Professional Investor Relations within the Firm
研究公司设立内部投资者关系部门对信息披露、分析师关注、机构投资者持股、流动性和市场估值的影响，并分析公平披露规则（Reg FD）冲击下这些公司的表现变化。
ABSTRACT: This paper investigates the effect of investments in internal investor relations (IR) departments on firm outcomes. We find that companies initiating internal professional IR experience increases in disclosure, analyst following, institutional investor ownership, liquidity, and market valuation relative to a matched sample of control firms. We also examine the differential impact the exogenous shock of Regulation Fair Disclosure (Reg FD) had on firms with an established professional IR department. We find these IR firms more than doubled their level of public disclosure post-Reg FD. Despite IR firms losing a potential communications channel following Reg FD adoption, we find they did not suffer adversely and instead show a post-Reg FD increase in analyst following, institutional investors, and liquidity relative to a control sample of similar non-IR firms. This implies that the effectiveness of professionalized internal IR increased post-Reg FD consistent with IR firms being relatively better positioned to navigate the more complicated regulatory environment.
