Present Bias: Lessons Learned and To Be Learned
回顾了现时偏向理论在过去20年的进展，包括理论理解和实证应用，并指出未来研究方向，适合对行为经济学和时间偏好感兴趣的学者。
While present bias is an old idea, it only took hold in economics following David Laibson's (1994) dissertation. Over the past 20 years, research has led to a much better theoretical understanding of present bias, when and how to apply it, and which ancillary assumptions are appropriate in different contexts. Empirical analyses have demonstrated how present bias can improve our understanding of behavior in various economic field contexts. Nonetheless, there is still much to learn. In this paper, we give our assessment of some lessons learned, and to be learned.
