The Effect: An Introduction to Research Design and Causality (Routledge, 2021) is about methods for using observational data to make causal inferences. It provides an extensive discussion of causality and the variety of both obvious and subtle challenges to inferring a causal relationship between the variables, using causal diagrams. It then goes through the major techniques that economists use to address these challenges, including regression, matching, simulation, fixed effects, event studies, differences-in-differences, instrumental variables, and regression discontinuity. The book is designed to be accessible to students or practitioners without the extensive math background that is taken for granted in typical econometrics textbooks. Instead, the emphasis is on the intuition behind the techniques and how to implement them with the widely-used programming languages R, Stata, and Python.Nick C.
