The Factor Price Equalization Theorem Given all the assumptions of the Heckscher- Ohlin model , free international trade will lead to the international equalization of individual factor prices. Note that two important assumptions must hold to have factor price equalization: (1) no barriers to trade (2) access to identical technology 42

Immigration to the US Today The category of workers without a high school degree has the largest percentage of foreign born workers. The group of workers with Ph.D.s has the next largest percentage of foreign-born workers. The middle educational levels, which comprise about 80% of the U.S. labor force, has the lowest percentage of foreign-born workers. 45
Long-run Effects of Immigration Assume that all factors are free to move between industries. Assume that only capital and labor are used to produce shoes and computers. Assume that shoes and computers can be traded internationally without any trade barriers. Assume that labor can move between countries. This is an extension of the HO model. 46

Long-run Effects of Immigration Computers are capital intensive and shoes are labor intensive. As before, LS/KS > LC/KC and KC/LC > KS/LS Again we can see the PPF and show the free- trade equilibrium output at point A (next slide). The tangency between the PPF and the world relative price line under free trade. How is the equilibrium affected by the inflow of labor due to migration? 47

Long-run Effects of Immigration on Industry Outputs Because shoes are labor intensive, the increase in labor will lead the PPF to shift out more in the direction of shoes (the next slide). Since the world prices are unchanged (we are looking at a small open economy that has no influence on the world prices), the economy moves to equilibrium at point B (the next slide). More shoe production and less computer production This only holds in the long run. 49
Long-run Effects of Immigration on Industry Outputs Output of Computers, QC Output of Shoes, QS Relative Price of Computers, - PC/PS Shift in Home PPF due to immigration An increase of both capital and labor in shoe production causes an increase in shoe output and a decrease in computer output A B 50

Long-run Effects of Immigration on Industry Outputs The long run result we just showed was named after economist T.N. Rybczynski, who first discovered it. Rybczynski Theorem: In the Heckscher-Ohlin model with two goods and two factors, an increase in the amount of a factor found in an economy will increase the output of the industry using that factor intensively and decrease the output of the other industry.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
