Regulations, profitability, and risk-adjusted returns of European insurers: An empirical investigation

• We examine the effect of regulations on European insurers’ performance.
• Many regulations have a nonlinear relationship with performance.
• The results are robust to controls for various firm- and country-specific attributes.

This study examines the effect of regulations on European insurers’ profitability and risk-adjusted returns. We find an inverted U-shaped relationship between return on assets and regulations relating to capital adequacy, accounting and auditing requirements, and disclosures to supervisors. In contrast, requirements related to technical provisions have a negative effect on return on assets, and we find no evidence of an association with regulations related to investment and supervisory power. We also find evidence of an inverted U-shaped relationship between a firm's risk-adjusted rate of return and regulations relating to capital requirements as well as corporate governance and internal control. We observe the opposite in the case of technical provisions. These results are robust to controls for various country-specific attributes such as macroeconomic environment, stock market development, overall quality of institutions, and legal origins.
