Scenario 38-1. Consider the following OLS model applied to the data for workers wages and years of schooling, where e; stands for the residual:WAGE = -10.7+ 3.16 × SCHOOL + e;-(20.7) (1.35)Refer to Scenario 38-1. Suppose that the residual term is non zero and reflects all the forces that influence wages other than years of schooling.

The following equations have been estimated by Ordinary Least Squares (OLS), where Y denotes annual earnings, P job evaluation points, and the subscripts m and f denote male and female respectively: Ym = 5000 + 100Pm Yf = 4000 + 80Pf Assume the average job evaluation score was 300 points in male-dominated jobs and 200 points in female-dominated jobs. What is the average pay in male-dominated jobs and in female-dominated jobs? Use a Oaxaca decomposition to determine the average pay differential between male and female dominated jobs into two components: a portion attributable to the difference in job evaluation points (valued according to the male pay for such points) and a portion attributable to differences in pay for the same job evaluation points. Use that same decomposition, but this time evaluate the differences in job evaluation points according to the female pay for such points.
If one worker can pick $10 worth of grapes and two workers together can pick $24 worth of grapes, the Multiple Choice marginal revenue product of the second worker is $14. marginal revenue product of each worker is $17. data given are insufficient to determine the marginal revenue product of either worker. marginal revenue product of the first worker is $14.
Consider an individual aged 64 who is eligible to collect full social security (public pension) benefits of $6,000 for a year. They have no other income but can work at a weekly wage rate of $600 for a maximum of 52 weeks. Receipt of benefits from the social security program is retirement tested. Specifically, the individual can earn up to $9,000 in annual wage income without a reduction in benefits; however, after $9,000 of earnings, benefits are reduced by 50% for every dollar earned, until the benefits are exhausted. a) Carefully draw and label the budget constraint for this individual. b) Suppose previously there was a retirement test, and then the test is eliminated, i.e., the individual now is allowed to keep all benefits, irrespective of their labour earnings. How would this affect the individual’s labour supply? Question Two David is a 70-year-old accountant. After serving his accounting firm for 45 years, David decides to retire soon. David has great passion for vintage cars…
Assume that the coefficient estimated in the second regression is correct. Forget about the effect of the Return variable, whose effect seems small and statistically insignificant. Calculate the correlation between Female and In(MarketValue) using the omitted variable bias equation. Let X Female, u=MarketValue, and =0.51. The correlation between Female and In(MarketValue), Px is -0.333. (Round your response to three decimal places.) Are large firms more likely to have female top executives than small firms? A. Yes. B. There is no relationship between the genders. C. No.
