CSR performance and the cost of debt: does audit quality matter?

摘要

Purpose - This study aims to shed light on the effect of corporate social responsibility (CSR) on the cost of debt. It also investigates whether audit quality affects the cost of debt incurred by socially responsible firms. Design/methodology/approach - Based on a sample of French non-financial companies over the period 2005 to 2016, this paper uses panel data regressions. This paper re-estimates the model using Newey-West standard errors and the weighted-least-squares method. For further robustness, this paper runs instrumental variable regressions using the two-stage instrument variable method (two-stage least square). Findings - The results show a negative relationship between CSR performance and the cost of debt, suggesting that financial institutions are likely to apply preferential costs for socially responsible firms. Financial institutions reward socially responsible companies as they recognize the potentiality of CSR to reduce firm risk and enhance its reputation. The findings also show that the perceived audit quality, along with CSR performance, are relevant to banks in the pricing of debt. The incremental audit quality, attributable to audits by the Big 4 auditors, decreases the cost of debt for CSR firms. Big 4 auditors are expected to, simultaneously, play information and insurance roles, thereby enhancing the firm risk profile. The results are robust to alternative audit quality measures (i. e. audit fees). Practical implications - This study has important implications for managers and banks. Managers will be able to understand the effect of CSR on financing costs with relevant implications for strategic financing planning. Firms are also encouraged to signal their commitment to maintain a high-level quality reporting and reduce agency costs through their expenditure in auditing (i.e. hiring a large well-known audit firm). Moreover, this study sensitizes banking institutions to encourage the concept of socially responsible finance and consider soft information (i.e. involvement in societal issues, corporate citizen, trustworthiness, integrity and non-opportunistic behavior), as part of the credit decision-making and debt pricing process. Originality/value - This study extends the literature on CSR and the cost of debt. Unlike prior studies, this paper focuses on the debt-pricing effects of audit quality for CSR firms. Audit quality is deemed to be an important governance feature that is likely to constraint opportunistic behaviors (i.e. CSR diversion) and play information and insurance roles to lenders. Audit quality (perceived or real), along with CSR performance, are associated with lower costs of debt.
