Do Postsecondary Training Programs Respond to Changes in the Labor Market?
本文利用美国人口普查和最大社区学院系统的数据，分析了过去几十年职业培训项目是否跟上了劳动力市场职业结构的变化，发现职业的就业份额每增加一个百分点，其社区学院毕业份额约增加半个百分点，且主要由学生需求驱动。
This paper analyzes whether postsecondary training programs have kept up with shifts in the occupational structure of the labor market over the past decades. I compare long-term trends in the distribution of employment, degrees, and certificates across occupation groupings using data from the US census and from the nation’s largest community college system. I then estimate that an occupation’s share of community college completions grows by approximately half a percentage point for every percentage point increase in its share of employment. I show that this relationship is primarily driven by increases in student demand rather than by colleges expanding capacity.
