We consider a group of strategic agents who must each repeatedly take one of two possible actions. They learn which of the two actions is preferable from initial private signals and by observing the actions of their neighbors in a social network. We show that the question of whether or not the agents learn efficiently depends on the topology of the social network. In particular, we identify a g...

2.1 Definition The basic model of decision-making by a single agent consists of a set of possible actions and a preference relation over this set. The simplest theory of the agent’s behavior is that she chooses a member of the set that is best according to the preference relation. The model of a strategic game extends this model to many agents, who are referred to as players. Each player has a ...

We discuss a new concept of agent programs that combines logic programming with reasoning about actions. These agent logic programs are characterized by a clear separation between the specification of the agent’s strategic behavior and the underlying theory about the agent’s actions and their effects. This makes it a generic, declarative agent programming language, which can be combined with an...

This study aims to analyze whether the rehabilitation of cancer surviving patients (CSPs) can be better organized. The data for this paper consists of focus group interviews (FGIs) with CSPs, general practitioners (GPs) and hospital physicians. The analysis draws on the theoretical framework of Jürgen Habermas, utilizing his notions of 'the system and the life world' and 'communicative and stra...

Player A participant in a game. Action set The set of actions that a player may choose. Action profile A list of actions, one for each player. Payoff The utility a player obtains from a given action profile. 1 Definition of the subject and its importance Game theory concerns the interaction of decision makers. This interaction is modeled by means of games. There are various approaches to constr...

METHODS The case group (n = 25) was composed of caregivers of children under 60 months of age who underwent accidental oral poisoning and were treated at two reference hospitals in Porto Alegre, southern Brazil, and recorded in the Toxicology ...

This theoretical article introduces the construct of CEO celebrity in order to explain how the tendency of journalists to attribute a firm’s actions and outcomes to the volition of its CEO affects such firm. In the model developed here, journalists celebrate a CEO whose firm takes strategic actions that are distinctive and consistent by attributing such actions and performance to the firm’s CEO...

We use eye-tracking technique to test whether players’ actions are consistent with their expectations of their opponent’s behavior. Participants play a series of two-player 3 by 3 one shot games and state their beliefs about which actions they expect their counterpart to play (first-order beliefs) or about which actions their counterparts expect them to play (second-order beliefs). We perform a...
