Multiple economic experiments suggest that the moral context of consumption and/or production influences willingness-to-pay and willingness-to-accept. Precisely how this influence should be modeled from a theoretical perspective, however, remains understudied. The prevailing view is that moral...

The paper proposes an alternative index of relative deprivation which allows for selection of the reference group and imperfect information, two central elements of modern theories of social justice. An application to real data and a simulation on artificial data illustrate the use and some...

In this article we provide an overview of the Gini decomposition and the generalized entropy inequality measures, a free access to their computation, an application on French wages, and a different way than Dagum to demonstrate that the Gini index is a more convenient measure than those issued...

This note shows that results similar to Arrow's Impossibility Theorem can be proved by replacing the weak Pareto principle by a weaker condition called Pareto Neutrality and used by Xu (1990) to state another version of Sen''s liberal paradox. Our result strengthens Xu''s arguments for taking...

Consumer's surplus can be seen as a correct measure of the change in welfare under special conditions on the preferences of the consumer. The note addresses the question whether the intuitive appeal of the consumer''s surplus concept in the one-price change case extends into cases where several...

The paper perceives education as a type of money burning activity, much like advertisement, and examines its effect on social welfare. In a model where the employer's job assignment also functions as a signal a la Waldman (1984), there exists a separating equilibrium in which education credibly...

This paper lends legitimacy to the food share as an indicator of welfare by demonstrating the conditions necessary in empirical work for the Engel method of estimating equivalence scales to provide an exact measure of welfare. In analogy to a money metric of utility, the Engel's food share is...

Using unique data from a large-scale online survey conducted in Germany, we examine gender differences in volunteering for charitable organisations. Our findings suggest that men are more likely than women to engage in regular volunteer activities. Additionally, we find that men devote more time...

The present note is an elementary essay on how one may manipulate the Lorenz curve with a view to obtaining a couple of simple variants of the Gini coefficient of inequality, one of which is anti transfer-sensitive and the other pro transfer-sensitive, and which together, in convex combination,...

This paper examines the impact of immigration on income inequality. Using data from 1990 and 2000 US Censuses, we link the changes in income inequality as measured by the Gini index with immigrant flows into each metropolitan area in the U.S. We address endogeneity of immigrant inflows by...
