Introduction:
Paul Samuelson's contributions to trade theory and international economics
just wonderful. Virtually every undergraduate or graduate student anywhere in the world will be asked to understand his Stolper-Samuelson claims: cost-sharing factors. These statements certainly tell us why trade liberalization tends to favor relatively wealthy factors of production (skilled labor, in the case of the United States), why trade in goods can in many ways equalize opportunities as effectively as human trafficking. . Capital In fact, it's safe to say that whoever the great economist of the 22nd century is, he will assimilate and consolidate the ideas that Samuelson formulated in the mid-20th century.

achievement. Which is probably even more evident in Samuelson's business investments.
its vitality in the current debate about globalization. If a few taxi drivers in Shanghai were to go to university rather than graduate school (which is not to be expected in Cambridge, Massachusetts), they would still understand that trade with the United States increases the wages of Chinese workers. As most Americans understand, the shrinking of a country's manufacturing base has little to do with international trade. Indeed, the growing wage gap between skilled and unskilled workers in the United States (in all developed countries) is one of the most controversial and complex economic and political issues of our time. There is still a lot of debate about what drives this growing differentiation, especially to what extent it is due to globalization, to what extent it is driven by changing technologies that contribute to the emergence of a skilled workforce. Nevertheless, Samuelson's ideas have contributed greatly to the framework that economists use to ask such questions and quantify possible answers.
In this short essay, I will not attempt to give a technical description of Samuelson's main business theories, as they can be found (at various levels) in any economics textbook, from introductory to advanced, including, of course, many generations.
