Threats and Analysis

In the following video Don Greene illustrates some of the challenges that can occur while conducting a randomized evaluation and how researchers handle these challenges. He  uses two case studies to show how to analyze and interpret the results from a randomized evaluation in the presence of various threats to analysis, such as attrition and non-compliance.

I will summarize the main ideas of this lecture and I will asnwer your questions.

After that you will have time to work online with your group. See below.


Group Work: Data analysis Plan (go to Activity)

Explain how you want to test the efficacy of your intervention: output measure, number of treatments, sample size, predictions and statistical analysis you intend to use.

Explain also how you plan to measure the necessary variables and how you want to gather your data.

Have in mind that testing behavioral interventions is the key step. Good policy design should use more pilots and trials to test if the intervention is working and to prevent the implementation of costly policies without generating results.

Together with your group, you have to fill the corresponding cell of this Google Spreadsheet. Deadline: before next lecture.
