11. Suppose you are interested in estimating the effect of hours spent in an SAT preparation course (hours) on total SAT score (sat). The population is all college-bound high school seniors for a particular year. (i) Suppose you are given a grant to run a controlled experiment. Explain how you would structure the experiment in order to estimate the causal effect of hours on sat. (ii) Consider the more realistic case where students choose how much time to spend in...

Consider the model, Yi = Bo + B1 Xi + Uj, where you suspect Xi is endogenous. You have an exogenous instrument and you estimate the first stage to recover the residuals, Vhati. You want to test for endogeneity so you estimate the following model using OLS: Y; = Bo + B1 Xì + B2 Vhat; + Uj. The estimation results from 100 observations are in the table: Coefficient Standard Errors constant 2.96 0.47 X 0.75 0.85 Vhat 0.37 0.15...

Suppose you are interested in estimating how health affects
productivity. Specifically, you are interested in the following
regression:
where Yi is a variable representing the income earned by person
i, and Xi is a variable representing the health of person i.
Income is a fairly straightforward concept to capture. Health,
however, is a more complex concept that can be measured in many
different ways. For example, body mass index (BMI - weight in
kilograms, divided by height in meters squared)...

Consider the following slope estimator: b=2i=1 Yi Suppose the true model is ki + Bo + Bicite and the model satisfies the Gauss-Markov conditions. Answer the following questions: (a) What assumption in addition to the Gauss-Markov assumptions is required to estimate the model? (b) Show that in general, b is a biased estimator of B1. (c) Outline the special condition(s) under which b is an unbiased estimator of B1.

Suppose you are interested in estimating the effects of a the minimum wage increase in New Jersey in 1993. You observe employment levels at restaurants in New Jersey before and after the wage increase, and you also observe employment levels in Pennsylvania (which did not increase their minimum wage) before and after the wage increase. You estimate the equation emp = Bo + B, DnJ + B2 D post + B3 Dn.JDpost + u post is a dummy variable equal...

Suppose you are interested in studying the factors that influence wages. You plan on using a multiple regression model with k = 3 explanatory variables. In particular, you plan on estimating: wage = Bo + Bieduc + Bzexper+Bz age where wage = hourly wage in dollars educ = years of education exper = years of work experience age = age, in years An alternative way of estimating Ba would be to regress wage on re , (wage; = Bo +...
