![2. Assume the structural equation is where E [ui|Xi] = 0. It was discovered that we observe ri with a measurement error wi instead of the real value X X-Xi + w It is known that E [wi-0, V (wi) %-cou (Xi, wi)-cov is based on regressing Y, on a constant and X. (u,,wi) 0. The OLS estimator (i) Find the value to which the OLS estimator of β¡ is consistent for. (ii) Is the value equal to the true value β? If not, how is the bias related to the true value? (iii) Assume we have a consistent estimator for σ. How would you make a correction to consistently estimate β? (iv) Discuss other potential solutions when such estimator in (ii) is not available 3, Exercise #9.7 (Stock and Watson)](http://img.homeworklib.com/questions/819f7d10-72fa-11ea-9e15-89dc717d9186.png?x-oss-process=image/resize,w_560)

Consider the linear probability model Yi = β0 + β1Xi + ui. Assume E(ui|Xi)=0. Which of the following statements are true? Question 5 options: The predicted value of the dependent variable can be greater than 1 or less than 0. Thus, the OLS estimator of β1 is biased. The predicted value of the dependent variable will always be between 0 and 1. Thus, the OLS estimator of β1 is unbiased. The predicted value of the dependent variable will always be...
