Collaborative research: Career Lifecycles of Enterprising Workers in R&D Intensive Industries

创业者建立自己的职业生涯，不断做出选择，要么留在他们创建的初创企业，要么离开从事连续创业，要么退出有偿就业，要么独自一人，作为一个独立的小团队的一部分，或者作为一个成熟公司收购的完整公司的一部分。这些选择是由经验和限制因素决定的，反过来又影响到后来的职业选择和经济结果。 通过追踪创新人员在企业内部和企业之间的职业历史，更多地关注人力资本动态，可以更深入地了解经济动态。对影响创业者职业选择的因素进行审查，可以为科学和创新政策提供信息，以促进知识的创造和传播。美国人口普查局纵向雇主-家庭动态（LEHD）项目提供了几乎普遍的覆盖范围，允许构建1991-2008年18年期间研发密集型行业中有进取心的个人的职业历史。 研究的重点是这些人的命运后，创业活动，通过检查个人退出不同类型的新企业后采取的路径，并通过检查不同的创业经验的创业环境外的可转移性。 家庭组成限制了地域流动性，而地域流动性反过来又决定了有进取心的个人如何通过流动性和创业精神建立自己的职业生涯。 这些研究共同探讨了创业活动的重要个人前因和后果。

Enterprising individuals build their careers, continuously making choices between staying at the start-ups they create, leaving to engage in serial entrepreneurship, or exiting into paid employment, either alone, as part of a small independent team, or as part of full company acquired by an established firm. These choices are shaped by experiences and constraints and, in turn, affect subsequent career choices and economic outcomes. Greater attention to human capital dynamics by tracing career histories of innovative personnel within and across firm boundaries may provide richer insights into economic dynamism. An examination of factors that impact enterprising workers' career choices can inform science and innovation policy to promote knowledge creation and diffusion. The US Census Bureau Longitudinal Employer-Household Dynamics (LEHD) Project provides near universal coverage that allows the construction of the career histories of enterprising individuals in R&D intensive industries across the 18 year time period from 1991-2008. The research focuses on the fates of these individuals after entrepreneurial activity by examining the paths that individuals take after exiting new ventures of different types and by examining the transferability of different entrepreneurial experiences outside of the entrepreneurial context. Family composition constrains geographical mobility which in turn shapes how enterprising individuals build their careers through mobility and entrepreneurship. Together the research explore important individual antecedents to, and consequences of, entrepreneurial activity.
