Thread on our survey on "A New Era in the Economics of Fertility." Why a new era? Because everything has changed! - The empirical regularities of fertility choice have reverted. - The mechanisms emphasized by earlier research have lost relevance. 1/12
New fact #1: - Fertility used to be decreasing in income. - Now, among high-income countries, richer countries have higher fertility rates. 2/12
New fact #2: - Fertility used to be decreasing in women's labor force participation. - Now, among high-income countries, countries where more women work have higher fertility rates. 3/12
Across 70+ RCTs run by with US cities, we find that 27% of treatments are adopted by the gov. agency (you guessed 32%). But wait, there's more. What predicts adoption? Strength of evidence? Not really. Staff retention? Less important than we thought. (2/n)

Econ needs a shorter publishing process. As a referee, don't push authors to do every possible robustness test to show their story is the only plausible one. Encourage them to be more explicit on their limitations. We need more refinement across papers and less within papers.
Forthcoming in the JEL: "Publishing Economics: How Slow? Why Slow? Is Slow Productive? How to Fix Slow?" by Aboozar Hadavand, Daniel S. Hamermesh, and Wesley W. Wilson.
