Import restriction

In economics, protectionism is the economic policy of restraining trade between states (countries) through methods such as tariffs on imported goods, restrictive quotas, and a variety of other government regulations. Protectionist policies protect the producers, businesses, and workers of the import-competing sector in a country from foreign competitors. However, they hurt consumers in general, and the producers and workers in export sectors, both in the country implementing protectionist policies, and in the countries protected against.

There is a broad consensus among economists that protectionism has a negative effect on economic growth and economic welfare, while free trade and the reduction of trade barriers has a positive effect on economic growth. However, liberalization of trade can cause significant and unequally distributed losses, and the economic dislocation of workers in import competing sectors.

A variety of policies have been used to achieve protectionist goals. These include:

In the modern trade arena many other initiatives besides tariffs have been called protectionist. For example, some commentators, such as Jagdish Bhagwati, see developed countries efforts in imposing their own labor or environmental standards as protectionism. Also, the imposition of restrictive certification procedures on imports are seen in this light.

Further, others point out that free trade agreements often have protectionist provisions such as intellectual property, copyright, and patent restrictions that benefit large corporations. These provisions restrict trade in music, movies, pharmaceuticals, software, and other manufactured items to high cost producers with quotas from low cost producers set to zero.

Historically, protectionism was associated with economic theories such as mercantilism (which focused on achieving positive trade balance and accumulating gold), and import substitution.

In the 18th century, Adam Smith famously warned against the "interested sophistry" of industry, seeking to gain advantage at the cost of the consumers.Friedrich List saw Adam Smith's views on free trade as disingenuous, believing that Smith advocated for freer trade so that British industry could lock out underdeveloped foreign competition.
