I co-authored "School Trajectories in Brazil (2008-2018)" with Estevão Vilela (preprint: osf.io/preprints/so...), derived from his Master's thesis. We find that student´s trajectories are not homogeneous, public policies cannot be generic; need to be tailored to student vulnerabilities.

great paper by Silvio C. Patricio www.pnas.org/doi/10.1073/... His study shows no evidence that the individual rate of aging has changed. Instead, it remains stable, suggesting that gains in life expectancy are more consistent with a later onset of senescence than with a slowing of its tempo.

Last week, we received Vegard Skirbekk, Norwegian Institute of Public Health and the University of Oslo, at UFMG. Vegard delivered two lectures focusing on population ageing and health. He also interacted with students in Demography and Public Health. Pictures: Lavinia Brandão - IEAT/UFMG

The article is here, and I'll have more to say in the coming days about how we came to this method of trying to answer, "How many Covid-19 deaths went uncounted in the US?"

Applying machine learning to identify unrecognized COVID-19 deaths recorded as other causes of death in the United States

A machine learning approach suggests that COVID-19 deaths were undercounted unevenly across sociodemographic groups in 2020–2021.

science.org

A great write-up on brand-new research I was involved in. We used a really different approach from the ones that we & many others have used previously to estimate how many Covid deaths there *really* were--almost 20% more than known. Our results broadly accord w others but add new demographic detail

The COVID-19 pandemic’s early death toll was much higher than the official U.S. count, according to a new study that spotlights dramatic disparities in the uncounted deaths. apnews.com/article/covi...

Forthcoming in the AER: "The Gender Pay Gap: Micro Sources and Macro Consequences" by Iacopo Morchio and Christian Moser.

The Gender Pay Gap: Micro Sources and Macro Consequences

(Forthcoming Article) - Using linked employer-employee data from Brazil, we document a significant gender pay gap, which is largely attributed to women working at lower-paying employers. To interpret this fact, we develop an equilibrium search model with endogenous firm pay, amenities, and hiring. We provide a constructive proof of identification of all model parameters. The estimated model suggests that amenities are important for both men and women, and that compensating differentials account for half of the gender pay gap. Equal-treatment policies partly close gender gaps but are not outputor welfare-improving.

Low birth rates have modest long run negative effects, after good effects for a few decades, and raising birthrates exacerbates dependency. A giant, apparently permanent, disconnect between expert opinion (e.g., below) versus manufactured panic hype on this issue pubs.aeaweb.org/doi/pdfplus/...
