The return of Thomas Mun
By Martin Hutchinson

China's recent announcement that it would use its US$2 trillion of foreign reserves to boost its companies' overseas acquisitions tells us that its economic beliefs are neither those of Adam Smith, nor of Karl Marx, but of the 17th century mercantilist Thomas Mun. It is becoming clear that in economics, unlike in "hard" sciences, old belief systems never die.

Mun (1571-1641) wrote a classic magnum opus England's Treasure by Foreign Trade. Published only after his death in 1664, it was nevertheless very influential. Mun had been a director of the East India Company, and, unlike earlier theorists, believed that foreign trade was beneficial. However, he didn't hold with any high-faluting nonsense like comparative advantage or maximization of global economic welfare. For Mun, the purpose of foreign trade was to export more than you imported and, consequently, amass a huge store of foreign "Treasure," which you could then use to found colonies that would take control of natural resources.

To further this objective, countries should: cut back domestic consumption as far as possible; increase the use of land and other domestic resources to reduce imports; encourage the export of goods made with foreign raw materials; and export goods with price-inelastic demand because profits would be greater.

Mun's theory made sense in the 17th century economic jungle - and today it obviously makes sense to China. The country's currency, the yuan, is undervalued, so exports consistently exceed imports. Domestic consumption is kept low and savings high, both of which suppress imports. In industries such as automobiles where consumer demand is inevitable, foreign manufacturers are forced into domestic joint ventures, so that domestic manufacturers can be developed to replace imports. Domestic agriculture and resource extraction efforts are intensive.

China has set up free-trade zones, in which foreign parts are assembled into goods that are then exported. Finally, the country has amassed a gigantic store of $2 trillion of "Treasure," which is now to be used to assist in foreign acquisitions. Those acquisitions are not to be on Wall Street, as Prime Minister Wen Jiabao helpfully explained, but in natural resources, where China can assure itself of exclusive raw materials supplies for decades to come.

But, what if no one wants to buy your products?
