On a heterogeneous experimental oligopoly market, sellers choose a price,specify a set-valued prior-free conjecture about the others' behavior, andform their own profit-aspiration for each element of their conjecture. Weformally define the concepts of satisficing and prior-free optimality...

We experimentally investigate, in an unstructured bargaining environment with commonlyknown money payoffs, the Attraction Effect and Compromise Effect (AE and CE) in bargaining,namely a tendency for bargainers to agree to an intermediate option (CE), or to an optionthat dominates another option...

We study aggregative games in which players’ strategy sets areconvex intervals of the real line and (not necessarily differentiable)payoffs depend only on a player’s own strategy and the sum of allplayers’ strategies. We give sufficient conditions on each player’s payofffunction to...

A decision maker (DM) is asked to make choices from a set of acts, which entail both risk and uncertainty in the sense of knight (1921). Extending Raiffa's (1961) argument I show that, provided the DM can choose acts objectively randomly (by flipping her own fair coin, for instance), provided...

We provide an evolutionary foundation to evidence that in some situations humans maintain optimistic or pessimistic attitudes towards uncertainty and are ignorant to relevant aspects of the environment. Players in strategic games face Knightian uncertainty about opponents' actions and maximize...

We propose a framework in order to econometrically estimate case-based learning and apply it to empirical data from twelve 2 × 2 mixed strategy equilibria experiments. Case-based learning allows agents to explicitly incorporate information available to the experimental subjects in a simple,...

Standard choice theory assumes that the choice set is known to the decision-maker in advance. In contrast, we develop a model in which alternatives are examined sequentially and decision-makers exhibit `satis cing' attitudes. The proposed procedure includes the standard model of choice as a...

How would a boundedly rational agent react to a larger menu? I model bounded rationality as choice from an unobservable, subjective consideration subset. Consideration sets satisfy Sen's (1969) property alpha: larger objective choice sets can generate smaller consideration sets. In a...

We propose a notion of r-rationality, a relative version of satisficing behavior based on the idea that, for any set of available alternatives, individuals choose one of their r-best according to a single preference. We fully characterize the choice functions satisfying the condition for any r,...
