The authors investigate whether an equilibrium search model, in which the wage offer distribution is endogenous, is able to describe observed labor market histories. They find that the distributions of job and unemployment spells are consistent with the data, and qualitative predictions of the...

We are interested in estimating the average effect of a binary treatment on a scalar outcome. If assignment to the treatment is exogenous or unconfounded, that is, independent of the potential outcomes given covariates, biases associated with simple treatment-control average comparisons can be...

This paper presents new identification conditions for the mixed proportional hazard model. In particular, the baseline hazard is assumed to be bounded away from 0 and ∞ near t = 0. These conditions ensure that the information matrix is nonsingular. The paper also presents an estimator for...
