Multiple-job holding is an important labour market phenomenon. In this article, we examine individuals' motives for multiple-job holding. Specifically, we estimate an empirical model of the motivation for moonlighting assuming that individuals hold a second job for either financial or for nonpecuniary motives. Our results contribute to a better understanding of multiple-job holding. We find that multiple-job holding is used by individuals as a way to deal with the financial difficulties or the increased financial commitments in their household. Individuals are more likely to moonlight for money in the early stages of their adult life. Finally, individuals with more labour market experience are more likely to moonlight for pecuniary than nonpecuniary reasons.
