The project aims to enhance and improve the Mathematical and Statistical Methods in Economics study programme, particularly emphasising its internationalisation. The primary objective is to convert three fundamental courses (Bayesian analysis, Econometrics, and Macroeconomic modelling) into English and enhance their content, structure and used teaching methods to align with the current trends in the corresponding areas. The project focuses on improving the excellence of the curriculum at the level of courses and facilitating the involvement of foreign academics in teaching to bring new expertise to the programme.
