In this paper, we study the immunity of bankruptcy rules to manipulation via merging or splitting agents' claims. We focus on the TAL-family of bankruptcy rules (Moreno-Ternero amp; Villar, 2006), a one-parameter family encompassing three classical rules: the Talmud (T) rule, the constrained...

We explore the relationship between proportionality and manipulation (via merging or splitting agents' claims) in bankruptcy problems. We provide an alternative proof to the well-known result that, in an unrestricted domain, immunity to manipulation is equivalent to requiring proportional...

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...

The top-two primary is the new primary system passed in several states of the US that creates a single ballot in which the top two vote getters pass to the general election. Primary elections induce a sequential game with three stages: the candidate-entry stage, the primary election stage, and...

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...

The top-two primary recently approved in states like Washington, California, and Alaska eliminates the closed party primaries and creates instead a single ballot in which the first and second place winners pass to the general election. We compare the electoral consequences of the top-two primary...

Agents are connected each other through a tree. Each link of the tree has an associated cost and the total cost of the tree must be divided among the agents. In this paper we assume that agents are asymmetric (think on countries that use aqueducts to bring water from the rainy regions to the dry...
