El papel de los servicios en las economías
contemporáneas:
Una formulación consistente dentro de los marcos
de la teoría del valor del trabajo de Marx.
The role of services in contemporary economies:
A consistent formulation within the framework of Marx´s labour
theory of value.

Outline
• Some basics of the labor theory of value
• Input-output tables and Marxian schemes of
reproduction
• Commodities and services
• How to determine the value of services?
• Marx’ prices of production (transformation
problem)
• Empirical results (Austria 2008)
How to analyse the economy?
• Main method:
• Creating Layers of Various Degrees of Abstraction.
– The kind of abstraction is inspired by insights into history and the
logic of the field.
– For logical reasons we take goods (use values) produced under the
existing division of labor as the most abstract layer.
• Layers of high degrees of abstraction do not necessarily
correspond to observed data, but they grasp essential
aspects of reality.
– Analogy to physics: The Law of Gravitation (all bodies fall with the
same rate of acceleration) is contrary to evidence (compare the
fall of a feather and a coin).

Mathematical description in terms of Leontief’s input-output scheme to
represent the economy in terms of use values.
Each row and each column represent one branch of production or firm
It reflects the degree of division of labor.
The matrix of technical coefficients A represents the technology of the
economy. The element aij gives the amount of goods of industry i needed
to produce one unit of output of industry j.
x (output vector) contains all use values produced. It can be split by kind of
use of goods into Ax (demand for intermediate goods) and y (final
demand). The following famous formula is called the primal problem
Ax + y = x
y (final demand) can be split it into c (consumption) and s (surplus product =
capital investment)
y = c + s.
or in matrix notation
Ax + Cx + Sx = x ,
where C, and S represent matrices of consumption coefficients and surplus
coefficients respectively.

Layer 2: Labour values, small commodity production
The dual Leontief model deals with
the unit prices
pA + q = p
p …row vector of unit prices
q … unit value added.
After substitution of q by life unit
labor input l we get the basic formula
how to compute Marx’ labor values v
vA + l = v.
v = l (E – A)-1
We can split l into wages, w, and
profits p and get
l = w + p.
Marx used other symbols
W = C + V + M,
where W is the labor value,
• C constant capital,
• V variable capital and
• M surplus value.
In our notation:
v = vA + w + p.

two aspects of a commodity
Aristotle (“De Rep.” l. i. c. 9, ~ 350 BC):
“The one is peculiar to the object as such, the other is not, as a sandal
which may be worn, and is also exchangeable. Both are uses of the
sandal, for even he who exchanges the sandal for the money or food he
is in want of, makes use of the sandal as a sandal. But not in its natural
way. For it has not been made for the sake of being exchanged”
Adam Smith (The Wealth of Nations, 1776):
“The word value, it is to be observed, has two different meanings, and
sometimes expresses the utility of some particular object, and
sometimes the power of purchasing other goods which the possession
of that object conveys. The one may be called ‘value in use’; the other,
‘value in exchange.’”
Karl Marx (Das Kapital, Volume One, 1867)
The wealth of those societies in which the capitalist mode of production
prevails, presents itself as ‘an immense accumulation of commodities,’
its unit being a single commodity. Our investigation must therefore
begin with the analysis of a commodity.”
On commodities and markets
• A commodity is a product of human labour
Since Aristotle we know that it has two essential properties (also Adam
Smith and Karl Marx)
• It has value in use
Things or activities/services are useful for somebody for some reason
• and value in exchange
Things or activities have a value for others. They pay a price for it in
the market.
• In the market individual values are compared to each other ->
market value is based on social necessary labor
competition the market creates a tendency
towards more efficiency
• If there is

• Assumptions:
• A) the basic socio-technical
structure is identical for all
S11 <>0
S12 <> 0
systems of feasible prices.
• B) The sum of the surplus prouct
is constant
• C) Sum of Prices = sum of values
S21 empty S22 empty
• Origin of price changes is a
different allocation of the surplus
product among branches of
production
• Values of commodities and
services are essentially different

General assumptions to determine labour values
• Each hour of labour has the same value
• The labour value of the output of a sector is
proportionate to directly and indirectly spent
average labor time = sum of past and actual labor
• The computation of the labor values are based on
the concept of equivalent exchange: the
enterprises receive for their commodities / services
the full amount of the labor they have used.
• The sum of values = sum of prices, therefore a
comparison of relative prices is possible
Consequences for services
• Enterprises who produce and sell services actually
appropriate parts of the surplus product without
contributing to it with their own production.
• In an economy in equilibrium commodity producing
sectors are therefore unable to realise the full value of
their product in the market – this means a violation of
the principle of equal exchange
• The only possibility for them to realise the full value is to
evaluate services under the condition of simple
reproduction – without appropriation of surplus product
• Therefore we have to evaluate the value of services at
reproduction cost
The labour of some of the most respectable orders in the society
is, like that of menial servants, unproductive of any value, and
does not fix or realize itself in any permanent subject; or vendible
commodity, which endures after that labour is past, and for which
an equal quantity of labour could afterwards be procured...…In
the same class must be ranked, some both of the gravest and
most important, and some of the most frivolous professions:
churchmen, lawyers, physicians, men of letters of all kinds;
players, buffoons, musicians, opera-singers, opera-dancers, &c.
…Like the declamation of the actor, the harangue of the orator,
or the tune of the musician, the work of all of them perishes in
the very instant of its production.

II, Chapter III, Of the Accumulation of Capital, or of Productive and Unproductive

Consequences
• The extension the services is ceteris paribus
connected with a lower accumulation rate in the
average, because the produced surplus product
will become relatively more scarce as the
advances of capital increase
• Eventually this could be an explanation of the
smaller growth rates in developed economies with
a high share of services.
• In addition to that there is also a self-strangulation
of effective demand by restrictive wage policy
Transformation problem
By Marx and von Bortkiewicz
Transformation problem
Transition from level 2 (labor values)
To level 3 (prices of production)
The physical parameters (primal problem) are not
changed by Marx
Captalism of perfect competition
Small commodity
production
Physical
basis
Prices of production, labor market
Labor values,
commodity and
services markets
use values,
materials, energy, ecologic dimension
Transformation problem can be seen as “experiment of
thought”
There are two different ideal types of economic systems
1. Small commodity production: producers work for their
own, without fixed capital, without wage labor. Prices will
finally become proportionate to labor values
2. Capitalistic Produktion: wage labor exists, capitalists
invest in sectors with higher rate of profit than their own.
Expectation by Marx: Rates of profit approach a general
rate of profit. Prices change to prices of production,
proportionate to capital advanced.
3. Quantities remain invariant by transformation
Transformation problem
• Marx explained the modification of values by competition of
capitalists
• He assumed that the movements come to an end if all the rates of
profit are equal.
• In a mathematical perspective he described the first step of an
iterative process – similar to Andrew Kliman’s Temporal Single
System Interpretation (TSSI).
• The repeated application of Marx’ method (but also of TSSI) leads to
the solution by von Bortkiewicz resp. to the Simultaneous Single
System Interpretation (SSSI) (i. e. input prices become equal to
output prices)
• One should not see SSSI and TSSI in Opposition, but as a process
which contains both moments.
Transformation problem: from labor values to prices of
production
Marx‘ solution
pp(0) = w or w* (classic or material labor values, in general: any starting
value can be chosen)
pp(1) = pp(0) R [1 + r(i)], R = A + C + D ... Matrix of reproduktion r(i) Profitrate
1 + r(i) = pp(i) x / [pp(i) R x],
i...counter for iteration
Problem: prices of input ≠ prices of output
von Bortkiewicz‘ solution
two identical solutions
a)
Eigenvector solution: pp ... left-Eigenvector of R
pp R (1 + r) = pp,
largest Eigenvector ofR: λ=1/(1+r)
b) iterative solution: i -> ∞
pp = pp(∞)
pp(i) = pp(i-1) R [1 + r(i-1)], 1 + r(i) = pp(i) x / [pp(i) R x]
Under the condition pp(i) x = const for all price systems =>
location of all prices vectors is a hyperplane in an ndimensional space.
Several Price Systems
• Prices observed:
P (Az + Cz + Sz) = P
• Classic labor values (all sectors produce value)
Pk = n (E-Az)-1
• „Material“ labor values (material production only produces
value)
Ps
• Prices of production with circulating capital only, equal rates of
profit)
Pzk
• Prices of production with fixed capital, equal rates of profit
Pfk
The different price systems are linked to different distributions of
the surplus product resp. surplus value.
The sum of the surplus product is always constant

Layer 3: prices of production, capitalist economy at perfect
competition („Transformation Problem“)
Marx provided us with the following solution for p:
p = v (K + A + C) (1 + r), where r = v (I - A - C) x / v (K + A + C) x
and v = l (I – A)-1
K…matrix of capital coefficients per unit of output, I …identity matrix with ones in
its main diagonal, otherwise zeros, and r is the average rate of profit.
This method can be generalized to an iteration process which leads us to the
solution proposed by von Bortkiewicz in the beginning of the 20th century (which
is equal to the solution of an eigenvector/eigenvalue problem). The generalized
iteration scheme inspired by Marx is:
pi (K + A + C) (1 + ri) = pi+1 where ri = pi (I - A - C) x / pi (K + A + C) x,
ri … average profit rate at iteration step i.
Different turnover times neglected, and assumed that they are all equal to one.
The link to labor time is kept up because the iteration scheme starts from the
solution of equation (3) for v
p0 = v = l (I – A)-1, where r0 = p0 (I - A - C) x / p0 (K + A + C) x
