The Effect: An Introduction to Research Design and Causality

Finally... a book that covers good research design AND the key methods to answer causal questions AND nice code examples!The author does an excellent job walking the reader through the research process in a practical and very accessible way. I couldn't put this book down!I'm an experienced quantitative researcher and will be recommending this to colleagues (and using as teaching resource!).

This book has mastered how to make a book about causal analysis entertaining to read for a wide audience. A one in a lifetime masterpiece!

Easily the best written introduction to causal inference out there

It's a really great intro to causal thinking that is far more approachable than your standard econometrics textbook

Seems like a very well-written book, but arrived damaged, almost like it was dropped at some point during packing. In addition, the printing is sometimes poor, with the ink fading slightly towards the bottom of the page. In many cases the margins are off - there is almost an inch of white space for the footer consistently and less than a quarter of an inch for the footer at times. It seems like they tried to just offer a quick print for the sake of a print version being offered.Just use the online version and save your money.

Nick did a terrific job in explaining complex concepts in a very accessible way. A skill any writer would kill to have.

Useful for any level of students in Economics, Statistics, Data science,etc.You have recent causal inference explanation in a easy manger for reader.This is the best introductory causal inference book to date in my point of view.I prefer buy the book over the free website and I like it.The white space in the book allow to take notes during reading.

My education in economics had a big lacuna in that I never really understood any of the econometrics that my Professors threw at us in class. I always thought the problem is at my end - may be I have some sort of disability that I am unable to comprehend it. After reading Nick's book, I have updated my beliefs. The problem wasn't with me. It was at the other end. This book is terrific. Teaches you how to think econometrics intuitively.

I am using this book regularly now in classrooms. It has a really easy-to-comprehend text, great examples, and code in multiple languages. Highly recommended for all levels!

I am half-way through this book (will update this review once I complete it). So far I have been very impressed with Nick's writing style. New concepts are introduced in an incredibly accessible manner, it makes them feel intuitive and natural. A large part of this (I think) is because he avoids excessive jargon and heavy reliance on mathematical proofs without first explaining the concepts behind the formulae.I have also been impressed with the sheer amount of humour packed into this textbook - it really helps to lighten what can typically be a heavy topic.Thanks for sharing your knowledge with the world, Nick!
