We study environments where a production process is jointly shared by a finite group of agents. The social decision involves the determination of input contribution and output distribution. We define a competitive solution when there is decreasing returns-to-scale and show that it leads to a...

A decision maker faces a decision problem, or a game against nature. For each probability distribution over the state of the world (nature`s strategies), she has a weak order over her acts (pure strategies). We formulate conditions on these weak orders guaranteeing that they can be jointly...

We generalize the economic decision problem considered by Blackwell(1953) in which a decision maker chooses an action after observing a signal correlated to the state of nature. Unlike Blackwell's case where the feasible set is fixed, in our framework, the feasible set of actions depends on the...

Debates often serve as intitutions of mechanisms for resolving conflicts and making decisions. In this paper , we present a simple model in order to explain two phenomena concerning debate rules.

We classify the responses to owr paper " On the Interpretation of Decision Problems with Imperfect Recall" and address some of the points raised.
