为鼓励会计学科教师与研究生从其他学科汲取“养分”，我们拟组织“厦门大学会计学系‘群贤’交叉学科论坛”，借以鼓励学科交融、达到“他山之石”的目的。

“厦门大学会计学系‘群贤’交叉学科论坛” 的“群贤”一词，取“群贤毕至”之意。该论坛拟敦聘人文社科、理工及相关学科的学者作为主讲人，向会计学科师生介绍各自相关领域的最新进展，激发思想碰撞，促进相互交流。该论坛希望会计学科青年教师与研究生能够：(1)了解相关学科的最新进展，扩大知识面和视野；(2)借鉴相关学科的研究方法与研究视角；(3)寻求学科交融的可行性。

“厦门大学会计学系‘群贤’交叉学科论坛”的时间定于周二下午[不定期]，将与既有的“厦门大学会计学科教师与研究生系列Seminar”[每周二下午]与“财务、会计Seminar”相互补充，各有侧重。

题  目：Do You Hear the People’s Saying? Retail Investor Activism

报告人：杨  勇  教授

论文摘要：In a setting where market regulators provide supportive measures, we study whether and when retail investors turn more active in engaging with firm management and whether such engagement has economic consequences. We find that, consistent with retail investors’ general inclination to free-ride on sophisticated investors for corporate governance, they become more active in interacting with management when institutional investors, especially the active ones, withdraw from the firm: They are more proactive in requesting information from management. At the same time, they are more likely to lodge complaints about and offer suggestions and advice to management. Other than information about firm performance and stock prices, retail investors also enquire about various fundamental issues such as corporate governance, accounting treatments, business operation, material transactions, and macro-policy effects. In addition, retail investors also become more active after the firm experiences poor performance, namely, when the firm faces urgency for performance improvement and they are left behind by sophisticated investors due to their information disadvantage and the disposition effect. Finally, retail investors seem to possess information about a firm’s ongoing fraud and their active engagement with the firm helps shorten the duration of the fraud.

题  目：The Impact of the Tax Cuts and Jobs Act on the U.S. Defined Benefit Plans

论文摘要：The Tax Cuts and Jobs Act (TCJA) decreases the corporate tax rate from 35% to 21% while limiting the deductibility of business interest expense to 30% of EBITDA. We examine how these changes in tax law affects the U.S. defined benefit plans (hereafter, “DB plans”). Specifically, we test whether firms increase voluntary contributions to their defined benefit plans before the new tax rate become effective. We find that after the TCJA was passed, tax-paying firms significantly increase the voluntary contributions to their DB plans in the year preceding TCJA implementation. Moreover, firms with higher free cash flow, more future investment opportunities, higher funded status, and larger pension obligations for active participants are more incentivized to contribute to their DB plans. Furthermore, we investigate whether firms rebalance plan asset investments, as the funded status improves from the surge in voluntary contributions due to the TCJA. We show that firms are switching to the “liability-driven investment” strategy (“LDI strategy”) by investing plan assets in fixed income securities.
