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.

My conclusion is that much of the worry about sub-replacement fertility is overstated. Quantitatively, the net effect of even a large fertility reduction on the US economy would be a relatively small decline in the standard of living. Comparing demographic steady states and focusing on the most easily quantified channels, a version of the United States with a total fertility rate of one child per woman would have consumption per capita that was 8.7 percent lower than a version of the country where the TFR was two. In the first four decades of the transition following a decline in fertility below the replacement rate, consumption is actually higher than it would have been if fertility had remained constant. Indeed, much of the sturm und drang regarding the economic effects of current population aging is related to the ending of such a transitory period of good times that resulted from fertility declining from its Baby-Boom highs to near replacement, starting in the 1960s. Finally, it is important to note that any attempt to fix the economic problems stemming from low fertility by raising the birth rate will entail a period of higher overall dependency in the decades that it takes the resulting children to become productive adults.

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/...

fixest is an R package for fast and flexible econometric estimation, providing a comprehensive toolkit for applied researchers. The package particularly excels at fixed-effects estimation, supported by a novel fixed-point acceleration algorithm implemented in C++. This algorithm achieves rapid convergence across a broad class of data contexts and further enables estimation of complex models, including those with varying slopes, in a highly efficient manner. Beyond computational speed, fixest provides a unified syntax for a wide variety of models: ordinary least squares, instrumental variables, generalized linear models, maximum likelihood, and difference-in-differences estimators. An expressive formula interface enables multiple estimations, stepwise regressions, and variable interpolation in a single call, while users can make on-the-fly inference adjustments using a variety of built-in robust standard errors. Finally, fixest provides methods for publication-ready regression tables and coefficient plots. Benchmarks against leading alternatives in R, Python, and Julia demonstrate best-in-class performance, and the paper includes many worked examples illustrating the core functionality.

This suggests that synthetic populations based on the 2010 Census should be created using the contingency tables. Our evaluation shows that the so created synthetic population maintains the values and proportions of the contingency tables and presents totals close to those of the microdata.

The data composition strategies of the contingency tables and the microdata are different and, when comparing samples of both data, we find that the race variable in the microdata ignores the presence of minorities in some municipalities.

SeconFirstly, contingency tables are available at the municipal level, for strata defined by race, gender, and education and microdata with personal information. To preserve individual anonymity, the census collapsed some variables into broader categories and removed personally identifiable data.

The 2010 Brazilian Census contains a wealth of information that could enable research and inform policies in health, education, the economy, and other sectors. The census provides publicly available information in two forms.

In the dissertation, I analyzed the evolution and determinants of Brazilian worker retirement (1960–2000) using Censuses and Household surveys. Public pension systems are crucial for elderly well-being, making reform of the Brazilian public pension system essential.

Time to birth for spontaneous and ART births among infertile groups - PubMed While assisted reproductive technologies enable individuals facing infertility issues to achieve a live birth, they require more time to succeed. However, since the 2000s, time to ART births has decreased, with the shortest observed among those initiating conception attempts in their late thirties. …

💡 Time to ART birth decreased since the 2000s, and is shorter for those in their late 30s — likely reflecting improved treatment efficiency and faster access to care.
