Mercantilism

Mercantilism, the dominant economic doctrine of European states from roughly 1500 to 1800, rested on a simple and largely accurate observation about the world as it then existed: national power derived from wealth, wealth derived from money, and money accumulated through trade surpluses. A nation that exported more than it imported accumulated gold and silver -- the universal currency of international trade -- and that accumulation could be converted into armies, navies, and administrative capacity.

The practical policy implications were extensive. Governments regulated trade intensively, imposing tariffs on imports, subsidizing exports, and using colonial relationships to ensure that raw materials flowed to the metropole and manufactured goods flowed out. The Navigation Acts, which required that English colonial trade be conducted in English ships, exemplified this logic: commerce was managed as an instrument of state power rather than allowed to find its own equilibrium.

Mercantilism has been routinely dismissed by economists since Adam Smith's devastating critique in The Wealth of Nations (1776). Smith argued that trade was not a zero-sum competition in which one nation's gain was another's loss, but a positive-sum process in which specialization and exchange increased aggregate wealth. His critique was largely correct on the economics -- but less decisive than advertised on the policy.

Smith's critique of mercantilism was economically powerful. But the nations that became industrial powers in the nineteenth century -- Britain, the United States, Germany, Japan -- did so behind substantial tariff barriers, not through free trade.Ha-Joon Chang, Bad Samaritans (2007)

The mercantilist emphasis on managed trade and national industrial development did not disappear with the Enlightenment -- it went underground, to reemerge periodically whenever free-trade doctrine proved inadequate to the task of national development. Alexander Hamilton's Report on Manufactures (1791) argued explicitly for tariff protection of infant American industries. Friedrich List's National System of Political Economy (1841) provided the theoretical framework for German industrialization. The East Asian developmental states of the twentieth century -- Japan, South Korea, Taiwan -- deployed mercantilist instruments with remarkable success (Chang, 2007).

What mercantilism captured, and what later liberal economics tended to obscure, was the role of state power in constituting markets rather than merely regulating them. Trade does not happen in a vacuum; it happens within institutional frameworks that determine whose products reach which markets on what terms. Those frameworks are always shaped by political relationships, and the nations that write the rules generally write them to their advantage.
