To constrain the use of intangible assets in tax-motivated state income shifting, many U.S. state governments adopted addback statutes. Addback statutes reduce the tax benefits that firms can gain from creating intangible assets such as patents. Using a sample of U.S. public firms, we examine the effect of addback statutes on corporate innovation behavior. First, the adoption of addback statutes leads to a 4.77 percentage point decrease in the number of patents and a 5.12 percentage point decrease in the number of patent citations. Second, the “disappearing patents” resulting from addback statutes have significant economic value. Third, after a state adopts an addback statute, a firm with material subsidiaries in that state assigns fewer patents to subsidiaries in zero-tax states, whereas the number of patents assigned to the other states does not change. Overall, our findings suggest that addback statutes impede corporate innovation.

We build a novel comprehensive data set of new product trademarks as an output measure of product development innovation. We show that risk-taking incentives in CEO compensation motivate this type of innovation and that this innovation improves firm performance. Using an exogenous shock to executive compensation, we find that reductions in stock option compensation cause reductions in new product development. We also find that firms undertaking new product development experience increases in future cash flow from operations and return on assets. These findings suggest the importance of product development innovation to firms and new trademarks as a novel innovation measure.

This paper examines the influence of labor market power in the audit profession. Using a dataset of online job postings, we confirm that audit offices in more concentrated labor markets have greater labor market power and exercise it in the form of higher skill requirements and greater required effort from their auditors, at similar or slightly lower wages. We then show that client firms of audit offices in more concentrated labor markets are less likely to restate their earnings and have lower absolute discretionary accruals. These findings are only present when employees have lower mobility across professions and geographies, consistent with audit offices’ power in the local labor market explaining the results. Collectively, our findings highlight the importance of labor market power in understanding audit quality. Data Availability: Data are available from the sources cited in the text.
