23 Things They Don't Tell You About Capitalism

One cause of genuine de-industrialization has recently attracted a lot of attention. It is the rise of manufacturing imports from low-cost developing countries, especially China. However dramatic it may look, it is not the main explanation for de-industrialization in the rich countries. China’s exports did not make a real impact until the late 1990s, but the de-industrialization process had already started in the 1970s in most rich countries. Most estimates show that the rise of China as the new workshop of the world can explain only around 20 per cent of de-industrialization in the rich countries that has happened so far.

Many people think that the remaining 80 per cent or so can be largely explained by the natural tendency of the (relative) demand for manufactured goods to fall with rising prosperity. However, a closer look reveals that this demand effect is actually very small. It looks as if we are spending ever higher shares of our income on services not because we are consuming ever more services in absolute terms but mainly because services are becoming ever more expensive in relative terms.

With the (inflation-adjusted) amount of money you paid to get a PC ten years ago, today you can probably buy three, if not four, computers of equal or even greater computing power (and certainly smaller size). As a result, you probably have two, rather than just one, computers. But, even with two computers, the portion of your income that you spend on computers has gone down quite a lot (for the sake of argument, I am assuming that your income, after adjusting for inflation, is the same). In contrast, you are probably getting the same number of haircuts as you did ten years ago (if you haven’t gone thin on top, that is). The price of haircuts has probably gone up somewhat, so the proportion of your income that goes to your haircuts is greater than it was ten years ago. The result is that it looks as if you are spending a greater (smaller) portion of your income on haircuts (computers) than before, but the reality is that you are actually consuming more computers than before, while your consumption of haircuts is the same.

Indeed, if you adjust for the changes in relative prices (or, to use technical jargon, if you measure things in constantprices), the decline of manufacturing in the rich countries has been far less steep than it appears to be. For example, in the case of Britain, the share of manufacturing in total output, without counting the relative price effects (to use the jargon, in currentprices), fell by over40 per cent between 1955 and 1990 (from 37 per cent to 21 per cent). However, when taking the relative price effects into account, the fall was only by just over 10 per cent (from 27 per cent to 24 per cent).[3] In other words, the realdemand effect – that is the demand effect after taking relative price changes into account – is small.

Then why are the relative prices of manufactured goods falling? It is because manufacturing industries tend to have faster productivity growth than services. As the output of the manufacturing sector increases faster than the output of the service sector, the prices of the manufactured goods relative to those of services fall. In manufacturing, where mechanization and the use of chemical processes are much easier, it is easier to raise productivity than in services. In contrast, by their very nature, many service activities are inherently impervious to productivity increase without diluting the quality of the product.

In some cases, the very attempt to increase productivity will destroy the product itself. If a string quartet trots through a twenty-seven-minute piece in nine minutes, would you say that its productivity has trebled?

For some other services, the apparent higher productivity is due to the debasement of the product. A teacher can raise her apparent productivity by four times by having four times as many pupils in her classroom, but the quality of her ‘product’ has been diluted by the fact that she cannot pay as much individual attention as before. A lot of the increases in retail service productivity in countries such as the US and Britain has been bought by lowering the quality of the retail service itself while ostensibly offering cheaper shoes, sofas and apples: there are fewer sales assistants at shoe stores, so you wait twenty minutes instead of five; you have to wait four weeks, rather than two, for the delivery of your new sofa and probably also have to take a day off work because they will only deliver ‘sometime between 8 a.m. and 6 p.m.’; you spend much more time than before driving to the new supermarket and walking through the now longer aisles when you get there, because those apples are cheaper than in the old supermarket only because the new supermarket is in the middle of nowhere and thus can have more floor space.
