Benefit–cost ratio.

Explanation of Solution
Benefit (B) is $10,000 per year forever. Cost (C1) is $50,000 at year zero and (C2) $50,000 at the end of year (n) 2. Interest rate (i) is 10%.
Option (b):
The benefit–cost ratio (BC) can be calculated as follows:
The calculated BC value is nearly equal to the given value. Thus, option ‘b’ is correct.
Option (a):
The benefit–cost ratio (BC) can be calculated as follows:
The calculated BC value is greater than the given value. Thus, option ‘a’ is incorrect.
Option (c):
The benefit–cost ratio (BC) can be calculated as follows:
The calculated BC value is less than the given value. Thus, option ‘c’ is incorrect.
Option (d):
The benefit–cost ratio (BC) can be calculated as follows:
The calculated BC value is less than the given value. Thus, option ‘d’ is incorrect.

- CEO Salary and Firm SalesWe can estimate a constant elasticity model relating CEO salary to firm sales. The data set is the same one used in Example 2.3, except we now relate salary to sales. Let sales be annual firm sales, measured in millions of dollars. A constant elasticity model is[2.45]ßßlog (salary) = ß0 + ß0log (sales) + u,where ß1 is the elasticity of salary with respect to sales. This model falls under the simple regression model by defining the dependent variable to be y = log(salary) and the independent variable to be x = log1sales2. Estimating this equation by OLS gives[2.46]log (salary)^=4.822 + 0.257 (sales) n = 209, R2 = 0.211.The coefficient of log(sales) is the estimated elasticity of salary with respect to sales. It implies that a 1% increase in firm sales increases CEO salary by about 0.257%—the usual interpretation of an elasticity.arrow_forwardSolvearrow_forwardAsap please and give with explanation with each steparrow_forward
