In this paper we suggest an alternative approach to testing for the dual structure of the labour market. The novelty of the suggested approach is that rather than considering wage determination we concentrate on the turnover. To perform the test we suggest using a latent class count data...

We introduce different skill groups and production functions into the Burdett- Mortensen equilibrium search model. Supermodularity in the production process leads to a positive intrafirm wage correlation between skill groups. Theory implies that increasing returns to scale can lead to a unimodal...

We demonstrate that non-monotone behaviour of the right tail of earnings density may lead to the fact that nonparametric estimation of the Bontemps et al. (2000) equilibrium search model with employer heterogeneity does not yield consistent estimates. We propose an easy way of checking whether...

The distribution of unemployment duration in our equilibrium matching model with spell-dependent unemployment benefits displays a time-varying exit rate. Building on Semi-Markov processes, we translate these exit rates into an expression for the aggregate unemployment rate. Structural estimation...

We introduce skill groups and different production technologies into the Burdett-Mortensen model of on the job search. Supermodularity of the different skill groups in the production process leads to a positive intra-firm wage correlation between skill groups. Increasing returns to scale allow...
