This article addresses conceptual shortcomings in recent literature on coalitional TU-games. We revisit and partly redefine key notions such as coalition, coalition function, efficiency, and duality, emphasizing their dependence on the class of TU-games under scrutiny. Unlike approaches that...

The well-known cooperative game solution core, with its strict stability requirement, provides no solution for non-balanced games. Subiza et al. (2025) relaxes the stability concept of the core and proposes δ-stable set, a non-empty solution for every essential TU-game. However, their approach...

In two-sided markets with money, core stability and marginalism are often in conflict. We reconcile them with two main results. First, we show that in the assignment game (Shapley & Shubik, 1972), the Banzhaf value is core stable if and only if the game is exact. This is surprising for two...

This briefing summarises the evaluation of hundreds of data deliveries received from reporting countries for 13 Eionet core data flows. It shows progress against agreed reporting criteria, allowing countries to identify and prioritise the resources they need for regular reporting procedures.

We propose a one-shot, non-cooperative mechanism that implements the core in a large class of public goods games. Players simultaneously choose conditional commitment functions, which are binding unilateral commitments that condition a player’s contribution on the contributions of others. We...

Globally, sustainable development goals (SDGs), which need to be achieved using the sharing economy, are the focus of many recent studies. This article investigates the impact of sharing economy features such as core competence and resources on achieving SDGs in the tourism industry in the BRICS...

When selling goods like wireless spectrum or electricity contracts, auction designers often opt for core-selecting mechanisms -- i.e., auctions that induce outcomes in the core -- in order to balance revenue and efficiency goals. But increasingly, auctions -- such as the FCC's 2016-17 Incentive...

We study the allocation of indivisible objects under the general endowment structures proposed by Pápai (2000) – the consistent inheritance structures – which specify the initial endowment of objects and also the inheritance of remaining objects after subsets of agents are matched and...
