Abstract: Using medical insurance (MI) to shift employees' health risks outside is an important risk management tool for modern firms. Existing studies usually treat firms' contributions to employees' MI only as a labor cost. However, contributing to MI also has indirect benefits, such as improved labor productivity and R&D innovation, which consequently increase corporate value. This paper studies the impact of firms' MI contributions for employees on corporate value, using social insurance collection system reform in China as a natural experiment. Results show that, first, the reform increases firms' contributions to employees' MI funds. Second, the increase has a positive impact on firms' market-to-book ratio. These effects can be explained by enhanced labor productivity, firm efficiency, and innovation. Heterogeneity analysis suggests that the effects are more pronounced for firms in high R&D industries, areas with high pollution, or areas with better medical and labor supplies.
