The United Nations University World Institute for Development Economics Research (UNU-WIDER) is requesting research proposals on the World Income Inequality Database (WIID) project. Proposals for original research that speak to the core themes of this project and offer strong empirical, methodological, or theoretical contributions will be considered. This project aims to better understand inequality — how it varies, why it varies, and what the implications of this might be — and to offer new frameworks that provide insight into how to address it. It maps empirical patterns and trends in inequalities and builds our understanding of inequality as both an outcome and a causal variable.

The institution is seeking to commission research papers from researchers working in inequality, income distribution, welfare, and related fields who would like to contribute to the project. As part of the project, researchers will be asked to take part in a workshop tentatively scheduled for June 2022. Researchers may also be invited to present their research at a WIDER Development Conference on inequality to take place tentatively in October 2022.
