Returning to Work: Older Adults' Labor Force Participation and Health Status
- This study investigated the effects of labor force participation on the physical and mental health of older adults, using the implementation of the provincial-level Regulations on the Protection of the Rights and Interests of the Olderly as an entry point and applying the control function method to address endogeneity. The results indicate that the labor force participation of older adults improved their physical health significantly but had no significant effect on mental health. The positive effect on physical health was stronger for women, urban residents, those with lower education levels, and those with health insurance. Labor force participation operated through income effects and health behavior channels but no evidence was found for a social support channel. These results suggest that removing institutional barriers and empowering older adults can help to address the challenges of an aging population and promote a healthier China.
Inventors in the top management team: How position shapes corporate innovation
研究领域： Inventor executives are important organizers and promoters of corporate innovation. This paper constructs a database of inventor executives in Chinese listed companies by utilizing data on corporate patent inventors and executives' personal resumes. Using data from 2008 to 2022, we investigate the association between inventor executives and corporate innovation. The results indicate: (1) Hiring inventor executives leads to higher innovation growth for firms; (2) The underlying four key mechanisms are signaling effects, R&D investment, executive incentives, and social capital. (3) Inventor CEOs, chairmen, CFOs, and junior executives all boost firm innovation, though the mechanisms through which they operate vary; (4) Inventor executives demonstrate greater innovation-stimulating effects in SOEs than in non-SOEs. This paper introduces a new method to identify internal inventors within companies and further explore their impacts on corporate innovation.
