Mercantilism was an economic theory and practice, dominant in Europe from the 16th to the 18th century, that promoted governmental regulation of a nation’s economy for the purpose of augmenting state power at the expense of rival national powers. It is the economic counterpart of political absolutism. Mercantilism includes a national economic policy aimed at accumulating monetary reserves through a positive balance of trade, especially of finished goods. Historically, such policies frequently led to war and also motivated colonial expansion. The Mercantilism theory varies in sophistication from one writer to another and has evolved over time. High tariffs, especially on manufactured goods, are an almost universal feature of mercantilism policy. Other policies have included:

• Building overseas colonies;
• Forbidding colonies to trade with other nations;
• Monopolizing markets with staple ports;
• Banning the export of gold and silver, even for payments;
• Forbidding trade to be carried in foreign ships;
• Export subsidies;
• Promoting manufacturing with research or direct subsidies;
• Limiting wages;
• Maximizing the use of domestic resources;
• Restricting domestic consumption with non-tariff barriers to trade.

Mercantilism in its simplest form is bullionism, but mercantilist writers have emphasized the circulation of money and reject hoarding. Their emphasis on monetary metals accords with current ideas regarding the money supply, such as the stimulative effect of a growing money supply. Specie concerns have since been rendered moot by fiat money and floating exchange rates. In time, the heavy emphasis on money was supplanted by industrial policy, accompanied by a shift in focus from the capacity to carry on wars to promoting general prosperity. Mature neo-mercantilist theory recommends selective high tariffs for “infant” industries or to promote the mutual growth of countries through national industrial specialization
