近期，上财经院经济学系的杨哲教授的著作论文“The Weak α-core of Exchange Economies with a Continuum of Players and Pseudo-utilities”在数理经济学一流期刊、我校经济学国际二类期刊Journal of Mathematical Economics上正式发表。
此外，他与我院博士生张弦的合作论文“Aweak α-core Existence Theorem of Games with Nonordered Preferencesand a Continuum of Agents”也已在该期刊上在线发表。
论文摘要
The Weak α-core of Exchange Economies with a Continuum of Players and Pseudo-utilities
Abstract: In this paper, we introduce the notion of the weak α-core for exchange economies with a continuum of players and pseudo-utilities, and establish the nonemptiness theorem of the weak α-core.
A weak α-core Existence Theorem of Games with Nonordered Preferencesand a Continuum of Agents
Abstract: Inspired by Kajii (1992) and Askoura (2011, 2017), we introduce the notion of the weak α-core for games with nonordered preferences and a continuum of agents. First, we extend the work of Kajii (1992) to games with spaces of strategies defined on Hausdorff topological vector spaces. Furthermore, we prove the nonemptiness of the weak α-core. Finally, we establish the relations between normal-form games, games with nonordered preferences and games with pseudo-utilities.
