Social choice theory is a branch of welfare economics that extends the theory of rational choice to collective decision-making. [1] Social choice studies the behavior of different mathematical procedures ( social welfare functions ) used to combine individual preferences into a coherent whole.
Social Choice and Welfare is a quarterly peer-reviewed academic journal covering social choice and welfare economics. The journal was established in 1984 and is published by Springer Science+Business Media. According to the Journal Citation Reports, the journal has a 2013 impact factor of 0.590. [1]
The Introduction contrasts voting and markets with dictatorship and social convention (such as those in a religious code). Both exemplify social decisions. Voting and markets facilitate social choice in a sense, whereas dictatorship and convention limit it. The former amalgamate possibly differing tastes to make a social choice.
Arrow's impossibility theorem is a key result on social welfare functions, showing an important difference between social and consumer choice: whereas it is possible to construct a rational (non-self-contradictory) decision procedure for consumers based only on ordinal preferences, it is impossible to do the same in the social choice setting ...
The ICSW has its origins in 1928 when the International Conference on Social Work, its immediate predecessor, was born in Paris, with the aim of strengthening cooperation between various countries in promoting human welfare. The first Conference had a high proportion of women participating in its preparation and discussions, with nearly two ...
Computational social choice is a field at the intersection of social choice theory, theoretical computer science, and the analysis of multi-agent systems. [1] It consists of the analysis of problems arising from the aggregation of preferences of a group of agents from a computational perspective.
In social choice theory, unrestricted domain, or universality, is a property of social welfare functions in which all preferences of all voters (but no other considerations) are allowed. Intuitively, unrestricted domain is a common requirement for social choice functions, and is a condition for Arrow's impossibility theorem.
His research interests were in social choice theory and welfare economics. [4] He was also a Fellow of the Econometric Society . [ 5 ] He was named a Person of Cultural Merit in 2017.
