How family involvement affects business results? The present work demonstrates how 'familiness' is related to performance in Mexican family firms. We proposed three dimensions of familiness (Process, Human and Organizational Resources) from a perspective based on the Resource Based View and the Social Capital Theory. In addition, our intention is to look for the strongest relationship among those dimensions to show which one has more influence on the performance of the family firms. We interviewed a sample of 194 Mexican family firms and we discovered that they have many characteristics in common despite the region of Mexico they are located. We also used some control variables such as the size of the companies, the sector in which they have operations (commerce, services or manufacturing) and the age of the companies, in order to analyze the sample from different points of view.
