Book excerpt: Why do some countries have a vibrant nonprofit sector while others do not? Nonprofits in Crisis explores the theory of risk as a major mechanism through which economic development influences the nonprofit sector. Nuno S. Themudo elaborates this idea by focusing on Mexican nonprofit organizations, which operate and strive to survive in a risky environment. The study of these nonprofits generates broader lessons about philanthropy and the nonprofit sector that complement wider cross-national statistical analysis.
