This paper considers and assesses the concept of social externalities through humaninterdependence, in relation to the economic analysis of externalities in the tradition of Pigou andArrow, including the analysis of the commons. It argues that there are limits to economic analysis. Our proposal...

We propose the concept of a universal social ordering, defined on the set of pairs of an allocation and a preference profile of any finite population. It is meant to unify evaluations and comparisons of social states with populations of possibly different sizes with various characteristics. The...

An early death is, undoubtedly, a serious disadvantage. However, the compensation of short-lived individuals has remained so far largely unexplored, probably because it appears infeasible. Indeed, short-lived agents can hardly be identified ex ante, and cannot be compensated ex post. We argue...

Behavioral economics has shaken the view that individuals have well-defined, consistent and stable preferences. This raises a challenge for welfare economics, which takes as a key postulate that individual preferences should be respected. This paper scrutinizes the challenge and argues, in...

This paper re-examines the welfare economics of risk. It singles out a class of criteria, the “expected equally-distributed equivalent”, as the unique class which avoids serious drawbacks of existing approaches. Such criteria behave like ex-post criteria when the final statistical...

This paper studies the ethical underpinnings of two social criteria which are prominent in the literature dealing with the problem of evaluating allocations of several consumption goods in a population with heterogeneous preferences. The Pazner-Schmeidler criterion (Pazner-Schmeidler [22]) and...

In this paper we propose different criteria to rank income distributions according to equality of opportunity. Different from existing ones, our criteria explicitly recognize the interplay between circumstances and effort. We characterize them axiomatically and we compare them with existing...

Common sense supports prevention policies aimed at improving survival prospects among the population. It is also widely acknowledged that an early death is a serious disadvantage, and that attention should be paid to the compensation of short-lived individuals. This paper re-examines the...

Behavioral economics has shaken the view that individuals have well-defined, consistent and stable preferences. This raises a challenge for welfare economics, which takes as a key postulate that individual preferences should be respected. We argue, in agreement with Bernheim (2009) and Bernheim...
