Developing a good theoretical understanding of the role of trust in IR (such as in the events leading to the end of the Cold
War) is still an open problem. Most game-theoretic studies of trust do not go beyond the limitations of an (ontologically)
individualistic paradigm, thus assuming a pre-defined set of individual strategies. Yet, it is a fact that the predicament
of collective trust is empirically resolved in many situations. This paper suggests a new game-theoretic approach—Quantum
Game Theory (QGT)—to understand and explain how the predicament of trust is resolved. In a quantum game of trust the actors
play the game by simultaneously collectively reconstructing the strategic environment in such a way as to become mutually
strategically entangled. Quantum strategic entanglement allows trust to emerge between the two actors without assuming a need
for signaling, prior “contract” type of arrangement, or any form of third-party communication. The paper develops and solves
such a model of quantum game of trust 相似文献

Explaining Diversities in Age-Specific Life Expectancies and Values of Life Saving: A Numerical Analysis 总被引:1,自引:0,他引:1
To what extent can life protection account for observed diversities in age-specific life expectancies across individuals and over time? We provide answers via calibrated simulations of a life-cycle model where life’s end is stochastic, and age-specific mortality hazards are endogenous outcomes of life protection, set jointly with life insurance and annuities. Our model links mortality hazards and values of life saving (VLS) as “dual variables”, and offers new insights about the measurement of VLS. Life protection is estimated to account for non-trivial portions of observed levels and inequalities in life expectancies and empirical estimates of VLS by age and education, and over time. 相似文献

This paper considers a range of infinite exchange problems, including one recent example discussed by Barrett and Arntzenius, and propose a general taxonomy based on cardinality considerations and the possibility of identifying and tracking the units of exchange. 相似文献

Investigating Risky Choices Over Losses Using Experimental Data 总被引:1,自引:0,他引:1

We conduct a battery of experiments in which agents make choices from several pairs of all-loss-lotteries. Using these choices, we estimate a representation of individual preferences over lotteries. We find statistically and economically significant departures from expected utility maximization for many subjects. We also estimate a preference representation based on summary statistics for behavior in the population of subjects, and again find departures from expected utility maximization. Our results suggest that public policies based on an expected utility approach could significantly underestimate preferences and willingness to pay for risk reduction.JEL Classification: C91, D81 相似文献

Updating Subjective Risks in the Presence of Conflicting Information: An Application to Climate Change 总被引:3,自引:0,他引:3
Willingness to support public programs for risk management often depends on individual subjective risk perceptions in the face of uncertain science. As part of a larger study concerning climate change, we explore individual updated subjective risks as a function of individual priors, the nature of external information, and individual attributes. We examine several rival hypotheses about how subjective risks change in the face of new information (Bayesian updating, alarmist learning, and ambiguity aversion). The source and nature of external information, as well as its collective ambiguity, can have varying effects across the population, in terms of both expectations and uncertainty.JEL Classification D8, Q51, Q54 相似文献

Using data from Current Population Survey Tobacco Use Supplements spanning 1992–2002, this study shows that smokers who plan to quit smoking are more supportive of regulations than are other smokers. Failed quitters who plan to try again are more supportive of restrictions than are smokers planning to quit for the first time. These findings indicate that many smokers support regulatory restrictions to reduce their costs of quitting by exploiting the discipline offered by regulatory control. From 1992 to 2002, support for smoking restrictions in public areas rose dramatically among both nonsmokers and smokers.JEL Classification: I180, I120, H000 相似文献

This paper proposes a learning-efficiency explanation of modular structure in language. An optimal grammar arises as the solution to the problem of learning a language from a minimal number of observations of instances of the use of the language. Agents face symmetry constraints that limit their ability to make a priori distinctions among symbols used in the language and among objects (interpreted as facts, events, speakers intentions) that are to be represented by messages in the language. It is shown that if it is commonly known that the object space is modular and messages are strings, then modularity of the language is sufficient and (essentially) necessary for learning efficiency.

性别差异是言语交际中普遍存在的社会现象。从语用学的视角出发,以美剧《绝望主妇》中的异性会话作为语料,从合作原则、礼貌原则和面子论的遵守和违反三方面对英语异性会话中的性别语言差异进行了对比和分析。研究结果表明,女性在交际中更倾向于采取合作的态度,遵循礼貌原则,维护对方的面子;男性在交际中易违背合作原则和礼貌原则,威胁对方的面子。 相似文献

The article proposes a functional approach as a framework for the analysis of human well-being. The model posits that the
adaptive role of hedonic feelings is to regulate stability and homeostasis in human systems, and that these feelings basically
are created in states of equilibrium or assimilation. To regulate change and growth, a distinct set of feelings exists, which
may be labeled eudaimonic feelings. Eudaimonic feelings are produced to motivate behavior in challenging environments, when
a quick return to equilibrium is dysfunctional, or when accommodation of cognitive structures is needed for a stimulus or
event to be perceived as meaningful. It was hypothesized that a trait-like concern for evaluation of outcomes in terms of
goodness or badness, referred to as hedonic orientation, will moderate the relation between equilibrium/assimilation and hedonic
feelings. The model also includes the concept of eudaimonic orientation, reflecting a stable tendency to get involved in challenging
activities and to create and strive after demanding goals. It was hypothesized that a eudaimonic, and not a hedonic, orientation
moderates hedonic feelings in challenging episodes. Three different studies gave empirical support to the model. 相似文献
