정보와 신념, 그리고 경제적 합리성

Abstract

To behave rationally, one must have rational preferences as well as rational beliefs. Economics, which is specialized in the study of rational choice, explicitly discusses the problem of rational preferences. Hoswever, instead of directly dealing with the problem of rational beliefs, it assumes that people have perfect information with respect to choices people face. There are heated controversies between economists and non-economists with respect to information and beliefformation. The purpose of this paper is to propose joint-research agenda between economist and non-economists by checking those controversies.
