Course outline

The aim of this course is to familiarize students with the use of some cross-sectional modeling techniques, primarily, to tackle endogeneity and interdependent data as well as non-i.i.d. disturbances. Most of the lecture will take these techniques to the case of panel data with a repeated observation of cross-sectional units over time.

The exam will be a term paper, written in groups of 2-3 people. The subject of the paper can be coordinated during the course.

Schedule

13 February 2017:  9:00-12:00
14 February 2017:  9:00-12:00 and 14:00-17:00
15 February 2017:  9:00-12:00 and 14:00-17:00
16 February 2017:  9:00-12:00 and 14:00-17:00
17 February 2017:  9:00-12:00

Additionally, we invite you to attend the presentation of Peter Egger in our research seminar on February 13, 2017, 14:15–15:45.

CROSS-SECTION MODELS

1. Review of OLS for single equations

a. with i.i.d. errors;
b. under heteroskedasticity;
c. with spatial autocorrelation in the disturbances;
d. seemingly unrelated regressions.

2. Endogeneity

a. with a single outcome equation (two-stage least squares);
b. with a system of equations (three-stage least squares);
c. with a spatial lag of the dependent variable.

3. Models for systematically missing data as a special case of endogeneity

a. sample selection;
b. treatment selection.

PANEL-DATA MODELS

1. One-way panel data models with exogenous regressors and homoskedastic error components:

a. fixed-effects models using least-squares dummy-variable estimates versus within estimates by least squares;
b. random-effects estimation with generalized least squares;
c. testing for fixed effects and random effects;
d. testing of fixed effects against random effects.

2. Two-way and multi-way panel data models with exogenous regressors and homoskedastic error components:

a. fixed-effects models using least-squares dummy-variable estimates versus within estimates by least squares;
b. random-effects estimation with generalized least squares;
c. mixed fixed and random effects models.

3. One-way panel data models with exogenous regressors and non-i.i.d. error components:

a. heteroskedasticity;
b. serial correlation in the disturbances;
c. spatial autocorrelation in the disturbances;
d. seemingly unrelated regressions.

4. Endogeneity

a. with a single outcome equation (two-stage least squares for fixed effects and two-stage generalized least squares for random effects);
b. with a system of equations (three-stage least squares);
c. with a spatial lag of the dependent variable;
d. with a time lag of the dependent variable (dynamic panels).

5. Models for missing panel data as a special case of endogeneity

a. Randomly missing data;
b. sample selection;
c. treatment selection.
