A strong equilibrium is a pure Nash equilibrium which is resilient to deviations by coalitions. We define the strong price of anarchy (SPoA) to be the ratio of the worst strong equilibrium to the social optimum. Differently from the Price of Anarchy (defined as the ratio of the worst Nash Equilibrium to the social optimum), it quantifies the loss incurred from the lack of a central designer in settings that allow for coordination.We study the SPoA in two settings, namely job scheduling and network creation. In the job scheduling game we show that for unrelated machines the SPoA can be bounded as a function of the number of machines and the size of the coalition. For the network creation game we show that the SPoA is at most 2. In both cases we show that a strong equilibrium always exists, except for a well defined subset of network creation games. 相似文献

By drawing on multi-case data, there is some evidence to suggest that total quality management (TQM) effectiveness can be viewed as a direct function of the controlling mechanisms that senior managers created prior to TQM implementation. More importantly, control tools of TQM were not used by non-managerial employees, with which they could reduce variability or achieve uniformity; rather, they were regarded as a weapon used by their managers against them. 相似文献

This study investigates how the type of offer sold online (goods vs. services) moderates the relationships between perceived experiential values and customers' attitudes towards the website. A sample of 107 e‐shoppers of services and 110 e‐shoppers of physical goods responded to a survey on their most recent e‐shopping experiences. Results support the majority of hypotheses. It was found that although offering experiential values on the site improves customers' attitudes for both physical goods and services websites, the impact is much stronger in the case of services. Theoretical and managerial contributions are discussed. 相似文献

Optimal reserve composition in the presence of sudden stops 总被引:1,自引:0,他引:1
We analytically derive optimal central bank portfolios in a minimum variance framework with two assets and transaction demands caused by sudden stops in capital inflows. In this model, transaction demands become less important relative to traditional portfolio objectives as debt to reserve ratios decrease. We empirically estimate optimal dollar and euro shares for 23 emerging market countries and find that optimal reserve portfolios are dominated by anchor currencies and, at current debt-to-reserve ratios, introducing transaction demand has a relatively modest effect for most countries. We find that, in general, the dollar acts as a safe haven currency during sudden stops for country specific and global sudden stops, increasing the optimal share of dollar bonds in central bank portfolios. Correspondingly, our model predicts that dollar shares should decline as debt-to-reserve ratios fall, as observed in recent data. We also find that the denomination of foreign currency debt has little importance for optimal reserve portfolios. 相似文献

ABSTRACT This study first develops an empirically based Western charismatic leadership profile. Using confirmatory factor analysis, the profile is compared with a profile of Iranian managers. The results demonstrate that despite major cultural differences in the two countries, there are core similarities in the profiles across the two cultures. The Canadian charismatic profile of vision, tenacity, intellectual challenge, self-sacrifice, and eloquence is substantially confirmed within the Iranian sample. But we also show that Iranian managers' ratings are significantly lower than those of the Canadian managers, indicating potentially different behavioural manifestations. The paper speculates that while the differences are probably due to cultural differences, the similarities may be due to universal intrinsic human desire for morality, autonomy, and achievement. 相似文献

This study aims to theoretically integrate quality factors of both medical and hospitality services in medical tourism. Medical tourism comprises both medicine and tourism. Although the core product in medical tourism is medical treatment, attractive hospitality and travel options are also essential. Despite the dual nature of medical tourism, the two aspects of this concept have not been integrated in a unique framework. This study attempts to fill this gap using interpretive structural modeling (ISM). According to ISM, although factors of medical services and hospitality services are independent from each other, these factors have vital impacts on perceived value, satisfaction, and loyalty. 相似文献

This study aims to find the differences between national and international relationships in Iran and Switzerland’s Nanoscience research between 2008–2015. The results show significant differences some of which are attributed to the general dichotomy of developed-developing countries like stronger University-Industry-Government relations in Switzerland; but others are not, especially those pertaining to bilateral relations. In summary, the Government-Industry relations in Switzerland are generally closer in this field because the emerging characteristics of Nanoscience call for more state intervention, even in the context of developed countries. Greater Government-University relations in Iran can be explained by referring to the structure of national innovation system of this country. However, the no significant differences between University-Industry relations result needs further research so that it may in turn lead to improvements of the triple-helix calculations. Lastly, some theoretical implications and further research directions are suggested at the end. 相似文献

We investigate the price discovery role of an exchange‐traded fund and the futures contract for the same market index. We find that the fund predicts the index in the subperiod after but not in the subperiod before a substantial decrease in the minimum tick size. The futures predict the index in both subperiods. The results are consistent with the view that the factors leading to successful price discovery do not depend on zero investment, as in futures markets, but do depend on a small tick size. © 2003 Wiley Periodicals, Inc.

Since September 2000, as a result of mobility restrictions, the supply of Palestinian workers competing for local jobs in the West Bank has increased by about fifty percent. This paper takes advantage of this unique natural experiment to study the effects of labor supply shocks on labor market outcomes. Using quarterly information on wages and employment in each city in the West Bank, the paper analyzes the short-run adjustment of labor markets to a large inflow of workers separately from the effects of political instability. The results suggest that low-skilled wages are adversely affected by an increase in the supply of low- and high-skilled workers, while high-skilled wages are only weakly negatively related to an increase in their own supply. This is consistent with a scenario in which high-skilled workers compete for low-skilled jobs, pushing the low-skilled into unemployment. This latter hypothesis is confirmed by analyzing the effects of changes in labor supply on unemployment. 相似文献
