For some, the income distribution is the first example of a power law, empiric rule whereof an random variable reaches high values with a low probability and low values with a high probability. This article corroborates if the income distribution of the richest Colombians adjusts to a power law....

We study Kolmogorov-Smirnov goodness of fit tests for evaluating distributional hypotheses where unknown parameters need to be fitted. Following work of Pollard (1979), our approach uses a Cramér-von Mises minimum distance estimator for parameter estimation. The asymptotic null distribution of...

We consider a weighting scheme that yields a best-case scenario for measured human development such as the official equally-weighted Human Development Index (HDI) using an approach that relies on consistent tests for stochastic dominance efficiency (SDE). We compare the official equally-weighted...

We consider a weighting scheme that yields the best-case scenario measurement of the Human Development Index (HDI) using an approach that relies on consistent tests for stochastic dominance efficiency (SDE). We compare a given hybrid composite index such as the official equally-weighted HDI to...

This paper addresses the specification of the econometric models used in the paper “Level of Development, Rate of Economic Growth, and Income Inequality†by Jih Y. Chang and Rati Ram (2000). We find that when accounting for regional heterogeneity, the Kuznets hypothesis no longer...

Se establece un modelo estocástico que describe un esquema piramidal tipo Ponzi. Se estudia su comportamiento, su punto crítico (definido en términos del estado financiero de la captadora), su punto de saturación (definido en términos del capital real de la captadora) y se define un índice...

Mediante simulación, se estudian varios casos de fraude provocados por pirámides financieras tipo Ponzi (incluyendo los casos Madoff, DRFE y Cabrera); la técnica empleada corresponde a la implementación computacional de un modelo estocástico diseñado por J. Mayorga-Zambrano. Se comparan...

Aun cuando las diferentes medidas convencionales del Producto Bruto Interno (PBI) muestran el desempeño económico del país, el cálculo de éstas no considera el significativo valor de los bienes y servicios producidos dentro del hogar. A través de la Encuesta Nacional del Uso de Tiempo...

This paper evaluates the impact of the economic downturn on Spanish wage polarization. Using the index of polarization of Palacios-González and García-Fernández (2012), we have computed polarization structuring the earners population into groups according to their wages, gender, education,...
