基于实验研究的恶性增资行为解释:自辨理论还是前景理论?

Interpretation of Escalation of Commitment Based on an Experiment Research: Self-justification Theory or Prospect Theory

恶性增资是一种常见的投资陷阱,学者们尚未就其产生原因给出普遍认可的理论解释。但一般认为,自辨理论、前景理论和委托代理理论是三种最主要的恶性增资解释理论。本文根据Staw提出的研究范式,通过角色扮演实验研究方法证明:在不存在委托代理关系的情况下,前景理论比自辨理论对决策者恶性增资行为具有更好的解释力。

Escalation of commitment is a well-know investment trap. There's no persuasive theory to interpret it. This paper, with an experiment research using the Staw's research paradigm, proved that Prospect Theory is more convincing than Self-justification Theory to interpret the escalation phenomenon where the principal-agent relationship absents.
