Let Y be annual salary (salary) in thousands of dollars, and X be the average return on equity (roe) for the CEO’s firm for the previous three years. Return on equity is defined to be net income as a percentage of common equity. If roe = 5, than the average return on equity is 5%.

a. We are interested in investigating the relationship between roe, a measure of a firm’s performance and CEO compensation. To do this regress salary on roe and present the results of the regression in the form of an equation. State other relevant output that you obtained from running this regression below the equation, and be sure to summarize your results. You should also include the relevant output of the software you used to estimate your regression.

Based on your results in Part A:

b. Is the estimated intercept coefficient significantly different from 0? State the null and alternative hypothesis you are testing and conduct the hypothesis test at the α = 0.01 level. Explain your work.

c. One might hypothesize that the slope should be greater than 0. Set up a null and alternative hypothesis and conduct a hypothesis test with respect to this statement. Use a 5% level of significance. Explain your work.

d. Discuss the meaning of the slope parameter. That is, what does the slope parameter measure, and how is the predicted value of the dependent variable affected by a 1 unit change in the independent variable?

e. Using the Jargue – Bera (JB) test, determine if the error terms (or disturbances) are normally distributed? Be sure to include the test statistic and the p – value in your answer. Explain your work.

f. Suppose the roe = 30. What salary would you predict for the CEO of this firm? (remember that salary is given in 000s)

Solutions

Expert Solution

Answering first four parts:

a) for the relationship between roe and ceo compensation, salary is regressed on roe. It is done using R software.

salary= (alpha) + (beta)roe + error

Intercept coefficient obtained in this case is 963.2

slope coefficient: 18.5
