Social capital of entrepreneurs and small firm performance: A meta-analysis of contextual and methodological moderators

► We conduct a meta-analysis on the performance effects of entrepreneurs' social capital. ► Network diversity has the largest positive effect on small firm performance. ► Effect sizes of weak ties are smaller than those of structural holes. ► Social capital's effects are moderated by firm, industry, and country characteristics. ► Effect sizes depend on the network and performance measures that are used.
