SUMMARY:

This doctoral thesis comprises three articles that use novel data on Brazilian twins to investigate key issues in labor economics.
The first article introduces TwinsBR, the largest twin dataset ever constructed, based on Brazilian administrative records.
The second article estimates the gender wage gap by comparing opposite-sex twins, controlling for unobservable factors such as family background and latent traits.
The third article examines the motherhood wage penalty by comparing same-sex female twins with and without children, finding a smaller effect than previously reported in the literature. By exploring the analytical potential of twin data in the Brazilian context, this thesis provides new empirical evidence on gender disparities. The findings highlight the importance of accounting for unobservable factors in economic analysis. The work also opens space for new methodological approaches in applied research.
