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

有事业心的个人建立自己的职业生涯，不断地做出选择，要么留在自己创建的初创企业，要么离开从事连续创业，要么退出从事有偿工作，要么独自一人，作为一个小的独立团队的一部分，要么作为被老牌公司收购的完整公司的一部分。这些选择是由经历和制约因素塑造的，反过来又会影响随后的职业选择和经济结果。通过追踪公司内部和跨公司创新人员的职业历史，更多地关注人力资本动态，可能会为经济动态提供更丰富的见解。研究影响创业工作者职业选择的因素可以为科学创新政策提供信息，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）项目提供了近乎普遍的覆盖范围，允许构建研发密集型行业中进取个人的职业历史，时间跨度为1991-2008年的18年。本研究通过考察个体在退出不同类型的新企业后所采取的路径，以及考察不同创业经历在创业环境之外的可转移性，重点关注这些个体在创业活动后的命运。家庭构成限制了地域流动性，这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体前因和后果。

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.
