The present article examines two important effects that have been given scant attention in prior studies of variable risk strategies. The first effect, reference group sensitivity, is the degree to which decision makers' aspirations are sensitive to their reference group. In this paper we...

Habermas' concept of communicative rationality, in which reason is construed in terms of the noncoercive intersubjectivity of mutual understanding and reciprocal recognition, provides a valid foundation on which the theory and practice of selves-directed learning can be developed. In an...

We describe a dynamic model of costly information sharing, where private information affecting collective-value actions is transmitted by social proximity. Individuals make voluntary contributions towards the provision of a pure public good, and information transmission about quality of...

Tuning one's shower in some hotels may turn into a challenging coordination game with imperfect information. The temperature sensitivity increases with the number of agents, making the problem possibly unlearnable. Because there is in practice a finite number of possible tap positions, identical...

I examine a setting, where an information sender conducts research into a payoff-relevant state variable, and releases information to agents, who consider joining a coalition. The agents' actions can cause harm by contributing to a public bad. The sender, who has commitment power, by designing...

This article reports the process of building a fuzzy set scale in order to value workers participation and their learning through a technical improvement project in metallurgical plants. The process starts with a practical question which stems from workers: "How can we value our own...

The tendency for the members of a corporation or government to be resistant to change is explored in a model that encompasses two endemic features of such systems. First, the social system is modeled as a hierarchy, and implicit within it is a selection process that determines who advances to...

Consider an urn filled with balls, each labeled with one of several possible collective decisions. Now let a random voter draw two balls from the urn and pick her more preferred as the collective decision. Relabel the losing ball with the collective decision, put both balls back into the urn,...

Earlier studies of the seigniorage inflation model have found that the high-inflation steady state is not stable under adaptive learning. We reconsider this issue and analyze the full set of solutions for the linearized model. Our main focus is on stationary hyperinflationary paths near the...
