Old welfare economics, Pigou (1920), considered social welfare as a cardinal notion, while new welfare economics,1 Little (1950) and Graaff (1957), consider social welfare as an ordinal notion. An in depth introduction to welfare economics and a discussion of the transition from old to new welfare economics, is expounded quite well by Samuelson (1947, Chap. 8, pp. 203–219, and pp. 249–252). For...

Electric universal service aims to improve the individual living quality in remote and underdeveloped areas, the implementation of which can promote the sustainable development of people’s lives and the local economy to some extent. A social welfare evaluation model of electric universal service was proposed, which was divided into economic and non-economic welfare evaluation models. After the ...

We present some results on social welfare function and social choice function. First, we replace weak Pareto principle of Arrow’s axioms with strong Pareto principle, and then show that assuming unrestricted domain property, independence of irrelevant alternatives and strong Pareto principle on a social welfare function in Arrow’s sense leads to the existence of first to nth commanders whose st...

T he optimal allocation of natural gas resources to various uses such as final and intermediate consumption, injection into oil fields, and exports can help policymakers to use this kind of resources efficiently. Empirical evidence support using hyperbolic discount rates instead of fixed discount rates in the economic literature. The purpose of this study is to maximize the social we...

We characterize the class of Arrovian Social Welfare Functions as integer solutions to a collection of linear inequalities. Many of the known results about impossibility, Arrovian Social Welfare Functions, properties of the majority rule etc., can be derived in a simple and unified way from this integer program. We characterize those preference domains that admit a non-dictatorial, neutral Arro...

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 dynastic social welfare function, which is commonly applied to intergenerational models, child labor is...

This paper studies the nature of social welfare orders on infinite utility streams, satisfying the efficiency principle known asMonotonicity and the consequentialist equity principle known as Strong Equity. It provides a complete characterization of domain sets for which there exists such a social welfare order which is in addition representable by a real valued function. It then shows that for...
