The retirement age and the hiring of senior workers
利用挪威2011年养老金改革带来的政策变化，研究发现降低法定最低退休年龄会显著增加企业对老年工人的雇佣，尤其是有病假史和蓝领工人，表明风险规避型企业在退休年龄降低时更愿意雇佣老年工人。
This paper examines the effect of decreasing the distance to the minimum legal retirement age on the hiring of senior workers. Using variation brought about by a comprehensive old-age public pension reform in Norway in 2011, I identify a positive effect on the hiring of senior workers. The results suggest that the increase was mainly caused by a positive shift in the demand for “risky” senior workers (workers with prior sick-leave and blue-collar workers). This lends support to the notion that risk-averse firms are more willing to hire senior workers when the minimum legal retirement age is decreased.
