Question 3

If data is missing for completely random reasons (i.e., not related to X or Y), then this leads to:

Question 3 options:

A bias in the OLS estimator.

A reduction in sample size.

An increase in the variance of the OLS estimator.

Both (b) and (c).

Question 4

Consider the linear probability model Yi = β0 + β1Xi + ui. Assume E(ui|Xi)=0. Which of the following statements are true?

Question 4 options:

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 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 biased.

The predicted value of the dependent variable can be greater than 1 or less than 0. This does not mean the OLS estimator of β1 is biased.

    It is easy to construct a case that the US spends way too much money on health care. The US spends twice as much as the average OECD country, 90% more than the Canada and 150% more than the UK, yet the US has one of the lowest life expectancy rates and one of the highest infant mortality rates in the developed world. Some have suggested these numbers indicate that at the margin, additional health care dollars generate little in...
