Experimental studies have consistently shown that cooperative outcomes can emerge even in finitely repeated games. Such outcomes are justified by existing reputation building models, which suggest that cooperative outcomes can be sustained if some subjects have other-regarding preferences. While...

This paper is a review of the recent advances in the measurement of inequality. Inequality can have several dimensions. Economists are mostly concerned with the income and consumption dimensions of inequality. Several inequality indices including the most widely used index of inequality namely...

Using data from U.S. Major League Baseball, this article compares parametric and nonparametric Gini coefficients for each team and year. We employ a panel-data model to investigate the time-series and cross-sectional factors affecting the Gini coefficients and the parameters of the preselected...

In this paper we investigate the relationship between inequality and the environment in a growing economy from a political economy perspective. We consider an endogenous growth economy, where growth generates pollution and a deterioration of the environment. Public expenditures may either be...

This paper critically assesses widely applied methods of Gini decomposition by income sources and population subgroups. We point to common pitfalls in the interpretation of decomposition results and show that marginal efects provide the only meaningful way to examine the relevance of income...

In this paper we consider some elementary and fair zero-sum games of chance to study the impact of random effects on the wealth distribution of N interacting players. Even if an exhaustive analytical study of such games between many players may be tricky, numerical experiments highlight...

We observe that CEO compensation and top incomes in the US have both been increasing rapidly over the last thirty years. We hypothesize that the trends in CEO compensation have been caused by the same economy-wide factors that have contributed to increases in income. We test this hypothesis by...

For estimating distributions from grouped data, setting up moment conditions in terms of group shares and group means leads to an optimal weight matrix and a GMM objective function that are considerably simpler than those from a previous specification. Minimization is more efficient and...

This letter uses an augmented gravity model to revisit the effect of similarity in income distributions on bilateral trade flows. We document a robust new empirical regularity: while differences in average incomes between two countries increase trade, differences in income dispersion reduce it....

The evil eye belief is a widespread superstition according to which people can cause harm by a mere envious glance at coveted objects or their owners. This paper argues that such belief originated and persisted as a useful heuristic under conditions in which envy was likely to trigger...
