	abstract={Using data from Spanish Social Security records, we investigate the returns to experience in different flexible work arrangements, including part-time and full-time work, and permanent and fixed-term contracts. We use a trivariate random effects model which consists of a three-equation system that is estimated simultaneously by Markov Chain Monte Carlo techniques. Our results indicate that there is a large pay gap for working part-time which persists many years after having resumed full-time work. We also find that working part-time involves lower returns to experience than standard full-time employment and thus a substantial negative wage differential for those employed part-time accumulates over time. Finally, we find that heterogeneity exist by contract type and motherhood status.},
