This paper empirically analyzes pollution abatement regulation within the context of the Clean Air Act's nonattainment status designation and shows that financial constraints are an important determinant of whether spending on mandatory pollution abatement crowds out or stimulates R&D investment and capital expenditure. We show that spending on mandatory pollution abatement and other investments are complements for financially unconstrained firms but substitutes for constrained firms. Financially unconstrained firms invest more and have lower current profits but higher future profits; financially constrained firms invest less and have stable current profits but lower long-term profits.

Many policymakers and practitioners argue that corporations may become more stakeholder focused if employees are given more power. We study the causal impact of unionization on stakeholders by analyzing how close labor union elections affect environmental and social (E&S) scores. We find that unionization is associated with an increase in internal social scores that primarily benefit employees and a decrease in external E&S scores that primarily benefit non-employees. The negative effects on external E&S are amplified when firms have greater financial constraints. The effects on both internal and external E&S are magnified when labor unions have more bargaining power. Our results suggest that policymakers consider implications for all stakeholders before implementing policies that prioritize the corporate influence of one stakeholder group.

Analyzing 48 foreign exchange (FX) rates and 1.2 million FX-related news articles over a 35-year period, using digital textual analysis, we find that a currency reversal investment strategy that buys (sells) currencies with low (high) media sentiment offers strong positive and statistically significant returns and Sharpe ratios. The results are robust and the strategy adds value over other currency premia determinants. Analysts’ forecasts systematically mispredict the reversal strategy. This is the first article to show that price reversals based on media sentiment are a well-defined feature of the FX market.

We use staggered share repurchases legalization from 1985 to 2010 across the world to examine its impact on corporate behaviors. We find that share-repurchasing firms do not cut dividends as a substitution. The cash for repurchasing shares comes more from internal cash than external debt issuance, leading to reductions in capital expenditures and R&D expenses. While this strategy boosts stock prices, it results in lower long-run Tobin's Q, profitability, growth, and innovation, accompanied by lower insider ownership. Tax benefits and paying out temporary earnings are two primary reasons that firms repurchase.

We find that the effect of political connections on tax planning depends on firms’ financial conditions. After increased political connections, financially unconstrained firms increase tax planning and spending on tax services, as documented in prior studies, whereas constrained firms decrease tax planning and spending on tax services. Moreover, decreases in tax planning are only present for constrained firms that obtain new bank loans and public debt and when the connected politicians serve on banking-related committees. Our results suggest that by facilitating access to external financing, political connections reduce financially constrained firms’ use of tax planning as an internal financing tool.
