Q: Results of a study by McClelan, McNeill, and Newhouse are

Results of a study by McClelan, McNeill, and Newhouse are reported. They estimate the effect of cardiac catheterization on patient survival times. They instrument the use of cardiac catheterization by...

Q: Consider the potential outcomes framework. Suppose Xi is a binary treatment

Consider the potential outcomes framework. Suppose Xi is a binary treatment that is independent of the potential outcomes Yi (1) and Yi (0). Let TEi = Yi (1) – Yi (0) denotes the treatment effect for...

Q: For the following calculations, use the results in column (3

For the following calculations, use the results in column (3) of Table 13.2. Consider two classrooms, A and B, which have identical values of the regressors in column (3) of Table 13.2, except that: a...

Q: Suppose that, in a randomized controlled experiment of the effect of

Suppose that, in a randomized controlled experiment of the effect of an SAT preparatory course on SAT scores, the following results are reported: a. Estimate the average treatment effect on test score...

Q: A new law will increase minimum wages in City A next year

A new law will increase minimum wages in City A next year but not in City B, a city much like City A. You collect employment data from a random selected sample of restaurants in cities A and B this ye...

Q: Consider a study to evaluate the effect on college student grades of

Consider a study to evaluate the effect on college student grades of dorm room Internet connections. In a large dorm, half the rooms are randomly wired for high-speed Internet connections (the treatme...

Q: Suppose there are panel data for T = 2 time periods for

Suppose there are panel data for T = 2 time periods for a randomized controlled experiment, where the first observation (t = 1) is taken before the experiment and the second observation (t = 2) is for...

Q: Suppose you have panel data from an experiment with T = 2

Suppose you have panel data from an experiment with T = 2 periods (so t = 1, 2). Consider the panel data regression model with fixed individual and time effects and individual characteristics Wi that...

Q: Yi, i = 1, …, n, are i.

Yi, i = 1, …, n, are i.i.d. Bernoulli random variables with p = 0.6. Let Y denote the sample mean. a. Use the central limit theorem to compute approximations for i. Pr (Y >= 0.64) when n = 50. ii. P...

Q: Suppose you have the same data as in Exercise 13.7

Suppose you have the same data as in Exercise 13.7 (panel data with two periods, n observations), but ignore the W regressor. Consider the alternative regression model where Gi = 1 if the individual i...
