Final Exam

The main purpose of the final exam is for students to estimate the impact of a real randomized control trial RCT. The randomized control trial you will examine provided information to first-time mothers living in poverty in Nashville TN. The information to first-time mothers was provided in books, called hereafter “Baby-Books.” Mothers in the intervention group received new baby-books every two-months. The hypotheses of this RCT were that the new information provided to mothers via “Baby-Books” would:

1. Improve parenting skills

2. Improve nutritional practices with their babies,

3. Prevent un-intentionally baby injuries.

4. Improve post-partum depression and stress levels

5. Impact labor participation

Overall, helping first-time young women to overcome the anxiety of becoming first time mothers’ should therefore, improve their own and their baby’s health in the short and long run.

Each student will estimate an intent to treat (ITT) and the treatment on the treated (TOT) effect of the randomized educational book intervention. To measure the effect of this intervention, first time mothers were randomly assigned to one of three groups: 1) an educational book group (the intervention), 2) a non-educational book group, or 3) a no book group. Participants were interviewed by either phone (12 times) or personal interviews (7 times).

On the interviews, participants self-reported all the outcomes of interest such as type and occurrence of their child’s unintentional injuries, knowledge learned by reading the given books, labor market outcomes, post-partum depression, stress, and many other important outcomes.

Each student in class will examine the impact of this randomized intervention on one or two outcomes of interest.

There will be five groups, each group should answer the following questions:

1. What is the intervention about? Explain the study design, sample size by group at baseline. Write down the results chain describing the inputs, activities, outputs, and outcomes of this intervention.  (10 points)

2. Did the intervention have a valid counterfactual? (10 points)

3. Estimate the outcomes of interest by subject, group, and time. (Suggestion: make sure you estimate the outcomes of interest at baseline and create fixed time intervals, following the baby’s age at 0, 6, 12 and 18 months old. Some outcomes were not asked at the exact desirable time intervals, but you can estimate the mean or sum of the outcomes at the nearest given time). (10 points)

a. Identify all the variables you will use in your analysis and create two final datasets: 1) A wide cross-sectional dataset including household demographics, outcome of interest, and time fixed variables. 2) A panel dataset. (10 points)

b. Estimate the impact of the intervention by using the following methods:

1. Pre-Post analysis, (10 points)

2. Randomized Assignment, (10 points)

3. Difference-In-Difference (10 points)

Explain and compare your results. For each estimation, explain whether the outcome improved or got worse? Interpret the results

4. What characteristics (mother’s or babies) correlate with the outcome of interest? For instance, were children’s injuries a function of their own developmental growth (i.e. increasing as children grow older), children’s gender (i.e. do boys have more injuries than girls?), mother’s education? mother’s income. (5 points)

5. Estimate the TOT intervention effect by using a Randomized Assignment and a DID methodology. Explain and compare your results with previous ITT. (10 points)

Data and Documentation: All questionnaires use to gather the information, dataset, and codebooks are available on BrightSpace.
