In this paper we argue that univariate mixed models are not appropriate in measuring unobserved heterogeneity in studying IPOs survival in the aftermarket. We extend the methodology used up to now by developing a random effects model to account for heterogeneity among industries. Our results indicate that the proportion of early failed firms is rather negligible and the effect of frailty depends on the overall hazard rate.
