An engaging and practical introduction to econometrics, Real Econometrics: The Right Tools to Answer Important Questions, offers thorough coverage of the most frequently used methods of analysis. Grounded in contemporary understandings of causal inference, the text invites students to extract meaningful information about important economic policy issues from available data. Bailey's emphasis on practical applications, combined with a lively and
conversational narrative and a diverse array of examples and case studies, provides students with a solid foundation in the analytical tools they will use throughout their academic and professional careers. The second edition includes new conceptual exercises, revised appendices, and additional code and guidance for R
software.
Bailey has written an excellent and unique text that can serve students in a wide range of fields-not just economics-as well as practitioners who need a refresher or an introduction to more advanced methods. The conversational style and emphasis on motivation and intuition over mathematical detail, together with engaging examples and case studies, make this text highly accessible and a pleasure to read."
