Jaramillo, M. y Campos, D. (2023). Revisiting the stepping-stone hypothesis: transitions from temporary to permanent contracts in Peru, International Labour Review, 162(2), 199-221.

This study seeks to gauge the extent to which temporary contracts function as stepping stones to permanent contracts and to distinguish intrafirm from interfirm contract conversions. Using 2012–2016 data from a Peruvian matched employer–employee database, the authors propose several measures of contract conversion and estimate duration models. Their findings show that only 7 per cent of fixed-term contracts are converted and that about half of the conversions occur in the same firm.
