Anotace
Students aiming for a career in central banks, academia or international institutions will learn methods that are necessary to understand, replicate and conduct empirical research in macroeconomics.
The first part of the course covers modelling univariate time series (stationary and nonstationary models, spectral analysis, regime-shift models). The second part of the semester is devoted to multivariate models, forecasting, and identification of causal relationships in macroeconomics. The recently developed approaches to identification such as external instruments in VAR or high frequency identification are covered as well.
Our course participants apply all covered methods in regular problem sets that are based on replications of academic papers. These problem sets are presented and discussed in the seminars.
Problem sets shall be prepared in R and delivered as Jupyter notebooks, sample R-codes are provided.
