QUESTIONS:
1. Create the relevant variables for the estimation of a Cobb-Douglass Production function:
lnQ = ln(Output)
lnL = ln(Employment)
lnK = ln(Capital)
2. Construct the sample mean, sample standard deviation, median for Output, Employment, and Capital. WRITE DOWN THESE STATISTICS
3. Run a linear regression of ln(Output) (dependent variable) on ln(Employment) and ln(Capital) as independent variables. For this part of the analysis you have to:
A. Is this coefficient significant? YES or NO, EXPLAIN
B. What effect does Employment have on Output? EXPLAIN
C. What coefficient indicates the effect of Capital on Output? WRITE THE VALUE HERE
D. Is this coefficient significant? YES or NO, EXPLAIN
E. What effect does Capital have on Output? EXPLAIN
F. What does the sum of the coefficients for Labor and Capital suggest about the type of returns to scale displayed by this production function?
G. Construct individual firms’ productivity. Which firm is the most productive? Which firm is the least productive?

A) second coefficient (lnL) is more significant than first as R squared is around 48% .
B) effect is positive. more the employment more is output as the coefficient is positive i.e. 0.6934
C) 0.5459
D) NO. R squared is very less.
E) effect is positive. more the capital more is the output as coefficient is positive i.e. 0.5459
