QUESTION 2 The generalized least square estimators for correcting heteroskedasticity are called weighed least squares estimators. True False QUESTION 3 One of the assumptions for the plug-in solution to provide consistent estimators of $\beta_1$ and $\beta_2$ is that the error u is uncorrelated with all the independent variables. True False QUESTION 4 Refer to the following model $y_t = \alpha_0 + \beta_1 x_{t} + \beta_2 x_{t-1} + \beta_3 x_{t-2} + \beta_4 x_{t-3} + u_t$ Given a permanent increase in 5, $\beta_3$ is the long-run propensity. True False QUESTION 5 An explanatory variable is called exogenous if it is correlated with the error term. True False

Q1. [40 points] (Measurement Error Bias) Consider Y = α + βX + u and it satisfies all the least squares assumptions. Suppose that X is measured with error, so we observe x̃ = X + w. w is the measurement errors which are i.i.d. and independent of u and X. Thus, our regression equation is Y = α + βx̃ + ε, where ε is the regression error using the mismeasured independent variable x̃. 1.1 [20 points] Show that when the OLS estimator β̂ using (2) is biased and inconsistent. Please show the whole process of the math proof to receive the full credits. Under what conditions the OLS estimator would be consistent? 1.2 [20 points] Assuming now, X is measured without error, instead Y is measured with error, i.e. ȳ̃ = Y + v. v is the measurement error which are i.i.d. and and independent of u and X. (a). (5 points) Write the new regression equation (b). (10 points) Is the OLS estimator β̂ using the new regression equation in part (a) unbiased? Prove your result. (c). (5 points) Is the OLS estimator β̂ using the new regression equation in part (a) consistent? Prove your result.

How many of the following statements are true? (I) In least squares regression, the sum of residuals is always equal to zero. (II) The least squares regression line minimizes the sum of squared residuals. (III) A residual plot that displays a random scatter of points is a good indication that the assumptions in the simple linear regression model are valid. (IV) One assumption in the simple linear regression model is that the standard deviation of Y is constant for all values of X. (V) One assumption in the simple linear regression model is that Y follows a normal distribution for all values of X.
