Multinomial choice and selectivity
(Discussion Papers;No 264, Working paper, 2000)In this paper we discuss two types of selection problems. The first problem is motivated by labor market analyses such as the estimation of sector-specific wage equations where the sector for which the wages are observed ... -
Non-parametric identication of the mixed proportional hazards model with interval-censored durations
(Discussion Papers;600, Working paper, 2009)This note presents identication results for the mixed proportional hazards model when duration data are interval-censored. Earlier positive results on identication under intervalcensoring require both parametric specication ... -
Using the Helmert-transformation to reduce dimensionality in a mixed model: An application to a wage equation with worker and firm heterogeneity
(Discussion Papers;No. 667, Working paper, 2011)Abstract: A model for matched data with two types of unobserved heterogeneity is considered – one related to the observation unit, the other to units to which the observation units are matched. One or both of the unobserved ...
