Practical application and scientific analysis in the field of economics increasingly rely on the use of empirical methods. This book introduces students of economics and related disciplines to the key methods of applied economic research, including econometrics. The content of the textbook covers areas such as data (foundation and preparation), economic indicators, input-output analysis, econometric procedures, trend and seasonal adjustment, as well as simulation and forecasting. Throughout, there is a strong emphasis on practical applications and an intuitive approach, without compromising on a formal presentation of the methods. The methods are explained in an easily understandable manner. Illustrative case studies and references to practice-relevant topics make the book particularly vivid and engaging for the reader.
