Suggestions on applied research on the topic:
There is a huge literature of empirical application of unidimensional inequality and poverty measures to different countries and regions. The World Bank has produced a lot of applied research on these topics. The most common measures such as the FGT Indices as well as the Gini Coefficient are periodically estimated and released through the World Development Indicators. There is also a big amount of World Bank Policy Research Working Papers done on specific countries. Two recent World Bank Development Reports are worth noting: the World Development Report 2000/2001, Attacking Poverty: Opportunities, Empowerment and Security and the World Development Report 2006: Equity and Development. For all these information please visit The World Bank website. These documents can be found either on ‘Data and Research’ or on ‘Publications’.
