How binding are legal limits? Transitions from temporary to permanent work in Spain

Abstract

This paper studies the duration pattern of …xed-term contracts and the determinants of their conversion into permanent ones in Spain, where the share of …xed-term employment is the highest in Europe. We estimate a duration model for temporary employment, with competing risks of terminating into permanent employment versus alternative states, and ‡exible duration dependence. We …nd that conversion rates are generally below 10%. Our estimated conversion rates roughly increase with tenure, with a pronounced spike at the legal limit, when there is no legal way to retain the worker on a temporary contract. We argue that estimated di¤erences in conversion rates across categories of workers can stem from di¤erences in worker outside options and thus the power to credibly threat to quit temporary jobs.Fixed-term contracts, duration models
