In contrast with traditional possibility correspondence, this model addresses both technical and cognitive limitations that lead to empty information sets. These sets, interpreted as the absence of sensory signals, prevent agents from recalling or updating knowledge. Market behavior during the subprime mortgage crisis and asymptomatic COVID-19 infection illustrates the model. We also redefine the knowledge operator within this framework and explore its implications for non-trivial unawareness. The model demonstrates that, even when agents receive no signals, they default to habitual behavior rather than conscious decision-making. 中央大学経済研究所 2024-10-09 eng departmental bulletin paper VoR https://doi.org/10.24789/0002001883 https://chuo-u.repo.nii.ac.jp/records/2001883 10.24789/0002001883 経済研究所 Discussion Paper IERCU Discussion Paper 406 1 34 https://chuo-u.repo.nii.ac.jp/record/2001883/files/dp406.pdf 343.7 KB
