- Princeton economist that argued comparative advantage is not an “infallable principle” for commercial policy

- Argued that some industries might warrant *permanent* protection
  - recall infant industries argument is just about *temporary* protection

- Main argument hinges on .hi[increasing returns to scale] (decreasing cost industry)

> “protection to manufactures may advantageously be continued much longer than would seem adequate to cover the infant stage, whether or not the industry could maintain itself without such aid,” (p.200).

> “[I]t may be to a country’s economic advantage to protect an industry which could not grow up or survive without protection and which never will be able to survive without it, an industry which has no comparative advantage when the protective duty is first levied nor ever attains one under it,” (pp.202-203).

- Country A specializes in agriculture

- More labor allocated to agriculture, lowers `$MP_L$` in agriculture

- Took major issue with a footnote in Graham:

> “The reasoning in the text simply assumes that a decreasing [average] cost is obtained by an expansion of the production of [manufacturing]; whether the cause of it be external or internal economies is immaterial to the theory, though it would, of course, affect the degree of its applicability,” (p.204n).

In spite of the weight of authority which may be cited for such economies [i.e. Marshall], I have never succeeded in picturing in them in my mind, or finding any convincing reason to believe they exist; and the hypothetical examples cited by Professor Graham...has not assisted me in doing so.

The scope for application of the argument is extremely limited, especially as it seems difficult even to suggest plausible hypothetical cases of the existence of genuine technological external economies...[Graham’s increasing returns argument for protectionism is] little more than a theoretical curiosity” (pp.480-481).

An additional design raises the productivity of all future individuals who do research, but because this benefit is nonexcludable, it is not reflected at all in the market price for designs. The second and an equally important reason...is that research produces an input that is purchased by a sector that engages in monopoly pricing.

This finding suggests that free international trade can act to speed up growth. It also suggests a way to understand what it is about developed economies in the twentieth century that permitted rates of growth of income per capita that are unprecedented in human history. The model also suggests that low levels of human capital may help explain why growth is not observed in underdeveloped economies that are closed and why a less developed economy with a very large population can still benefit from economic integration with the rest of the world," (p.S99)

> President Trump made good on his 2016 campaign pledge to the steel industry, slapping 25% tariffs on foreign-made steel...

> The tariffs succeeded in pushing down steel imports and—for a short time—resulted in higher prices for domestic steelmakers...

> Yet the tariffs haven’t produced the steelmaking renaissance and robust job growth in America’s industrial heartland that Mr. Trump promised. What’s more, the tariffs have hurt U.S. manufacturers, including those in the automotive and appliance sectors, who say the duties on steel and aluminum continue to keep their metal costs higher than what overseas competitors pay.

> With the expanded production, about 6,000 jobs were added to the U.S. steel industry’s workforce after tariffs started in 2018, according to the Census Bureau. By the end of 2019, though, those gains evaporated as steel demand and prices sank [but h]igher prices also made steel more expensive for manufacturers that buy it, leading to the loss of about 75,000 U.S. manufacturing jobs, according to a study released late last year by the Federal Reserve Board of Governors.

> U.S. President Donald Trump says China pays the tariffs he has imposed on $250 billion of Chinese exports to the United States.

> But that is not how tariffs work. China’s government and companies in China do not pay tariffs directly. Tariffs are a tax on imports. They are paid by U.S.-registered firms to U.S. customs for the goods they import into the United States.

> Importers often pass the costs of tariffs on to customers - manufacturers and consumers in the United States - by raising their prices.
