The coefficient on treatment in the regression would be
which is the
slope differential .i.e. when treatment dummy is 1 the slope is
compared to when the treatment dummy takes value zero; the slope
is
.
Question 7 1 pts You could also estimate a regression with arrest likelihood as an outcome...
Intepret the SATE and the coefficient estimate on treat. Discuss the use of linear regression in experimental research designs. What is the relationship between β and the Sample Average Treatment Effect (SATE)? When would one use regression over the SATE?
Question 4 5 pts A researcher studies the causal effect of education on earnings for male adults using data from a random sample of U.S. adult male workers. She plans to regress individual male workers' earnings (Y) on the number of years of education (X1) the workers have, controlling for work experience and other characteristics of the individuals (Z, e.g. experience). Assume that the unemployment rate is low and the unemployment distribution is random. The researcher is worried that the...

1. Which of the following conditions will lead to a smaller variance for the intercept estimator for your multiple regression model? (A) X values cluster far from the origin of the X axis (B) X values closely pack around the mean of X in your sample (C) Small sample sizes (D) High correlation among the explanatory variables (E) Small error variance in the population regression function 2. R-squared (A) measures the proportion of variability of the dependent variable that is...

Suppose you are interested in estimating how health affects productivity. Specifically, you are interested in the following regression: where Y, is a variable representing the income earned by person i, and X, 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) is...
1.You are interested in estimating the effects of owning a tablet (such as an iPad) on the grades of high school students (the idea is that owning a tablet might help students take notes and study more effectively). You have data on tablet ownership and GPA for a sample of 1000 students. You wish to estimate this model: GPA=B0+B1tablet+u where GPA is the student's grade point average measured on a scale of 0-4, and tablet is a dummy variable that...
