🚨Replication alert🚨
I'm pleased to announce that my replication of Moretti (2021) is now accepted as a comment at AER.

I find ten issues in the paper. My comment focuses on two major problems; in the appendix, I document eight (relatively) minor problems.

Does anyone have a clean way to go from rdrobust to modelsummary? I just want to make some vanilla RD tables. Is this from @vincentab.bsky.social 6 years ago still state of the art? #rstats

The First 1,000 Days and Beyond: The Process of Child Development (Forthcoming Article) - This paper reviews recent research in the economics of human development, focusing on the early years of life as a critical period for shaping long-term outcomes. Early childhood development is inherently multidimensional: cognitive and socioemotional skills evolve dynamically and interact with health, nutritional, and environmental influences. Economists have contributed to this field by providing a conceptual and unifying framework that highlights how key drivers of development reflect the choices of individuals operating under both incentives and constraints. The paper emphasizes two central challenges: understanding the interactions among multiple dimensions of development and identifying causal links, particularly the effects of different inputs at different ages. Measurement issues are a recurring theme, given the difficulty of assessing young children and the need for comparability across contexts. By discussing early childhood interventions in both developed and developing countries, the paper also stresses these issues’ policy relevance for poverty reduction and social mobility.

Wenn das Teilen deiner eigenen Interviews als Schmutzkampagne taugt, liegt das Problem möglicherweise nicht bei deinem politischen Gegner.

Good interview. 👇🏼

@andreasloeschel.bsky.social points out that the current discussion of solar panel subsidies in 🇩🇪 is far less problematic than the weakening of support for CO2 prices (including emmission trading). And he, too, pushes for reducing fossile fuel imports.

Europe Must Not Abandon Its Climate Ambitions Catherine Wolfram highlights three recent developments that underscore why the bloc should maintain its carbon-pricing system.

I'm pleased to share my recent column in Project Syndicate.

⚙️ I argue that we can think of Europe’s climate leadership as a policy flywheel.

Event-study plots in DiD are incredibly persuasive—but, honestly, not always honest.

Why?
If parallel trends or no anticipation fail, DiD estimates are biased. Testing against a zero-effect null then becomes misleading.

Parents’ traits can bias reports of children’s non-cognitive skills. Using parent and teacher measures of child skills in a dynamic model, we show that this bias tends to mask maternal influence and can distort evaluations of childhood interventions. buff.ly/H8Oi42O

Well worth a watch!

Mein Mitgefühl gilt zB den Kolleg:innen aus Bosnien, die vor dem Krieg nach Ö flüchteten, hier seit Jahrzehnten als Leistungsträger:innen in Pflege, Spitälern, Handel oder Industrie arbeiten, Steuern zahlen, ihre Kinder großziehen und dann so etwas lesen müssen. Entschuldigung! Wir sind nicht so.

For someone who grew up in (the top decile of the income distribution of) a developing country, it is hilarious to see what Americans think is the bare minimum for a middle-class life. Kids sharing a bedroom? Oh, the indignity…

This looks like a must-read for diff-in-diffs folks.

Our "Dodging Day Zero" paper is out in JEEA. We uncover how Cape Town avoided 2017's catastrophic drought. But in doing so, created longer term sustainability challenges and weakened the fiscal viability of public water. A lesson for the 1B living in drought vulnerable cities.

Households face annual costs of roughly $400–$900 from climate change—mainly from disasters, higher insurance, and energy costs—with lower-income families and certain regions hit disproportionately, from @kclausing.bsky.social, Knittel, and @cwolfram.bsky.social www.nber.org/papers/w34525

Seven-day-ahead weather forecasts in high-income countries are more accurate than one-day-ahead weather forecasts in low-income countries.

Here's my thread of this year's new scholars in Economics of Education and Education Policy.

These PhD students and postdocs are on the job market, so take a look (and spread the word to others who might benefit from exposure).

And now onto the scholars... 👇

Wow. This is the paper I have been waiting for. Mobile apps are brain rot, with meaningfully bad economic consequences for those who overuse them.
