Everything about Value Product totally explained
The
value product (VP) is an economic concept formulated by
Karl Marx in his critique of
political economy during the 1860s, and used in Marxian social accounting theory for
capitalist economies. Its annual monetary value is approximately equal to the netted sum of six
flows of income generated by production:
- wages & salaries.
- profit.
- interest.
- rent paid by producing enterprises from current gross income, including land rents.
- tax on production.
- fees paid by producing enterprises from current gross income, including royalty fees, certain honorariums and corporate officers' fees, and certain leasing fees incurred in production and paid from current gross income.
The last five money-incomes are components of realised
surplus value. In principle, the value product also includes unsold inventories of new outputs.
Definition
The concept is formulated more precisely when Marx considers the reproduction and distribution of the national income (see for example his manuscript called "Results of the Immediate [orDirect] Process of Production", available in English in the Pelican edition of
Das Kapital), and also online; and the last chapters of
Das Kapital Volume 3).
Marx wrote this in 1864, for example about 70 years or so before the first comprehensive
Gross National Product and
Capital Formation statistics were pioneered by the likes of
Wassily Leontief,
Simon Kuznets and
Colin Clark (the
United Nations standard accounting system was first finalised in 1953). Marx's manuscript for
Das Kapital Vol. 3 ends with a discussion of "relations of distribution", but he didn't live to complete his analysis. In outline his approach is quite clear however.
Marx called
Gross Output (or the total value of output sales) the "
value of production" ("VPn").
If
variable capital paid
, circulating
constant capital consumed
,
fixed capital consumed
, and
surplus value produced
, then:
» Gross Output
and
» true new value added
So, Marx's "value product" really expressed his view of the true total
new value added or the net product. In his view, this total is equal to the value of wage payments +
surplus value, the latter which would include, apart from net profit, interest and rent, the net tax levy and royalty-type fees paid in respect of incomes generated by production of output, plus the surplus-value component of unsold inventories of new output. Marx himself never discussed taxation and royalty-income in detail; they were only a small portion of the total national income when he lived (around 5-10% or so).
An additional comment by Marx
Marx claims that, in an accounting period, the workforce in the capitalist sector normally produces a new value which is equal to its own wage-cost, plus an additional new value (called
surplus value).
However, Marx warns that:
"The habit of representing surplus-value and value of labor-power as fractions of the value created — a habit that originates in the capitalist mode of production itself, and whose import will hereafter be disclosed — conceals the very transaction that characterizes capital, namely the exchange of variable capital for living labor-power, and the consequent exclusion of the laborer from the product. Instead of the real fact, we've false semblance of an association, in which laborer and capitalist divide the product in proportion to the different elements which they respectively contribute towards its formation."

For this reason, Marx criticized ratios such as the
share of profits and wages (
wage share) in the gross or net product as deceptive, because they disguised the real capitalist
relations of production, specifically the rate of
surplus value. His primary interest was in the ratio between generic profits and wages (the
rate of exploitation).
Marxian new value added, versus GDP
The equation of new
value added with net output or
GDP (also known as gross value added) would have made no sense to Marx, mainly because net output
includes depreciation (or the
consumption of fixed capital), yet
excludes various property rents paid by producing enterprises from their gross income (on the ground that renting out an asset doesn't itself constitute production) as well as a portion of net interest (regarded as property income).
As regards depreciation, for Marx the value of
real depreciation at least didn't constitute any
new value, but, value
conserved and
transferred to the new products by living labor. It appeared as
added value, only because when
costs are deducted from gross sales income to obtain net
profit, depreciation is regarded as a component of the new
gross profit income. In official national accounts, a distinction is made between gross value added (including depreciation charges) and net value added (excluding them).
Of course, in reality it could be that real ("economic") depreciation diverges from depreciation for tax purposes. In that case, the reported
consumption of fixed capital could contain an element of undistributed profit. Additionally, official national accounts may include in consumption of fixed capital the value of those
insurance premiums, interest and rents paid from gross income, which relate directly to the acquisition or maintenance of productive fixed assets, on the ground that they're part of the cost of operating productive fixed assets. In
Marxian economics, however, these flows would be regarded either as a
faux frais of production, a circulating
constant capital outlay, or an element of gross
surplus value.
By contrast, Marx considered rents paid by producing enterprises from their gross income as a part of surp-lus value, and as an integral part of the cost structure of the social product. Business rents, excluded as intermediate expenditures from GDP, therefore are included in the Marxian value product as a component of surplus value.
From a Marxian point of view, official
value added also includes some dubious components such as the rental value of owner-occupied housing. This entry is the market rent of owner-occupied housing that would apply
if the housing was rented, treated as a "service". But most of it doesn't refer to any real flow of income, nor is it clear that this component has anything to do with production.
As regards net interest, the official product accounts will exclude a portion of it, insofar as it's defined as
property income unrelated to the value of production. But if it's paid from current gross revenues of producing enterprises, then it should be included in the Marxian value product. For this reason, the Marxian net interest aggregate is likely to be larger than the official one.
Criticism & controversy
Marx's idea of value creation and value product makes little sense from the point of view of the theory of
factors of production and
production functions.
Marx himself already anticipated this, in chapter 48 of Capital Vol. 3, titled "The Trinity Formula" where he discusses the view that land, labour and capital (which he sarcastically calls the "holy trinity" of political economy) all contribute to the creation of new value (Marx regarded human labour and land as the mainsprings of material wealth, but he considered
value as a purely
social attribution referring to labor-content). In modern
macroeconomics, the controversy surfaces again, and is discussed in amusing essays by Prof. Anwar Shaikh (see references).
In Marxian social accounting, one theoretical controversy concerns the treatment of the wages of so-called
productive and unproductive labour.
Unproductive labour by definition doesn't make net additions to the new value product, but only
transfers value from other sectors. Depending on how the gross and net product are defined, the value of these wages could be accounted for either as a component of
surplus value, or as a circulating
constant capital outlay, or be
excluded from the value product altogether.
Different interpretations are offered by Shane Mage, Murray Smith, Anwar Shaikh and Fred Moseley. One aspect often overlooked in this controversy is that wages costs and labour costs are not the same thing. Employers and employees must also pay social insurance levies of various types, and there may be other imposts on wages; also, the
buying power of wages is reduced by indirect tax imposts and profit imposts. This affects the magnitude of a society's variable capital and the value of labour power.
Another Marxian accounting controversy, less discussed, concerns which net tax receipts of government constitute part of the new value product.
Obviously taxes included in official gross product measures don't equal the net total tax take, because some taxes are unrelated to production and therefore excluded. The Marxian critique of
public finance appears to be rather undeveloped as yet, however. In principle, net tax levied on current production and paid out of current gross revenues would be included in the value product.
Least discussed is the problem of finding a non-arbitrary, rigorous distinction between value created and value transferred in respect of services. The conceptual problem here's essentially that it may be difficult to specify unambiguously what the nature and function of the "product" sold is, when services are rendered.
Some Marxists have argued however that Marx's value relations and value aggregates can't be measured at all, and at best only experienced. That was manifestly not Marx's view; already in his
Grundrisse manuscript he'd referred to a balance sheet cited by
Malthus; in
Das Kapital he attempted to calculate the rate of surplus value according to data provided by
Frederick Engels; and towards the end of his life, as Leontief noted, he wrote that he wanted to study the "ups and downs" of economic activity mathematically (but Samuel Moore convinced him that the data to do it didn't exist yet). Engels later remarked that the problem really was that much data relevant to testing Marx's concepts simply wasn't available.
The difference between Marx and naïve
empiricists was essentially that Marx didn't believe in conflating real economic relations with the
data that represented those relations. At best, useful statistical
indicators could be constructed to verify the observable trends. Yet, if this wasn't done, one was left only with hypotheses and speculations.
Subsequent Marxian scholars have argued the critique of political economy should continue, with regard to the new economic concepts and theories, rather than stop at the point where the ink dried on the last sheet of paper that Marx wrote on. One reason is that the new concepts and theories might distort the representation of economic reality, just as much as the old ones that Marx criticized.
In the
USSR and other Soviet-type societies, Marx's social accounting approach strongly influenced the
Material Product System (MPS), a social accounting method alternative to GDP accounts, which distinguished sharply between "productive" and "non-productive" sectors of the economy. These accounts focused on balances of the value of material goods produced. In some respects, this is ironic, since Marx's social accounting referred to the capitalist economy, not to a socialist economy. The MPS accounts were abandoned in favour of GDP accounts after the downfall of official communism in the USSR and Eastern Europe.
