8. Valuing human capital with wage growth: To make the calculation of the present discounted value of a worker's human capital more realistic, suppose labor income starts at $50,000 initially, but then grows at a constant rate of 2% per year after that. Let w, be labor income in year t, so that w; = Wo(1 + , where wo = $50,000 and g = 0.02. The steps below will walk you through the problem. 1. If the interest rate is R, what is the formula for the present discounted value today (in year 0) of labor income from a particular future year t? 2. Now add up these terms from t = 0 to = 45 to get a formula for the present discounted value of labor income. Your answer should look something like that in equation (7.12). 3. Write your answer to part (b) so that it takes the form of the geometric series: pdv = w.(1 + a + a? + a³ + . + a*5). ... What is the value of a that you find? 4. Apply the geometric series formula to compute the present discounted value for the case of R= 0.04, R = 0.03, and R= 0.02. What weird thing happens (and why) when R= 0.02? 5. Comment on vour results.

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 that potential migrants make decisions only based on comparisons of their expected incomes. Now suppose the rural wage is $1 per day. Urban modern sector employment can be obtained with 0.25 probability and pays $3 per day. The urban traditional sector pays $0.40 per day. (d) What simplifying assumptions are needed to make this a valid conclusion? (e) Now, what would the urban traditional sector daily income have to be to induce no net rural-urban migration? (f) If wages in all sectors are inflexible, what else adjusts in this model to lead to equilibrium (how much does it adjust and what is the intuition)?

Suppose that an additional year of schooling raised wages by 7 percent in 1970, regardless of the worker’s race or ethnicity. Suppose also that the wage differential between the average white and the average Hispanic was 36 percent. Finally, assume education is the only factor that affects productivity, and the average white worker had 12 years of schooling in 1970, while the average Hispanic worker had 9 years. By 1980, the average white worker had 13 years of education, while the average Hispanic worker had 11 years. A year of schooling still increased earnings by 7 percent, regardless of the worker’s ethnic background, and the wage differential between the average white worker and the average Hispanic worker fell to 24 percent. Was there a decrease in wage discrimination during the decade? Was there a decrease in the share of the wage differential between whites and Hispanics that can be attributed to discrimination?
