Mapping employment dynamics in public agencies with payroll data: A methodological framework with an application to Chile.

This study introduces a novel, replicable methodology for analyzing employment dynamics within public sector agencies, focusing on turnover and staff longevity. The methodology is designed to be generalizable and applicable to diverse national contexts where detailed administrative data is available. Using payroll data from over 325,000 Chilean civil servants (2006-2020), we apply mixed-effects Cox survival models and linear mixed models to examine patterns of employment stability across state agencies.
