Bottom Line of Green Policies: Pollution Prevention and Firm Performance

Extensive research has investigated the linkage between environmental, social, and governance (ESG) practices and corporate financial outcomes; however, the specific implications of pollution prevention (PP) measures for firm performance remain comparatively understudied. Drawing upon theoretical insights from the resource-based view (RBV) and the natural resource-based view (NRBV), this study seeks to bridge this gap by providing an integrated examination of how PP practices influence firm performance over varying time horizons. This paper aims to empirically assess the short-term and long-term impacts of PP strategies on firm performance. Specifically, it investigates immediate financial metrics, such as profitability, solvency, and operational efficiency, as well as long-term outcomes measured by market valuation. In doing so, the study contributes to the understanding of whether initial compliance costs are ultimately offset by sustained competitive advantages derived from PP initiatives. Utilizing a comprehensive panel dataset covering publicly listed U.S. firms from 2011 to 2019, this study employs rigorous econometric methodologies, notably propensity score matching (PSM) and augmented inverse probability weighting (AIPW), to address potential selection bias. The analysis incorporates industry fixed effects alongside extensive controls for firm-specific characteristics, including management robustness, board composition and size, financial leverage, and capital structure. The empirical findings reveal a complex relationship between PP practices and firm performance. While firms initially experience adverse short-term effects, including declines in profitability, operational efficiency, and solvency due to compliance-related expenditures, these negative impacts are subsequently mitigated in the long run. Indeed, sustained commitments to PP practices correlate positively with enhanced market valuation. The results highlight the pivotal role of robust governance structures, diverse and adequately sized boards, prudent capital management, and strategic leverage decisions in successfully navigating the trade-offs associated with pollution prevention. Consequently, managers and policymakers are advised to carefully balance short-term financial constraints with long-term strategic investments to optimize the value derived from environmentally responsible practices.
