Short Answer

SCENARIO 13-13
An econometrician is interested in evaluating the relationship of demand for building materials to mortgage rates in Los Angeles and San Francisco.He believes that the appropriate model is $$Y = 10 + 5 X _ { 1 } + 8 X _ { 2 }$$
where
$$\begin{array} { l } X _ { 1 } = \text { mortgage rate in } \% \\X _ { 2 } = 1 \text { if SF, } 0 \text { if LA } \\Y = \text { demand in } \$ 100 \text { per capita }\end{array}$$
-Referring to SCENARIO 13-13, holding constant the effect of city, each additional increase of1% in the mortgage rate would lead to an estimated increase of in the mean demand.
