Measuring the Labor Market Effects of Social Capital: A literature review and research strategy of dealing with the endogeneity problem

内生性问题是社会科学定量分析面临的重要挑战之一。如何通过不同的模型识别策略来消减内生性问题,判定因果关系,成为了近来西方社会资本研究领域的前沿议题。本文围绕社会资本的劳动力市场效应,从“使用社会关系”、“使用了的社会资本”和“可使用的社会资本”这三条主线,重点回溯了相关研究中的内生性问题和模型识别策略。最后,本文提出今后社会资本实证研究中模型设置、数据搜集纵向跨度、横向跨度、外生变量挖掘、研究假定说明和复制性研究等六大努力方向。

A major challenge for quantitative research in social science is the endogeneity problem. How to exploit various model identification strategies to alleviate estimation bias to identify causality has recently been a cutting-edge research field in studies on social capital. This paper reviews the endogeneity problem and model identification issues in existing studies on the labor market role of social capital，following three research lines focusing on using contacts，used social capital and accessed social capital. Improving model specification and data collection，exploiting exogenous variables， clearly specifying working assumptions and replication studies are called for.
