This paper suggests a new approach for centrality measures for general (weighted) networks taking into account the importance for cohesion and relative power of connections. While existing literature either ignores the importance for cohesion or measures it by analyzing consequences arising from...

This paper examines how neutral the current EU decision-making procedures are to membership and how well they obey certain transparent general constitutional principles. The paper evaluates the performance of the procedures by strategic and classical power indices. The main emphasis in the...

We show theoretical and experimental results that demonstrate the potential of transparency to influence committee decision making and deliberation. We present a model in which committee members have career concerns and unanimity is needed to change the status quo. We study three scenarios -...

Which are the new frontiers in central banking? Which things have changed in the aftermath of the financial, economic and sovereign debt crisis? These are questions raised frequently by central bankers, academics and interested observers alike. There are quite a few areas to cover in answering...

Cerreia-Vioglio, Ghirardato, Maccheroni, Marinacci and Siniscalchi (Economic Theory, 48:341-375, 2011) have recently axiomatised preferences in the presence of ambiguity as Monotonic Bernoullian Archimedean (MBA) preferences. We investigate the problem of Arrovian aggregation of MBA preferences...

We analyse river sharing games in which a set of agents located along a river shares the available water. Using coalition theory, we find that the potential benefits of water trade may not be su cient to make all agents in the river cooperate and acknowledge property rights as a prerequisite for...

We study decision rules for committees that repeatedly take a binary decision. Committee members are privately informed about their payoffs and monetary transfers are not feasible. In static environments, the only strategy-proof mechanisms are voting rules which are criticized for being...

Recent empirical evidence shows that the few firms that receive subsidies are large, and that large firms take a prominent role in shaping public policy by lobbying. In this paper, I present a theoretical framework that accounts for these empirical facts in a unified way. I study the role of...
