Since 1950, world imports and exports have grown at the remarkable rate of about 10% a year. Even during the economic slowdown of the 1980s, international trade continued to expand at 5% a year. The result has been that prosperity no longer depends on a large domestic economy--even tiny nations can hawk their wares in the world market.
In fact, small nations now have advantages in the competition for international markets. Economic efficiency requires them to concentrate on only a few products and services, so they often specialize in niches that are too small for large nations to fill.

Their goods and services tend to be less exposed to trade quotas and other restrictions, since they don't amount to enough to affect producers in large countries.
