Tyler Cowen in the New York Times:
Keynesian economics holds that aggregate demand — the sum of all consumption, investment, government spending and net exports — drives stability, and that government can and should help in difficult times. But the Austrian perspective, developed by the Austrian economists Ludwig von Mises and Friedrich A. Hayek, and championed today by many libertarians and conservatives, emphasizes how government policy often makes things worse, not better.
Economists of all stripes agree that China may be in for a spill. John Maynard Keynes emphasized back in the 1930s the dangers of speculative bubbles, and China certainly seems to have had one in its property market.

The Austrian perspective introduces some scarier considerations. China has been investing 40 percent to 50 percent of its national income. But it is hard to invest so much money wisely, particularly in an environment of economic favoritism. And this rate of investment is artificially high to begin with.
Beijing is often accused of manipulating the value of its currency, the renminbi, to subsidize its manufacturing. The government also funnels domestic savings into the national banking system and grants subsidies to politically favored businesses, and it seems obsessed with building infrastructure. All of this tips the economy in very particular directions.
The Austrian approach raises the possibility that there is no way for China to make good on enough of its oversubsidized investments. At first, they create lots of jobs and revenue, but as the business cycle proceeds, new marginal investments become less valuable and more prone to allocation by corruption. The giddy booms of earlier times wear off, and suddenly not every decision seems wise. The combination can lead to an economic crackup — not because aggregate demand is too low, but because the economy has been producing the wrong mix of goods and services.
Lots of earlier discussion of the problems in China’s economy here.
