We develop a simple agent-based financial market model in which heterogeneous speculators apply technical and fundamental analysis to trade in two different stock markets. Speculators' strategy/market selections are repeated at each time step and depend on predisposition effects, herding...

The Precautionary Principle has been proposed as a basis for making decisions about environmental issues but remains controversial. Using a model of inductively justified propositions about awareness, this paper shows how the Precautionary Principle may be interpreted as a heuristic guide for...

We develop a model of games with awareness that allows for differential levels of awareness. We show that, for the standard modal-logical interpretations of belief and awareness, a player cannot believe there exist propositions of which he is unaware. Nevertheless, we argue that a boundedly...

We focus on syntactic aspects of di¤erential awareness that give rise to contractual disputes. Boundedly rational parties use a common language, but do not share a common understanding of the world, leading to ambiguity in both syntactic and semantic forms. In contractual relationships,...

We focus on aspects of differential awareness that give rise to contractual disputes. Parties to a contract are boundedly rational as the state space available to them is coarser than the complete state space. Hence, they may disagree as to which state of the world has occurred, and therefore as...

We formulate a dynamic framework for an individual decision-maker within which discovery of previously unconsidered propositions is possible. Using a standard game-theoretic representation of the state space as a tree structure generated by the actions of agents (including acts of nature), we...

Abstract: The precautionary principle has been proposed as a basis for making decisions about envi- ronmental issues but remains controversial. Using a model of inductively justified propositions about awareness, this paper shows how the precautionary principle may be interpreted as a heuristic...

We give a formal treatment of optimal risk sharing contracts in the face of ambiguity. The central idea is that boundedly rational individuals do not have access to a language sufficiently rich to describe all possible states of nature. The ambiguity in a contract arises from contractual clauses...

We present a formal treatment of contracting in the face of ambiguity. The central idea is that boundedly rational individuals will not always interpret the same situation in the same way. More specifically, even with well defined contracts, the precise actions to be taken by each party to the...

We consider the optimality of liquidated damages contracts in a setting of contractual ambiguity and potential for disputes. We show that when parties are ambiguity averse enough, they will optimally choose liquidated damages contracts and sacrifice risk sharing opportunities.
