Abstract

•We study a raw database of all CVs posted in the Lattes platform, for all subject areas.•The scientific output between areas of science is heterogeneous in terms of quantity and expected impact.•We find that male researchers are more productive than female, but only when looking at the quantity of publications.•Researchers with PhD obtained abroad are more likely to publish in journals of higher impact.•The time duration of the PhD has a positive impact over the expected impact but negative for the quantity of publications.

We assemble a massive sample of 180,000 CVs of Brazilian academic researchers of all disciplines from the Lattes platform. From the CVs we gather information on key variables related to the researchers and their publications. We find males are more productive in terms of quantity of publications, but the effect of gender in terms of research impact is mixed for individual groups of subject areas. For all fields of science, holding a PhD from abroad increases the chance for a researcher to publish in journals of higher impact. We also find that the more years a researcher takes to finish his or her doctorate, the more likely he or she will publish less thereafter, although in outlets of higher impact. The data also support the existence of an inverted U-shaped function relating research age and productivity.
