Productivity and age: Evidence from work teams at the assembly line

We study the relation between workers’ age and their productivity in work teams, based on a new and unique data set that combines data on errors occurring in the production process of a large car manufacturer with detailed information on the personal characteristics of workers re-lated to the errors. We correct for non-random sample selection and the potential endogeneity of the age-composition in work teams. Our results suggest that productivity does not decline at least up to age 60.
