We study a problem where a group of voters must decide which candidates are elected from a set of alternatives. The voters’ preferences on the combinations of elected candidates are represented by orderings. We propose a family of restrictions of the domain of separable preferences. These...

We study a problem in which a group of voters must decide which candidates are elected from a set of alternatives. The voters’ preferences on the combinations of elected candidates are represented by linear orderings. We propose a family of restrictions of the domain of separable preferences....

This paper analyzes the problem of designing mechanisms to implement efficient solutions in economies with externalities. We provide two simple mechanisms implementing the Pigouvian Social Choice Correspondence in environments in which coalitions can be formed. Finally, we study economies in...

We consider the problem of fair allocate an infinitely divisible commodity among agents with single-•peaked preferences and private endowments. First, we show that the adaptation of the uniform rule to this context is the only selection from the no-envy in redistributions and Pareto efficient...

Controlled branching processes (CBP) with a random control function provide a useful way to model generation sizes in population dynamics studies, where control on the growth of the population size is necessary at each generation. An important special case of this process is the well known...

This study examines the role of fatigue as a possible moderating factor of the relationship between personality and the affective dimensions of well-being: positive affect (PA) and negative affect (NA), as well as affect balance. At the end of their work shift, 218 nursing professionals filled...
