This paper extends the heterogeneous agent overlapping generations model with bequests in Nishiyama (2000) by adding two-way intergenerational altruism and inter vivos transfers. Calibrating the model to the U.S. economy, the paper measures time preference and intergenerational altruism consistent with the economy¶s capital-output ratio and the sizes of intergenerational transfers. In the model...

Although the Gini coefficient is an ideal measure of income inequality, it may be applied to measure the aging inequality in a society. In this paper, an attempt has been made to develop alternative measures of aging inequality based on the Gini index. The study uses the secondary population data of Asian countries collected from the international data base, US census Bureau. From the analysis ...

Objective: We show that a standardized Gini coefficient that takes into account the feasible range of health inequality for a given health attribute is a better instrument than the normal Gini coefficient for quantifying inter-individual health inequality. Methods: The standardized Gini coefficient is equal to the normal Gini coefficient divided by the maximal attainable Gini coefficient, which...

This note provides an unbiased estimator for the absolute S-Gini and an almost unbiased estimator for the relative S-Gini for integer parameter values. Simulations indicate that these estimators perform considerably better then the usual estimators, especially for small sample sizes. 1 The absolute and relative S-gini indices Assume that income is distributed according to a continuous and diffe...

Classification has been used for predicting medical diagnosis. Classification methods can handle both numerical and categorical attributes. Gini index uses the method which biases multivalued attributes. When the number of classes are large, and the biases are increased, the Gini-based decision tree method is modified to overcome the known problems, by normalizing the Gini indexes by taking int...

Lorenz curve and Gini index are the famous tools of income inequality. When one wants to study income inequality of a class of individuals, Partial Lorenz Curve is introduced and the corresponding measure of inequality called Partial Gini Index is defined. Partial Gini Index (PGI) is derived on Partial Lorenz Curve (PLC). Partial orderings are defined for comparison of partial Lorenz curves. Fo...

81 National Tax Journal Vol. LXI, No. 1 March 2008 Abstract Do income taxes levied at a state or regional level affect the after–tax distribution of income? Or do workers merely move between regions, causing pre–tax wages to adjust? Using the full income tax parameters for all U.S. states from 1977–2002, I create a “simulated tax redistribution index” that captures the mechanical impact of chan...

Income and wealth differ over the life cycle. In cross-sectional distributions of income or wealth, classical inequality measures such as the Gini, could therefore find substantial inequality even if everyone have the same life-time income or wealth. We describe the AG index (Almås and Mogstad, 2011) which is a generalization of the classical Gini index with attractive properties, and we provid...
