### Course Syllabus

#### Abstract

The course “Advanced Econometrics” focuses on the estimation, inference and identification of regression models. Particular attention is paid to the econometric theory, to the application of econometrics to real-world problems, and to the interpretation of the estimation results. The first part of the course (Fall term) includes linear regressions and models with limited dependent data. Topics on Gauss-Markov theorem, endogeneity, instrumental variables, maximum likelihood estimation will be covered. The second part of the course (Spring term) is focused on issues in system of equations; time series models; panel data models; nonparametric and semiparametric models; Bayesian estimation. The course will include the use of STATA and MS Excel. Use of R and other statistical analysis software is optional.
