研究室紹介
Professor Biung-Ghi Ju's research lab specializes in normative economics and social choice theory, focusing on fair allocation mechanisms in resource distribution problems. The lab investigates group identification, rights-based allocation rules, and the interplay between procedural justice and end-state fairness in contexts such as environmental resource sharing, water rights, and greenhouse gas emissions. Central themes include axiomatic characterization of fair allocation rules, particularly through egalitarian rights assignment and market-based mechanisms, and the theoretical foundations of justice in joint ventures and collective decision-making.

15Group identification refers to the problem of classifying individuals into groups (e.g., racial or ethnic classification). We consider a multinary group identification model where memberships to three or more groups are simultaneously determined based on individual opinions on who belong to what groups. Our main axiom requires that membership to each group, say the group of J's, should depend only on the opinions on who is a J and who is not (that is, independently of the opinions on who is a K
Abstract We model problems of allocating disputed properties as generalized exchange economies. Therein, agents have preferences and claims over multiple goods, and the social endowment of each good may not be sufficient to satisfy all individual claims. We focus on market‐based allocation rules that impose a two‐step procedure: assignment of rights based on claims first and voluntary exchange based on the assigned rights afterward. We characterize three focal egalitarian rights‐assignment rules
