Summary

Descripción general del contenido del recurso.

Esta nota utiliza técnicas computacionales como el bootstrap para obtener estimaciones por intervalos y errores estándar para las medidas de desigualdad. Adicionalmente, esta metodología es utilizada para implementar un test formal de la hipótesis nula de ausencia de cambios en la desigualdad entre dos períodos. Los resultados se aplican al caso de Argentina, en donde la desigualdad varió sustancialmente en la última década, por lo que resulta crucial distinguir la variabilidad muestral de los verdaderos cambios en la distribución del ingreso. Los resultados muestran que este problema no es menor, dado que para varias regiones de Argentina los cambios observados en el coeficiente de Gini no son estadísticamente significativos. This note illustrates how modern computer intensive tools like the bootstrap provide a simple and efficient way to compute interval estimates and standard errors for inequality measures. Additionally, the same methodology is used to implement a formal test of the null hypothesis of no changes in income inequality between two periods. Results are applied to the case of Argentina, where inequality varied substantially in the last decade, making crucial the issue of distinguishing sampling variability from true changes in the distribution of income. Our results show that the problem is not minor, since the observed changes un the Gini coefficients for several regions in Argentina are not statistically significant.
