Following recommendations from a Congressional panel tasked with improving nonprofit governance, in 2005, the IRS began requiring nonprofit organizations to report the existence of family and business relationships among board members. We study these relationships and find they are common in U.S. nonprofits and not associated with assumed detrimental effects. Rather , we find that organizations reporting relationships between board members have less management spending, lower levels of excess cash, and better reporting quality, while receiving higher contributions. Further, using detailed disclosure information, we find that while both business and family relationships among board members are associated with less administrative spending, lower levels of excess cash, and higher contributions, family relationships are also associated with better reporting quality. Overall, our evidence supports the idea that relationships among board members do not harm nonprofit organizations.
