We compare behavior in modified dictator games with and without role uncertainty. Subjects choose between a selfish action,
a costly surplus creating action (altruistic behavior) and a costly surplus destroying action (spiteful behavior). While costly
surplus creating actions are the most frequent under role uncertainty (64%), selfish actions become the most frequent without
role uncertainty (69%). Also, the frequency of surplus destroying choices is negligible with role uncertainty (1%) but not
so without it (11%). A classification of subjects into four different types of interdependent preferences (Selfish, Social
Welfare maximizing, Inequity Averse and Competitive) shows that the use of role uncertainty overestimates the prevalence of
Social Welfare maximizing preferences in the subject population (from 74% with role uncertainty to 21% without it) and underestimates
Selfish and Inequity Averse preferences. An additional treatment, in which subjects undertake an understanding test before
participating in the experiment with role uncertainty, shows that the vast majority of subjects (93%) correctly understand
the payoff mechanism with role uncertainty, but yet surplus creating actions were most frequent. Our results warn against
the use of role uncertainty in experiments that aim to measure the prevalence of interdependent preferences. 相似文献

This paper presents a model of innovations and endogenous economic growth with two main assumptions: first, the cost of searching
for innovations differs across innovations, and second, innovations take time to find. The paper shows that given these two
assumptions together, competition leads to patent races and to duplication of innovative activity. The paper then shows that
duplication significantly reduces the effect of scale on growth. It also shows that competitive R&D creates too much research
on easy innovations, and too little research on the difficult ones. Finally, the paper shows that risk sharing might increase
duplication and reduce growth. 相似文献

Sustaining cooperation in laboratory public goods experiments: a selective survey of the literature 总被引:5,自引:0,他引:5

I survey the literature post Ledyard (Handbook of Experimental Economics, ed. by J. Kagel, A. Roth, Chap. 2, Princeton, Princeton
University Press, 1995) on three related issues in linear public goods experiments: (1) conditional cooperation; (2) the role of costly monetary
punishments in sustaining cooperation and (3) the sustenance of cooperation via means other than such punishments. Many participants
in laboratory public goods experiments are “conditional cooperators” whose contributions to the public good are positively
correlated with their beliefs about the average group contribution. Conditional cooperators are often able to sustain high
contributions to the public good through costly monetary punishment of free-riders but also by other mechanisms such as expressions
of disapproval, advice giving and assortative matching. 相似文献

This paper posits that significant changes in 19th century British recreational travel patterns resulted from a change in
the manner in which tourists used entertaining stimuli in order to attain pleasure. Consumers no longer merely viewed arousing
stimuli, but attempted to use them to produce emotional states of being which they could partially modify to intensify pleasurable
feelings (Damasio, Looking for Spinoza: Joy, sorrow, and the feeling brain, William Heinemann, 2003). The impetus for this modification stemmed from an increasing awareness that emotional responses could be to some degree
self-cultivated, as embodied in the Romantic ethos that become popular at the time via the emergence of the paperback novel
and magazine industry (Campbell, The romantic ethic and the spirit of modern consumerism, Blackwell, 1987). By learning how to manipulate and modify mental images in a way that may not necessarily correspond with objective reality,
Romantic tourists learned to elicit pleasure through engaging of their imagination. Such a change in the mode of pleasure
seeking had important long run economic consequences for tourist regions throughout the European continent. 相似文献

资本主义经济危机是一种与资本主义制度与生俱来的现象,是资本主义无法治愈的痼疾。马克思在他有生之年经历了7次经济危机,并于19世纪40年代,开始研究资本主义周期性的生产过剩危机。通过对经济危机史的研究及密切联系资本主义经济发展实际的情况,马克思对经济危机问题的研究取得了一系列研究成果。《资本论》的问世,标志着马克思经济危机理论的完成。马克思通过对经济危机的可能性、现实性、根源和实质等方面进行了阐述,形成了比较完整的理论体系,成为研究经济危机问题的理论基石。 相似文献
