Educational Mismatch and Trade Union Membership
研究工会会员身份与教育错配的关系，发现工会会员与过度教育负相关、与教育匹配正相关，尤其对核心会员群体影响显著。
ABSTRACT We hypothesize that trade unions assist their members in avoiding situations of educational mismatch. We test this hypothesis using data from the German Socio‐Economic Panel and find that trade union membership is negatively associated with overeducation and positively associated with the likelihood of being educationally matched. These correlations are especially pronounced among core groups of members. Our findings suggest that a strong trade union presence within these groups helps avert the adverse consequences of overeducation and educational mismatch. We observe no systematic linkage between union membership and undereducation.
