A new method for building parametric-functional families of Lorenz curves, generated from an initial Lorenz curve (which satisfies some regularity conditions), is presented. The method is applied to the exponential family since they use the exponential Lorenz curves as their generating curves....

Using ARIMA models and entropy, the dynamic evolution of several functions of aggregate income and other attributes of well-being is analysed for statistical 'similarity' in order to determine potentially distinct dimensions in multidimensional analysis of welfare and quality of life in the USA....

This paper focuses on the problem of analyzing how factors impact hunger across states when hunger is ill-defined. Hunger (which is a latent variable) is presumed to depend on macroeconomic, legislation, policy, and demographic variables. Based on the Bayesian method of a posterior odds ratios,...
