Geoffrey T. Wodtke and Xiang Zhou's Causal Mediation Analysis offer a comprehensive yet accessible guide to causal mediation analysis for social scientists. They explore why an exposure affects an outcome by quantifying the processes and mechanisms through which a causal effect operates. Covering everything from traditional methods through machine learning techniques and experimental designs for analysing mediation, the authors make these methods broadly accessible through clear explanations, practical examples, and the inclusion of extensive Stata and R code, allowing readers to replicate all the empirical illustrations and apply the methods directly to their own data. Starting with methods for intuitive, simple settings, they build up to more complex analyses, ensuring a smooth learning experience. Rich in examples from across sociology, psychology, political science, and economics, the authors demonstrate the application of cutting-edge methods to real-world empirical research, providing practical tools and examples for rigorous empirical research across disciplines.
