This paper examines unemployed workers' willingness to move for work and its relationship to their unemployment duration in Spain. We use a hypothetical question in the Spanish Labour Force Survey: 'Would you accept a jot, offer which implied a change of residence?' The main finding is that, while family responsibility, age and education are important in determining individuals' migration willingness, the duration of unemployment does not show any significant effect, even after controlling for unobserved fixed individual heterogeneity. However, the significant improvement in migration willingness after the exhaustion of unemployment benefits (or when other household members become unemployed) suggests that economic incentives could play an important role in increasing worker mobility. We also find that job-finding probability is significantly higher among those with positive migration attitudes than among others.
