Inequity and risk aversion in sequential public good games 总被引:1,自引:0,他引:1
Sabrina Teyssier 《Public Choice》2012,151(1-2):91-119
Behavioral hypotheses have recently been introduced into public-choice theory (Ostrom in American Political Science Review 92:1–22, 1998). Nevertheless, the individual intrinsic preferences which drive decisions in social dilemmas have not yet been empirically identified. This paper asks whether risk and inequity preferences are behind agents’ behavior in a sequential public good game. The experimental results show that risk aversion is negatively correlated with the contribution decision of first movers. Second movers who are averse to advantageous inequity free-ride less and reciprocate more than do others. Our results emphasize the importance of strategic uncertainty for the correct understanding of which preferences influence cooperation in social dilemmas. 相似文献

Abstract: Three‐dimensional (3D) laser scanner models of human crania can be used for forensic facial reconstruction, and for obtaining craniometric data useful for estimating age, sex, and population affinity of unidentified human remains. However, the use of computer‐generated measurements in a casework setting requires the measurement precision to be known. Here, we assess the repeatability and precision of cranial volume and surface area measurements using 3D laser scanner models created by different operators using different protocols for collecting and processing data. We report intraobserver measurement errors of 0.2% and interobserver errors of 2% of the total area and volume values, suggesting that observer‐related errors do not pose major obstacles for sharing, combining, or comparing such measurements. Nevertheless, as no standardized procedure exists for area or volume measurements from 3D models, it is imperative to report the scanning and postscanning protocols employed when such measurements are conducted in a forensic setting. 相似文献

The present study was designed to examine trajectories of personal identity coherence and confusion among Hispanic recent-immigrant adolescents, as well as the effects of these trajectories on psychosocial and risk-taking outcomes. Personal identity is extremely important in anchoring young immigrants during a time of acute cultural change. A sample of 302 recently immigrated (5 years or less in the United States at baseline) Hispanic adolescents (Mage?=?14.51 years at baseline; SD?=?0.88 years, range 14–17) from Miami and Los Angeles (47?% girls) completed measures of personal identity coherence and confusion at the first five waves of a six-wave longitudinal study; and reported on positive psychosocial functioning, depressive symptoms, and externalizing problems at baseline and at Time 6. Results indicated that identity coherence increased linearly across time, but that there were no significant changes in confusion over time and no individual differences in confusion trajectories. Higher baseline levels of, and improvements in, coherence predicted higher levels of self-esteem, optimism, and prosocial behavior at the final study timepoint. Higher baseline levels of confusion predicted lower self-esteem, greater depressive symptoms, more aggressive behavior, and more rule breaking at the final study timepoint. These results are discussed in terms of the importance of personal identity for Hispanic immigrant adolescents, and in terms of implications for intervention. 相似文献

Soft power has become China’s new diplomatic tool to spread its influence in today’s changing international landscape. The establishment of Confucius Institutes (CIs) since 2004 to promote the understanding of Chinese language and culture is a striking example of how the government promotes soft power through cultural means. Through the macro- and micro-level analysis of CIs, this study shows that CIs fail to increase the soft power of China because many countries regard CIs as a propaganda tool and a threat to academic freedom and the local community. It shows that China’s soft power is not so attractive in the eyes of receivers. In fact, China’s aggressive cultural initiatives through the establishment of CIs have triggered another version of the ‘China threat’. 相似文献

The open method of coordination (OMC) has emerged as a new policy instrument in the European context. While it was initially confined to the employment field, it has recently been applied to several other areas. The aim of this article is to provide a reconstruction of the OMC. The focus is in particular on the structure and process of the OMC, but also on the new approach to law that it proposes. The OMC differs from traditional EC methods but also from traditional soft-law mechanisms. In order to highlight those original features, the paper analyses the key steps in the evolution of a strategy, the European employment strategy, which slowly became a new mode of governance. 相似文献
