本文建立了一个劳动力市场模型，考察了社交网络作为工作信息渠道对劳动者与企业不匹配程度的影响。正式市场在产生良好的匹配的效率相比，社交网络。假设工人之间的链接代表了偏好关系：工人们相互推荐任何类型的工作，而不管最终匹配的质量如何。这项研究表明，随着连接相似代理（同质性）的纽带比例增加，失配水平降低。如果这一比例足够高，那么对于任何市场效率水平，网络都能以高于正规市场的速度提供良好的匹配。在这种情况下，在有社交网络的经济体中，不匹配程度低于工人不使用社交网络寻找工作的情况。因此，社交网络的存在可以减少不匹配，尽管偏袒。通过不同的搜索方法可获得的工作的预期工资的失配创建的影响进行了讨论。
A labor market model with heterogeneous workers and jobs is provided to investigate the effects of social networks as a job information channel regarding the level of mismatch between workers and firms. The efficiency in producing good matches of the formal market is compared to that of social networks. It is assumed that links between workers represent favoring relationships: workers recommend each other for any kinds of jobs, regardless of the quality of the resulting match. This study shows that as the fraction of ties connecting similar agents (homophily) increases, the level of mismatch decreases. If this fraction is sufficiently high, networks provide good matches at a higher rate than the formal market, for any efficiency level of the market. In this case, the mismatch level is lower in economies with social networks than it would be if workers did not use social contacts for job search. Hence, the presence of social networks can reduce mismatch despite favoritism. Implications of mismatch creation for the expected wages of jobs obtainable through different search methods are also discussed.
