The Costs of Silence: The Impact of Misinformation Regulation on Finfluencers and Corporate Information Environment

Last update: March 04, 2025

ABSTRACT: Using the unique context of social media censorship in China, we investigate how misinformation regulation on investor-focused social media platforms influences the behavior of platform influencers (i.e., finfluencers) and its subsequent effects on capital markets. Our findings reveal that misinformation regulation significantly increases account deletions among finfluencers, particularly those exhibiting a more negative tone prior to the regulation. Additionally, remaining finfluencers respond strategically by posting fewer messages and adopting a more positive tone in their content. Despite these behavioral adjustments, the regulation proves ineffective in enhancing the corporate information environment. This is evidenced by a decline in price informativeness, as reflected in weaker correlations between current stock prices and future earnings news, alongside heightened short-term market reactions to earnings announcements. Furthermore, we provide indirect evidence of potential regulatory capture amidst misinformation regulation. Overall, our results underscore the need for caution when implementing regulatory interventions on investor-focused social media platforms.

Communication Technology and Student Loan Borrowing Behavior: Evidence from the Rollout of Facebook

Last update: July 19, 2025

ABSTRACT: Using quasi-experimental variations in college students’ exposure to Facebook, I document the unintended consequences of communication technology on student loan borrowing behavior. My estimates show that the rollout of Facebook at a college reduces the number of student loan recipients by 7.965%, equivalent to approximately 215 fewer recipients based on the sample mean. I also find consistent declines in both the number and dollar amount of disbursements. Utilizing the variations in state minimum wage and college location, I provide evidence that these effects are driven by improved part-time job search efficiency. Further analysis suggests the reallocation of student loans in the context of Facebook, associated with racial minority status, ex-ante human capital investment, and the rent-seeking behavior of private for-profit institutions. Taken together, the findings indicate that communication technology can reduce students’ reliance on student loans by enhancing labor market engagement. This study offers insights into the demand-side determinants of student loan borrowing and reveals how the diffusion of digital platforms influences the allocation of debt resources, informing policy considerations.
