在比下半连续更弱的假设下抽象经济的均衡(英文)

Equilibria of the abstract economies under an assumption weaker than lower semi-continuity

文章进一步研究了这样的抽象经济 ,它具有有限或无限维的非紧的策略空间 ,被约束对应限制下的偏好对应在弱下半连续或 2—下半连续的假设下 ,证明了抽象经济均衡的存在 .此外 。

economies with finitely or countable infinitely dimensional noncompact strategy spaces and prove the existence of equilibria with the assumption that preference correspondences confined by constraint correspondences are weak lower semicontinuous or 2-lower semicontinuous. Besides, we also improve the assumption on preference correspondences.
