Textbook Question
Chapter 14, Problem 14P
The additive weighting model is a decision tool that aggregates information from different independent criteria to arrive at an overall score for each course of action being evaluated. The alternative with the highest score is preferred.
The general form of the model is
where
Vj = the score of the jth alternative;
ωi = the weight assigned to the ith decision attribute (1 ≤ i ≤ n);
xij = the rating assigned to the ith attribute, which reflects the performance of alternative j relative to maximum attainment of the attribute.
Consider Table P14-14 (p. 597) in view of these definitions and determine the value of each “?” shown. (14.7)

Using data from 1988 for houses sold in Andover, Massachusetts, from Kiel and McClain
(1995), the following equation relates housing price (price) to the distance from a recently
built garbage incinerator (dist):
=
log(price) 9.40 + 0.312 log(dist)
n = 135, R2 = 0.162.
Interpretation of the slope coefficient?
► How would our interpretation of the slope coefficient change if
distance were measured in metres instead of kilometres?

- 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
