An Empirical Model of Sectoral Movements by Unemployed Workers
利用加拿大数据，研究失业工人的行业流动、失业持续期与总失业之间的关系，发现高工资高任期工人比例上升可能通过降低流动性和延长失业期推高失业，但流动性增加也可能导致失业上升。
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.
