This study identifies evidence of the influence of diversification and leverage on the financial performance of Brazilian and Mexican family businesses. It analyzes 102 Brazilian and 71 Mexican publicly traded family companies. Data analysis uses ordinary least squares regression in Stata. The results indicate that Brazilian family businesses have a higher return on assets when diversifying their products or services. When diversifying international markets, Brazilian companies present a lower return on assets and return on equity. For Mexican companies, international diversification derives a higher return on assets and return on equity. In addition, results show that leverage moderates the relationship between diversification and performance both for Brazilian and Mexican family businesses. The study contributes to the current literature by investigating that diversification improves business performance and that leverage is a significant element in intensifying the benefits of this strategy in the performance of family businesses. The study also emphasizes that diversification can be useful to address market difficulties and imperfections in unstable scenarios, such as when it is targeted to planned performance and considers financial conservatism in family companies.

There has been very little research on family businesses (FBs) in Iran. Taking an institutional point of view, this article, based on a survey conducted in Iran, demonstrates that since the 1979 revolution FBs in Iran have been key intermediaries between political pressure from the top and societal trends from below. FBs in Iran since the revolution can be considered as a perfect mode of coordination reflecting “capitalism from below.” Based on unconditional support among the family members, they are perfectly adapted to the low-trust environment in Iran since the revolution. As a mode of coordination, the family business was also essential in protecting the modernization of Iranian society in promoting the role of women and the value of competency. It was also a mode of coordination which enabled FBs to protect their property rights which were threatened by a predatory state.

Mentoring and coaching practices are helping businesses grow by supporting the development of their human capital. Family businesses have a unique atmosphere and distinctive features that make it especially important to discover whether mentoring and coaching affect their performance. We have used a resource-based vision and knowledge-based vision to analyse this relationship using structural equation methodology in a sample of 630 companies. The results show that there is a direct relationship between mentoring and coaching and the performance of family businesses.

The authors investigated generativity – the concern in establishing and guiding the next generation – as a mediator of the relationship between family business owners' age and succession in family businesses. Data came from 155 family business owners in Germany from different industries between the ages of 26 and 83 years. Results showed that age was positively related to generativity, and that generativity, in turn, positively influenced an objective measure of family succession. Generativity fully mediated the positive relationship between age and family succession. The findings suggest that generativity is an important psycho-social construct for understanding ageing, careers and succession in family business settings.
