This paper examines the sharp decline in fertility across Latin America using both period and cohort measures. Combining Vital Statistics, Census microdata, and UN population data, we decompose changes in fertility by age, education, and joint age–education groups. We show that the decline in period fertility between 2000 and 2022 is driven primarily by reductions in within-group birth rates rather than by changes in population composition, with the largest contributions coming from younger and less-educated women. Comparing the cohort born in the mid 1950s and the one born in the mid 1970s, we find that the decline in completed fertility reflects not only delayed childbearing but also substantial reductions in the average number of children per woman. This is driven primarily by lower fertility among mothers rather than by rising childlessness. Our findings provide new evidence on the nature of Latin America’s transition to below-replacement fertility and highlight several open questions for future research.

This study explores the psychological profiles of elite soccer players, revealing that success on the field goes beyond physical ability. By analyzing a sample of 328 participants, including 204 elite soccer players from the top teams in Brazil and Sweden, we found that elite players have exceptional cognitive abilities, including improved planning, memory, and decision-making skills. They also possess personality traits like high conscientiousness and openness to experience, along with reduced neuroticism. Using AI, we identified unique psychological patterns that could help in talent identification and development. These insights can be used to better understand the mental attributes that contribute to success in soccer and other high-performance fields.

By Bryan Caplan, now on sale. From Bryan’s Substack:
My latest book of essays, You Have No Right to Your Culture: Essays on the Human Condition, flips this narrative. All of these demands for “reshaping culture” are thinly-veiled calls for coercing humans. As the title essay explains:
[C]ulture is… other people! Culture is who other people want to date and marry. Culture is how other people raise their kids. Culture is the movies other people want to see. Culture is the hobbies other people value. Culture is the sports other people play. Culture is the food other people cook and eat. Culture is the religion other people choose to practice. To have a “right to your culture” is to have a right to rule all of these choices — and more.
What’s the alternative? Instead of treating capitalism as the root of cultural decay, the world should embrace capitalist cultural competition. Actions speak louder than words; instead of using government to “shape” culture, let’s see what practices, beliefs, styles, and flavors pass the market test. Which in practice, as I explain elsewhere in the book, largely means the global triumph of Western culture, infused with an array of glorious culinary, musical, and literary imports. Nativists who bemoan immigrants’ failure to assimilate are truly blind; the truth is that even non-immigrants are pre-assimilating at a staggering pace.
Recommended. Bryan also offers some essays on what he finds valuable in GMU Econ sub-culture.

Shikha Dalmia moderates, here is the link. Excerpt from the summary:
One reason for the populist revolt in America is the notion of the “deep state”—that an unaccountable bureaucracy is secretly ruling the country. Frank and Tyler come from very different intellectual traditions. Frank, a centrist, is a student of Max Weber and Tyler is a limited government libertarian. Yet they have both argued that liberal states in complex modern societies need a functional bureaucracy—a.k.a. state capacity—to deliver public goods and solve collective action problems. But they also have a ton of disagreements, especially on just how broken American governance is—and they duke it out in a spirited discussion.
And an excerpt from me:
Cowen: I don’t think American state capacity historically is that weak. We built this incredible empire, often unjustly. We put a man on the moon. We developed the atom bomb. We’re leaders in aviation and computers in part because of government. A lot of our state governments work really quite well. It’s a mixed bag, but I think we’d be in the world’s top 10 easily. Noah Smith had a great blog post on this.
Self-recommending! And yes with tons of disagreement, the dialogue is a good overview of where my views are at in this moment, stated super clearly as usual. There is a transcript at the link, it is easy to read through the slight typos.
