Clumped or Piecewise? Evidence on Preferences for Information
通过实验室彩票实验，检验人们是否偏好集中获取信息而非分散获取，发现总体上并不厌恶分散信息，并验证了结果的稳健性。
In this paper we examine individuals' attitudes toward the timing of information. We test a theoretical prediction that people prefer to get information “clumped together” rather than piecewise. We conduct a controlled lab experiment where subjects participate in a lottery and can choose between different resolutions of uncertainty (clumped or piecewise) and analyze which kind of resolution is preferred. Two additional treatments allow us to get a quantitative measure of subjects' preferences over different information structures. Our data provide little support for a systematic aversion to piecewise information on the aggregate level. In additional treatment conditions, we demonstrate the robustness of our findings and explore potential explanations.
