Question 04 continued. Repatriation is what the U.S. government did to some Mexican workers in the Great Depression of 1930s. According to different estimates 500,000 to 2,000,000 Mexicans were deported, some actually U.S. citizens. The dominant theory was that these workers were taking the jobs of American workers. Therefore, if they left, Americans would take those jobs and unemployment among American workers would go down. Moreover, their presence in the U.S. job markets was keeping the wages down. If they left, the American wages and standards living would increase. However, new research shows that, cities that experienced greater number of repatriations, experienced lower employment and lower wages afterwards. This is due to the resulting reductions in the amount of complementary skills and positive production externalities mentioned in the previous questions. For example, when the mechanics leave, the auto-shop has to close down; when the chef leaves, waiters lose their jobs; when the farm worker leaves, he takes with him some useful knowledge that he could teach the natives. Therefore, let's assume that after repatriation, demand for labor decreases by 3,000 workers (demand shifts leftward by 3,000 units).Therefore, let's assume that after repatriation, demand for labor decreases by 3,000 workers (demand shifts leftward by 3,000 units). After repatriation, wage rate = dollars. Before repatriation, number of natives employed = persons. After repatriation, number of natives employed = persons.Now assume the opposite of what we had in the previous questions. Assume that the supply-of-labor in that file already includes immigrants that are already in the country and have jobs. In particular, suppose that there are currently 3,000 immigrant workers in the country, all employed. Now imagine that the government repatriates (deports) all these 3,000 workers back to their countries of birth. You might think that this is an utterly unrealistic scenario. But, this is what the U.S. government did to some Mexican workers in the Great Depression of 1930s. The government deported an estimated 500,000 to 2 million people of Mexican origin to Mexico. Actually, many of the deported workers were American citizens. The dominant theory at the time was that these workers were taking the jobs of American workers. Therefore, if they left, American workers would take those jobs and unemployment among American workers would go down. Moreover, presence of the immigrants in the U.S. job markets was keeping the wages down. If they left, the American wages and standards of living would increase. Let's first understand the logic of this dominant theory using our simple model.\fLet's first understand the logic of this dominant theory using our simple model. After repatriation, wage rate = dollars. Before repatriation, number of natives employed = 4000.00 persons. After repatriation, number of natives employed = 1000.00 persons.
