Drama theory and its relation to game theory. Part 2: Formal model of the resolution process 总被引:2,自引:0,他引:2
Nigel Howard 《Group Decision and Negotiation》1994,3(2):207-235
In a drama, characters' preferences and options change under the pressure of pre-play negotiations. Thus they undergo change and development. A formal model of dramatic transformation is presented that shows how the core of a drama is transformed by the interaction among the characters into a strict, strong equilibrium to which they all aspire. The process is seen to be driven by actors' reactions to various paradoxes of rationality. 相似文献

Drama theory and its relation to game theory. Part 1: Dramatic resolution vs. Rational solution 总被引:1,自引:0,他引:1
Nigel Howard 《Group Decision and Negotiation》1994,3(2):187-206
Drama theory differs from game theory in that it does not regard actors' preferences and perceived opportunities as fixed, but as capable of being changed by the actors themselves under the pressure of pre-play negotiations. Thus characters in a drama undergo change and development. A manyperson, multiphase theory of dramatic transformation is presented, showing how thecore of a drama (in the sense of game theory) is transformed by the interaction between the characters into a strict, strong equilibrium to which they all aspire. The process of dramatic transformation is shown to be driven by actors' reactions to various paradoxes of rationality; it is proved that when all these paradoxes have been overcome, a full dramatic resolution has been reached, satisfying actors' emotional and moral demands, as well as the demands of rationality. 相似文献

This paper considers a public-good economy with congestion, where participants jointly produce a public good from input of a private good. This economic model gives rise to a transferable-utility game, the profit game, that depends on consumer preferences and a congestion parameter. The simplicity of the game allows the maximum level of congestion that guarantees the nonemptiness of the core of the economy to be determined. It is known that the sustainability of the Lindahl equilibrium in the core of the economy depends on the distribution of profits. In this paper two distributions of profits are compared: the Lindahl solution and the marginal-contribution solution. The latter is more often in the core than the Lindahl solution which in turn Lorenz-dominates the marginal-contribution solution. 相似文献

This paper examines signalling when the sender exerts effort and receives benefits over time. Receivers only observe a noisy public signal about the effort, which has no intrinsic value.The modelling of signalling in a dynamic context gives rise to novel equilibrium outcomes. In some equilibria, a sender with a higher cost of effort exerts strictly more effort than his low-cost counterpart. The low-cost type can compensate later for initial low effort, but this is not worthwhile for a high-cost type. The interpretation of a given signal switches endogenously over time, depending on which type the receivers expect to send it. 相似文献

Suppose legislators represent districts of varying population, and their assembly's voting rule is intended to implement the principle of one person, one vote. How should legislators' voting weights appropriately reflect these population differences? An analysis requires an understanding of the relationship between voting weight and some measure of the influence that each legislator has over collective decisions. We provide three new characterizations of weighted voting that embody this relationship. Each is based on the intuition that winning coalitions should be close to one another. The locally minimal and tightly packed characterizations use a weighted Hamming metric. Ellipsoidal separability employs the Euclidean metric: a separating hyper-ellipsoid contains all winning coalitions, and omits losing ones. The ellipsoid's proportions, and the Hamming weights, reflect the ratio of voting weight to influence, measured as Penrose–Banzhaf voting power. In particular, the spherically separable rules are those for which voting powers can serve as voting weights. 相似文献

This paper studies strategic transmission of verifiable information with reporting costs that continuously increase in the precision of the report. Contrary to previous literature, it is shown that the unraveling result first derived by Milgrom (1981) is relatively robust to costly reporting. A separating equilibrium exists even with arbitrarily high reporting costs. Intuitively, the costs work as a signaling device and a combination of disclosure of information and costly signaling accomplishes full separation. With reporting costs there are typically multiple equilibria. For example, a pooling equilibrium exists if and only if the reporting costs are high. Finally, a separating equilibrium exists when the receiver has to make a costly effort in order to access the information in a report, as long as this cost is not too high. 相似文献

An apex game consists of one apex player and a set of minor players. We identify two key properties of apex games and use them to introduce the class of general apex games. We derive players' preferences over winning coalitions by applying strongly monotonic power indices on such a game and all its subgames and investigate whether there are core stable coalitions in the induced hedonic coalition formation game. Besides several general results, in particular, we develop conditions on the game for the Shapley–Shubik index, the Banzhaf index, and the normalized Banzhaf index. 相似文献

The present research is aimed to apply experimental techniques to study strategic behavior in one-shot-hide-and-seek games as a frame to elicit more real and elaborated business situations. To promote strategic thinking and persistence, we conducted treatments with repeated matching games among strangers, and one of them with a fixed endowment (fixed initial payment that decreases each round an amount) with the possibility of abandon in any round, retaining the remaining of endowment. In fact, effortful strategic reasoning is found in deviation of subjects’ random choices along the repetitions and abandon, loss aversion, and cultural differences seem articulate a strategic behavior. 相似文献
