implemented. Typically, they have to be changed to
incorporate new developments. This
cannot be done without intense interaction.
With regard to temporarily independent tasks, and in
order to exhaust the classification, there may again be either separability or
interdependence. If each individual
action does not require knowledge about the other actions, the task is
separable; if each task requires knowledge about the other tasks, the task is
interdependent. In many cases
interdependence will lead to simultaneity, but this will not always be the
result. The task of filling three
circles with three different colours is, in a way, both temporarily independent
- because the sequence does not matter - and interdependent - because the
filling of each circle requires knowledge about the colours of the circles
already being filled. Yet each worker
can do his job whenever he likes.
14.7 Conceptual
Integrity and Clarity
Interdependence may also be generated beyond the temporal
dimension through the requirement of conceptual integrity. This requirement has been stressed in particular
in software engineering, but it is of general relevance:
Most European cathedrals show differences in plan or architectural
style between parts built in different generations by different builders. The later builders were tempted to ‘improve’
upon the designs of earlier ones, … So
the peaceful Norman transept abuts and contradicts the soaring Gothic nave .
Against these, the architectural unity of Reims stands
in glorious contrast. The joy that stirs
the beholder comes as much from the integrity of the design, as from any
particular excellencies. As the
guidebook tells us, this integrity was achieved by the self-abnegation of eight
generations of builders, each of whom sacrificed some of his ideas so that the
whole might be of pure design...
Even though they have not taken centuries to build,
most programming systems reflect conceptual disunity far worse than that of
cathedrals. Usually this arises not from
a succession of master designers, but from the separation of design into many
tasks done by many men.
253
I will contend that conceptual integrity is the most
important consideration in system design... Simplicity is not enough. Mooers’s TRAC language and Algol 68 achieve
simplicity as measured by the number of distinct elementary concepts. They are not, however, straight-forward. The expression of the things one wants to
do often requires involuted and unexpected combinations... It is not enough to learn the elements and
rules of combinations; one must also learn the idiomatic usage, a whole lore of
how the elements are combined in practice. Simplicity and straightforwardness proceed
from conceptual integrity. Each part
must reflect the same philosophies and the same balancing of desiderata. Every part must even use the same techniques
in syntax and analogous notions in semantics. Ease of use, then, dictates unity of design,
conceptual integrity. [1]
Overall clarity is, thus, an important functional requirement for a
piece of software. This requirement ties
the different parts together and creates strong interdependence in programming.
It should not be surprising that clarity requirements
enter here. The principles that govern
human behaviour in playing a game like Eleusis and those that underlie the
formation of custom are equally relevant for dealing with a computer language,
or any other advanced item. [2] It is for this
reason that clarity is an important aspect of functionality. With respect to everyday staple products such
as cars, computers, or television sets, this may just appear as ‘good handling’
and straightforward operation to the consumer, but it is important for assembly
and maintenance. Unclear design will
translate into high costs of repair and unreliability after repair. It will make for a poor product.
Consider now the organization of the division of
labour. The fundamental question is,
which tasks are most economically coordinated through the market, and which are
more logically coordinated within firms?
For tasks that involve substantive interdependence,
the market is

2. The card game
Eleusis has been described in S. 7.2.
254
a poor instrument for coordination.
‘Jointness of effort and activities... involves more cooperation among
individuals than that of simple market exchange.’ [1] While the interdependence may be reduced by
defining standards for interfaces between production steps, this will not
always be feasible, and it may be costly. Yet even such standards will not necessarily
lead to the formation of markets. Decentralization
of interdependent tasks may also occur on a large scale through custom. The rules of traffic illustrate a decentralization
of interconnected activities without a firm or a market.
But even separable tasks may be organized more easily
within a firm than through a market. All
the incentives that the market provides could also, theoretically speaking, be
provided within the firm, while the overhead of additional marketing costs
could be saved. Coordination could only
be improved, because the firm as an organization offers a vastly richer menu of
coordination devices than does the market. [2] It is easier
to develop specific routines, or particular languages, within the firm than in
the market, and informal ways of cooperation are more readily available. [3] Inserting a market between two steps
introduces marketing costs into the production process and drastically reduces
the possibilities of coordination by other means.
Thus, while the market has strong drawbacks with
regard to interdependent tasks, it is also difficult to pinpoint the advantages
of market organization for separable tasks. Instead of asking ‘why firms?’ the difficult
question to answer is ‘why markets?’ [4]
1. Alchian (1991:
233). Demsetz (1988: 157-62) has
articulated this view in terms of information costs.
2. ‘Perhaps the most
distinctive advantage of the firm, however, is the wider variety and greater
sensitivity of control instruments that are available for enforcing intrafirm
in comparison with interfirm activities’. (Williamson 1971: 113).
3. This has been
stressed in particular by Hirschman’s (1970) insistence that ‘voice’ be granted
an important role in the theory of the firm.
4. This has been
stressed by various authors, e.g. Coase (1937: 43: ‘Why is not all production
carried on by one big firm?’); 0. E. Williamson (1985: 132-8: ‘A Chronic
Puzzle’), Von Weizsacker (1991: 100: ‘It is difficult to prove, rather than
simply state, that there are functions performed better by the market rather
than any possible alternative.’). The problem
is sometimes referred to as ‘Williamson’s puzzle’ or the ‘centralization
paradox’; see Stiglitz (1991: 18). O. E.
Williamson (1985: ch. 6) and, more recently, Putterman (1995) provide
excellent discussions of various facets of the problem. My concern here relates to more general
aspects and the nature of custom.
255
In answering the question ‘why firms?’, Coase rejected
the idea that people might prefer to work in firms rather than for the
market: ‘Such individuals would accept less in order to work under someone, and
firms would arise naturally from this. But
it would appear that this cannot be a very important reason, for it would
rather seem that the opposite tendency is operating if one judges from the
stress normally laid on the advantage of “being one’s own master”.’ [1] This suggests that people may have a
preference for market transactions. However,
at least if real-world experience may be taken at face value, this does not
seem to be true. The misleading
conclusion arises because Coase stresses command rather than custom as the
distinguishing mark of the firm. A job
offers a range of competencies and responsibilities, and the worker is, within
the confines of his job, his ‘own master’. He may actually perceive more autonomy in
performing his job than he would have in organizing his work as an
entrepreneur. If the firm were his own,
he would then also have to be alert to changes in circumstances and market
conditions. The desire of housewives to
obtain jobs seems to flow from the perception of personal autonomy in a job. Further, the firm provides an environment for
social interaction which is sometimes valued highly; the arguments against
‘telecommuting’ (working with a computer at home) illustrate this. In the end, there seems to be a preference for
working in firms. This renders the
question ‘why markets?’ even harder to answer.
The firm, as a system of highly integrated routines,
reward systems, and command structures, benefits from integration. The productivity gains obtainable are due not
only to improved coordination by means of specialized and well-matched
routines, languages, and tacit ways of cooperation, but also to the strong
impact on motivation arising from the formation of a group. The
1. Coase (1937: 38).
256
firm generates group forces that emanate from the same clarification
processes that lead to interlocking customs. A set of interlocking customs provides many
diffuse reasons for working and thinking in a certain way. Self-attribution will not be able to link
behaviour to such a diffuse pattern of causes. Thus, self-attribution will focus on intrinsic
motivation and will generate corresponding attitudes and motives. [1] In this way, ‘corporate culture’ - or, better,
‘corporate custom’ - shapes cognition and motivation. It is a productive asset and arises from the
same forces that shape different cultures. Such group forces can be fairly strong. (They occasionally cause war.) Firms make use
of them. [2]
But a system of highly integrated routines, rewards,
and command structures has drawbacks because it is highly integrated. While integration shapes motivation and
bundles information in a most parsimonious manner, it ties everything together
and in that way creates rigidity. What
has been said about interlocking customs applies here, too. [3] Coordination by routines may be efficient, but
it requires the routines themselves to be inflexible.
Such inflexibility relates to the rules rather than to
the actions that they generate. A firm
may respond very quickly to changes in circumstances as long as this change can
be handled by the prevailing routines and command structures. An army is organized in order to respond
quickly, but it does not use the market mechanism to achieve that aim: rather,
the organization is designed for that purpose. The routines and command structures are themselves
fairly rigid.
Integration binds together everything within an
organization. Consider pay. All textbooks on compensation stress the
1. See S. 9.7.
2. On the foundation of
groups, see Asch (1952: p. III and V). Such group phenomena are obviously important
and have been emphasized in quite early writings, as can be seen from the
quotation of Marx given in fn. 1, p. 241 above. Yet the theory of the firm has not taken
account of this, and has not even tried to refute group effects on factual,
rather than paradigmatic, grounds.
3. See S. 10.8.
257
overwhelming importance of ‘internal consistency’, and practitioners
agree. The following quotation from a
textbook on compensation illustrates this:
Internal consistency refers to pay relationships among jobs or skill
levels within a single organization. It is one of the basic compensation policies. It involves equal pay for jobs of equal worth
and acceptable pay differentials for work of unequal worth. But internal consistency involves more than
the pay structure. Often called internal
equity, a policy that emphasizes internal consistency places importance on the
inner workings, the relationships and pressures found within an organization. Consequently it includes concerns for the
fairness of the procedures used to establish the pay structure, as well as the
structure itself. [1]
The phenomenon itself hardly needs further elaboration. The various techniques used to determine
compensation demonstrate the practical importance of these considerations. The equity standards are undeniably of great
importance within organizations. They
cannot be interpreted merely as surface appearances of underlying economic
considerations. Clarity requirements are
not reducible to scarcity arguments or to the logic of rationality. A 50-50 split of outcomes, as used in
the Halsley method of employee compensation, can hardly be explained in terms
of scarcity and incentives alone: [2] it relates to symmetry and clarity. Similar observations apply to a host of other
compensation methods.
These remarks should not be taken to suggest that
incentives and scarcity do not play a role: incentives and scarcity are
obviously of the greatest importance. The
point is rather that clarity requirements constrain the possibilities of
obtaining the full and complete return from these instrumental considerations. The costs of custom emerge, just as do the
benefits, from the need for coherence.
Many examples illustrate this feature. Wages for the same type of work vary
systematically across industries and firms. [3] Trans-

portation may be contracted out in order to avoid compensating the
truck drivers according to the firm’s own corporate culture; [1] cleaning,
maintenance, and service may be contracted out for similar reasons. Some takeovers occur because the merger
largely voids the compensation practices of the firm that is swallowed up. This may be a profitable and painless way of
replacing one set of constraints for another. [2]
Other constraints resulting from integration relate to
standards of quality. Work routines are
geared to such standards. Typically,
each firm predominantly serves a particular quality segment of the market even
in cases where substantial economies could be expected from integrating
high-quality production lines with low-quality products. [3]
These consistency constraints are well known, but less
well understood. Why, it may be asked,
are they so important? It has been
shown, after all, that people get used to nearly everything. Psychological
studies of adaptation
suggest that any stable state of affairs tends to become acceptable
eventually, at least in the sense that alternatives to it no longer readily
come to mind. Terms of exchange that are
initially seen as unfair may in time acquire the status of a reference
transaction... The gap between what people consider fair and the behaviour they
expect in the marketplace tends to be rather small. [4]
Custom is adaptive, after all. This
argument is misleading. Even if workers
can adapt to the most unintuitive regulations, this attempt is bound to create
control problems. If the set of routines
is augmented by a routine that embodies a different philosophy and style, each
of the earlier established routines will lose some of its imperative character
and a part of its impact on behaviour. Similar
effects are well-known in software engineering. An entire program may suffer if features are
added that do not ‘fit’; then,

whenever a further feature is added, it is uncertain whether it follows
the old style or the new one. The delays
and errors induced by this uncertainty may easily outweigh the benefits of the
added features. [1] Similarly, the
rule to do one job quickly and the other with the utmost scrutiny will induce
workers to perceive the approach to work as somewhat arbitrary. The labour force will not easily develop a
coherent style, an appropriate set of habits, and a functional structure of
motivation. Furthermore, a mixing of
principles of compensation will put the entire compensation policy of the firm
at risk. Each worker will perceive the
benefits that would accrue to him if he were treated like the others in some
particular aspects. He will not consider
that he may be benefiting in other dimensions. This creates internal stress and is
detrimental to corporate custom.
14.11 The Use of
Knowledge in Society
The market has been interpreted as a system that
enables economic agents to make use of widely dispersed knowledge in a
parsimonious manner. Prices serve as
signals that encode all relevant information about scarcities and make this
knowledge available throughout the social and economic system. It is, thus, not necessary to enquire further
about specific scarcities, wants, or production conditions. [2]
The earlier discussion of the role of routines within
firms has stressed efficiency aspects of coordination by custom in a parallel
manner. [3] Routines are maintained by
following them; what is not repeated is forgotten. This implies that only useful knowledge
survives. The routines embody that
knowledge, even if the individuals are not aware of the fact. By allocating responsibilities to job holders,
the idiosyncratic expertise of these workers can be used to the benefit of the
organization. In this sense, a
firm-specific set of

2. Hayek (1945).
3. See S. 13.11. Demsetz (1988: ch. 9) has argued e.g. that
firms can thrive in a market environment because they are more efficient in
economizing on information flows; see also the discussion of separability and
independence in S. 14.6 above.
260
customs may be conceived as a mechanism that enables the members of the
firm to make coordinated use of widely dispersed knowledge.
This observation holds true in society as well. There are national economies that are
coordinated mainly by custom. People
follow the established behavioural patterns, and an overall coordination is
achieved without any explicit awareness.
Each individual needs only to know how to perform his allotted task and
to follow the role prescription. His
entitlements and obligations, his duties and routines transmit all the
information that is necessary for him to coordinate social and economic
activity. The market mechanism is not
unique in this respect. Hayek, who
(following Menger) developed the view of the price system as making use of
dispersed information, was quite clear about this:
We make constant use of formulas, symbols and rules whose meaning we do
not understand and through the use of which we avail ourselves of the
assistance of knowledge which individually we do not possess... The price
system is just one of those formations which man has learned to use. [1]
Custom is another formation of this kind. If the market is a marvel, custom is a marvel,
too.
Furthermore, command may also be understood as
economizing on information. By
centralizing the power of decision-making, it is possible to set up an
efficient means of gathering information, and to distribute to the individual
actors only those pieces of information that are necessary for them to take the
appropriate action.
Thus, all three control modes - exchange, command, and
custom - can be viewed as economizing on the use and distribution of knowledge.
The market is not necessarily the most
efficient way to deal with informational issues. Rather, it is conceivable that there are
several kinds of information, and that the different control modes have
specific advantages or drawbacks with respect to gathering, channelling, and
distributing that intelligence.
1. Hayek (1945: 528).
261
It is, however, misleading to put exclusive stress on
the informational aspects of economic allocation mechanisms. Motivation is equally important in the
economy.
It has been argued that the problem of economic
coordination arises only under conditions of change. [1] Under stationary conditions, all transactions
are repeated over and over, and the task of coordination vanishes. Once a transaction pattern is established, no
further need for coordination arises. Mere
repetition will suffice to organize the division of labour.
The organization of the division of labour becomes
crucial - and becomes intricate under conditions of change. Change necessitates adjustment. It therefore becomes important to understand
how the economic organization of society generates and digests the change that
is needed.
The division of labour within a given society will
rely on certain organizational structures which are fixed in the short run. This holds true for markets, hierarchies, and
custom. Each of these control modes is
characterized by a certain rigidity in the underlying rule system. This renders it possible to cope with certain
types of change but not with others.
Consider markets. They work best with standardized products,
because standardization renders it unnecessary to evaluate and communicate
quality parameters. More generally, it
has been argued that ‘for anything approaching perfect competition to exist, an
intricate system of rules and regulations would normally be needed’. [2] Commodity and stock exchanges provide
examples.
Any hierarchical system of command, moreover, depends
on a certain institutional structure. Competencies must be defined, and chains of
command determined. In a similar way,
control by custom relies on fixities of behavioural patterns.
1. Hayek (1945: 524),
von Weizsacker (1991: 102-3,109-10).
2. Coase (1988: 9).
262
Thus, all three modes of control exhibit rigidity in
some dimensions and flexibility in others. This suggests that each of the control modes
may enjoy a differential advantage in coping with certain types of
change. Markets, for example, can cope
more easily with changing demands and supplies, whereas hierarchies and
customary forms of organization may find it more difficult to digest such
changes. [1] Changing traffic flows can be
better coordinated by a system of traffic rules rather than by the auctioning
of priority rights. Fires and other
disasters can be better dealt with by a hierarchical organization relying on
command than by prices and markets designed to allocate rescue forces.
The organization of interdependent tasks poses
difficulties for the market. The set of
instruments available for direct coordination within and between firms is much
richer than that available in the market. On the other hand, the market, in spite of
informational shortfalls, is better for organizing independent tasks because it
unleashes the forces of competition. Through competition, it overcomes the rigidity
of custom that impedes dynamic advance in closely knit organizations. [2]
Yet the perceived interdependency of tasks can
attenuate over time. Once routinization
takes place, it leads to a standardization of task interfaces. Standardization greatly reduces the need for
personal communication. Each task module
becomes more separable (and, possibly, internally more interdependent). In this way, the use of the market as a
coordination device is rendered feasible.
The picture emerging from this discussion is as
follows. New technological developments
are organized first within firms or as joint ventures between firms,
without strong reliance on the market. This
is because it is difficult to use the market for coordination purposes for
entirely non-standardized and volatile interdependent tasks. In the course of time, the project takes
shape, routinization develops and takes hold, and standardization becomes
possible. This reduces task
interdependencies, which in
1. However, the
internal organization of firms may respond to different challenges. Burns (1963) has argued, for instance, that
change requires an ‘organismic’ rather than a ‘mechanistic’ organization
structure.
2. See S. 14.8-14.10.
263
turn renders it increasingly advantageous to introduce the market as a
coordination device for organizing the division of labour. There emerges a tendency to organize
non-standardized change within firms, and standardized change through the
market. [1] Firms are, so to speak, the
nurseries for new projects. Once the
projects have achieved an independent identity, they will spin off as separate
firms. Those firms will then develop a
special organizational culture and a special set of customs of their own.
14.13 The Firm, the
Market, and the Division of Labour
The clarity view thus implies a view about the
division of labour between the firm and the market. Both the firm and the market rely on exchange,
command, and custom, but the firm permits tight integration and the development
of specialized customs. This eases
production and enhances motivation. Yet
the tight integration within the firm comes at the cost of internal rigidity. The mutual adjustment of routines, command
structures, and internal pricing schemes renders it difficult to implement
change. Market interaction is less
specialized and unleashes competitive forces to overcome organizational
inertia.
The argument comes down to explaining the organization
of the division of labour within firms and across the market in terms of the
costs and benefits of integration. Where
the benefits of integration outweigh the costs, integration will occur; where
the costs outweigh the benefits, transactions will be carried out in the
market.
The last statement is, by itself, as empty as the
statement that transaction costs determine integration. Yet the view expounded here puts things
differently. It stresses that the
functioning of institutions is not reducible to their various components in an
additive way. The stress on ‘chemical’
interaction is directed
1. A related view has
been outlined by von Weizslcker (1991: 109-13). He argues that firms are better in handling
slow change, and markets are better in handling fast change, and that the
incentive to innovate falls as market concentration increases, giving rise to
an ‘equilibrium theory of innovation’.
265
against nominalistic views of the firm, the market, and other
institutions. The tight alignment of
routines, pricing procedures, and command structures, both across the market
and within firms, emanates from the same tendencies of the human mind that
fashion customs in all spheres of life. They
relate to processes of overall clarification.
