For decades, experimental economics has been very interested in behavior that could be characterized as practicing solidarity (although the term is rarely used). Solidarity is a key concept in Catholic Social Teaching. This paper builds a bridge between these two endeavors that, thus far, had...

In their recent seminal work, Kaplow and Shavell demonstrate that any metric for policy evaluation that takes into account factors other than individual welfare is Pareto-inefficient; in particular, they argue at length that notions of fairness - insofar as they do not directly contribute to...

This paper aims to study the impact of positional concerns on social preferences and social capital. We utilize data from the “Caucasus Barometer” survey administered in three post-Soviet transition economies: Armenia, Azerbaijan, and Georgia. Controlling for absolute income and other...

A transfer from a richer individual to a poorer one seems to be the most intuitive and straightforward way of reducing income inequality in a society. However, can such a transfer reduce the welfare of the society? We show that a rich-to-poor transfer can induce a response in the individuals'...

In determining the optimal redistribution of a given population's income, we ask which factor is more important: the social planner's aversion to inequality, embedded in an isoelastic social welfare function indexed by a parameter alpha, or the individuals' concern at having a low relative...

Inequity plays a fundamental role in the evaluation of social welfare in many dimensions.We revisit the concept of inequity, whether across states of world (uncertainty), across individuals (inequality) and across generations (intergenerational equity), using a common framework generalizing the...

Multidimensional welfare analysis has recently been revived by money-metric measures based on explicit fairness principles and the respect of individual preferences. To operationalize this approach, preference heterogeneity can be inferred from the observation of individual choices (revealed...

Amartya Sen has shown how liberal rights can produce outcomes that everyone would prefer to avoid, thereby violating the Pareto principle. Similarly, Louis Kaplow and Steven Shavell identify potential conflicts between the Pareto principle and notions of "fairness," which give weight to...
