Economic Experiments & Impact Evaluation

Course Description

A key challenge in public policy is determining whether policies and interventions have a measurable impact on living standards and measures of well-being. What are the impacts of programs and initiatives that have been implemented, or at least piloted on a small scale? For example, the impact of conditional cash transfers on education, health and well-being of children, or the impact of financial literacy training on the ability of households to manage their finances? Over the past decade, a large literature has emerged to attempt to answer these important questions.

This course exposes the students to key concepts and quantitative tools in impact evaluation. It will draw examples from studies and evaluations that have been conducted around the world in recent years. It will introduce students to experimental and quasi-experimental approaches that have been used in impact evaluation. Students will use Stata to analyze microeconomic data and apply various quantitative approaches. The empirical exercises include both in-class exercises and problem sets.

Specific Learning Goals

  1. Clear understanding of causal identification: what it is, what it isn’t, and why it matters

  2. How to achieve causal identification: what are the key methods and how to apply them.

    1. Including both experimental and quasi-experimental approaches

    2. Including familiarity with recent examples of applications

    3. Including hands-on skills in applying each method using Stata

  3. What are the pros and cons of each method: what are the data requirements, what are the underlying assumptions, under which conditions are the assumptions reasonable, which is the best method for a given context?
