讲座内容：
为了研究信息冲击对一系列公司决策的影响，我们使用期权可用性的外生变化作为工具。经过研究结果显示，期权引入对涉及资产负债表双方的公司政策具有因果影响。在更大程度上创新和提高信息的质量和效果。它还减少了使用支出和债务来应对机构和信息摩擦的需要。我们进一步进行了两个独立的实验，表明我们的仪器的影响不是通过其他渠道。总体来说，期权有效性对企业具有正向的信息溢出效应，在企业决策方面，期权可得性并不是一种附带的表现。
To examine the impact of shocks to information on an array of corporate decisions we use exogenous variations in options availability as an instrument. Our results indicate that option introductions have causal impact on corporate policies concerning both sides of the balance sheet. The improved information quality results in greater investment and more and better innovation. It also reduces the need to use payout and debt in response to agency and information frictions. We further conduct two independent experiments showing that the impact of our instrument is not through alternative channels. Overall, options availability has a positive information spillover effect on firms and they are not a side show when it comes to corporate decisions.
