Does social participation improve cognitive abilities of the elderly?

This paper examines the effect of social participation on cognitive performance using data from a longitudinal survey of the elderly in China. It addresses the problem of endogenous participation by exploiting the variation in changes in social participation that are driven by changes in community service for social activities. The results show that participating in social activities has significantly positive impacts on cognitive function among the elderly. The point estimates indicate that engaging in social activity raises cognitive scores by 29% of a standard deviation.
