Are You Rich Enough for A (Single) Family Office

Are you rich enough for a family office? Focusing purely on the financial economics of a family office, we derive the minimum assets under management compatible with the family office’s investment management skills and costs versus the family benchmark alternative as well as its risk aversion. We find that rules of thumb like “the minimum size for a family office is 100 million” can be grossly misleading. Our analysis is equally applicable to deciding on the threshold size for in-house asset management.
