The main purpose of this article is to examine the role of intangible family resources in the performance of family enterprises in Tanzania. In particular, the article examines the role of information sharing, family patient capital and family labor in firm performance. Using a sample of 163 family firms and the structural equation model of analysis, the findings indicate that family patient capital and information sharing contribute significantly to the performance of firms. With regard to the cost of labor, the study does not show any evidence that lower labor costs improve family firms' performance, most probably because these businesses incur additional labor costs which are not directly linked to the business. Based on the results, it is concluded that the family has an influence on the strategic level of family businesses, thereby contributing to their success.
