46Variable Population Poverty ComparisonsJournal of Development Economics 98 (2): 238-241. 2012.This paper demonstrates that the property of Replication Invariance, generally considered to be an innocuous requirement for the extension of fixed-population poverty comparisons to variable-population contexts, is incompatible with other plausible variable- and fixed-population axioms. This fact raises questions about what constitutes an appropriate headcount assessment of poverty, in terms of whether one should focus on the proportion, or the absolute numbers, of the population in poverty. Thi…Read more

49Counting the poor: An elementary difficulty in the measurement of provertyEconomics and Philosophy 18 (2): 277-285. 2002.This note suggests that the exercise of measuring poverty in a society is greatly aided by clarity on precisely what one means by “the extent of poverty”. The latter concept may refer to the extent of poverty normalized for population size, or to the extent of poverty not so normalized. Absence of clarity on this distinction – which is both simple and non-trivial – could lead to rather straightforward problems of coherence and consistency in the measurement of poverty.

8The Iniquity of Money-Metric Poverty in IndiaBasic Income Studies 12 (1). 2017.This paper is concerned to make three points about money-metric poverty in India: first, that the standard poverty-line approach to measuring poverty considerably underestimates poverty, and that the particular protocols by which India’s official poverty lines are determined are arbitrary and misleading; second, that a view of poverty in which the achievement of a satisfactory level of income is seen as a valuable end in itself, and which is captured in something like Kaushik Basu’s ‘quintile in…Read more
