An Introduction to Marxist Economics

This week's meeting was on the subject of Marxist economics. We had a very lively discussion afterwards, but here is, more or less, the speech that was given. Enjoy!


An introduction to Marxist economics



Marxist economics differs significantly from mainstream economics. Mainstream economics tends to focus on the amount of money people have. At first, this may seem like common sense. After all, the more money people have, the richer they are. A lot of mainstream economics tends to focus on things like deficits, surpluses, interest rates and inflation. All of this is about how much money there is about, who owns it and in the case of inflation, whether the amount of money you have will buy you the same things today as it did yesterday.
Mainstream economics is good at understanding how money moves and flows, grows and shrinks. Marxist economics is more interested in the driving factor that makes money worth something in the first place – value. In this talk I want to give a brief outline of Marx’s economic perspective, how it works in practise, and how Marxist economics informs our political perspective.


Marx and economics

Marxist economics is about value: how it is created in a capitalist society and what that means for social organisation. Marx did not get this idea from scratch. He was building on the work of earlier economists like Adam Smith and Ricardo, but with a few insights of his own. His theory did not spring into being fully-formed, but developed over the course of several decades. The most complete version is to be found in what is possibly his most famous work, Capital.

Volume I of Capital begins not with the working class, or the factory, or money. It begins with the commodity. The commodity is the heart of capitalism, its distinctive product, that which differentiates it from other forms of economic and social organisation. The commodity is any product created not for use but for trade. One criticism that is often heard when Marx’s theories are brought up in polite company is that of course Marx was all very well in his day but of course the system has changed now so it is no longer valid. And when you think about Marx’s starting point, of course they must be right. In Marx’s day commodities tended to be things like coats, but of course today none of us use such items. Commodities today are all services like Facebooks and suchlike.

Facetiousness aside, commodities are a really useful way of looking at capitalism. In every bottle of Coke we see the same process as in every TV, car and copy of GTA 5. It is the finished product of the system, and yet it is not produced because it is useful. Yes, every commodity satisfies some want or need, but that is not why it is made. It is made so that it can be sold. The sole purpose of production is to make a profit for the producer.

This is not the same as making money. Money is another kind of commodity. It is produced for exchange, just like a coat. The unique thing about it is that it is a universal form of exchange. All commodities are produced to be traded for something else, yet in capitalism we do not exchange coke for coats, but for the money commodity.


Value

So if everything is produced for exchange, what is being exchanged? When I buy my new 3D flatscreen TV for £1,000, what is it that makes my TV worth £1,000 – and more importantly, a thousand pounds of what?

This is where one of Marx’s key concepts comes in – value. What is embodied in every commodity made by capitalism is the one thing that all commodities have in common – human labour. When a worker sells their labour power to a capitalist, they do work on the production of commodities. It is this common feature which allows the commodities to be exchanged at all. If labour were not expended on them there would be nothing to exchange.

However, if exchanging £1,000 for a TV is really just an exchange of one item that embodies a certain amount of labour power for another, there would be no profit. If I exchange one orange for one orange, I have no more than I started with. Yet profit is at the heart of capitalism. It is the reason that businesses produce. Where does this profit come from?

The source of profit is the same as the source of exchange value: human labour power. It is also one of Marx’s key insights into the nature of economics. It is also very straightforward, once you think about the way businesses which you are familiar with actually work. One job I had once was working in a caravan handbrake factory. I was paid just over £5 an hour to work on a small production line for 7.5 hours a day. On the line we had to make hundreds of handbrakes per day between the four of us. Needless to say, the number of handbrakes we produced was worth far more to the company when sold on than it paid us in wages. This difference between the cost of human labour and the cost of the plant needed for us to produce the handbrakes is the profit that the company makes.

You may be thinking that the machinery is a source of profit – after all without it we could not have made any handbrakes at all, but it cannot be. No matter how much more efficient it makes the process of production, it cannot make more profit for the manufacturer. This comes down to the question of what is being exchanged when a commodity is bought and sold – a quantity of human labour power – and to what the machinery is really doing in the production process, which we will come onto shortly.

So the ability of the employer to pay their workers less than the value of the goods they produce is crucial to profit-making. Labour power is the source of value but by exchanging a lower value of the money commodity for each worker’s labour power than is congealed in the commodities they have created, an employer can profit. This is a necessarily exploitative relationship – and a worker can be well-paid and this will not affect the fundamental relationship between the employer and the worker. In fact a well-paid worker in a high-technology industry in the West can be more exploited in absolute terms than a sweatshop worker in Bangladesh in terms of their ability to generate more value from their work for their employer. Of course, this is not to make light of the poverty created by the system, but it does highlight one of the odder features of capitalism. It’s interesting that the very terminology adopted by capitalists unconsciously reflects this situation. In Engels’ book on the working class in England he reports how factory owners would refer to their workers as ‘hands’ – a term which accurately reflects what a worker means to an employer: not people, but a device for doing work.


Socially Necessary Labour Time

So what generates profits for an individual employer is the exploitation of the labour power that they purchase from their workers. But in capitalism all employers are in competition with others. If they are to survive, they must make more profits than their competitors or go bust. I will explain why shortly.

One way to do this is to lengthen the working day and decrease wages. Both of these make more profits by increasing the rate at which workers are exploited. Labour power is made cheaper but the number of commodities produced is higher so the profits of the capitalist rise. However, this cannot be extended indefinitely: workers need a certain minimum in order to survive, they physically can only work for so long. In addition, workers under sustained attack have a tendency to fight back – capitalists do not always get away with attacks on pay and conditions by employers. There is a limit to how much you can increase your profits this way.

This is where machinery comes in. Investing in new machinery can help make production more efficient and increase the amount of production. However, the machinery is purchased for an amount of money that reflects the labour congealed in it, just like any other commodity. Once purchased it is not a new source of value, but a way of extracting more value from the labour power of the workers involved in the production of the employer’s commodities. This is what Marx called ‘dead labour’, as opposed to the ‘living labour’ of workers.

However, the first employer to do this has a huge advantage over their competitors – with fewer workers they can produce more commodities and therefore make more profits when they sell them.

The reason that they can make more profits is that the money price of a commodity reflects the socially necessary labour time required to produce it. When the first manufacturer invests in new machinery, the price they can charge for their products is the same as the price of the old labour-intensive price that the rest of the industry is still using. However, all the manufacturers are in competition, so if they are not to go under they must invest in new machinery too. As everyone invests in the new machinery and the companies compete with each other, the money price they charge will drop to reflect the new lower labour time cost that is now socially necessary. This is a key difference between Marx’s understanding of economy and earlier thinkers like Smith.

This also shows one way in which the money price of a commodity does not directly reflect the amount of value created by the labour power congealed in it. The price, under normal conditions of capitalist production, is primarily affected by the socially necessary labour time required to produce the commodity – that is to say the average labour power used at average intensity in particular social conditions. However there are a range of other conditions in which the price of an object may differ significantly from the amount of labour invested in it. One major issue is crisis, which we will look at shortly.


The long-term tendency of the rate of profit to fall

What this shows about capitalism is its dynamism. It is constantly in motion, constantly changing. Nothing stays the same for long, and means of production are constantly being revolutionised as competing capitalists try to increase their profits. However, as you can see from the way that they have to increase their profits, there are limits to their ability to do this, and over time the rate of profit – the rate by which they can extract value from their workers – will fall as the socially necessary labour time for production falls. As the rate of profit falls, the profitability of the system as a whole falls. Capital accumulates – which is to say that there is more and more dead labour compared to living labour and it is harder and harder for capitalists to squeeze increased value from their workforce.

Crisis

The long-term tendency of the rate of profit to fall is at the heart of another key feature of the capitalist system: crisis. We are currently still in one of the longest crises in the history of capitalism, more than seven years after it began. Crisis has been a frequent visitor to the system, both as a whole and in its various parts. Mainstream economics often refers to crisis as ‘recession’ because it is interested in the growth of economies and thinks in terms of how much money is in them, so it sees recession as a setback on the path to growth. However, the real cause of crisis in the system is an accumulation. Because capitalists don’t extract profits just so that they can consume more, but so that they can create more profit, they reinvest a lot of the value that they extract in more production. This goes back into creating more commodities for sale and therefore more profit. Eventually, however, there comes a point where too much has been produced. Warehouses lie full of commodities that cannot be sold. Profit falls everywhere. Capitalists cannot just store up their profits indefinitely. Unless there are fresh profits being generated, the value of the money commodity will fall, as it only gains its apparent value through its use as a medium of exchange.

Meanwhile, as capitalists are unable to invest because they will not receive profits from their investments, workers are laid off because they are no longer generating profit. As workers are laid off or their pay is reduced, their consumption falls, leading to further and further reductions in profitability and still more workers losing their jobs. This is what happened in the great depression of the 1930s, and what we began to see again in 2007, as the financial crisis meant that workers, whose real wages have not increased since the early 1980s, were unable to secure further credit with which to maintain or increase levels of consumption. Demand and production fell and has not recovered fully to the levels reached before the crisis, which means that capitalists have yet to see a renewed increase in profits and investments are still low.


Destruction of capital

If crisis is a constant feature of the system, you would expect it to have collapsed long ago, but unfortunately it has not. The reason for this is that crisis destroys much of the accumulated capital that is clogging up the system. Unprofitable firms close down, its machinery is bought up by profitable parts of the system at a fraction of its value. The prices of unsold commodities fall. Workers’ conditions can be attacked more easily because of the higher unemployment, and profits begin to rise again as the cost of investment for the profitable parts of the system decrease (buying up cheap machinery from collapsed competitors) and more value is extracted from the workforce.

All of this means that capitalism goes through constant cycles of boom and bust, and must continue to do so. It also means that those who pay the cost of crises are the working class. Anyone who has seen the way in which austerity policies have been introduced can see this for themselves. The wealthy have continued to accumulate capital yet find few opportunities to reinvest it, and workers have paid through lower wages and reduced public services. Further, in the next crisis the managers of capitalism in the developed world will find it extremely difficult to resolve the crisis in the same way. Workers' living standards can only be cut so far without serious resistance, and capital can only sit idle for so long.


Fictitious Capital

Fictitious capital is basically finance capitalism. This is a system that runs alongside the productive processes of capitalism, that often supports capitalist production either through investment of the money commodity into production or the provision of credit to allow commodities to be purchased. Fundamentally it is an industry which deals in only one commodity – the money commodity, and has a huge influence on where that commodity goes and how much of it is manufactured. The current crisis within the capitalist system has its roots in the tendency of the system to seek new forms of profit – in this case by commodifying specific amounts of the money commodity into a series of transferable betting slips with names like Collateralised Debt Obligations and Credit Default Swaps. The interaction between the system of fictitious capital and the productive system is necessarily complex and headache-inducing, and probably deserves a talk all of its own.


Why socialism?

Our understanding of capitalist economy leads us to certain conclusions. Firstly, the working class are necessarily exploited by capitalist modes of production. Secondly, the working class is the class with the power to change the system.

By concentrating workers in large companies, workers understand their common interests and their ability to act together. Workers are the only source of profits for capitalists. By withholding their labour, workers can bring the system to a halt. This is why in the Socialist Workers’ Party we emphasise workers’ action over other forms of action. Direct action, demonstrations, protests can all have an impact, but only workers can stop the system. This is why 2 million people could march against the war, and yet it still went ahead. On the other hand, a general strike would have made war impossible to conduct.

Mainstream economists will tell you all about money. Marxist economics can teach us the value both of money and of the class of people that make it valuable.

Further Reading
This introduction is necessarily brief and glosses over much detailed analysis - much of which we were able to bring up in our discussion after the speech, especially on the nature of the financial crisis of the last 7 years. If you are interested in learning more about Marxist economics, one way is to come and meet us! Another way is to read some of these:

Bookmarks, the socialist bookshop also has a whole range of books on the subject of economics
Marx's oeuvre can be found online at the Marxists Internet Archive, but if attempting Capital itself, I would strongly recommend Marxist academic David Harvey's free accompanying lecture series and/or his book A Companion to Capital.
