I review the complex welfare economic issues that arise in environmental decision-making over very long periods, as in cases relating to climate change and biodiversity loss. I also consider the issues that arise in choosing a discount rate to apply to very long-run projects and indicate how...

As suggested by its title, this paper looks at the subject of economic welfare from the perspectives of Islam. It starts with the definition of economic welfare, and clarifies how this subject is different from “welfare economics.” It further explains that economic welfare means how well...

Amartya Sen’s impossibility of a Paretian liberal underscores the trade-off between two widely applied social principles—liberalism and Pareto-optimality: “If someone does have certain liberal values, then he [or she] may have to eschew his [or her] adherence to Pareto optimality” (Sen...

This chapter examines the role of altruistic motives in the economic analysis of public social transfers, both from a positive and from a normative point of view. The positive question is to know whether we can fully neglect altruistic considerations to explain the development or sustainability...

Assessments of social welfare do not usually take into account population sizes. This can lead to serious social evaluation flaws, particularly in contexts in which policies can affect demographic growth. We develop in this paper a little-known though ethically attractive approach to correcting...

When individuals’ utility is a convex combination of their income and their concern at having a low relative income (the weights attached to income and to the concern at having a low relative income sum up to one), the maximization of aggregate utility yields an equal income distribution. This...

When individuals' utility is a convex combination of their income and their concern at having a low relative income (the weights attached to income and to the concern at having a low relative income sum up to one), the maximization of aggregate utility yields an equal income distribution. This...

In this paper we develop theoretical criteria and econometric methods to rank policy interventions in terms of welfare when individuals are loss-averse. The new criterion for "loss aversion-sensitive dominance" defines a weak partial ordering of the distributions of policy-induced gains and...

The use of equivalence scales for the measurement of inequality and social welfare poses a difficult ethical and technical dilemma. If all individuals are weighted equally while individual welfare measures are based on income or consumption per equivalent adult, then standard properties assumed...

Some claim that `incommensurability` poses serious problems for the standard account of rationality and for the case for markets in economics. Incommensurability may indeed involve violations of basic axioms, such as completeness, transitivity and continuity. Sen`s version of the maximization...
