Whereas both the Allais paradox, the first empirical challenge of the classical rationality assumptions, and learning have
been the focus of many experimental investigations, no experimental study exists today into learning in the pure context of
the Allais paradox. This paper presents such a study. We find that choices converge to expected utility maximization if subjects
are given the opportunity to learn by both thought and experience, but less so when they learn by thought only. To the extent
that genuine preferences should be measured with proper learning and incentives, our study gives the first pure demonstration
that irrationalities such as in the Allais paradox are less pronounced than often thought.

A cooperative game with transferable utility–or simply a TU-game– describes a situation in which players can obtain certain payoffs by cooperation. A value function for these games assigns to every TU-game a distribution of payoffs over the players. Well-known solutions for TU-games are the Shapley and the Banzhaf value. An alternative type of solution is the concept of share function, which assigns to every player in a TU-game its share in the worth of the grand coalition. In this paper we consider TU-games in which the players are organized into a coalition structure being a finite partition of the set of players. The Shapley value has been generalized by Owen to TU-games in coalition structure. We redefine this value function as a share function and show that this solution satisfies the multiplication property that the share of a player in some coalition is equal to the product of the Shapley share of the coalition in a game between the coalitions and the Shapley share of the player in a game between the players within the coalition. Analogously we introduce a Banzhaf coalition structure share function. Application of these share functions to simple majority games show some appealing properties. 相似文献

This article takes the increased interest in the relation between culture and social policy as a starting point, and discusses how this increasing attention can be understood as the result of contextual factors such as economic, social and academic trends. It discusses these matters and at the same time reviews briefly some of the main findings of studies that contain a cultural perspective in analysing social policy. A second issue concerns the specific character of cultural perspectives in such analyses. Thus far, most studies in the field have been guided by a notion of culture as consisting of the values, norms and beliefs of welfare state actors. Recently, this notion has been questioned by advocates of the so-called 'cultural turn', who suggest that a radical change in the cultural analysis of social policy is required. The article concludes with a discussion of their claims. 相似文献

Since the early 1980s Australian public policy has undergone the most major transformation since Federation. This transformation has been underwritten by two key principles: liberalism – the view that citizens are autonomous individual actors whose interests are best served when they are free from coercive government interventions into individual action; and marketisation – the belief that free markets are arenas which best enable individual autonomy and produce efficient economic outcomes. These principles define ‘neoliberalism’ or ‘hard liberalism‘. After summarising the major policy changes identified with neoliberalism in Australia, the paper introduces a new research project that examines its impact on socioeconomic inequality, gender inequality and politics and culture. Inspection of relevant data indicates that there are important trends in inequality, public opinion and political behaviour that warrant this investigation. 相似文献

A negative effect of good health on the instrumental support received can be viewed as an effect of the mobilization of helpers. A positive effect of good health on the personal network size and the instrumental support given demonstrates that people in poor health have difficulty actively maintaining their relationships. Furthermore, the support received and given is positively related to the support given and received in the past. In four waves of a seven–year longitudinal study, personal interviews were conducted with 2,302 older Dutch adults (aged 60 to 85) who live on their own. The hypotheses have been confirmed. An implication is that investing in relationships by giving support might pay off in times of need. 相似文献
