This is a really interesting talk from Vikram Bhalla from back in 2015. 

He points out that whilst there is academic research around family enterprises in general, there was little geographical differentiation afforded to the research. 

Therefore he conducted his own, and you may be surprised by his findings. 

This shows us that there is rarely an 'out of the box' solution that all family businesses should adopt and often what works for one, does not for another.
