Peopling of New York City, Lecture 4 slides

  1. 1. Economics of Immigration
  2. 2. The Age-Earnings Profiles of Immigrant and Native Men in the Cross Section 9,000 Immigrants 8,000Annual Earnings (1970 Dollars) Natives 7,000 6,000 5,000 4,000 20 25 30 35 40 45 50 55 60 65 Age
  3. 3. The Decision to Immigrate• Skills vary across country-of-origin (or source country) immigrant groups.• The general rule: Workers decide to immigrate if U.S. earnings exceed earnings in the source country. – The decision ultimately depends on individual skills and the returns to those skills in the source and destination countries.

  7. 7. The Distribution of Skills in the Source Country Frequency NegativelySelected - Immigrant Flow Positively-Selected Immigrant Flow s N s P Skills The distribution of skills in the source country gives the frequency of workers in each skill level. If immigrants have above-average skills, the immigrant flow is positively selected. If immigrants have below- average skills, the immigrant flow is negatively selected.
  8. 8. The Self-Selection of the Immigrant FlowDollars Dollars Positive Selection U.S. Source Country Source U.S. Country Do Not Move Do Not Move Move Move sP Skills sN Skills (a) Positive selection (b) Negative selection
  9. 9. Policy Application: Economic Benefits of Migration• The immigrant surplus is a measure of the increase in national income that occurs as a result of immigration. (The surplus accrues to natives.)• Immigration raises national income by more than it costs to employ immigrants.

  11. 11. Decline in U.S. Incomes• The previous graphs shows that when U.S. incomes decrease (shift down in the returns- to-skills curve): – Fewer workers migrate to the U.S. – The type of selection (positive vs. negative) doesn’t change.
  12. 12. Policy Application: Labor Flows in Puerto Rico• The case study of Puerto Rico confirms an important insight of the Roy model: skills flow to where they receive their highest return. – The rate of return to skills is much higher in Puerto Rico than in the United States, so the Roy model predicts that a relatively higher fraction of the least-educated Puerto Ricans would leave the island. – As of 2000, nearly 45 percent of Puerto Rican-born working age men who lacked a high school diploma had moved to the United States. In contrast, only 30 percent of working age men with at least a college education had moved to the United States.
