This lecture provides a rigorous, step-by-step demonstration of how to extract macroeconomic data from the World Bank’s World Development Indicators (WDI) database and operationalize it within EViews for empirical analysis. The session begins with a structured approach to selecting relevant indicators, countries, and time horizons, ensuring consistency and comparability in cross-country datasets. The tutorial then transitions to data handling—covering file formats, variable structuring, and efficient import techniques into EViews. Particular emphasis is placed on diagnosing data integrity issues such as missing values, frequency mismatches, and transformation requirements (e.g., logarithmic scaling, differencing). A core contribution of this video is the methodological treatment of data structure conversion: transforming raw time series into panel data format. This includes a conceptual explanation of panel data econometrics—highlighting cross-sectional and temporal dimensions—followed by practical implementation in EViews, including workfile structuring, indexing, and panel specification. Finally, the lecture develops an analytical framework for interpreting the dataset, focusing on economic meaning rather than mechanical output. It discusses how variable behavior reflects underlying macroeconomic dynamics, enabling viewers to bridge the gap between data processing and econometric modeling. This video is particularly valuable for researchers, graduate students, and practitioners engaged in applied econometrics, development economics, and empirical policy analysis.
