摘要
来自ipo的证据表明,创业企业的初始估值往往被高估(Fisher, 2014)。一种常见的解释是企业家的非理性特征是过度自信(Galasso和Simcoe, 2011)。我们提供了一种不同的、理性的解释,我们称之为估值师的诅咒。它在本质上类似于拍卖中的赢家诅咒(Thaler, 1988)和决策分析中的优化者诅咒(Smith and Winkler, 2006),但诅咒的来源既不是来自拍卖类型机制的竞争效应,也不是来自备选方案选择中的优化效应。相反,效果是在评估本身产生的,即使评估的输入是无偏的。我们提供了导致估价师诅咒的一般条件,表明它们即使在贝叶斯设置中也会持续存在,并提出了几种减轻影响的方法。
The Valuator's Curse or the Entrepreneur's Boon: Decision Analysis of Post-IPO-Launch Disappointment
Evidence from IPOs show that the initial valuations of entrepreneurial ventures tend to be overvalued (Fisher, 2014). One common explanation is irrationality on the part of the entrepreneur characterized by overconfidence (Galasso and Simcoe, 2011). We provide a different, rational explanation which we term the valuator's curse. It is similar in nature to the winner's curse in auctions (Thaler, 1988) and the optimizer's curse in decision analysis (Smith and Winkler, 2006), but the source of the curse is neither from the competitive effects of an auction-type mechanism nor from the optimization effects in a choice among alternatives. Rather the effect is generated in the evaluation itself, even though the inputs to the evaluation are unbiased. We provide general conditions which result in the valuator's curse, show that they persist even in a Bayesian setting, and suggest several approaches to mitigate the effect.
