Information Technology, Competition for Attention, and Corporate Efficiency

Discussant: Gabriela Stockler (NYU Abu Dhabi)
I study the effects of information technology (IT) progress in a model where stock prices aggregate speculators' information and guide firms' investments. A firm with higher exposure to risky production technology attracts more information from speculators. IT progress (i.e., lowering information costs) improves stock price informativeness and corporate efficiency when information is costly. Yet, when information is inexpensive, speculators use up their limited attention. Then IT improvements can backfire: Firms excessively increase risky technology exposure to engage in zero-sum competition for attention, reducing corporate efficiency and social welfare. Raising firms' growth opportunities can reinforce the adverse effects of IT progress.
Information Acquisition By Mutual Fund Investors: Evidence From Stock Trading Suspensions

This paper demonstrates that liquidity transformation provided by asset managers can boost firm-specific information production. We examine a setting where stocks become perfectly illiquid during trading suspensions: the prices and shares held by mutual funds “freeze.” Consistent with a model of liquidity-driven information acquisition, we find that investors analyze these illiquid holdings and reallocate capital in funds to take advantage of these stale prices. Once trading resumes, stocks exposed to liquidity transformation exhibit informative price movements about future firm fundamentals, reflecting the information produced by investors. Our findings suggest a liquidity channel through which asset management influences information production in capital markets.
