Preference-Based Unawareness
Schipper, Burkhard C - Volkswirtschaftliche Fakultät, … - 2011
Morris (1996, 1997) introduced preference-based definitions of knowledge of belief in standard state-space structures … defining unawareness and knowledge in terms of preferences over acts in unawareness structures and showing their equivalence to … the epistemic notions of unawareness and knowledge, we try to build a bridge between decision theory and epistemic logic …

Thomas S. Schelling: game theory and indirect communication
Estrada, Fernando - Volkswirtschaftliche Fakultät, … - 2010
In their recent work Thomas S. Schelling (2007, 2010), reiterating original arguments about game theory and its applications to social sciences. In particular, game theory helps to explore situations in which agents make decisions interdependent (strategic communication). Schelling's originality...

Game theory on strategic communication: an approach from Thomas S. Schelling

Unawareness, Beliefs and Speculative Trade
Heifetz, Aviad; Meier, Martin; Schipper, Burkhard C - Volkswirtschaftliche Fakultät, … - 2009
We define a generalized state-space model with interactive unawareness and probabilistic beliefs. Such models are desirable for potential applications of asymmetric unawareness. We compare unawareness with probability zero belief. Applying our unawareness belief structures, we show that the...

Dynamic Unawareness and Rationalizable Behavior
Heifetz, Aviad; Meier, Martin; Schipper, Burkhard C - Volkswirtschaftliche Fakultät, … - 2009
We define generalized extensive-form games which allow for mutual unawareness of actions. We extend Pearce's (1984) notion of extensive-form (correlated) rationalizability to this setting, explore its properties and prove existence. We define also a new variant of this solution concept, prudent...

Prudent rationalizability in generalized extensive-form games
Heifetz, Aviad; Meier, Martin; Schipper, Burkhard C - Volkswirtschaftliche Fakultät, … - 2011
We define an extensive-form analogue of iterated admissibility, called Prudent Rationalizability (PR). In each round of the procedure, for each information set of a player a surviving strategy of hers is required to be rational vis-a-vis a belief system with a full-support belief on the...

Speculative Trade under Unawareness: The Infinite Case
Meier, Martin; Schipper, Burkhard C - Volkswirtschaftliche Fakultät, … - 2010
We generalize the "No-trade" theorem for finite unawareness belief structures in Heifetz, Meier, and Schipper (2009) to the infinite case.

Revealed Unawareness
Schipper, Burkhard C - Volkswirtschaftliche Fakultät, … - 2010
I develop awareness-dependent subjective expected utility by taking unawareness structures introduced in Heifetz, Meier, and Schipper (2006, 2008, 2009) as primitives in the Anscombe-Aumann approach to subjective expected utility. I observe that a decision maker is unaware of an event if and...

Language and argumentation in the controversy economic
Estrada, Fernando - Volkswirtschaftliche Fakultät, … - 2010
This article offers an approach to the general structure of the controversy in economy. In our case we adopted a perspective to study a particular aspect of the rhetoric that comes from the context of a particular controversy: the controversy on the advantages of the free commerce between Daly...

Cooperation through Imitation and Exclusion in Networks
Mengel, Friederike; Fosco, Constanza - Volkswirtschaftliche Fakultät, … - 2007
We develop a simple model to study the coevolution of interaction structures and action choices in prisoners' dilemma games. Agents are boundedly rational and choose both actions and interaction partners via payoff-biased imitation. The dynamics of imitation and exclusion yields polymorphic...
