2 The impacts of international migration In this question, we continue using the setup above. Suppose Brazil is already integrated to international trade. Suppose a large number of Brazilian workers leave Brazil. 1. Draw a new labor market diagram. Using this diagram, show the impact of emigration. Label carefully the pre-emigration and post-emigration labor supply, wages, and employment in each sector. 2. Explain carefully how emigration impacts: (a) the marginal product of labor (b) the marginal product of land (c) the marginal product of capital. 3. What happens to the real returns to labor, land, and capital? Explain your answer carefully
