The infant industry argument is an economic rationale for trade protectionism. The core of the argument is that nascent industries often do not have the economies of scale that their older competitors from other countries may have, and thus need to be protected until they can attain similar economies of scale. The logic underpinning the argument is that trade protectionism is costly in the short run but leads to long-term benefits.
Alexander Hamilton first codified the infant industry argument.
Protectionism, sometimes referred to as trade protectionism, is the economic policy of restricting imports from other countries through methods such as tariffs on imported goods, import quotas, and a variety of other government regulations. Proponents argue that protectionist policies shield the producers, businesses, and workers of the import-competing sector in the country from foreign competitors and raise government revenue. Opponents argue that protectionist policies reduce trade, and adversely affect consumers in general as well as the producers and workers in export sectors, both in the country implementing protectionist policies and in the countries against which the protections are implemented.
Political poster by the British Liberal Party presenting their view of the differences between an economy based on free trade versus one based on protectionism. The free trade shop is shown as full of customers due to its low prices. The shop based on protectionism shows higher prices, a lesser selection of goods, and a lack of customers. Animosity between the "protected" business owner and the regulator is also depicted.
