Course Prerequisite: ECO 416 or equivalent.
Course Requirements: Students are expected to read assigned readings and attend all lectures
because some class materials will not be in the readings. There will be 10 problem sets, most of
which require using Stata. Feel free to work cooperatively. However, each student must turn in
his or her own problem set using his or her own words and interpretation of the results. Late
problem sets will not be accepted.
Course Grading: (1) problem sets: 75%; (2) class participation: 5%; and (3) …nal exam (takehome): 20%. Problem sets will be graded using a 0–5 ordinal scale: 5 = excellent; 1 = poor;
and 0 = not handed in.
Course Overview and Objectives
In most of economics we are interested in causal, rather than correlative, relations among variables.
For example, it is not the correlation between earnings and years of schooling that is of interest, but
the e¤ect of increasing someone’s schooling by one year on that same person’s earnings. Microeconometrics focuses on identifying such a causal relationship using cross-sectional or short panel data.
It is very often that the heterogeneity of economic relations across individuals, …rms and industries
confounds correlations with causal relations. This course aims to: (1) familiarize students with conditions which are required for credible inference for causal e¤ects; and (2) enable students to select

appropriate econometric tools for empirical economics problems and policy research. Topics include
robust inference, numerical optimization, instrumental variables, nonparametric regression methods,
treatment e¤ect analysis, and panel data.
By the end of the course, students should (1) be able to model the source of heterogeneities
according to the characteristics of micro-level data; (2) be familiar with approaches to causal inference
using the potential outcomes framework; and (3) have a …rm grasp of types of research designs that
enable researchers to evaluate the credibility of the empirical evidence used for testing theories and
for evaluating policies.
