Yeah I’ve also heard of academics who call themselves ‘Marxians’ to mean while they study and apply Marxist economics, they don’t want the label of political Marxism.

Labour is what gives something value, but not all labour is of value (see: Keir Starmer)

It’s odd that Marx was inspired by liberal economists, yet the ones we see today are the caricatures of capitalists we see in old timey propaganda

I wish I had notes written up into some type of primer as a few people have asked for a similar introduction to Sraffa or Ian Wright’s work and I never know exactly what to say. I never found one good introduction, and I’ve had to pick this up from various sources. Note that there is still much I need to learn and blind spots I may have, but here are a set of sources that may be useful for anyone wishing to understand Sraffa, Pasinetti, or Ian Wright’s solution to the transformation problem.

First, much of this relies on knowledge of linear algebra. Any introduction to vectors and matrices can suffice - you don’t need an advanced knowledge of linear algebra. Feel comfortable with vector multiplication with matrices (for left/row and right/column vectors), inverse matrices, and eigenvalues. I know that a hexbear user here lately joked that they get nothing from math videos, but if you do want to refresh your knowledge of intuition of linear algebra then I suggest checking out 3Blue1Brown’s video series on the topic. Personally, I enjoyed how they made the topic visual, and it helped me better understand topics in the field that I only ‘formally’ knew. There’s also Khan academy and many other intros to Lin. Alg.

If you want to jump directly into Ian Wright’s arguments then you could check out his paper Marx’s Transformation Problem and Pasinetti’s Vertically Integrated Subsystems (2019). This is his correction to Pasinetti’s earlier work Growing Subsystems, vertically Hyper-Integrated Sectors and the Labour Theory of Value (1988). These aren’t introductions, though.

As I mentioned earlier, I don’t have a single great introductory work to give you. If others know of one, I’d be happy to check it out! But, one can start by learning Input Output tables. These tables as we know them today were introduced by Wassily Leontief, and though I don’t have a work for introducing Leontief’s Input Output table one can find plenty of sources on this online. Even Wikipedia is not too bad of a place for a basic introduction to them. When you learn how Input Output tables are used then you understand the “quantity equation” in Sraffa’s model. This tells you how much of each product/commodity should be produced overall given some net demand. Sraffa’s model introduces a “price equation” using Input Output analysis that breaks price into wages, costs of materials, and profits. The simplest version of his model ignores fixed capital and assumes purely circulating capital (there are different attempts at how to generalize this to fixed capital).

A tangent on equilibrium before moving on: Some people will criticize Input Output analysis as it assumes equilibrium. While I think it’s obviously important to note that disequilibrium is the norm I sometimes feel those critiques miss the point of Input Output analysis. If one is familiar with dynamic systems then one is likely aware of attractors. These are points or states in some “space” (real space, “economic” space, etc.) which a system tends to evolve toward (or maybe ‘hover’ around). Attractors can tell you something about the structure or behavior of a system even if the system is never at the attractor. I like to think of equilibrium points analyzed in Input Output models as an analysis of this attractor (which can also grow or change with time) in an economic system. The economy may be in disequilibrium at any given time, but its long term behavior, or the direction the system is evolving toward at a given time can be understood by modeling this attractor. Shaikh also discusses this interpretation of equilibrium analysis in his book Capitalism: Competition, Crisis, and Conflict and discusses it as turbulent gravitation and claims this is a view of equilibrium that Classical economists also had. This view of equilibrium in Leontief’s/Sraffa’s models is a view Wright shares as well. Effectively an input output analysis tells us something about the structure of an economy, even if the economy is not in equilibrium at any given moment. Others may disagree, and I’m definitely not an expert - I’m coming at this from a different background than economics. So keep that in mind.

For works on Sraffa, there is his own piece Production of Commodities by Means of Commodites (1960), but the linear algebra notation is not “up-to-date” which can make it harder to read. There is also Passinetti’s Lectures on the Theory of Production (1977) which is a good intro to Leontief and Sraffa and has a good appendix for Linear Algebra, but is likely hard to get a copy of. Another work is Kurz and Salvadori’s Theory of Production. A Long-Period Analysis (1995), though I haven’t given this a read. These works will accept that the labor theory of value is incomplete or incorrect, though. So this is why I recommend “completing” them with Ian Wright’s work if you accept it.

Honestly, though, I started with multiple places. I didn’t start with the above books. One of the first papers I read about this is Ian Wright’s Nonstandard Labour Values (2007). This can be a good place to start once you have a handle on linear algebra as the work is available online. Another is Ian Wright’s own thesis The Law of Value (2015) which you can find online as well. Something I like about how Ian Wright approaches this field is that he uses network diagrams to show the flow of products, labor, and capital. Coming from a Physics field I like some type of diagram to go with any math and description of a system - so that helped me. If you want a non-mathematical argument for Wright’s solution then you can check out Chapter 3 of his thesis. Chapter 7 is his attempt at moving away from static models and toward a dynamic model of the labor theory of value.

Wright also has a blog, Dark Marxism and the earlier pieces provide an introduction to Input Output analysis so you may find that useful as well. In this blog he introduces Pasinetti’s idea of a self-replacing subsystem (i.e. a vertically integrated subsystem) which is another way of approaching an Input Output table.

Wright also has some interesting takes bringing esoteric thought to Marxism, viewing Capital as a egregore or a demon or demiurgic-like entity. So those can be refreshing when you want to take a break from the math. I’ve seen others here on Hexbear link or reference those parts of his work. Politically he seems like a Trot (sad), though I like his writings.

I probably sound like I’m his alt-account or something, so I do apologize for focusing so much on what he has written. But I have learned a lot from reading his papers and I’m still new to the field as well. I do think a solution to the transformation problem is important for Marx’s standing as a science because even here on this post we can see people debating the truth behind the labor theory of value. I see the transformation problem as introducing a crisis of confidence in Marx’s political economy (for some more than others) and so there is importance in resolving it. In relation to profits, the importance of the labor theory of value is these profits, the source of “income” for the capitalists can be shown directly to be the exploited labor of the workers. There is no justification via utility theory or other stances. And political economy can and should be studied from this viewpoint of labor. Exploitation is not some subjective ill (which would be bad enough if it were) but has an objective existence as the pillaging of the real time, energy, and spirit of the working class. Profits are directly related to the amount of this labor that the ruling class steals from us. And a solution to the transformation problem restores our confidence in formally stating this. Hope this was of some help!
