The Costs of Silence: How the Enforcement of Misinformation Regulation Shapes Finfluencers and the Corporate Information Environment

Last update: April 26, 2026

ABSTRACT: Social media has reshaped the corporate information environment, but its net effect remains unsettled because of concerns about misinformation. We exploit a 2023 Chinese regulatory crackdown on misinformation by social media finfluencers to examine how enforcement of misinformation regulations affects finfluencers and the corporate information environment. Consistent with Chinese officials facing asymmetric payoff functions that penalize poor outcomes more heavily than they reward favorable outcomes, we find that enforcement increased deletion of finfluencer accounts, particularly among accounts with more negative tones. We further document a chilling effect: following the crackdown, finfluencers whose accounts were not deleted posted fewer negative and positive messages. Finally, we find that enforcement reduced stock price informativeness and stock liquidity. Overall, the evidence suggests that, despite its stated objective, enforcement of misinformation regulations worsened rather than improved the corporate information environment because of officials’ distorted incentives and finfluencers’ strategic responses.

Financial Disclosure by Government Contractors and Government Investment: Evidence from U.S. Research Universities

Last update: September 08, 2026

ABSTRACT: Using the implementation of Governmental Accounting Standards Board Statements No. 34 and 35 (GASB 34/35) across U.S. public colleges and universities, I examine how financial disclosure by research universities affects the allocation of federal research funding. I find that GASB 34/35 reduces federal research funding to public universities relative to private ones. The cross-sectional analyses suggest that enhanced monitoring and government learning are mechanisms through which GASB 34/35 affects funding decisions. Specifically, the decline is more pronounced among institutions with greater pre-reform administrative and academic complexity, and federal funding to public universities becomes more responsive to prior private gifts and state funding. My results further show that, after GASB 34/35, public universities experience a decline in publications relative to private universities, while both patent and publication output per unit of research expenditure increase. Additionally, I document a decline in faculty compensation across academic ranks at public universities. Overall, these results show that GASB affects government investment in the higher education sector.
