Abstract

(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 de datos inexactos sobre el ingreso. También realizamos un análisis de sensibilidad al uso de diversas líneas e índices de pobreza, que son cuestiones que han sido analizadas mucho más a fondo en la obra publicada. El análisis de sensibilidad se aplica a datos de encuestas de hogares de 17 países latinoamericanos, los cuales abarcan 92% de la población de la región. Al hacer variar esos parámetros dentro de límites razonables, hallamos que cabe decir que la proporción de pobres es de 12,7% o 65,8% de la población total. Además, la clasificación de países con respecto a la pobreza también es altamente sensible. Esto apunta a la necesidad de justificar y tratar con claridad las opciones y definiciones subyacentes de las estadísticas sobre la pobreza, así como la necesidad de realizar un análisis de sensibilidad que ilustre el menú de opciones que pueden responder a la pregunta de cuánta pobreza hay.
