Suppose y is determined by the true model y=β0+β1x+β2z+ε, and that β2 >0 and COV(z,x) < 0. If someone were interested in estimating β1, and did so by using OLS to estimate y = β0 + β1x + u, would the OLS estimator of β1 be biased or not? If it is unbiased, explain why. If it is biased, is the bias positive or negative? Why?

Model: Y = β0 + β1X + u If E(u|X) 6= 0, then we know the OLS estimator will be biased and all further inference like Hypothesis test and Confidence interval will be invalid. In presence of such violation, we can go to Instrument variable estimation/regression method to rebuild the valid empirical study. Assume there is a “good” instrument variable Z for X. (1) How would you argue this is a valid instrument variable?(Hint: validity condition and relevance condition) (2)...

8. Calculating SSR, SSE, SST, and R-squared Suppose you are interested in studying the effects of education on wages. You gather four data points and use ordinary least squares (OLS) to estimate the following simple linear model: wage=β0+β1educ+u where wage = hourly wage in dollars educ = years of formal education After running your regression, you decide to examine how the fitted values of wages from your regression compare to the actual wages in your data set. These data are...
