This book applies benefits theory to the financing of nonprofit and other social purpose organizations. Individual chapters are devoted to organizations primarily reliant on earned income, gifts, government support and investment income, respectively, as well as organizations that are highly diversified in their sources of operating support. The book is intended to guide managers and leaders towards finding the best mix of income sources for their organizations, to help educate future managers about resource development and to stimulate additional research on the financing of nonprofits and other forms of social enterprise.
