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

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

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

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

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.

This paper studies the optimal financing (capital structure) of entrepreneurial activity in the context of risk-aversion by incorporating the deadweight costs of bankruptcy and taxes. Unlike the extreme debt ratio (corner solution) predicted by scholars using linear models, this paper provides unique interior results for risk-free as well as risky debt, irrespective of corporate taxes. The paper also shows the necessary and sufficient conditions for both forms of debt, and the pareto-optimality of one over the other. The important findings of this paper are: (i) the existence of an equilibrium, where the borrowing interest rate is greater than the lending rate, despite the violation of Fisher separation theorem (1930); (ii) wealth plays a critical role in determining the debt ratio and the equilibrium risk-free rate of interest, complementing the De Meza and Webb (1987 and 1999) studies; (iii) an explanation for the preferred stock and income bond puzzles, extending Fooladi et al. (1991) and McConnell and Schlarbaum (1991). 相似文献

The aim of this study was to uncover patterns of pedestrian crashes. In the first stage, 34,178 pedestrian-involved crashes occurred in Iran during a four-year period were grouped into homogeneous clusters using a clustering analysis. Next, some in-cluster and inter-cluster crash patterns were analysed. The clustering analysis yielded six pedestrian crash groups. Car/van/pickup crashes on rural roads as well as heavy vehicle crashes were found to be less frequent but more likely to be fatal compared to other crash clusters. In addition, after controlling for crash frequency in each cluster, it was found that the fatality rate of each pedestrian age group as well as the fatal crash involvement rate of each driver age group varies across the six clusters. Results of present study has some policy implications including, promoting pedestrian safety training sessions for heavy vehicle drivers, imposing limitations over elderly heavy vehicle drivers, reinforcing penalties toward under 19 drivers and motorcyclists. In addition, road safety campaigns in rural areas may be promoted to inform people about the higher fatality rate of pedestrians on rural roads. The crash patterns uncovered in this study might also be useful for prioritizing future pedestrian safety research areas. 相似文献
