Some information on the session logistics:
If not stated otherwise, the discussant is the following speaker, with the first speaker being the discussant of the last paper. The last speaker of each session is the session chair. (Exception: invited sessions)
Presenters should speak for no more than 20 minutes, and discussants should limit their remarks to no more than 5 minutes. The remaining time should be reserved for audience questions and the presenter’s responses. We suggest following these guidelines also in the (less common) 3-paper sessions in a 2-hour slot, to allow participants to move between sessions. Discussants are encouraged to avoid summarizing the paper. By focusing on a few questions and comments, the discussants can help start a broader discussion with the audience.

Insights From Recent Trends In Social Security Contributions In Portugal ISEG, Portugal This paper examines Social Security contribution dynamics in Portugal during 2019–2024 using granular administrative records. It assesses contributors, earnings, and effective rates to disentangle drivers of revenue across demographic groups and sectors, emphasizing fiscal implications. The main finding is that revenue growth was propelled chiefly by rising earnings, with additional support from higher employment, lifting the contribution‑to‑GDP ratio. Ageing continues to dampen medium‑term prospects, but recent immigration temporarily offsets this by expanding contributors in prime ages; however, lower average earnings among foreign workers limit near‑term fiscal payoffs despite their stronger attachment to the general regime. Gender gaps are modest overall yet fiscally relevant: faster female earnings growth boosts revenue and indicates potential medium‑term gains from continued convergence. Sectorally, contributions are increasingly concentrated in services, particularly high‑skill activities, while compositional shifts within industry reduce average yields. Overall, administrative contribution data are crucial for gauging revenue sustainability and guiding public finance policy.
