The Role of Equalized Parental Leave in Enhancing Audit Quality

Summary

Ryan C. Ballestero's 2026 research paper, "The Role of Equalized Parental Leave in Enhancing Audit Quality," published in Accounting Horizons, investigates the impact of parental leave policies on the quality of auditing services. The study focuses on how the implementation of equalized parental leave policies within audit firms influences audit quality. Ballestero utilizes a difference-in-differences methodological approach to analyze this relationship, a technique well-suited for evaluating the causal effect of policy changes that occur at different times across different entities. This method allows for a robust assessment by comparing changes in audit quality for firms that adopt such policies against those that do not, while controlling for other confounding factors. The research specifically acknowledges that the adoption of these leave policies is an audit firm-level decision, indicating a focus on organizational policies and their subsequent effects on professional outputs. The key finding of the paper is that the presence of equalized parental leave policies is associated with higher audit quality. This suggests that such policies may contribute to a more stable, experienced, and motivated workforce, which, in turn, positively influences the rigor and reliability of audits. The implications of this study are significant for both academic literature and practitioners. It contributes to the understanding of firm culture's importance in professional services and expands the broader literature on the economic impacts of paid family leave. For audit firms, the research highlights equalized parental leave as an effective talent management strategy, potentially aiding in employee retention, fostering a more inclusive work environment, and ultimately enhancing the firm's overall audit quality and reputation. The data used in the study are available from public sources, ensuring transparency and reproducibility.
