An Empirical Model of Sectoral Movements by Unemployed Workers

Using Canadian data, the author investigates the relationships among sectoral mobility, unemployment spells, and total unemployment. Recent North American evidence suggests that incidence shifts toward high wage-high tenure workers may increase equilibrium unemployment through decreasing sectoral mobility and increasing spells. Using a multiple spell transition model, the author finds that, while shifts toward such workers may have these effects, composition changes that lead to higher mobility can also increase unemployment. A further investigation into the relative roles of mobility and spell lengths in driving total unemployment indicates that the influence of the former is comparatively small.
