Abstract
This article extends research on family firm social capital by examining two components of family firm social capital, organizational efficacy and interorganizational trust, and their influence on performance in family and nonfamily firms. Using a sample of 157 family and nonfamily suppliers to a University, we find that suppliers' organizational efficacy and trust in the buyer positively predict performance in family and nonfamily firms. Contrary to expectations, there were no significant differences between family and nonfamily firms in the level of organizational efficacy and interorganizational trust. We also find that the interaction of organizational efficacy and interorganizational trust predicts performance in family firms. Based on these findings, we discuss implications for theory development and provide suggestions for future research. (C) 2013 Elsevier Ltd. All rights reserved.
