In this exercise we examine which factors might influence the wages of employees. To do so, the variable wage is regressed on the variables educ, tenure, tensq, female, married, and m_female.Table 1: Descriptive StatisticsVariable Explanationwage Average hourly wage (in €)educ Years of educationtenure Employment duration (current employer)tensq = tenure × tenurefemale dummy (= 1 if female)married dummy (= 1 if married)m_female      Interaction term (= married × female)The corresponding Stata output is:Source | SS df MS N. of obs. = 526 + F(6, 519) = 57.23 Model | 2851.181 6 475.197 Prob > F = 0.000 Residual | 4309.233 519 8.303 R-squared = 0.398 + Adj.

You are interested in the influence of education on hourly wages.Table 1: Description of VariablesVariable Descriptionwage Hourly wage (in €)educ Education in yearsSelect the population model with which the interpretation below is possible.The hourly wage of a person increases by x € if the education of the person increases by one percent (ceteris paribus).Answer 1Answer 2Answer 3Answer 4

Human capital theory suggests that those who have invested in higher levels of education will be able to command higher wages. A labour economist collected data on annual wages (Y, in $'000) and years of study (X) from a random sample of 12 employees to test this proposition. Assuming a linear relationship between Y and X, the labour economist used a least-squares method and found that the Y intercept = -23.50 and the slope = 9.73. Also, the sum of squares total (SST) and the sum of squares regression (SSR) were equal to 11132.92 and 8726.91, respectively. What is the lower bound of a 95% prediction interval of annual wages (in $'000) for an employee with 10 years of study. Assumer the h Statistic is 0.10. a. greater than $20 but less than $36 b. less than $20 c. greater than $20 but less than $30 d. greater than $36

Human capital theory suggests that those who have invested in higher levels of education will be able to command higher wages. A labour economist collected data on annual wages (Y, in $'000) and years of study (X) from a random sample of 12 employees to test this proposition. Assuming a linear relationship between Y and X, the labour economist used a least-squares method and found that the Y intercept = -23.50 and the slope = 9.73. Also, the sum of squares total (SST) and the error sum of squares (SSE) were equal to 11132.92 and 2406,01, respectively. Based on this information, we can say that a. around 21.61% of the variation in Y is explained by the variation in X. b. around 21.61% of the sample variability in Y is due to factors other than X c. around 78.39% of the sample variability in Y is due to factors other than X d. around 21.61% of the variation in X is explained by the variation in Y.

A pattern in the coefficients of the time fixed effects binary variables may reveal the following in a study of the determinants of total factor productivity growth using panel data: a. total factor productivity shocks for particular entities in the panel. b. total factor productivity shocks for individual entities. c. there is no economic information that can be retrieved from these coefficients. d. An increase in total factor productivity that benefits all entities equally in a given year. e. All of the above. f. None of the above.
