I know I have been writing too much lately regarding China’s economy and I know that much of what I have written has been negative. But I have to tell you that I am starting to see all sorts of fissures breaking out in China’s economy and they are scaring the hell out of me. I am not writing to jump on any bandwagon (as one e-mailer accused me) but because I am really worried.
I am worried not just from what I am seeing, but because the real economists out there (not the people who claim to be economists just because they live in China) are also saying some pretty scary things. One of those real economists, Michael Pettis, just came out with what I see as a brilliant piece on how China has overinvested in capital and how its capital investments have been misallocated. It is entitled, “How do we know that China is overinvesting” and I strongly urge you to read the whole thing.
I love Pettis’s piece for three reasons. One, I have never bought into the idea that a bunch of geniuses sitting in Beijing are betting at allocating funds than the invisible hand. And I certainly have never bought into the idea that the local governments spending funds are either. Two, I have been seeing with my own eyes what I thought to be misallocations, but at least half the time when I raise them to people, I get a response like, “well surely the people in Beijing are better equipped to know whether 3 million vacant condos, bridges to nowhere, and train stations in nowhere make economic sense than you are.” I have never thought that is the right question and I have always felt that many of those who refuse to admit China can do no wrong economically are so tied to the system as to have lost any real perspective. Three, the analysis is absolutely first rate and it has been a long long time since i have seen an analysis of Chinese economy of which I could say that.
The article focuses on China’s investment in electric car technology as an example of misallocated capital and it does a great job of explaining why even an investment so initially appealling as that can be a big mistake.
Pettis explains why he sees China having missollacted its capital:
Of course the question of whether or not China is misallocating capital can be endlessly debated because it is very hard to prove except in retrospect. I would argue that there are several reasons why we should believe that capital has been wasted on a large scale for many years. The first reason is simply historical precedents, something which unfortunately rarely enters into most economic analysis. No country in history that has had anywhere near the growth in investment as China has not had a serious problem in subsequent years, in which debt rose to crisis levels and growth ground to a stop.
The fact that China is so poor is often proposed as an argument as to why this cannot also be the case for China, but of course this is a nonsensical argument. Poorer countries with lower levels of worker productivity are less able, not more able, to absorb very high levels of investment. This may seem counterintuitive at first, but only if you believe that there is a single optimal level of investment for every country regardless of its specific conditions. If the purpose of investment is to save labor and labor cost, then it should be clear that the lower the level of worker productivity and the cheaper and more abundant the amount of labor, the less investment in capital stock is justified.
This is why when so many analysts compare the per capita capital stock of China with that of the US or Japan, and then announce that this proves China has a long ways to go before it runs out of investment opportunities, I am always surprised, and even a little skeptical about their economic backgrounds. This comparison simply does not make sense.
If it did, overinvestment crises would be largely limited to rich countries, not poor countries – something that is certainly not confirmed by history. Anyway I find bizarre the idea that the best comparison for China, one of the poorest countries in the world even if you accept the validity of GDP numbers and ignore the very low GDP share of household income, is the US or Japan, two of the richest and most technologically advanced countries in the world.
But I think there are more formal reasons to believe that China is misallocating capital. Common sense suggests that when there is massive investment with
- very little accountability,
- severely distorted prices,
- an incentive structure that concentrates the benefits of investment in specific jurisdictions and over a short time period while spreading the costs throughout the national banking system and over the debt repayment period (which can be decades),
- no or very limited budget constraints,
- factional and regional conflicts, and
- shifts in responsibility as the instigators of the investment are promoted (often because of the positive impact of their own investment initiatives),
it would be a rare system in history that did not tend towards substantial capital misallocation.
Certainly the evidence on SOE investment suggests that this is indeed what happened. A number of studies have suggested that if over the past decade you add up direct subsidies, the impact of monopoly pricing (which is of course simply a tax on households) and the interest rate subsidy, they total anywhere from six to ten times the aggregate profitability of the SOE sector. This means that unless the externalities associated with the SOEs are also at least six to ten times their aggregate profitability, they are actually value destroyers.
If you have any interest at all in China’s economy, you really should read the whole article. I buy it. Do you?
