Pignataro (Reference Pignataro2025) contains an error in the final paragraph of the Case Selection section.

In Costa Rica, TSE resolution 4757-E8-2021 does not require that at least one vice-presidential candidate be female. Instead, the resolution clarifies that parties must nominate at least one woman and at least one man among the three positions on the presidential ticket. This allows the nomination of two male vice-presidential candidates if the presidential candidate is a woman, and two female vice-presidential candidates if the presidential candidate is a man.

The mistake does not affect the statistical results, as the 2022 Costa Rican election –held after the resolution was enacted– was excluded from the regression models.
