The sustainability of start-up firms among formerly wage workers

In this paper we analyse the survival of start-up firms among formerly wage workers in Spain. In particular, we address the question of how long do these workers remain self-employed before entering into unemployment or returning to a new paid-employment, using well-known duration model techniques. Results show that a higher survival rate in self-employment is associated to men, prime-age workers and individuals with higher previous labour turnover. Moreover, longer unemployment spells are found to speed up the rate of transition to non-employment and to reduce that to paid employment. Finally, the probability of exiting decreases with duration in self-employment.
