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 develop and estimate a structural non-stationary econometric model of job search with monitoring of search effort and sanctions. The earliest moment of the first monitoring is announced several months in advance and the judgement of the caseworker is based on cumulated search effort over a...
