(New) 5 February 2026, Computational Social Choice Seminar, Daniel Barreto
Speaker: Daniel BarretoTitle: Redistribution through Market SegmentationLocation: Room L2.06, Lab42, Science Park 900, AmsterdamAbstract
We study how to optimally segment monopolistic markets with a redistributive objective. We characterize optimal redistributive segmentations and show that they (i) induce the seller to price progressively, i.e., charge richer consumers higher prices than poorer ones, and (ii) may not maximize consumer surplus, instead granting extra profits to the monopolist. We further show that optimal redistributive segmentations are implementable via price-based regulation.

Speaker: Rachel RuelléTitle: A Ceteris Paribus Borda Solution to the Social Ranking ProblemLocation: Room L2.06, Lab42, Science Park 900, AmsterdamIn our society, individuals are often rewarded based on their merits when they work in cooperation. In this presentation, we focus on a novel social ranking solution where individuals are ranked based on the pairwise comparison of coalitions that differ for one single element (denoted in the related literature as Ceteris Paribus (CP-)comparison).

3 - 14 August 2026, 37th European Summer School in Logic, Language and Information (ESSLLI 2026), Prague (Czech Republic)
Location: Prague (Czech Republic)Deadline: Wednesday 1 October 2025Under the auspices of the Association for Logic, Language, and Information (FoLLI), the European Summer School in Logic, Language, and Information (ESSLLI) runs every year. Except for 2021, when the school was virtual, it runs in a different European country each year. It takes place over two weeks in the summer, hosts approximately 50 different courses at levels that run from foundational to introductory to advanced, and attracts around 400 participants from all over the world. In 2026, ESSLLI returns to Prague after exactly 30 years.
The main focus of ESSLLI is the interface between linguistics, logic and computation, with special emphasis on human linguistic and cognitive ability. Courses, both introductory and advanced, cover a wide variety of topics within the combined areas of interest: Logic and Computation, Computation and Language, and Language and Logic. Workshops are also organized, providing opportunities for in-depth discussion of issues at the forefront of research, as well as a series of invited evening lectures.
