This paper develops a model of evolution of beliefs through communication in an exogenous social network. We assume that the agents are Bayesian updaters and that the network enables them to listen to the opinion of others about some uncertain parameter of interest. We explore the effects of the...

We consider two specific network structures, the star and the line, and study the set of bilateral alternating-offers bargaining procedures for the pairs of connected agents. Agents have complementary information and bargain over the relative price of their pieces of information. We characterize...

This paper studies the evolution of beliefs of a group of Bayesian updaters who are connected through a social network that enables them to listen to the opinions of others. Each agent observes a sequence of private signals about the value of an unknown parameter. In addition, the agent receives...

This paper develops a model of costly information acquisition by agents who are connected through a network. For a exogenously given network, each agent decides first on information acquisition from his neighbors and then, after processing the information acquired, takes an action. Each agent is...

We consider a class of two-player quadratic games under incomplete information to study the relation between exogenous coordination motives and strategic interactions in information acquisition. The players make decisions in two stages. They decide about information acquisition in the first...

J. D. Geanakoplos and H. M. Polemarchakis (1986) prove the generic constrained suboptimality of equilibrium allocations in two period economies with incomplete markets. In these notes we provide a complete and detailed version of their proof with alternative arguments when needed.

This paper considers two-player quadratic games to examine the relation between strategic interactions in actions and in information decisions. We analyze the role of external effects and of the relative intensities with which the players’ actions interact with the uncertain payoff-relevant...

We introduce a dominance intensity measuring method to derive a ranking of alternatives to deal with incomplete information in multi-criteria decision-making problems on the basis of multi-attribute utility theory (MAUT) and fuzzy sets theory. We consider the situation where there is imprecision...

The lack of statistical interdependence relationships between pH and conductivity in channels exposed to Acid Mine Drainage processes is a phenomenon reported by various authors. Based on the study of a large mass of data with over 23,000 records of pH and conductivity taken in a typical mining...

We consider pure exchange, one good OLG economies under stationary Markov uncertainty. It is known that when markets are sequentially complete, a stationary equilibrium at which the agents common matrix of intertemporal rates of substitution has a Perron root which is less than or equal to one...
