摘要:In this paper we analyse the role that Social Security wealth and incentives play in the transition to retirement in Spain . We use the labour records and other relevant information contained in a newly released database [ Muestra Continua de Vidas Laborales (2006)] to construct incentive measures stemming from the Social Security provisions in relation to retiring at old age and investigate the role played by such incentives and by other socio-economic variables on the retirement hazard. We compute the effects of the reform that took place in 2002, which made the requirements to access a pension stricter in general. We carry out a dynamic reduced-form analysis of the retirement decision using a duration model. Our results show that both the pension wealth and substitution effects have a significant role on retirement decisions, but that the latter has less relevance since the reform introduced in 2002.
