Suppose a worker’s skill is captured by his efficiency units of labor. The distribution of efficiency units in the population is such that worker 1 has one efficiency unit, worker 2 has two efficiency units, and so on. There are 100 workers in the population. In deciding whether to migrate to the United States, these workers compare their weekly earnings at home ( w0) with their potential earnings in the United States (w1).The wage-skills relationship in each of the two countries is given byw0 = 700 + 0.5sandw1 = 670 + swhere s is the number of efficiency units the worker possesses.a. Assume there are no migration costs. What is the average number of efficiency units among immigrants? Is the immigrant flow positively or negatively selected?b. Suppose it costs $10 to migrate to the United States. What is the average number of efficiency units among immigrants? Is the immigrant flow positively or negatively selected?

Assume their marginal productivity and, therefore, their wages are wh = $20 and wl = $16, and that both types can use college education to signal high ability. The cost of college education for low-ability workers is cl = $5 whereas the cost for high-ability workers is ch = $2. How much do firms pay to each worker type when they cannot differentiate them?

Poverty arises when the rate of return on capital exceeds the growth rate of income. Poverty arises from the gap between savings and investment and can be remedied by foreign aid. Poverty arises when capital market imperfections restrict the amount individuals can borrow. Poverty arises when a country invests in the traditional sector with constant returns to scale, and not in the modern sector with increasing returns.arrow_forward
- A5. Suppose that the initial rural distribution of income is (1, 2, 3, 4) while the initial urban distribution is (3, 4). The poverty line is 2, so the overall poverty rate (headcount index) is 1/3. Now imagine that all of the rural poor move to urban areas and each of them gains 20% in real income. Verify that the overall poverty rate falls to 1/6, yet the urban poverty rate rises from zero to 1/4.arrow_forwardWhat do we mean by “economic activity”?Economic Activity we mean the area of our social interactions in which people provide for their material needs and for those of their fellow human beings. It involves the production, the distribution, and the consumption of goods and services. #164. What does the Bible say about poverty and riches?Anyone who follows Jesus must never forget that first and foremost we are supposed to be ‘rich toward God’ (Lk.12:21). To become rich in material things is not a particularly Christian goal in life. And to be materially rich is not a sure sign of God’s special grace. Jesus teaches us to pray: ‘Give us this day our daily bread’ (Mt.6:11). With these words we ask the Father for all that we need for our earthly life. We do not strive for luxurious possessions but for the goods required for a happy life in moderate prosperity, the support of a family, works and charity, and participation in culture and education, as well as further development. #175.

Person 1 has h1 units of time available and takes l1 units of leisure time, and person 2 has h2 units of time available and takes l2 units of leisure time. Collectively, the two persons in the household care about their total consumption c, and their total leisure l=l1+l2, and they have preferences over their total consumption and total leisure just as specified in the course. But person 1 faces a market wage w1, and person 2 faces a market wage w2, with w1 > w2. 1) Draw the budget constraint faced by the two-person household. What will the household do, that is, how much does each household member work? 2) What happens if w2 rises? (w1 > w2 still holds) 3) Explain your results and interpretarrow_forward
