Exploiting staggered changes in state-level corporate income taxes, we document that corporate social responsibility (CSR) performance improves substantially following tax cuts, reflecting firms' reliance on internal funds for CSR investments. However, tax increases do not significantly weaken CSR performance, implying that CSR commitments are sticky on the upside. Tax cuts enhance CSR performance more for firms with greater tax exposure, tighter financial constraints, better corporate governance, stronger prosocial preferences, or higher risk. Additional analysis of the 2017 federal tax reform substantiates the CSR effect of tax cuts. Overall, our findings highlight essential CSR features and illustrate how corporate tax policy drives corporate sustainability.

We provide empirical evidence on the positive effect of non-executive employee stock options on corporate innovation. The positive effect is more pronounced when employees are more important for innovation, when free-riding among employees is weaker, when options are granted broadly to most employees, when the average expiration period of options is longer, and when employee stock ownership is lower. Further analysis reveals that employee stock options foster innovation mainly through the risk-taking incentive, rather than the performance-based incentive created by stock options.

We show that credit default swap (CDS) trading on a firm's debt positively influences its technological innovation output measured by patents and patent citations. This positive effect is more pronounced in firms relying more on debt financing or being more subject to continuous monitoring by lenders prior to CDS trade initiation. Moreover, after CDS trade initiation, firms pursue more risky and original innovations and generate patents with higher economic value. Further analysis suggests that CDSs improve borrowing firms’ innovation output by enhancing lenders’ risk tolerance and borrowers’ risk- taking in the innovation process, rather than by increasing Research and Development (R&D) investment. Taken together, our findings reveal the real effects of CDSs on companies’ investments and technological progress.
