The Core Can Be Accessed with a Bounded Number of Blocks
Kóczy, László - 2005
games with non-empty cores this means that the core can be reached via a bounded sequence of blocks. …

Stable Allocations of Risk

portfolio by studying transferable utility cooperative games: risk allocation games. We show that the class of risk allocation … games coincides with the class of totally balanced games. As a limit case the aggregate portfolio can have the same payoff … in all states of nature. We prove that the class of risk allocation games with no aggregate uncertainty coincides with …

Strategic power indices: Quarrelling in coalitions
Kóczy, László Á. - 2008
While they use the language of game theory known measures of a priory voting power are hardly more than statistical expectations assuming voters behave randomly. Focusing on normalised indices we show that rational players would behave differently from the in-dices predictions and propose a...

Prospects after the Voting Reform of the Lisbon Treaty
Kóczy, László Á. - 2010
The European Union used to make decisions by unanimity or near unanimity. After a series of extensions, with 27 member states the present decision making mechanisms have become very slow and assigned power to the members in an arbitrary way. The new decision rules accepted as part of the Lisbon...

The traditional voting games are special transferable utility cooperative games, so-called simple games, where the … or not. In this paper we introduce general weighted voting games, where the value of a coalition is a random variable. We …

Core Concepts for Incomplete Market Economies
Habis, Helga; Herings, P. Jean-Jacques - 2011
We examine the notion of the core when cooperation takes place in a setting with time and uncertainty. We do so in a two-period general equilibrium setting with incomplete markets. Market incompleteness implies that players cannot make all possible binding commitments regarding their actions at...

Transferable Utility Games with Uncertainty
Habis, Helga; Herings, P. Jean-Jacques - 2011
We introduce the concept of a TUU-game, a transferable utility game with uncertainty. In a TUU-game there is uncertainty regarding the payoffs of coalitions. One out of a finite number of states of nature materializes and conditional on the state, the players are involved in a particular...

Analysis of Stochastic Matching Markets
Biró, Péter; Norman, Gethin - 2011
Suppose that the agents of a matching market contact each other randomly and form new pairs if is in their interest. Does such a process always converge to a stable matching if one exists? If so, how quickly? Are some stable matchings more likely to be obtained by this process than others? In...
