The axioms of expected utility and discounted theory have been tested extensively. In contrast, the social welfare functions only in a few questionnaire studies involving choices between hypothetical income distributions. controlled experiment with 100 subjects placed role planners, we test five fundamental properties to determine efficacy traditional choice models predicting planner allocation...

Income from off-farm sources is especially important for land-poor households. However, the pattern of participation in off-farm activities is heterogeneous across space. We explore the determinants of participation in off-farm non-agricultural employment using data for rural Mexico. In particular, we try to understand how the neighborhood and the neighbors’ characteristics and choices affect t...

There is mixed evidence as to whether concrete manipulatives (e.g., toy animals) are better than abstract counters) for teaching mathematical concepts children. Concreteness defined the amount of extraneous information a manipulative provides, and in this study we aimed unpick which dimensions concreteness influence choice. Researchers, teachers, parents completed comparative judgment task comp...

Game theory has been variously described as the science of strategy or that of conflict resolution. At its core, it has the characteristics of a mathematical construct: a clear set of concepts and assumptions, fundamental theorems, and applications to real world issues. The fact that the issues in question are mostly the domains of the social sciences, however, places game theory in a peculiar ...

Social choice theory is a field that concerns methods of aggregating individual interests to determine net social preferences. Arrow’s Impossibility Theorem states that no social choice system can satisfy all requirements in a collection of “reasonable” criteria. We make the notion of “reasonable” voting systems precise by stating the four properties that voting systems must have in order to be...

They include Weymark. None of them is responsible for the …nal shape and contents of this piece, as I could only very partially take their comments into account. I received very valuable assistance from Conx...
