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.
Only registered participants can attend this conference. Further information available on the congress website https://www.iseg.ulisboa.pt/en/event/iipf/ .

The Precious Networks of the Rich: How the Wealthiest Shape the Tax Agenda 1: Central European University, Vienna, Austria; 2: NYU Abu Dhabi, United Arab Emirates; 3: Tax Justice Network, United Kingdom; 4: University of Mannheim, Germany Despite broad public support for progressive taxation, the current U.S. tax system is among the most regressive in history. This paper tests whether social and institutional ties between legislators and the ultra-rich help explain this mismatch. We use large language models to classify the progressivity of the full universe of tax-related bills introduced in Congress since 1973. Using publicly available biographies, we then construct a new dataset linking Members of Congress to billionaires through overlap in higher-education institution, program, and graduation cohort. Our preliminary findings suggest that legislators with greater exposure to billionaires during college and university are more likely to sponsor regressive tax proposals and fewer progressive ones. These results support the view that elite networks can transmit political influence through informal social channels. The paper identifies a measurable pathway of elite influence and speaks to debates on transparency, accountability, and unequal political representation in the United States.
