Efforts to leverage peer effects by changing assignment have often fallen short due to endogenous peer choice. To address this, I build a two-part model: agents form networks via continuous linking decisions; conditional on realized networks, outcomes are determined. I provide results on identification of both parts of the model. Using data from a randomized study in India, I estimate the model, assess its performance in out-of-sample prediction, and simulate outcomes under preferential assignment rules. This paper contributes new methodology for identifying effects of alternative assignments in the presence of network endogeneity, as well as identification of network formation models.

The Sustainable Development Goals set a triple educational objective: improve access to, quality of, and gender equity in education. This paper documents the effectiveness of a multifaceted educational program, pursuing these three objectives simultaneously. Using an experiment in 229 schools in rural Rajasthan (India), the study measures the effects of the program on students’ school participation and academic performance over two years, while also examining heterogeneous impacts across gender and initial learning ability. It finds that the program increased student enrollment, with the largest effects among girls (7.2 percent in the first year, 12.8 percent in the second). There were large learning gains of 0.329 standard deviations (SDs) in the first year and 0.206 SDs at the end of the second year. The learning component of the intervention targeted both boys and girls – boys and girls benefited equally from the program in terms of test score gains.

The Policy Research Working Paper Series disseminates the findings of work in progress to encourage the exchange of ideas about development issues. An objective of the series is to get the findings out quickly, even if the presentations are less than fully polished. The papers carry the names of the authors and should be cited accordingly. The findings, interpretations, and conclusions expressed in this paper are entirely those of the authors. They do not necessarily represent the views of the International Bank for Reconstruction and Development/World Bank and its affiliated organizations, or those of the Executive Directors of the World Bank or the governments they represent.
