Key Figures

Entitlement and Deprivation Measurement era

Greg J. Duncan [1], affiliated with Northwestern University [3] and Syracuse University [4], was a leading figure in the Entitlement and Deprivation Measurement era. His work on The Effects of Poverty on Children [7] (1997) and Has Children's Poverty Become More Persistent? [8] (1991) helped define how poverty affects child development and its persistence, driving the era’s emphasis on multidimensional thresholds and urban–rural and demographic considerations. Jeanne Brooks-Gunn [2], associated with Harvard University [5] and Johns Hopkins University [6], contributed to this era’s poverty research. Her contributions center on The Effects of Poverty on Children [7], illustrating early childhood contexts as key determinants of poverty trajectories and legitimizing the shift toward institutionally standardized multi-dimensional measurements.

Multidimensional Poverty Dynamics era

Paul Collier [1], associated with Yale University [3] and Imperial College London [4] in this era, contributed to the study of multidimensional poverty dynamics. His key contribution in this era centers on The bottom billion [7], which highlights why the poorest countries fail and informs policy responses to multidimensional deprivation. Ravi Kanbur [2], associated with Cornell University [5] and Columbia University [6] in this era, contributed to understanding poverty dynamics and policy evaluation. World development report 2000/2001 : attacking poverty [8] framed poverty as a multidimensional, temporally-aware policy problem, shaping approaches to distributional and temporal heterogeneity in this era.

Policy Targeting and Standardization era

Yansui Liu [1] is a scholar active in the Policy Targeting and Standardization era (2014-2023), with affiliations across Huazhong Agricultural University [3] and Nanjing Agricultural University [4]. His key contributions in this era include examining spatio-temporal patterns of rural poverty in China and proposing targeted poverty alleviation strategies, as in the 2017 paper Spatio-temporal patterns of rural poverty in China and targeted poverty alleviation strategies [7], and the 2016 Realizing targeted poverty alleviation in China [8], which framed diagnostics for cross-country targeting and policy design. Augustin Kwasi Fosu [2] is a scholar with affiliations across University of Oxford [5] and University of Manchester [6] contributing to global poverty research in this era. His single era paper Growth, inequality, and poverty reduction in developing countries: Recent global evidence [9] synthesizes growth-poverty dynamics and informs policy targeting and standardization.
