Hey #EconTwitter: For the first time in 20 years, I am not spending my first week of January at the @ASSAMeeting. It's a weird feeling; I've always enjoyed showing off new books, connecting with friends, and talking with economists about new ideas 1/25

As with so much else, #ASSA2021 will be a new (hopefully one-off) experience; and even though I'm not standing by a booth in a sub-basement of the Hyatt Regency Chicago, I'd like to introduce you to some recent and forthcoming books in #economics from @yalepress 2/25

First up is CAUSAL INFERENCE: THE MIXTAPE by @causalinf. The short description is that this is a toolkit for economists and other social scientists to untangle cause and effect, but this book is so much more than that 3/25

It is a labor of love by @causalinf; a guide through one of the most important ideas in economics; and an indispensable "second book" for any econometrics course. It is also the only book you'll ever see that has been endorsed by both @JustinWolfers and @officialyoungmc 4/25

If you've used the online version of the Mixtape in the past, this edition is wholly revised and expanded, with coding for both R and Stata. An HTML version will be accessible at https://t.co/QSvOJb0HSG. You'll want the physical book as well; they are complementary goods 5/25
