Abstract A fundamental, but overlooked stream of resource-based theory (RBT) is the analysis of combinations of initial heterogeneous resource endowments with homogeneous resources that are acquired in the market. These combinations can generate heterogeneous, specific non-tradable resources, which are a potential source of superior competitive advantage and, hence, performance. In order to operationalize this idea empirically, we analyse the development of internationalization resources (considered a specific category of non-tradable resources) within family and non-family firms. Compared to non-family firms, we argue that family firms are able to combine a particular type of heterogeneous initial resource (i.e. familiness) with homogeneous tradable resources acquired in the market. This question is tested using a panel of family and non-family Spanish manufacturing firms for the period 1990 to 2010. As a result, this study contributes to the literature on RBT, extending previous theoretical and empirical research in this stream.
