eComm and D2C will be acutely impaired by the ATT opt-in mechanic coming to iOS (rumored made mandatory in March). ATT doesnt exclusively impact app advertisers, & in fact may disproportionately damage eComm and D2C. Some thoughts on how those advertisers should prepare (1/X)
2/ In the @MobileDevMemo 2020 mobile advertising predictions post, I posit that D2C ad spend may drop by as much as 50% in Q2 2020. FB revealed in December that app-to-web campaigns will be governed by ATT opt in, severely limiting campaign efficiency
3/ FB had only previously discussed ATT in terms of app campaign relevance. This new revelation likely stemmed from further instructions from Apple following FB's initial guidance
4/ FB affirmed in Dec that app-to-web campaigns will be: conversion event limited, aggregated at campaign level, and limited wrt attribution windows (default: 7-day click). This effectively replicates the privacy treatment of app campaigns on app-to-web campaigns
5/ Adam Lovallo from https://t.co/baV6VrUW7E describes 28-day click / 1-day view the "gold standard" for D2C. Why would FB change the default to 7-day? Because it is aggregating conversions at the campaign level -- universally, with what it is calling Aggregated Event Measurement

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
