Entrepreneurship research is concerned with identifying and exploiting entrepreneurial opportunities, enabling factors of entrepreneurial activity, and the complex conditions under which entrepreneurial behavior occurs. To address this complexity, the Entrepreneurship Research Group uses a variety of different approaches. We work conceptually and empirically with qualitative and quantitative techniques and use a wide variety of methods to produce knowledge. In principle, every entrepreneurial phenomenon is of potential interest for the research group - if entrepreneurship is opportunity-driven, then research on entrepreneurship must be as well.
