This paper studies coalition formation among individuals who differ in productivity. The output of a coalition is determined by the sum of productivities if the coalition exceeds a minimal threshold of members. We consider competitive societies in which the surplus of a coalition is split...

We experimentally study how redistribution choices are affected by positive and negative information regarding the behaviour of a previous participant in a dictator game with a taking option. We use the strategy method to identify behavioural ‘types', and thus distinguish ‘conformists' from...

Corruption is now one of the major challenges in many countries around the world, mainly because of its adverse impact on social and economic development. In today's world people are more likely to opt for what is easier and simple even if it is not honest and acceptable. In this paper, we use...

Italian Abstract: Vengono esposti i tradizionali modelli di oligopolio con bene omogeneo a mosse simultanee, sequenziali e colllusive, con variabile strategica quantità o prezzo. L'utilizzo di funzioni lineari permette di calcolare e comparare tutte le soluzioni

In this paper we review a number of coalitional solution concepts for the analysis of the stability of cartels and mergers under oligopoly. We show that, although so far the industrial organization and the cooperative game-theoretic literature have proceeded somehow independently on this topic,...

In this paper the extended model of Minority game (MG), incorporating variable number of agents and therefore called Grand Canonical, is used for prediction. We proved that the best MG-based predictor is constituted by a tremendously degenerated system, when only one agent is involved. The...

Generalization of the minority game to more than one market is considered. At each time step every agent chooses one of its strategies and acts on the market related to this strategy. If the payoff function allows for strong fluctuation of utility then market occupancies become inhomogeneous...

We study minority games in efficient regime. By incorporating the utility function and aggregating agents with similar strategies we develop an effective mesoscale notion of state of the game. Using this approach, the game can be represented as a Markov process with substantially reduced number...

The business of the law is to influence human behavior. To do this effectively, lawmakers must make assumptions about human psychology and how people think. While the behavioral sciences dedicate their entire enterprises to investigating these questions, the law, even at its best, incorporates...

We introduce a new solution concept for models of coalition formation, called the myopic stable set (MSS). The MSS is defined for a general class of social environments and allows for an infinite state space. An MSS exists and, under minor continuity assumptions, it is also unique.The MSS...
