We derive the asymptotic sampling distribution of various estimators frequently used to order distributions in terms of poverty, welfare and inequality. This includes estimators of most of the poverty indices currently in use, as well as estimators of the curves used to infer stochastic...

Presently, conditions ensuring the validity of bootstrap methods for the sample mean of (possibly heterogeneous) near epoch dependent (NED) functions of mixing processes are unknown. Here we establish the validity of the bootstrap in this context, extending the applicability of bootstrap methods...

In the context of multivariate regression (MLR) and seemingly unrelated regressions (SURE) models, it is well known that commonly employed asymptotic test criteria are seriously biased towards overrejection. in this paper, we propose finite-and large-sample likelihood-based test procedures for...

The paper proposes and applies statistical tests for poverty dominance that check for whether poverty comparisons can be made robustly over ranges of poverty lines and classes of poverty indices. This helps provide both normative and statistical confidence in establishing poverty rankings across...

An axiomatic approach is used to propose a measure of extreme poverty which is not only multidimensional in nature, but also recognizes the fact that there are interaction effects between different deprivations, and that the length of time during which deprivations are felt may also have a...

Income variablity reduces social welfare if individuals are risk averse, and it is likely to increase inequality if poorer households are more vulnerable to shocks. Using a simple method to estimate risk-adjusted measures of inequality and welfare and wage data from Mexico, this note shows that...

The Gini income elasticity has been used to assess the impact of marginal proportional changes in income from a given source on inequality in total income. This note extends the methodology to take into account income variability.

Commodity producers in Africa often bene?t from guaranteed and relatively stable prices for their crops. This paper shows how to estimate the required increase in crop price necessary to o¤set the higher risk for farmers that price liberalization would entail due to large variations over time...

In this paper, we suggest a framework for the analysis of ethnic polarization. This framework allows for the measurement of ethnic or religious polarization. We apply our measure to Ivory Coast and find a surprising result as the ethnic polarization decreased in years preceding the conflict in...
