Two important lines of research have shaped our understanding of the ability of communities to engage in collective action. The first proposes ethnic division as a key determinant, with more ethnically-heterogeneous countries having worse economic performance and fewer public goods. The second focuses on social capital as a major determinant of the ability to engage in collective action. We expect trust among community members, a widely-used measure of social capital, to be an important and positive determinant of school quality.
