A solution on a set of transferable utility (TU) games satisfies strong aggregate monotonicity (SAM) if every player can improve when the grand coalition becomes richer. It satisfies equal surplus division (ESD) if the solution allows the players to improve equally. We show that the set of...

We investigate manipulability in the setting of financial systems by considering two weak forms of immunity: non-manipulability via merging and nonmanipulability via splitting. Not surprisingly, non-manipulability via splitting is incompatible with some basic axioms: claim boundedness, limited...

We explore the relationship between non-manipulability via merging (splitting) and strong non-manipulability via merging (splitting). We show that although, in general, these non-manipulability properties are not equivalent, under the principle of solidarity, fulfilled by a wide range of...

We address the problem of clearing mutual obligations among agents when a financial network collapses. To do so, we adopt an axiomatic approach and provide the first comprehensive characterization of the rules based on the principle of proportionality, covering the entire domain of financial...

When a financial network collapses, how should mutual obligations among all agents be cleared? We study this problem taking an axiomatic approach and provide the first characterization of the family of rules based on the principle of proportionality in the entire domain of financial systems. A...
