Abstract

Corporate political activity (CPA), lobbying and political contributions intended to influence the policy environment may either complement or crowd out real investment. This study examines when CPA is investment-enhancing by combining firm- and year-fixed effects, Dynamic System-GMM for mean-level endogeneity, and fixed-effects quantile and IV-quantile regressions to recover distribution-varying effects with endogenous CPA. Using firm-year data for Fortune World’s Most Admired Companies (2016–2022), results show that CPA is associated with higher investment at lower quantiles, consistent with uncertainty-buffering and financing-access channels, but attenuates and can turn negative at upper quantiles, consistent with diversion at high CPA intensity; the overall pattern is inverted-V. Two firm-level boundary conditions are introduced: Corporate Governance and Ethical Leadership. Both moderators amplify the positive CPA–Investment association in the lower tail and temper adverse upper-tail effects. Findings are robust to alternative investment proxies (CAPEX/Assets, asset growth, R&D intensity), CPA scaling, timing placebos, balanced subsamples, and instrument choices.
