ABSTRACT
The economics of information covers a wide range of topics such as insurance, stochastic equilibria, the theory of finance (e.g. option pricing), job search, etc. In this paper, we focus on an economic model in which traders are uncertain about the true characteristics of commodities and know only the probability distributions of those characteristics. The traders acquire information on those characteristics via the actual consumption in the past and are allowed to exchange the information among themselves prior to the forthcoming trade. Though optimal consumption at the preceding trade generally alters optimal consumption at the succeeding trade, it may happen that they both coincide. We call this particular type of optimal consumption an information stable equilibrium (ISE). At an ISE, the traders gain no additional information from consumption, which is significant enough to revise their optimal choice at the succeeding trade.

    This article presents a note on consumer search and market equilibria. The nature of equilibrium, in a market where consumers search for the lowest price depends sensitively upon the distribution of search costs across consumers.

We show that for such games the (subgame perfect) equilibrium behavior leads to a payoff distribution which approaches the Shapley value as the money...

    Abstract. The stationary distribution of a birth and death process may not be approximated by a diffusion. The general situation is illustrated on the "musical chairs" model by Binmore et al. (1995). This model is shown to generate outcomes which are not captured by the concept of the ultralong...

Thus it is not surprising that when considering Rawls' contribution to justice theory the economists' interest has focused upon Rawls'...
