Determinantes de la situación laboral en España: trabajar a tiempo parcial frente a otras situaciones laborales

This paper studies the determinants of part time employment in the Spanish labour market. Using a sample of workers taken from the administrative data set Muestra Continua de Vidas Laborales (MCVL), we investigate the determinants of employees' finishing 2007 working part time, under a temporary or permanent contract, in comparison with other labour situations. For that purpose, we define a set of possible labour situations and estimate the determinants of each one using logistic regressions. Estimations were carried out for the whole sample and separately for men and women. The explanatoryvariables introduced in the model refer to former work experiences, such as the types of contracts that each individual has had; last job position, such as professional group and sector of activity; demographic characteristics, such as age; and variables related to the economic context, such as living in a region with a GDP above the Spanish national mean. The paper concludes that part time job determinants differ considerably for women and men, although they have several characteristics in common.
