Entrepreneurship and Innovation in Family Firms Family firms account for roughly 88% of all firms in Switzerland. In a survey from 2005, the CFB-HSG found that 36% of all family firms were founded before 1945. This leads us to the question: How do family firms manage to be successful over several generations? What are the antecedents of long-term success? How to counter inertial pressures, stagnation and decline? These as well as further questions are in the center of our research activities in the field of entrepreneurship and innovation in family firms: • Transgenerational Entrepreneurship • Psychological Ownership • Innovations in Family Firms • International Research Project GUESSS Selected Publications Bird, Miriam & Wennberg, Karl (2016) Why Family Matters: The Impact of Family Resources on Immigrant Entrepreneurs’ Exit from Entrepreneurship.
