One is interested in the ceteris paribus relationship between the dependent variable y; and the explanatory variable ₁1. For this, one collects data on two control variables 2 and 3 and runs two LS regressions. Regression 1: yi = Buil+ui Regression 2: yi = B1x1 + B₂x2 + 3x i3 + Ei Let B₁ denote the LS estimate of ₁ of Regression 1 and let ₁ denote the LS estimate of ₁ in Regression 2. Assume that the true model is given by Regression 2 and that all variables are centered. b) would you expect a difference between ₁ and 3₁ when ₁₁ has almost no correlation with Xi2 and and 3 are highly correlated? but 2 Xiz a) Would you expect a difference between ₁ and ₁ when ₁₁ is highly correlated with 2 and 3 and the partial effects of xi2 and is on y, are also high?
