We study how a regulator can best target inspections. Our case study is a US Occupational Safety and Health Administration (OSHA) program that randomly allocated some inspections. On average, each inspection led to 2.4 (9 percent) fewer serious injuries over the next 5 years. Using new machine learning methods, we find that OSHA could have averted as much as twice as many injuries by targeting inspections to workplaces with the highest expected averted injuries and nearly as many by targeting the highest expected level of injuries. Either approach would have generated up to $850 million in social value over the decade we examine. (JEL C63, J28, J81, K32, L51)

Why are some firms more successful in adopting profitable environmental management practices than others? A key role of corporate managers is to encourage subsidiaries to adopt innovative practices. We examine the conditions under which corporate managers use information provision to encourage subsidiaries to adopt advanced environmental management practices. Focusing on the distribution of expertise across subsidiaries, we propose that corporate managers are more likely to elect an information provision strategy when subsidiaries (i) possess moderate levels of related expertise, (ii) exhibit significant heterogeneity in this expertise, and (iii) are more diversified and less concentrated. We study the diffusion of pollution prevention practices by firms in the information and communication technology sector in the United States and find empirical support for our four hypotheses. These findings promote a greater understanding of which firms adopt advanced environmental management practices and when firms adopt information provision strategies to encourage knowledge transfer within the organization.

... To change the likelihood of a reaction, an intervention could entail removing environmental obstacles, changing a workstation, or introducing antecedents or consequences (Jones et al. 2024). Both during and after the intervention, the frequency, length, or rate of the target behaviour is recorded, and its results are compared to baseline assessments of behaviour (Viswanathan et al., 2024). ...

... It is worth highlighting that recent research has increasingly focused on the influence of climate change on business performance and sustainability [4][5][6][7][8][9][10][11][12][13]. Notably, a significant body of work has been dedicated to assessing the effectiveness of decarbonization in the oil and gas industry [6,[14][15][16][17][18][19][20][21][22][23][24][25]. ...

... These issues have mostly been studied from an ex-post impact evaluation perspective. More closely related to our paper, a recent study by Johnson et al. (2023) applied ML methods to micro-level establishment data on workplace injuries to evaluate alternative targeting strategies to random inspection allocation. They find that machine predictions could have prevented as many as twice as many injuries by targeting inspections to workplaces with the highest expected averted injuries. ...

... In recent years, sustainability has become a critical driver of corporate strategy, compelling firms to integrate environmentally responsible practices into their operations [1,2]. Heightened regulatory pressures, growing consumer awareness, and the rising costs of environmental degradation have created an urgent need for manufacturing firms to adopt green practices [3,4]. In response, companies are increasingly prioritizing a Green Competitive Advantage (GCA) and Green Innovation (GI) as essential components of long-term competitiveness in an environmentally conscious market. ...

... Of the two studies using more rigourous observational research methods, Lafuente and Abad [8] found that OHSAS 18001 adoption was associated with significant reductions in the work injury rate and that the cumulative OHSAS 18001 experience (additional years of certification) was also associated with significant reductions in the work injury rate. Meanwhile, Viswanathan et al. [11] using a propensity score-matched difference-in-differences (DiD) model, found that firms with OHSAS 18001 certification experienced 20% fewer injury and illness cases than the matched control group over the follow-up period. ...

... Researchers suggest that auditing systems are inherently ineffective due to the voluntary nature of implementation and compliance [26,32,33]. Likewise, researchers note the limitations of auditing practices for identifying labor rights violations in factories [34,35]. Further evidence supports this position by pointing out that both Tazreen Fashion in Bangladesh and Ali Enterpris in Pakistan passed audits shortly before disastrous factory fires kills hundreds of workers [31,36,37]. ...

This demand enhances the quality of climate governance and streamlines investment decisions, ultimately reducing adverse selection costs and narrowing the bid-ask spread (Flammer, Toffel, & Viswanathan, 2021;Ilhan, Krueger, Sautner, & Starks, 2023). ...

In Zusammenarbeit mit Lieferbetrieben und NGOs können Beschaffungs-und Forschungsprojekte zur Reduktion von Umweltbelastungen sowie von negativen Sozialwirkungen und Auswirkungen auf Tierwohl in den Lieferketten durchgeführt werden.

... Recent research found that shareholder pressure positively and significantly influences ESG disclosure [34]. Firms that voluntarily reveal climate change risks following ecological shareholder activism receive a better post-disclosure valuation, implying that investors value values transparency about firms' exposure to climate change risks [55]. [56] research also indicates that shareholders' pressure significantly influences environmental information disclosure. ...

... All over the world, regulatory authorities face the same problem: It is impossible to control everything (Blanc 2012). Despite the billions in annual regulator budgets (European Court of Auditors 2020; US 2021), each regulator has limited resources, and most have a budget sufficient to inspect only a small part of the regulated entities (Johnson et al. 2020). As an alternative to overcome this limitation, risk-based regulation is widely discussed in international publications. ...
