In the income (or consumption) poverty framework, a relevant open problem is connected with the distinction between poor and non-poor. This is usually done by considering a pre-specified income threshold called poverty line. If the income of an observation unit is lower (higher) than the poverty line, then such an observation unit is poor (non-poor or rich). Unfortunately, this procedure may of...

This paper examines the partial orderings of discrete distributions derived from various poverty indices and sets of welfare functions. The poverty ordering with respect to some index P is the ordering obtained when P ranks consistently over a range of admissible poverty lines. The poverty orderings derived from the headcount ratio, the per-capita income gap and another "distribution-sensitive"...

This paper estimates income gap ratios and Gini coefficients of poor Americans and combines them with official U.S. government poverty statistics to create a new time series of Sen indices of poverty. The effects of growth and other determinants of aggregate poverty are investigated over the period 1961-1996. The results indicate that economic growth affects the Sen index and official poverty h...

BACKGROUND Population health is linked closely to poverty. To assess the effectiveness of health interventions it is critical to monitor the spatial and temporal changes in the health indicators of populations and outcomes across varying levels of poverty. Existing measures of poverty based on income, consumption or assets are difficult to compare across geographic settings and are expensive to...

Accurate Measuring of poverty and its distribution in various areas, in addition to being crucial for cognitive purposes, could have different policy implications and affect policy assessments. The Household expenditures criteria is typically used to measure poverty, and poverty is often assessed using a poverty line and alternative indices. A major difficulty associated with this method is, ho...

We propose graphical methods to determine whether commodity-tax changes are “socially efficient”, in the sense of improving social welfare or decreasing poverty for large classes of social welfare and poverty indices. We also derive estimators of critical poverty lines and economic efficiency ratios which can be used to characterize socially-efficient tax reforms. The statistical properties of ...

Recent empirical literature has seen many multidimensional indices emerge as well-being or poverty measures, in particular indices derived from principal components and various latent variable models. Though such indices are being increasingly and widely employed, few studies motivate their use or report the standard errors or confidence intervals associated with these estimators. This paper re...

The Relationship between Income Inequality, Poverty and Globalisation This paper introduces two composite indices of globalisation. The first is based on the Kearney/Foreign Policy magazine and the second is obtained from principal component analysis. They indicate the level of globalisation and show how globalisation has developed over time for different countries. The indices are composed of ...
