Abstract
Trust is an informal mechanism of governance that seems to work in family businesses differently from other types of companies. This conceptual paper analyzes the impact of internal trust on the competitiveness of firms over time. To this end, we introduce different modes of intra-firm trust, develop a set of research propositions, and introduce a stage model on the development of trust in family businesses over time. By comparing family and non-family businesses, we discuss how the differences may influence the competitiveness. The paper advances research by a holistic approach of trust and a multidimensional view of trust.
