The transition towards a sustainable energy model requires broad
consensus for success. This paper analyses the role of
environmental conscience, (general and specific) knowledge, and
social context on the acceptance of Energy Communities (ECs) in
a sample of individuals living in urban and rural Catalan
municipalities with and without Energy Communities. Regression
estimates show that while having an environmental conscience
has direct and positive, albeit small, effects on the acceptance of
ECs, the effects of social context and specific knowledge of the
ECs are larger and only arise through the urban-rural divide and
differences in individual characteristics (education and labour
status), respectively. In contrast, a general knowledge of climate
agreements and environmental regulations does not change the
acceptance of ECs, neither directly nor mediated by the urbanrural
divide. Public policies supporting energy communities
should prioritize removing legal barriers, target rural areas first,
and tailor communication and education efforts to diverse social
groups. Solving these ones should be a priority and a starting point for
policy makers.

Over the last two centuries, the international financial system has
undergone significant developments, with key historical events shaping
financial markets and economies worldwide. We offer a new long-term
perspective on international financial market integration using a flexible
dynamic panel approach that accommodates heterogeneous slope
coefficients while accounting for cross-country dependence. Our analysis
uncovers several interesting findings. For real long-term interest rates, we
observe a distinct U-shaped pattern. In contrast, the integration of global
financial markets for equities has significantly increased in recent years.
Additionally, long-term nominal interest rates and bond markets have
become considerably more integrated since the Bretton Woods era,
exhibiting a J-shaped pattern throughout the period under study.

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 with basic requirements such as the priority of debt over equity and the limited liability of equity. Remarkably, we provide a comprehensive characterization of the class of bankruptcy rules that gives rise to financial rules that satisfy merging-proofness.

We explore the compatibility of uniform self-consistency and ordinary self-consistency, two extensions for handling multi-valued solutions within the consistency principle introduced by Hart and Mas-Colell (1989), with basic properties, such as reasonableness, which establishes bounds for payoffs based on the marginality principle. Our analysis focuses on convex games and balanced games through the study of almost positive games, a subset of convex games that plays a crucial role in the vector lattice structure of games. Further, we provide new axiomatic foundations of the core incorporating these consistency properties.

"Stable sets are introduced by von Neumann and Morgenstern (1944) as
«the solution» of a cooperative game. Later on, Gillies (1953) defines the
core of the game. Both notions can be established in teStable sets were
introduced by von Neumann and Morgenstern (1944) as "the solution" to
a cooperative game. Later, Gillies (1953) defined the core of the game.
Both concepts can be formulated in terms of dominance. It is well known
that the core may be empty, while stable sets may fail to exist or may
yield multiple proposals. We introduce a new dominance relation such that
the stable set obtained under this notion (the delta-stable set) always
exists, is unique, and coincides with the core of the cooperative game
whenever the core is non-empty. We apply this concept to certain specific
classes of transferable utility games (TU-games) that typically have an
empty core: voting (majority) games, minimum cost spanning tree games
with revenue, controlled capacitated networks, and m-sequencing
games."
