Abstract

Measures of social difference such as the Ethnolinguistic Fractionalization Index (ELF) and Polarization are commonly used proxies for community heterogeneity. They are used to “explain” collective outcomes ranging from voluntary contributions in elementary schools to civil wars. This essay reviews this literature in the face of new research on identity and collective outcomes. I argue that methods of social classification often seriously mis-measure identity and difference and that poverty rather than heterogeneity is often the source of community failures.

We study how information to parents and schools on the performance of primary school children can improve learning outcomes in an environment where public and private schools co-exist. Contiguous village councils in the Indian state of Rajasthan are randomly assigned to either a control or one of four treatment groups in which student report cards on curriculum-based tests are provided to schools, parents or both. We find no changes in academic performance in public schools.

In this paper we show that local redistribution of educational resources via teacher transfers between neighboring public schools can improve equity in access to teachers. Transfers from teacher surplus schools to deficit schools within a 10 km radius in Haryana, a state of India for which we have geo-coded location of schools in 2013, enables 19 percent of deficit schools to meet the minimum requirement. We use the mandated norms in the Right to Education Act in India, to define deficit and surplus schools.

How does information on environmental risks obtained by individuals in developing countries affect environmental quality? The literature reveals that for issues like water quality and pesticides, information affects individual behavior and risks are reduced through individual action. However, even if information were to become widely available in developing countries, unless regulation is also strengthened, environmental risks will remain at high levels relative to developed countries.
