References

Each chapter lists the works it cites at the bottom of its own page; the complete bibliography lives in references.bib in the book repository. The list below is deliberately wider than the set of works cited in the text: it prints every entry in the bibliography, so it doubles as further reading. A work appearing here is therefore not evidence that a particular claim in the book rests on it — for that, follow the citations in the chapters themselves. The main background references are Imbens and Rubin (2015) and Hernán and Robins (2020).
