El próximo viernes 11 de noviembre a las 13:00 horas en el Salón de 
Posgrados del INCO habrá una exposición del Prof. Gustavo Bergantiños 
(Research Group in Economic Analysis of the University of Vigo); 
ponencia titulada:

“Strategy-proofness in the division problem with voluntary participation”.

The division problem consists of allocating a given amount of an 
homogeneous and perfectly divisible good among a group of agents with 
single-peaked preferences on the set of their potential shares. A rule 
proposes a vector of shares for each division problem. The literature 
has implicitly assumed that agents will find acceptable any share they 
are assigned to. In this paper we consider the division problem when 
agents' participation is voluntary. Each agent has an idiosyncratic 
interval of acceptable shares where his preferences are single-peaked. A 
rule has to propose to each agent either to not participate or an 
acceptable share because otherwise he would opt out and this would 
require to reassign some of the remaining agents' shares. We present an 
extension of the uniform rule that deal explicitly with agents' 
voluntary participation. Besides we characterize it using a weak version 
of strategy-proofness together with other properties as efficiency, 
equal treatment of equals, bound monotonicity and admissible contraction.
