In one modern view, trade exists due to specialization and the division of labour, a predominant form of economic activity in which individuals and groups concentrate on a small aspect of production, but use their output in trade for other products and needs. Trade exists between regions because different regions may have a comparative advantage (perceived or real) in the production of some trade-able goods – including the production of scarce or limited natural resources elsewhere. For example, different regions' sizes may encourage mass production. In such circumstances, trading at market price between locations can benefit both locations. Different types of traders may specialize in trading different kinds of goods; for example, the spice trade and grain trade have both historically been important in the development of a global, international economy. Retail trade consists of the sale of goods or merchandise from a fixed location, online or by mail, in small or individual lots for direct consumption or use by the purchaser.

Historically, openness to free trade substantially increased in some areas from 1815 until the outbreak of World War I in 1914. Trade openness increased again during the 1920s but collapsed (in particular in Europe and North America) during the Great Depression of the 1930s. Trade openness increased substantially again from the 1950s onward (albeit with a slowdown during the oil crisis of the 1970s). Economists and economic historians contend that current levels of trade openness are the highest they have ever been.

Etymology

Trade is from Middle English trade ("path, course of conduct"), introduced into English by Hanseatic merchants, from Middle Low German trade ("track, course"), from Old Saxon trada ("spoor, track"), from Proto-Germanic *tradō ("track, way"), and cognate with Old English tredan ("to tread").

Commerce is derived from the Latin commercium, from cum "together" and merx, "merchandise."
