We analyze the retirement behaviour of married couples using a new bi-variate proportional hazard model. This model generalizes the traditional univariate duration analysis to include a family-wide joint retirement process that induces both spouses to retire at the same time. The model is...

We estimate an equilibrium search model with productivity dispersion between markets and structural unemployment, using Danish data. For women, structural unemployment is relatively more important than frictional unemployment, but for men, frictional unemployment is most important. Overall,...

The homogeneous search equilibrium model of Mortensen (1990) and Burdett and Mortensen (1998) is extended to allow on-the-job wage growth. The extension allows an improved empirical fit to the cross-section wage distribution. The estimation problem is nonregular but tractable. Estimated...

Orthogeodesic models admit marginal local cuts and therefore separate inference on subparameters is asymptotically justified. Doubly-flat orthogeodesic models admit local cuts marginally and conditionally. Two important empirical models for panel data are used to illustrate this property and...

A new class of regression type models termed essentially linear models is proposed. The class is characterized by geometric considerations. Within the class the distribution of the maximum likelihood estimator is easily approximated by a natural extension of the p-formula even though the MLE...
