in its external accounts to slow or even reverse the decline in its share, other major manufacturers who don't intervene in their external accounts must balance the combined actions of China and the US by reducing their shares of global manufacturing.
This is just how arithmetic works. If the world's largest manufacturer (China) intervenes in its external accounts to increase its share of global manufacturing, and the world's second-largest manufacturer (the US) intervenes...

The point is that any economy that takes steps to limit domestic consumption, including of imported consumer goods, will tend to raise exports relative to imports. Comparative advantage, on the contrary, is expressed only in balanced trade.
The fact that academic economists continue to insist that trade surpluses are simply an expression of comparative advantage shows not only how little they understand comparative advantage, but also how little they know about the world outside.

Some economists insist that you cannot say that a market is in a bubble when presumably rational investors say it isn't. But the economy itself can shift investment away from"rational" behavior as long as agents have different risk preferences and realistic time horizons.
That is why these sequences are so dangerous – they can take in the whole economy. When eventually either excessive debt or stricter policies rein in the market, it is not just property developers who suffer. A wide range of agents can get caught up in the adjustment.
At first this shift in behavior further reinforces the market, as more and more agents find themselves effectively forced to speculate in rising property prices. This automatically increases the overall economy's bias toward "excessive" risk-taking.
Local governments that cut taxes and rely more on rising land revenues outperform those that don't. Households that buy bigger apartments than they can afford get rich quicker. Property developers that buy land without restraint grow faster than those that don't.
As the market shifts towards excessive risk taking, those that don't must drop out. For example businesses that buy more land than they need for future expansion outperform those that don't. Banks that lend aggressively against real estate learn that they can never lose.
In that case excessive risk-takers always outperform, which means that not only do they expand their share of their market year after year, but also that they teach those that do not share their appetite for excessive risk taking that they will go out of business.
