This paper tests the sensitivity of poverty indexes to the choice of adult equivalence scales, assumptions about the existence of economies of scale in consumption, methods for treating missing and zero incomes, and different adjustments to handle income misreporting. The sensitivity analysis is applied to household survey data from 17 Latin Americ...

(Disponible en idioma inglés únicamente) En este trabajo se pone a prueba la sensibilidad de los índices de pobreza a la selección de escalas de equivalencia de adultos, suposiciones sobre la existencia de economías de escala en el consumo, métodos para tratar la pérdida de ingreso o ingresos nulos, y diversos ajustes para manejar las declaraciones...

By applying a recently developed methodology that allows combining data from the 2001 Population and Housing Census and the 2002 Survey of Living Conditions, it is possible to generate welfare estimates at the special area level, a breakdown...

... The presence of non-positive incomes is quite common in household surveys; negative incomes can be a significant portion of total incomes, and zero incomes can also be highly prevalent in number. According to Ravallion (2017), about 400 of the 700 income surveys included in the World Bank's PovcalNet data repository have non-positive values and, according to Verma and Betti (2010), 3% of total Disposable Household Incomes (DHI) among European Union Surveys on Income and Living Conditions (EU-SILC) data are negative or zero (see also Van Kerm, 2007;Hlanky et al., 2021;Székely et al., 2007). In 12 of the Luxembourg Income Study (LIS) surveys analyzed by Hlasny et al. (2021), negative incomes accounted for over one percent of nonzero incomes, numbered up to 584 observations in a national survey, and could be as large in absolute value as 754% of mean nationwide positive income. ...

... Equivalence scales are used to make the incomes of households of different sizes and compositions comparable. They provide the basis for calculating inequality and poverty measures (e.g., Buhmann et al. 1988;Szelky et al. 2004). It has, however, been pointed out that these measures are sensitive to the specific equivalence scale used, and there has so far been no consensus on which equivalence scale should be applied (e.g., Lewbel 1989b;Blundell and Lewbel 1991). ...
