Doctoral Dissertation Research: Social Networks and Labor Market Mobility

虽然对劳动力市场中的社会网络和工作流动都有研究，但对这两个重要的社会现象之间的关系研究很少。本论文研究改进项目通过系统考察社会网络结构对劳动力市场流动性的影响来解决这一差距。研究者认为，结构漏洞，定义为网络中的非冗余联系，可以增加：(1)雇员关于“更好的工作”的信息总量，(2)雇主关于潜在雇员的信息，以及(3)雇员获得的信息的有用性。在此基础上，提出了一系列的模型和可检验的假设。数据将从美国电视台经理的人口中收集。具体来说，600名电视台经理将被要求完成一项邮件调查，该调查要求受访者提供社交网络、工作经历和求职时获得的工作信息来源等信息。这项调查将包括那些在1996年换了工作的经理和那些没有换工作的经理。＊＊＊＊

This Dissertation Research Improvement project addresses this gap through systematically examining the effects of social network structure on labor market mobility. The investigator argues that structural holes, defined as non-redundant contacts within networks, can increase the: (1) total amount of information an employee has about "a better job," (2) information an employer has on potential employees, and (3) usefulness of the information an employee obtains. A series of models and testable hypotheses are formulated based on these assumptions. Data will be gathered from the population of television station managers in the United States. Specifically, 600 television station managers will be asked to complete a mail survey which requests information on the respondent's social network, job history and sources of job information obtained when looking for a job. Include in this survey will be mangers who changed as well as those who did not change jobs during 1996. ****
