The job classification literature has been dominated by a micro‐level orientation reflective of the needs of specialists in human resources. In contrast, we take a multidisciplinary approach involving both micro‐ and macro‐level variables to propose a relatively simple system comprised of four job classes. Our model isintended to inform management as to the type and mix of controls (e.g., centralization, formalization, and various human resources policies) that could be applied to different job types to optimally promote the overall goals of the organization. Fuzzy numbers analysis is employed to illustrate the application of the system using four jobs in a car dealership in Spain. Copyright © 2012 ASAC. Published by John Wiley & Sons, Ltd.  相似文献

This paper uses fractional integration models to describe the long‐run dependence of nominal exchange rates in Central and Eastern European countries (CEECs). The analysis is validated using nonparametric, semiparametric and parametric techniques. From comparing the results across the three approaches, it was clear that mean reversion takes places only for the euro exchange rates in Bulgaria, Estonia, and Slovenia. Other exchange rates based on the euro also display mean reversion with the parametric methods. For the US dollar rates, the unit‐root null hypothesis cannot be rejected in any single country, indicating that shocks affecting the exchange rates against the US dollar are of a permanent nature, while those directed against the euro are less persistent, and tend sometimes to disappear in the long run. Policy implications are derived.  相似文献

We study the sovereign default model that has been used to account for the cyclical behavior of interest rates in emerging market economies. This model is often solved using the discrete state space technique with evenly spaced grid points. We show that this method necessitates a large number of grid points to avoid generating spurious interest rate movements. This makes the discrete state technique significantly more inefficient than using Chebyshev polynomials or cubic spline interpolation to approximate the value functions. We show that the inefficiency of the discrete state space technique is more severe for parameterizations that feature a high sensitivity of the bond price to the borrowing level for the borrowing levels that are observed more frequently in the simulations. In addition, we find that the efficiency of the discrete state space technique can be greatly improved by (i) finding the equilibrium as the limit of the equilibrium of the finite-horizon version of the model, instead of iterating separately on the value and bond price functions and (ii) concentrating grid points in asset levels at which the bond price is more sensitive to the borrowing level and in levels that are observed more often in the model simulations. Our analysis is also relevant for the study of other credit markets.  相似文献

This note studies price decisions in a duopoly industry where firms have private information over the degree of product differentiation (product-type). A Bayesian-Nash price solution is derived assuming firms maximize their ??certainty-equivalent?? profit levels. The comparative-statics indicate that increased risk aversion over the rival??s product triggers price competition. Consequently, the results of the study suggest revealing information is a higher reward strategy than concealing information in situations where rivals have asymmetric information over product type. These findings contribute to the industrial economic literature by generalizing the Bertrand equilibrium in an asymmetric information game model.  相似文献

Various theoretical approaches uphold the relevance of the relationship between the form of management and performance. Different management styles influence the relationships of agencies [Jensen, M.C. (1998). Foundations of organizational strategy. Cambridge, MA: Harvard University Press], the cost of governing transactions [Williamson, O.E. (1985). The economics institutions of capitalism: Firms, markets, relational contracting. New York, NY: Free Press], and the allocation of resources between the exploitation and exploration of activities [March, J.G. (1991). Exploration and exploitation in organizational learning. Organization Science, 2(1), 71–87], and this is manifested in firm performance. In light of these assumptions, this article presents an empirical verification of the relationship between the management of franchises and their performance, examining how different styles of management on the part of franchisers over their franchisees have significant effects on the growth and profits of franchiser firms.  相似文献

As the relative effectiveness of physical resources decreases toward parity with rivals due to their fungibility, the firm's marketplace position, established by managers with a particular set of inter-culturally attuned set of personal values, may be the key antecedent in creating competitive strength in the firm. The research question addressed is how creative are culturally diverse managers; are managers from certain countries more creative than adaptive?We tested hypotheses in a cross-cultural setting based on the survey responses of 1365 managers operating in eight countries located in four culturally diverse regions of the world.Our study shows that managers are both creative and adaptive but the mixture of creative and adaptive behaviour varies depending on region and country and even within countries. Furthermore, the results confirm that creativity among managers in some countries is similar but large differences also exist between countries.  相似文献

Current practices for the treatment of the physically and/or mentally handicapped prescribe meaningful job activity as a means towards both a more fulfilling life and societal integration. In many countries, these practices have facilitated the development of many Sheltered Work Centres for Disabled.In the case study presented, a reengineering process is done starting from individual workplaces where only certain workers were capable of assembling the entire product, and finishing with an assembly line implementation. It is revealed how the traditional division of work in single tasks, typical in assembly lines, becomes a perfect tool for making certain worker disabilities invisible, providing new jobs for disabled people; always taking into account certain special constraints that are analysed.  相似文献

Alfred Chandler once described the U.S. conglomerate movement of the 1960s and '70s as an "historical aberration and a 'disaster." And the recent trend in corporate mergers and acquisitions away from "diversifying" acquisitions would seem to confirm Chandler's argument.
In what constitutes yet another piece of evidence in support of Chandler's argument, the authors of this article conducted a study of changes in debt and equity values in 260 stock-forstock mergers completed between 1963 and 1996. With a sample almost evenly divided between conglomerate and "related" mergers, the authors report significant net wealth gains for all securityholders as a group in "related" mergers, but generally insignificant net gains for securityholders in conglomerate mergers. Not surprisingly, target firm shareholders experienced net wealth gains in both kinds of acquisitions; but for acquiring company shareholders, there was a striking difference: economically and statistically significant gains for acquirers in related transactions, and significant losses for acquirers in conglomerate deals.
Perhaps the biggest surprise of the study, however, was that even the bondholders of acquirers in related mergers benefited more than bondholders in conglomerate deals. The result is surprising because, to the extent bondholders benefit from corporate diversification, one would expect the opposite result. That bondholders in related mergers experience larger wealth increases than those of conglomerate acquirers is just one more sign of the dramatic differences in total value created by the two kinds of mergers.  相似文献

Road traffic injuries in general and pedestrian injuries in particular are a major public health problem in Mexico, especially in large urban areas. Analysis of mortality and road crashes at the national level was done using routine data recorded on death certificates. Fatality rates for different age groups were estimated by region for the year 2000. These data were supplemented by a cross-sectional study of pedestrian injuries in Mexico City based on death certificates information for pedestrians who lived and died in Mexico City between 1994 and 1997. Participant observation of physical spaces where crashes occurred was carried out. The spaces were filmed and in-depth interviews of survivors conducted. Road traffic crashes were responsible for approximately 17,500 deaths in Mexico during 2000. The mean age of the victims was 37 years. Mexico lost an average of 30 years of productive life for each individual who died in a traffic crash – 525,000 years in 2000. An estimated 9500 (54.3%) of all fatalities were pedestrians, and for every pedestrian death there were 13 others who sustained nonfatal injuries requiring medical care. The overall crude mortality rate for pedestrian injuries in Mexico City was 7.14 per 100,000 (CI 6.85-7.42). A concentration of deaths was observed in 10 neighborhoods at specific types of street environments. The underlying factors included dangerous crossings and the absence or inadequacy of pedestrian bridges, as well as negative perceptions of road safety by pedestrians. In conclusion, this study demonstrates the importance of elucidating the underlying contextual determinants of pedestrian injuries.  相似文献

This note reinforces the results in a paper by Sen (International Journal of Industrial Organization, vol. 11, 1993, pp. 123–37). It is shown that his assumption that the incentive schemes in a two‐period model are the same for the two periods is not necessary for the results: only the long‐term nature of contracts with managers matters.  相似文献
