Investor uncertainty about firm value drives investors’ information collection and trading activities, as well as managers’ disclosure choices. This study examines an important source of uncertainty that likely cannot be influenced by most managers and investors: uncertainty about government economic policy. We find that this uncertainty is associated with increased bid-ask spreads and decreased stock price reactions to earnings surprises. Managers respond to this uncertainty by increasing their voluntary disclosures, but these disclosures only partly mitigate the bid-ask spread increase. We conclude that government economic policy uncertainty is an important component of firms’ information environments and managers’ voluntary disclosure decisions.

We document an increase in market power for politically active firms during times of heightened policy uncertainty, when their information and influence advantage is greater. The effect is long-lasting and stronger for large politically active firms. We show that relatively large investments during high uncertainty periods serve as a potential mechanism for gains in market power. Industries populated with politically active firms experience lower business dynamism and import penetration, consistent with active firms leveraging investment timing to restrict competition. Results suggest that political activism is a likely contributing factor to the dominance of large firms over the last two decades.

ABSTRACT In this study, we examine whether sell-side security analysts gain access to value-relevant information through political connections. We measure analysts' political connections based on political contributions at the brokerage-house level. We argue that if brokerages are able to obtain private information through their political connections, then analysts at politically connected brokerages should issue more profitable stock recommendations, and this increased profitability should be more pronounced for politically sensitive stocks. Our evidence is consistent with these predictions. Analyses of recommendations issued surrounding the Affordable Care Act further support our main inferences. Moreover, our findings hold after we employ numerous tests to address correlated omitted variables and endogeneity. Collectively, these results suggest that brokerages obtain value-relevant, nonpublic information from their political connections. JEL Classifications: G24; G38; G14.

ABSTRACT Prior research suggests that (1) politically active firms have an information advantage over firms that do not engage in the political process but also that (2) politically active firms are more likely to disclose policy-related information. We examine whether there are externalities associated with the processing of political information by politically active firms. We study this question in the setting of intraindustry information transfers around earnings announcements. Measuring firms’ political activism using campaign contributions, we find stronger intraindustry information transfers from politically active firms to their industry peers. These information transfers are stronger when there is more discussion during conference calls of political topics that have industry- or market-wide implications. Similarly, these information transfers are also stronger when there is greater political uncertainty. Our paper highlights an important information externality related to politically active firms’ disclosures and improves our understanding of how politically active firms affect their industries’ information environment.
