The University of California, Berkeley sends more undergraduate students to economics PhD programs than any other public university. While this fact is surely a function of its size, there may be lessons from the Berkeley experience that others could adopt. To investigate why Berkeley generates so many economics PhD students, the author convened and interviewed two groups: economics student services staff and a self-selected focus group of twelve economics undergraduates who plan to apply to PhD programs. Four factors came up repeatedly in these conversations: math preparation, advanced track for theory courses, research opportunities, and availability of information. A fifth factor was implicit in the conversations: peer effects.  相似文献

This study explores the motivations and opportunity recognition patterns of 30 Israeli social entrepreneurs (SEs) through life story analysis. The majority of participants were motivated by pull factors that included prosocial behaviors based on past or current life events. Others were motivated by push factors, including job dissatisfaction and a search for meaning. Based on grounded theory‐building and sensemaking perspectives, we develop a theoretical process model that links motivations, opportunity recognition, and prosocial activities of SEs. Their experiences created an awareness of unmet societal needs, which led to opportunity recognition and formation of social ventures to help fill the gaps.  相似文献
