  1. Matthias Hild, Mathias Risse, John Harsanyi, John Rawls & John A. Weymark, Preference Aggregation After Harsanyi.
    Consider a group of people whose preferences satisfy the axioms of one of the current versions of utility theory, such as von Neumann-Morgenstern (1944), Savage (1954), or Bolker-Jeffrey (1965). There are political and economic contexts in which it is of interest to find ways of aggregating these individual preferences into a group preference ranking. The question then arises of whether methods of aggregation exist in which the group’s preferences also satisfy the axioms of the chosen utility theory, and in which (...)

    This article illustrates how axiomatic social choice theory can be used in the evaluation of measures of group fitness for a biological hierarchy, thereby contributing to the dialogue between the philosophy of biology and social choice theory. It provides an axiomatic characterization of the ordering underlying the MichodSolariNedelcu index of group fitness for a multicellular organism. The MVSHN index has been used to analyse the germ-soma specialization and the fitness decoupling between the cell and organism levels that takes place during (...)

  5. Marc Fleurbaey, Maurice Salles & John A. Weymark (eds.) (2008). Justice, Political Liberalism, and Utilitarianism: Themes From Harsanyi and Rawls. Cambridge University Press.
    The utlitiarian economist and Nobel Laureate John Harsanyi and the liberal egalitarian philosopher John Rawls were two of the most eminent scholars writing on problems of social justice in the last century. The contributions to this volume, addressed to an interdisciplinary audience, pay tribute to them by investigating themes that figure prominently in their work. In some cases, the contributors explore issues considered by Harsanyi and Rawls in more depth and from novel perspectives. In others, the contributors use the work (...)

  7. John A. Weymark, Aanund Hylland & Allan F. Gibbard, Arrow's Theorem with a Fixed Feasible Alternative.
    Arrow's Theorem, in its social choice function formulation, assumes that all nonempty finite subsets of the universal set of alternatives is potentially a feasible set. We demonstrate that the axioms in Arrow's Theorem, with weak Pareto strengthened to strong Pareto, are consistent if it is assumed that there is a prespecified alternative which is in every feasible set. We further show that if the collection of feasible sets consists of all subsets of alternatives containing a prespecified list of alternatives and (...)

  8. Arja H. Turunen-Red & John A. Weymark (1999). Linear Aggregation of SSB Utility Functionals. Theory and Decision 46 (3):281-294.
    A necessary and sufficient condition for linear aggregation of SSB utility functionals is presented. Harsanyi's social aggregation theorem for von Neumann–Morgenstern utility functions is shown to be a corollary to this result. Two generalizations of Fishburn and Gehrlein's conditional linear aggregation theorem for SSB utility functionals are also established.
