谁说女子不如儿郎?——P2P投资行为与过度自信
原刊和作者:
《金融研究》2017年第11期
摘要
本文用“人人贷”网站五千多名投资者的交易数据,提供了互联网金融市场上男性过度自信的新证据。以往文献多分析股票市场中的性别效应,但由于股票交易的复杂性研究结论易受风险偏好、信息不对对称、预算约束等假说的挑战。我们利用用P2P线上交易数据,可以降低这些干扰因子的影响。在“人人贷”投资者中,男性换手率比女性高167基点,年化投资收益率低24基点。这些区别在高换手率、低收益率的子样本中更为显著。使用倾向性得分匹配控制风险偏好、个体特征差异,使用Heckman两阶段模型控制样本自选择问题,并选取无约束子样本排除预算约束等竞争性假设后,结果依然显著。进一步研究发现,这些性别差异的主要原因是男性过度交易从而付出更多交易费用。当不考虑交易成本时,男女投资者的收益率没有显著差别。
Trust Busting: The Effect of Fraud on Investor Behavior

Abstract
We study the importance of trust in the investment advisory industry by exploiting the geographic dispersion of victims of the Madoff Ponzi scheme. Residents of communities that were exposed to the fraud subsequently withdrew assets from investment advisers and increased deposits at banks. Additionally, exposed advisers were more likely to close. Advisers who provided services that can build trust, such as financial planning advice, experienced fewer withdrawals. Our evidence suggests that the trust shock was transmitted through social networks. Taken together, our results show that trust plays a critical role in the financial intermediation industry.
