Dear all,
The next presentation in the Online Social Choice and Welfare Seminar will be next Tuesday (10 June). Here are the details.
Time: 9AM GMT (5AM Toronto/Montréal, 6AM Rio de Janeiro, 10AM London, 11AM Paris, 12PM Istanbul, 2:30PM New Delhi, 6PM Tokyo/Seoul, 7PM Sydney, 9PM Auckland)
Speaker: Noriaki Kiguchi (Institute of Economic Research, Kyoto University)
Title: "Collective State Spaces"
Abstract: This paper aggregates individuals’ preferences over menus of lotteries into social preferences. Specifically, we consider the case where both individuals and society have preferences for flexibility (Dekel et al., 2001). That is, they face uncertainty regarding future states that determine their tastes over lotteries, leading them to prefer larger menus at the current time. Each individual’s future tastes are influenced by different aspects of future states, implying that each has their own state space. This paper axiomatically characterizes how society should construct a collective state space, which represents the entire set of factors influencing society’s future tastes. All of our axioms are motivated by discussions on the Pareto principle.
Reminder: On the seminar website you can find the video recordings, slides and supplementary materials for all past presentations, as well as information about future presentations.
