The infant industry argument makes intuitive sense. It also has a sense of fairness about it. As Mill writes, “The superiority of one country over another in a branch of production, often arises only from having begun it sooner,” as opposed to making a better product.
But such a scheme does not work in practice. The tinplate industry, protected by a McKinley-era tariff, is often cited as an infant industry tariff success story. Or it was, until Doug Irwin looked closely in a famous paper, finding that “Although the tariff accelerated the industry’s development, welfare calculations suggest that protection does not pass a cost-benefit test.” After all, a tariff that helps one industry harms other industries, as well as consumers.
And as anyone with a basic knowledge of public choice theory can tell you, politicians and businessmen are both self-interested. Tariffs are an open invitation to corruption and rent-seeking, even if their stated intentions are pure. Businesses enjoy having less competition, and politicians enjoy the campaign contributions, fancy dinners, and ribbon-cutting ceremonies. The result is rather the opposite of a virtuous cycle.
But even supposing pureness of motives, there is a knowledge problem at work. As Iain Murray and I point out in our recent study “Traders of the Lost Ark”:
Politicians and regulators are no more adept than anybody else at foreseeing which companies or industries will dominate tomorrow’s economy.
It’s hard to make predictions, especially about the future. Moreover, as George Mason University economist Don Boudreaux points out in his excellent book “Globalization”:
Will politicians exhibit the political will power to remove protection from protected industries once those industries have matured? Might protection of an industry weaken it—causing it to depend for its survival on political favors—rather than strengthen it? Will the certain costs incurred today to protect an infant industry be exceeded by the (necessarily) uncertain benefits that only come in the future when the domestic industry has matured?
In short, infant industry trade barriers sound nice, but they invite corruption, and nobody knows what they’re doing anyway. Empirical research also shows they don’t work. Protectionists must look elsewhere for a good argument for trade barriers.
