Swedish schools that implemented a cell phone ban so no resulting change in grades or national math test scores of their students (N = 16,724). Maybe, just maybe, we need to stop blaming technology all the time from econstor.eu/bitstream/1041…
Related to this, there’s a great AER paper by and Kindermann “Bargaining over Babies.” Both partners have to agree to have another child. And in survey data, women are more likely than men to be opposed to another child! Esp for 3rd+ kid. faculty.wcas.northwestern.edu/~mdo738/resear…

The key long-term human trend may be the Demographic Transition: at a GDP/person of between $1.8k-$3k, mortality & fertility rates drop. Out of 186 countries: 🪦All started & 175 finished the mortality transition 👶All (but Chad) started & 80 finished the fertility transition
