Economic simulations show that migration lowers the real wage for both countries receiving and sending immigrants; however, the effect of this decrease is based on the goods and services consumed by an individual. According to Kennan “these gains are associated with a relatively small reduction in the real wage in developed countries, and even this effect disappears as the capital–labor ratio adjusts over time.” Therefore, the number of workers in both receiving and sending countries would double by the current population of workers.
