NGO Activism and the Supply of Corporate Information

Jiamin Zhao Single-authored

Working paper Draft available on request

How does NGO targeting change what managers discuss with capital markets?

Abstract

This paper examines how NGO activism shapes managerial disclosure to capital markets. Using U.S. NGO targeting events and earnings-call transcripts, I find that environmental targeting is associated with greater climate-transition disclosure, while labor targeting is associated with less discussion of labor operating conditions. The findings suggest that NGO activism can selectively reshape investor-facing information supply, highlighting the role of shareholder-stakeholder interest alignment in external corporate governance.

Working paper

How Firms Govern Automated Data Access: Evidence from Robots.txt Policies

Jiamin Zhao, Long Cheng, and Igor Kadach

Working paper Draft available on request

How do firms govern automated access to information that remains publicly available?

Abstract

This paper constructs a novel historical measure of corporate digital information-access policies using archived web-access directives for U.S.-listed firms over the 2001-2024 period. We document substantial and persistent heterogeneity in how firms govern automated access to publicly available information, including whether restrictions apply broadly or selectively to named agents. We validate the measure using externally documented changes in web-access rules and characterize the long-run evolution of firms' machine-access policies. The evidence identifies automated access as a distinct dimension of corporate information policy: public availability does not imply unrestricted machine access, and firms actively govern both margins.
