The issue of what economic planning under socialism would look like was 
discussed at one of the panels at the 50th anniversary conference of the Union of 
Radical Political Economists (URPE), which was held at the end of September at 
the University of Massachusetts-Amherst. Seongjin Jeong put forward the view 
that money would be replaced by labor certificates, and that planning would be 
done according to the single measure of the labor hour.

I wasn't at the URPE conference; what I know about it is from a report written up 
by the left-wing economist Michael Roberts and placed on his blog, and from 
Jeong's draft paper "Soviet planning and the labor-time calculation model: 
implications for 21st-century socialism" which Roberts linked to. (1) In his paper, 
Jeong considers objections to his view, and as part of this, conscientiously refers 
to my three-part article "Labor-money and socialist planning", which puts forward 
a very different view. (http://www.communistvoice.org/00LaborHour.html) (2)

My article on socialist planning centered on showing that there was no single 
measure that could serve as the natural unit of socialist planning, not even the 
labor-hour, and that the use of the labor-hour as such a measure would result in 
duplicating many faults of capitalism. It traced the history of the idea of labor 
money in the socialist movement, and the repeated failures of the attempts to use 
labor money. It pointed out that the labor certificate under communism, as 
envisioned as a possibility by Marx, was only to be used for the distribution of 
consumer goods and not for overall economic planning nor for how workplaces 
would obtain the goods they needed for their operation. My article pointed to the 
development of methods to plan in material terms.

This might seem a rather obscure subject, but it bears on many practical matters. 
For example, the rationale for using market measures for environmental goals, 
rather than relying mainly on regulation and planning, lies in the belief that a 
single unit of measure is the way to achieve economic results. The rationale for 
reducing every decision to a calculation of profit and loss lies in the belief in a 
single unit of measure. And yet in reality it won't matter that much if money 
denominated in dollars or other national currency was replaced by calculation in 

Moreover, Jeong also claims that the Soviet planning agencies didn't really 
calculate properly or use input-output tables, and that this was a major cause of 
the shortages and disproportions in the Soviet economy.  According to Roberts, 
this line of reasoning led to the view that "with the development of AI [artificial 
intelligence], algorithms, big data and quantum power, such planning by labour 
time calculation is clearly feasible. Communism will work." In my view, such views 
slur over the fact that the problem with the Stalinist economy wasn't simply bad 
choices by Stalin and his successors, nor was it bad calculation due to the lack of 
computing power, but that the Soviet Union under Stalinism became a 
state-capitalist country with a new ruling class.

Given the importance of these issues, I would like to take this occasion to reply to 
Jeong's article, especially as Jeong focuses on several important points of 
economic analysis.

Jeong takes the labor-hour as the bottom-line of 
communist economic planning

Jeong holds that "The Marxian model of a communist economy, in its first phase, 
is characterized by 'planning based on labor-time calculation' (hereafter 
abbreviated as PLTC)."  And he writes that "PLTC is one of the essential 
components of Marx's communism." (3 - but from here on references to Jeong's 
paper will simply give the page number)

Now, in order to use the labor-hour in this way, it can't be measured by the labor 
of any one person --  it has to be labor of an average intensity. This is called the 
abstract labor hour, not in order to denigrate it, but to distinguish it from the 
concrete or definite labor hour exerted by a definite person at a definite time and 
location.  Jeong writes "...PLTC...is unthinkable if the unit of calculation is actual 
or individual labor-time. In the first phase of communism, where the economy of 
time to cope with the state of scarcity is still needed, PLTC is unavoidable, and its 
unit should be social." (p.82)

In this system, in order to ensure that every workplace has the necessary inputs, 
every product is measured in terms of the amount of the congealed labor-time 
embodied in it. So the PLTC means that one replaces the financial measure of 
the US dollar or the South Korean won with the abstract labor-hour. And just as 
financial calculation implies that two things with the same price are equal, the 
PLTC would imply that two things embodying the same amount of congealed 
labor-time are equal and interchangeable. (The congealed labor-time is what 
Jeong calls "the total labor-time embodied in products", p. 83)

But the PLTC can't handle environmental issues

Yet Jeong also admits that the PLTC has trouble with environmental issues. He 
says that "it is difficult for Marxian PLTC to take into consideration all the diversity 
of human life in an emancipated communist society or ecological issues." (p. 84)

Nor is Jeong the only advocate of the PLTC who admits that it can't deal with 
environmental issues. Allin Cottrell and W. Paul Cockshott are passionate 
advocates of using labor-time as the socialist economic measure. And yet they 
say that "We are not claiming that labor-time calculation would necessarily do 
better [than capitalism] in cases where the market fails to conserve resources. ... 
We have no problem with the idea that environmental considerations and 
labour-time accounting are not necessarily reducible to a scalar common 
denominator, and that the balancing of these considerations may require political 
judgment on which opinions can differ." (4)

I discussed this in my article on socialist planning. (5) Indeed, in my view PLTC 
would have trouble with other issues as well, including health care, education, 
and child care. There would have to be one correction to PLTC after another to 
allow sufficient attention to be paid to them. Oops. So much for planning with a 
single measure.

For Jeong, these problems are simply shortcomings of the PLTC, which show that 
it won't be used at a later stage of communism. He says that such "qualifications 
should not be considered a rejection of PLTC. Far from being incongruent with 
the developed phase of communism, PLTC is indispensable to the advance of 
communism to its developed phase." (p. 84)

But how can PLTC be a useful economic phase in the 21st century if it doesn't 
deal with the pressing environmental issues? How can production be organized 
properly without protecting the environment, and without considering such other 
issues as the proper support for social programs, issues that PTLC doesn't deal 
with? It's a farce to talk about "21st century socialism", which is faced with global 
warming, rampant pollution, and other problems, and put forward a planning 
system which can't deal with them. And it's a farce to say one has a single unit of 
measure, if one has to made one correction after another in the calculations with 
that unit.

Jeong even says "Just replacing a market price-based coordination by a 
labor-time calculation is not sufficient to free the system from the law of value." (p. 
83) And he goes on to say that "the Marxian communist model of PLTC is 
inherently contradictory, in that it tends to virtually simulate and reproduce the 
capitalist labor-value system." (p. 84) I strongly agree that replacing financial 
calculation with labor-hour calculation tends to reproduce capitalist exchange.

But I disagree that it's Marx's model. On the contrary, Marx put forward the labor 
theory of value to show how capitalism operates and how workers are exploited, 
not to show how to plan socialist production. I will come back to Marx's view about 
what's wrong with labor time calculation in a moment. But first let's see why Jeong 
insists on it as the bottom line of economic calculation.

Is reducing things to a single unit of measure
necessary for economic calculation?

Jeong adheres to the PLTC because he believes that rational economic planning 
requires "using a single unit of measure". He writes that "it is impossible to 
achieve macroeconomic coordination and balance without adopting a single unit 
of measure that enables the calculation of social averages. ... Planning without 
this single accounting unit is simply a contradiction in terms, tantamount to the 
rejection of planning altogether." (p. 81)

Using a single unit of measure means that this unit is the bottom line of 
calculation - everything is measured or valued in accordance with this unit. This is 
what is done in capitalist society with money, where the dollar reigns supreme in 
the US. And then the best alternative is supposedly that which gives the most 
profit, or which come out highest in a cost-benefit comparison. It is because we 
are so used to it from everyday market experience that this seems utterly natural 
to us. Jeong's picture of the early phase of communism preserves this use of a 
single measure by replacing money with labor certificates based on labor hours, 
but he recognizes, as we have seen, that having such a single unit "tends to 
virtually simulate and reproduce the capitalist labor-value system".

But what is the alternative? Is there a way to carry out economic planning without 
relying on a single unit as the bottom line? Well, first let's see that Marx showed 
that no single unit would suffice, and then see whether alternative methods of 
calculation and planning have ever been used in modern industrial economies.

Marx vs. the single unit of measure

Jeong cites a passage from Marx's "Grundrisse" to back up his claim that a single 
unit of economic measurement is needed, and that this unit is the labor hour. But 
when we look a little closer at the passage, it turns out that Marx was actually in 
the midst of reiterating one of his main theoretical arguments against the use of a 
single unit of measurement.

Marx wrote: "On the basis of communal production, the determination of time 
remains, of course, essential. ... Economy of time, to this all economy ultimately 
reduces itself. ... Thus, economy of time, along with the planned distribution of 
labor time among the various branches of production, remains the first economic 
law on the basis of the communal production. However, this is essentially 
different from a measurement of exchange values (labor or products) by labor 
time." (6)

By itself, this looks like Marx was emphasizing the use of a single unit, the labor 
time. The problem, however, is that Jeong left out the rest of the paragraph, 
which deals with one of the ways in which the treatment of labor time in 
communal society will differ from that of capitalist society. Marx wrote:

"The labour of individuals in the same branch of work, and the various kinds of 
work, are different from one another not only quantitatively but also qualitatively. 
What does a solely quantitative difference between things presuppose? The 
identity of their qualities. Hence, the quantitative measure of labours presupposes 
the equivalence, the identity of their quality." (emphasis as in the original)

This is a contrast of abstract and concrete labor. The abstract labor hour only 
measures labor quantitatively, while concrete labor has definite properties, which 
are important. Equating things quantitatively, or comparing them only 
quantitatively, means ignoring the qualitative differences between them.

This is a major theme which he returned to repeatedly in the "Grundrisse" and, for 
that matter, in "Capital". Clearly Marx's idea was that future society will need to 
take account of the qualitative differences, something which no single measure, 
neither money nor measurement by the abstract labor hour, can accomplish. One 
can't deal seriously with Marx's standpoint about economic planning without 
taking this into account. At the same time, what's true or not doesn't depend 
simply on textual analysis. Marx's standpoint and writings deserve close study, 
but what he said about qualitative differences is correct, not because he said it, 
but because it corresponds to economic reality.

For example, if labor time were the single unit of measure, then one hour of a 
carpenter's labor would equal one hour of a welders' labor.  Marx is saying no, 
they are qualitatively different. For example, if we need so many carpenters, we 
cannot replace them by so many welders. The carpenter and the welder might be 
paid the same, but if we are to ensure that construction can take place, we need 
to keep track of carpenters and welders separately.

The same thing holds when one compares two different products or material 
goods. One labor hour's worth of one material good is not qualitatively equal to 
one labor hour's worth of a different good. For example, economic planning 
needs to keep track separately of such things as how much food there is, and 
how much steel. Food that took one hour of labor time to produce (counting both 
direct and indirect labor) isn't the same thing as, say, steel that took one hour to 
produce. With respect to the abstract labor hour, one hour = one hour = one hour. 
With respect to money, one dollar = one dollar = one dollar. But with respect to 
rational economic planning, they're different. We can't eat steel. We can't use 
food to build bridges and buildings. So the amount of food and steel available has 
to be calculated separately. Thus, effective planning for a project cannot leave it 
at there are supplies available worth, say, a million labor hours, but has to break 
down what is needed into different categories. So, while Jeong claims that 
economic calculation absolutely requires using a "single unit of measure", the 
opposite is true.

In the quote from "Grundrisse", Marx was saying that economic calculation is 
always necessary, even under communism (we shall see later on that Jeong 
doesn't believe this is so in later-phase communism), but it cannot be done with 
the single measure.

As we have seen, Jeong himself recognizes that PLTC has difficulty accounting 
for qualitative diversity and environmental issues. But he doesn't realize why this 
is so. Effective calculation must take account of the abstract labor hour, but it 
must also deal with other factors of economic importance. It must not reduce 
matters to a single factor.

Calculation with many units of measure

Still, thanks to living in a capitalist society and having to buy and sell things all the 
time, it might seem to be only common sense that calculation requires a single 
unit of measure.  This might seem particularly so if, as is probably only too 
common, one wasn't taught the spirit of mathematics in school, but only one 
mechanical rule of calculation after another. But during the last century methods 
were developed to plan in physical terms. They were used by governments of 
vastly different types, not just the Soviet Union but to some extent by Western 
capitalist countries and also some newly-independent countries. This type of 
planning didn't just take into consideration the overall size of the economy, or the 
Gross Domestic Product. Nor did it simply list the different types of material goods 
that existed. It paid attention to the "intersectoral flows" that connected one 
branch of the economy with the other. Steel, for example, wouldn't be measured 
simply by how much it cost, nor by the total labor-hours needed to produce it. 
Instead steel would be measured by the resources that were needed from each 
other sector of the economy for the production of steel, while the other sectors of 
the economy were measured, in part, by how much steel they needed for their 

This new type of calculation was first put forward in the Soviet Union in the 1920s, 
and was called "material balances". The method used to adjust these material 
balances was mathematically crude, but was an important new departure in 
planning. It seems to have helped inspire the development of input-output tables 
in Western capitalist countries, which were also taken up to some extent in the 
Soviet Union. In parts one and two of my article on the "labor hour and socialist 
planning" I explain the basic idea behind these methods in more detail, and I also 
show that Marx foreshadowed these methods in volume II of "Capital" where he 
wrote equations connecting how different sectors of a capitalist economy interact 
with each other.

These methods of physical planning were not communist planning, and as 
mentioned, were used by governments of all types. But they did show that it is 
possible to calculate using multiple units of measure, and that it was absolutely 
necessary to do so to achieve realistic results. That's why even diehard capitalist 
governments make a certain use of them, albeit only as an occasional 
supplement to overall financial planning. So these methods did not achieve, or in 
most cases even aim at, a fully planned economy, but they showed that some 
physical planning was needed even for very limited goals.

Jeong holds that I champion the way the Soviet Union prepared material 
balances as against input-output tables. But in my article, I wrote that the  
"Western input-output methods...are essentially a variant of the method of 
material balances. Input-output methods start ... from the point of working with 
balances of goods regarded as qualitatively different. ... Western economic 
authors like to make various fine distinctions between material balances, 
input-output methods, and linear programming. ... [But these distinctions] don't 
affect the issue raised in this article. What is important, is that all these methods 
use a multitude of separate balances of qualitatively distinct goods." (7) So I 
sometimes grouped all these methods, including the "Soviet version of material 
balances", under the general term "material balances". I stressed that  the various 
forms of material balances were not socialist planning, and all that they had "in 
common with the future economic calculation of a classless society, is that they 
both have to keep track of society's production in material terms." (8)

The use of material balances does not prove
an economic system is socialist

Jeong seeks to discredit the idea of material balances because it means 
abandoning the single unit. He promotes input-output tables, because he believes 
this means using a single measure.

To do so, he  writes "It is ... not correct to regard material balances as a 
specifically communist method of resource allocation. Even in capitalism, variants 
of material balances have been frequently used to allocate some strategically 
crucial goods when the monetary economy does not work, like during wartime." 
(p. 81) I agree strongly with him on this, and I repeatedly made the same point, 
right up to the use of the same example of wartime planning, in my article on 
socialist planning.

But the same points also apply to input-output tables and linear programming. 
They are only technical planning tools, while socialism is based on whether the 
working class owns and directs the economy. It's the social structure of a country, 
the class regulations, that define socialism, not the planning tools. And socialist 
planning involves planning from below as well as above. Without a socialist 
structure, no matter how much planning is attempted, only a limited amount can 
be achieved.

For that matter, in my article on socialist planning I pointed out that material 
balances and input-output tables aren't even the last word in physical planning. 
For example, these methods depend on certain assumptions about the economy, 
which are only approximately true (such as that twice as much production always 
requires exactly twice as much resources). Environmental issues could be 
included in the calculations but generally aren't. And so forth. These methods are 
but a step in the direction of realistic physical planning. They have in common 
with future communist planning that they make use of not one, but many separate 
natural units.

Input-output tables may or may not be material planning

Jeong writes in praise of input-output tables that "input-output tables can be 
compiled in terms of physical natural units as well as monetary or labor-time 
ones". (p. 81) And this is true. But what Jeong misses is that when input-output 
tables are written in terms of many physical natural units, then they are being 
used as material balances, whereas otherwise they might not be. There is a 
subtlety here. The difference isn't simply whether the table has entries written in 
financial terms. It's whether the table attempts to combine categories which are 
qualitatively different into a single combined or aggregate category (for example, 
combining the quantity of food and that of steel into a combined category which 
embraces both). This is explained in more detail in my article on socialist 
planning, which also refers to how this distinction was drawn by the late Wassily 
Leontief, the bourgeois economist who was the father of Western input-output 
analysis. (9)

The point here is that when input-output tables represent material planning, they 
are an example of calculations that go beyond using a single unit of measure. 
When, instead, they use a single unit of measure, whether the dollar or the 
labor-hour, to combine entries with qualitatively different properties, they have 
what Leontief very politely called "a faint but unmistakable air of unreality". (10)

The supposed abolition of labor and economic planning

Jeong insists that the PLTC is indispensable in the early stage of communism, 
but says it will vanish in developed communism. That is how he reconciles his 
recognition that using the abstract labor-hour as the single unit will be similar to 
"the capitalist labor-value system" with his picture of communism. (p. 84) He 
holds that PLTC will lead to economic advances that will lay the basis for the 
advanced phase of communism that will do without the PLTC.

But wait a minute! If economic calculation is supposed to require a single unit of 
calculation, namely the abstract labor hour of the PLTC, how can economic 
calculation be carried out in advanced communism without the PLTC? Apparently 
Jeong believes that there will be no economic calculation in advanced 
communism. This is utterly astonishing, but that is where his argument leads.

Moreover, he writes that "labor will ... be transformed into activities", and that "the 
essence of Marxian communism is not the domination of labor but its abolition." 
(p. 84) True, Marx envisioned in his "Critique of the Gotha Program" that labor will 
change from something workers have to do into "life's prime want". But Jeong 
goes further, and describes this as the abolition of labor. And, of course, if labor is 
abolished, then it follows that labor-time vanishes too. But according to Jeong's 
system, with the lack of that single unit of measurement, the abstract labor-hour, 
"macroeconomic coordination and balance" is impossible to achieve, and there 
would be "the rejection of planning altogether."

Now, Marx too thought that labor certificates would vanish as communism 
developed. Jeong writes about "needs-based distribution" and pays attention to 
how from the start of communism some of the social product will be distributed 
freely. (pp. 83-84) This is in accordance with Marx. But Jeong then identifies how 
much economic planning takes place with how many labor certificates are 
circulating. This means to forget about the planning that is necessary in order to 
produce the goods. Marx, on the contrary, distinguished between how goods are 
distributed, and whether there had to be economic planning.

After all, where do the necessities and luxuries of life come from? From where do 
all the good things come that are distributed among people, and how does one 
ensure that production is carried out in a way that protects the environment? This 
requires planning. Marx stressed repeatedly that economic planning wouldn't 
vanish in communism, but simply take on another form. Recall that Jeong himself, 
when arguing for the single economic measure, cites a passage in which Marx 
says that "the planned distribution of labour time among the various branches of 
production remains the first economic law" of communist production. Indeed, 
Marx wrote that such planning "becomes law, to an even higher degree" than 
existed under capitalism. Nowhere does Marx suggest or even hint that this 
planning will diminish as communism develops.

It is not Marx, but Jeong, who first assumes that the economic planning must be 
carried out in a way similar to that of "the capitalist labor-value system", and then 
concludes that therefore, to avoid the capitalist labor-value system, there must be 
an end to labor and calculation itself.

While I disagree with many things that Jeong puts forward, I think he has done a 
service by putting them forward and looking into the contradictions in them. If I 
have time, I will take up the issue of what went wrong with the Soviet economy in 
a continuation of this reply.
