First, all the theoretical arguments in favour of complete free trade fail, and need not detain us.
Nor is the case for “infant industry protectionism” an endorsement of endless protectionism or tariffs on all goods, but the view that where domestic industries can be developed and generate positive externalities throughout an entire economy, through increasing returns to scale, synergies and cluster effects (Reinert 2007), they can be strongly aided in their early stages of development by selected tariffs on foreign imports.
The crucial point is that the creation of industries that gave increasing returns to scale (often in manufacturing), rather than dead-end “diminishing returns to scale,” is what marks successful economic development. Once the new manufacturing sectors become internationally competitive, it is possible to reduce or eliminate tariffs. Note also that this policy is perfectly compatible with the fact the other types of tariffs or poorly targeted tariffs can be harmful to economic development.
It is, above all, the structure of tariffs not average tariff rates that is the key to successful infant industry protectionism (Tena-Junguito 2009).
The US is a case in point. Protectionism as a modern economic theory was essentially born in the US in the thought of Alexander Hamilton and his Report on Manufactures (1791), although he drew on earlier mercantilist ideas (Bairoch 1993: 33).
Bairoch (1993: 34) sees US economic history as divided into these phases:
(1) 1816–1846The American Civil War saw the victory of the doctrine of protectionism after a somewhat more liberal era in the 1850s (Bairoch 1993: 35).
A very strong protectionist phase
A slightly reduced, but still moderately protectionist phase.
An era of strong protectionism.
Although the average level of tariffs is not necessarily a guide to how effective and well targeted tariffs were in each country, nevertheless we can see the level of protectionism in the United States as compared with other Western nations in 1875 in the following data:
Average Level of Duties on Manufactured goods 1875The US tariff regime aided manufacturing industries, and Bils (1984) shows how the US cotton textile industry would have been largely wiped out in the early 19th century if it had not been for protectionism.
