This paper reviews recent research on the aggregation of heterogeneous time preferences. Main results are illustrated in simple Ramsey models with two or three agents who differ in their discount factors. We employ an intertemporal view on these models and argue that preferences of a decision...

In the standard arrovian framework and under the assumption that individual preferences and social outcomes are linear orders on the set of alternatives, we study the rules which satisfy suitable symmetries and obey the majority principle. In particular, supposing that individuals and...

The paper tries to clarify the status of the market in Social Choice and Individual Values. It shows how Arrow at first intended to propose a third theorem of welfare economics (Feldman [1991]), which would show that the market achieves not only Pareto-optimality, but also equitable social...

The set of alternatives is infinite. If social welfare function f satisfies the Pareto criterion and there is a positive number β such that each pair of alternatives can be socially ordered without having to consult individual preference over a set with more than β alternatives then there are...

The measurement of individual happiness challenges the notion that revealed preferences only reliably and empirically reflect individual utility. Reported subjective well-being is a broader concept than traditional decision utility; it also includes concepts like experience and procedural...

It is well known that many social decision procedures are manipulable through strategic behaviour. Typically, the decision procedures considered in the literature are social choice correspondences. In this paper we investigate the problem of constructing a social welfare function that is...

Child labor is often condemned as a form of exploitation. I explore how the notion of exploitation, as used in everyday language, can be made precise in economic models of child labor. Exploitation is defined relative to a specific social welfare function. I first show that under the standard...

The paper contributes to the use of social choice and welfare theory in health economics by developing and applying the integration of claims framework to health-care rationing. Related to Sens critique of neo-classical welfare economics, the integration of claims framework recognises three...

The recognition that environmental hazards can affect children differently and more severely than adults has provoked growing concern in industrialized nations about the impact of environmental pollution on children’s health. In this paper, commissioned by the OECD, we are charged with...
