    Merging-splitting-proofness in financial systems: A characterization result 

    Calleja Cortés, Pedro; Llerena Garrés, Francesc (Publication date: 2026-03-09)

    In this paper, we explore the issue of manipulability in the setting of financial systems by considering two weak forms of immunity: merging-proofness and splitting-proofness. Not surprisingly, splitting-proofness conflicts ...

    This paper studies committee design when a homogeneous population is uncertain about which alternative is correct, individuals can acquire costly information about the state of the world, and the decision must be taken via ...

    Claims manipulations discriminate between egalitarian rules

    We provide axiomatic characterizations of the constrained equal awards and constrainedequal losses rules by imposing immunity principles such as non-manipulability via merging(splitting) and strong non-manipulability via ...

    Egalitarian-in-deviation rules relative to a reference system for resolving conflicting claim problems 

    Izquierdo Aznar, Josep Maria; Rafels, Carles (Publication date: 2026-01-20)

    We study claims problems in which agents may also have reference points. We show first that many classical rules satisfy an egalitarian property in this setting; namely, the differences between each agents’ payoff and the ...

    Local sensitivity analysis of heating degree day and cooling degree day temperature derivative prices 

    Solanilla Blanco, Sara Ana (Publication date: 2025-11-28)

    We study the local sensitivity of heating degree day (HDD) and cooling degree day (CDD) temper-ature futures and option prices with respect to perturbations in the deseasonalized temperature or inone of its derivatives up ...

    Transforming Eurostat’s Table 29 into an Actuarial Balance Sheet: A Net Worth Approach to Assessing Public Pension Solvency

    This article presents a transparent and replicable framework to assess the net worth of public pension systems within the broader context of fiscal sustainability and public sector balance sheets. Using Spain as a case ...

    Matching markets with farsighted couples 

    Atay, Ata; Funck, Sylvain; Mauleon, Ana; Vannetelbosch, Vincent (Publication date: 2025-09-02)

    We adopt the notion of the farsighted stable set to determine which matchings are stable when agents are farsighted in matching markets with couples. We show that a singleton matching is a farsighted stable set if and only ...

    A defined benefit pension plan model with stochastic salary and heterogeneous discounting 

    Josa-Fombellida, Ricardo; López-Casado, Paula; Navas, Jorge (Publication date: 2024-01-10)

    We study the time-consistent investment and contribution policies in a defined benefit stochastic pension fund where the manager discounts the instantaneous utility over a finite planning horizon and the final function at ...

    Cooperative games with size-truncated information 

    Martínez de Albéniz, F. Javier (Publication date: 2015-12-18)

    We study the marginal worth vectors and their convex hull, the so-called Weber set, from the original coalitional game and the transformed one, which is called the Weber set of level k. We prove that the core of the original ...
