This PhD elective subject gives the basis necessary for PhD candidates to analyze business and economic data in an empirical manner. The subject deals with an advanced level of econometric principles and tools for cross-sectional, panel and time-series data sets. While concentrating on linear models, some non-linear cases are also discussed: in particular, limited dependent variable models and generalized methods of moments. A series of modern econometric techniques are discussed, having put an emphasis on fundamental econometric thinking by interweaving theoretical cases with application of micro- and macro-economics using software. Successful completion of PHD210 - Statistics for Social Sciences is a prerequisite for this subject.
