EXPRESS: The Impact of Legal Protection of Trade Secrets on Advertising Spending: Insights from the Recognition of the Inevitable Disclosure Doctrine
研究了美国州法院认可不可避免披露原则（IDD）后，企业因商业秘密保护加强而增加广告支出，且该效应受CEO双重性、企业年龄和同行广告支出影响，最终提升销售额。
Protecting trade secrets is important for firms and policymakers because they are critical assets for firm performance and valuation. Extant research, however, seldom examines whether increases in trade secret protection have an impact on firms’ marketing actions to leverage their trade secrets, even though trade secret protection has limited value if firms cannot leverage them. Drawing on the attention-based view of the firm, this study proposes that stronger protection of trade secrets is likely to lead to higher managerial attention to leveraging trade secrets, resulting in higher advertising spending. The study tests this proposition by exploiting the staggered recognition of the inevitable disclosure doctrine (IDD) by U.S. state courts, a legal development that protects trade secrets by restricting employee movement to rival firms. The results show that firms headquartered in states that recognize IDD significantly increase their advertising spending. Consistent with the proposed contingency framework, the results also show that the positive effect of IDD recognition on advertising spending is weaker for firms with CEO duality but stronger for younger firms and firms in industries with higher peer advertising spending. Post hoc analyses show that increases in advertising spending following IDD recognition are associated with higher firm sales.
