My dissertation consists of three chapters that examine how information production by financial intermediaries impacts on the capital market.My first chapter investigates whether extreme but rare events, i.e., major climatic disasters, influence the productivity of professional financial analysts, whose output is highly crucial in the capital market. We use 21 major natural disasters in the U.S. and find that disaster-zone analysts reduce their forecast accuracy by reiterating their previous forecast within 3 months after disasters. This effect is driven by distracted attention, rather than resource constraints. Though the effect is short term, we reveal a spillover negative impact from climatic disasters to information environment of firms which do not experience disasters, via the channel of disaster-zone analysts, highlighting the importance of the financial intermediary and also the economic consequences of severe climate events. My second chapter is motivated by the increasing global expansion by U.S. firms in recent decades and examines how geographic distribution of U.S. firms’ offshore network affects the coverage incentive of non-U.S. analysts. We combine analyst country location database and the novel dataset of offshore activities by Hoberg and Moon (2017) who quantify a U.S. firm’s local exposure in a foreign country and we discover that foreign analysts, are more likely to initiate coverage of U.S. firms with offshore activities in their domiciled countries and provide more accurate forecasts compared to non-domiciled foreign analysts. This study uncovers an important channel, i.e., offshore network, through which non-U.S. analysts can contributes to U.S. market with information advantage. In my third chapter, I study an emerging group of equity analysts, i.e., social media analysts, who post equity research on social media platforms and share investment opinions. I employ initial public offering (IPO) as a laboratory setting because during pre-IPO period, a period with high information asymmetry, professional sell-side analysts are restricted to issue reports under the restriction enforced by SEC, which provides a great setting to study the informational role of this group. I exploit research articles on Seeking Alpha website and find that pre-IPO social media analyst coverage has a positive impact on first day initial return, with the effect driven by heightened retail investor attention. This study highlights the role of social media analysts, as a new information intermediary in the capital market during the internet era. / Business Administration/Finance
