Sectoral Shifts and Canadian Unemployment
用加拿大季度数据检验Lilien的假说，发现外生的部门间就业转移对总失业率没有显著影响，并扩展了模型以考察地区劳动力市场刚性和行业转移与总经济活动的关系。
In this paper Lilien's (1982) hypothesis that sectoral shifts in employment raise aggregate unemployment is tested using Canadian quarterly data. Lilien's framework is extended to investigate regional labour market rigidities and to distinguish between industry shifts that are correlated with changes in aggregate activity, and those which are exogenous to the overall level of activity. The robustness of the results to various changes in model specification is also investigated. I find that in Canada exogenous shifts in employment between sectors do not have a significant effect on the aggregate unemployment rate.
