Remarks on solidarity in bankruptcy problems when agents merge or split

In this note, we investigate the relationship between non-manipulability via merging (splitting) and strong non-manipulability via merging (splitting). Our analysis reveals that while these two non-manipulability axioms are generally not equivalent, they do coincide when the principle of solidarity...

Description
Summary:In this note, we investigate the relationship between non-manipulability via merging (splitting) and strong non-manipulability via merging (splitting). Our analysis reveals that while these two non-manipulability axioms are generally not equivalent, they do coincide when the principle of solidarity is satisfied. This principle is fulfilled by a wide range of bankruptcy rules, including parametric rules. •We revisit non-manipulability for bankruptcy problems.•We compare non-manipulability and strong non-manipulability via merging and splitting.•We show that, under solidarity, both forms of non-manipulability are equivalent.
