Our paper reconsiders the triadic design proposed by Cox (Games and Economic Behavior 46:260–281, 2004) to identify trust and reciprocity in investment games. Specifically, we extend the design in two directions. First, we collect information on investors’ choices by using both the direct-response (as does Cox) and strategy methods. Using the latter, we are able to condition reciprocity on initial inequality, which is endogenous when investigating reciprocity. We demonstrate that the triadic design provides evidence for reciprocity once that initial inequality is considered. Second, we elicit expectations and test their coherence with the triadic outcomes. By examining the relationship between trust actions and expected gains, we analyze whether investors’ expectations are consistent with their behavior. Finally, we test for the existence of an emotional bias, i.e., whether expectation mismatches induce trustees to change actual choices from the planned ones. 相似文献

Estimating the Marginal Contribution to Systemic Risk by A CoVaR‐model Based on Copula Functions and Extreme Value Theory 下载免费PDF全文
Annalisa Di Clemente 《Economic Notes》2018,47(1):69-112
In this paper, we quantify the contribution to systemic risk of a single financial institution by utilizing a analytical framework based on the principles of Extreme Value Theory (EVT) for modelling the marginal distributions and on the properties of copula functions for describing the dependence structure between the financial system and the single financial institution. Among the several systemic risk measures proposed nowadays by academics and estimated by public data, we choose to adopt as systemic risk metric the Conditional Value‐at‐Risk (CoVaR). We select a co‐risk measure like the CoVaR because of its macro‐dimension that allows us to integrate the dependence structure of the single financial institution and of the whole financial system in the systemic risk measurement. While the copula functions have been utilized in some pioneer studies on this area, the EVT principles have not yet been implemented in such a context of systemic risk contribution measurement. 相似文献

The study proposes the implementation of an intermediation model in supply chains, integrating game theory and fuzzy logic, to represent the characteristic aspects of a bilateral bargaining with incomplete information where supplier–customer relationships are indirectly managed by a third party agent.The choice of combining these theories comes out from the necessity of smoothing the peculiar elements of the two analysis tools that, in describing real situations, present many potentialities of reciprocal adaptation. The scope is to combine a formal structure that could figure out the interrelations among actors involved in a strategic decisional context, with a mathematical elaboration of natural imprecision, uncertainty and incompleteness of data and information.The model derives from the theoretic foundation of Spulber [1999. Market Microstructure. Cambridge University Press, Cambridge, UK] and Rubinstein [1982. Perfect equilibrium in a bargaining model. Econometrica 50(1), 97–109] that, compared to the classical framework of asymmetric information and bid-spread problem by Harsanyi [1967. Games with incomplete information played by “Bayesian” players. I. The basic model. Management Science 14, 159–182], describe the process through the definition of new parameters such as bargaining power and breakdown probability. The contribution to the research is enriched by fuzzyfication process of data, considering Qi et al. [2005. Design retrieval technology of fuzzy customer requirements. In: World Congress on Mass Customization and Personalization] experiences, to build a framework that could transform inputs from the transaction, agents and market in an output that could regulate the possible concessions and the opportunity of accepting or refusing an offer. 相似文献

职业安全规制问题研究:基于法经济学的视角 总被引:2,自引:0,他引:2
控制和减少职业伤害,救济遭受职业伤害的劳动者,维护职业安全,是任何一个民主、法制、健康和谐的社会必须高度重视的社会经济问题,也是政府实施社会性规制的重要领域。我国国民经济高速增长的背后隐藏着巨大的社会成本,包括越来越严重的职业安全问题。各类生产安全事故的频繁发生,职业病发病人数的不断增加,折射出我国劳工状况不容乐观、劳动者权利未能得到有效保护的现实。在建设社会主义和谐社会的大背景下,应该从完善政府社会性规制入手寻求破解之道。 相似文献

The Easterlin Paradox refers to the fact that happiness data are typically stationary in spite of considerable increases in income. This amounts to a rejection of the hypothesis that current income is the only argument in the utility function. We find that the happiness responses of around 350,000 people living in the OECD between 1975 and 1997 are positively correlated with the level of income, the welfare state and (weakly) with life expectancy; they are negatively correlated with the average number of hours worked, environmental degradation (measured by SOx emissions), crime, openness to trade, inflation and unemployment; all controlling for country and year dummies. These effects separate across groups in a pattern that appears broadly plausible (e.g., the rich suffer environmental degradation more than the poor). Based on actual changes from 1975 to 1997, small contributions to happiness can be attributed to the increase in income in our sample. Interestingly, the actual changes in several of the ‘omitted variables’ such as life expectancy, hours worked, inflation and unemployment also contribute to happiness over this time period since life expectancy has risen and the others have, on average, fallen. Consequently the unexplained trend in happiness is even bigger than would be predicted if income was the only argument in the utility function. In other words, introducing omitted variables worsens the income-without-happiness paradox. 相似文献

Although oil spills from tanker accidents receive the most publicity, most vessel spills are not the result of accidents but of oil transfer activities. We investigate determinants of the size of vessel oil transfer spills as well as the effectiveness of Coast Guard enforcement activities in reducing their size. Vessel out-of-water and in-water oil transfer spillage functions are estimated utilizing tobit regression and detailed data on individual vessel oil transfer spills as well as Coast Guard safety/environmental enforcement activity data for the 1991–1995 period. Our estimation results suggest that Coast Guard hull but not machinery inspections are effective in reducing both out-of-water and in-water spills; patrols by air, but not by boat, are effective in reducing out-of-water spills; but neither is effective in reducing in-water spills. The results also show that the type of vessel (oil- and non-oil-cargo), vessel characteristics, vessel operations, weather/visibility conditions, and waterway type are determinants of post OPA-90 vessel oil transfer spills. 相似文献
