The integration of Datastream and Worldscope databases at the Wharton Research Data Services (WRDS) offers researchers a simple solution to bypass the cumbersome data collection and preparation process for global empirical research. This study guide proposes a clean approach to link these two databases through Refinitiv's Quantitative Mapping facilities. We then discuss various details about constructing stock returns through Datastream Return Index (RI). Finally, we demonstrate through an empirical case study on how to combine Datastream's pricing data and Worldscope's fundamental data to compare market characteristics across countries.
