This article reviews the literature of commercial diplomacy during the period 1960–2014 from a management angle and is organized around four major themes: (1) government’s export/trade promotion function; (2) institutional/organizational arrangements; (3) managerial roles and activities; and (4) interaction between commercial diplomats and businesses. A complementary quantitative analysis tracing current research trends reveals the emergence of relevant publications at the end of the 1970s and a real increase after 2000. It also confirms the relative scarcity of commercial diplomacy literature focusing on the business and management dimension. Gaps in current literature are identified, and suggestions for further research are presented. 相似文献

GX气田北部地区构造、断层特征较为复杂,地质建模较困难,而约束稀疏脉冲反演是一种基于地震道的反演方法,它是在波阻趋势的约束下,用最少的反射系数脉冲达到合成记录与地震道的最佳匹配。该方法对初始模型依赖性较小,中高频部分不受初始模型的影响,其反演结果能忠于实际地震资料,分辨率与地震资料接近,保真度高。以GX气田为例,通过约束稀疏脉冲反演技术对GX气田开展储层预测,其反演结果与实测井曲线吻合较好,能客观反映地质体在横向上的变化特征,该方法适用于储层横向变化快和非均质性较强的少井区块。 相似文献

In this contribution to the use of the Harvard-style case-style method in the training of managers, a transfer problem is identified. This is manifested in the difficulties presented for many non-American students in the use of traditional case-studies. As a result, an example of a revised case method is proposed which offers more educational flexibility and better acceptability. 相似文献

This paper presents hedging strategies for European and exotic options in a Lévy market. By applying Taylor’s theorem, dynamic hedging portfolios are constructed under different market assumptions, such as the existence of power jump assets or moment swaps. In the case of European options or baskets of European options, static hedging is implemented. It is shown that perfect hedging can be achieved. Delta and gamma hedging strategies are extended to higher moment hedging by investing in other traded derivatives depending on the same underlying asset. This development is of practical importance as such other derivatives might be readily available. Moment swaps or power jump assets are not typically liquidly traded. It is shown how minimal variance portfolios can be used to hedge the higher order terms in a Taylor expansion of the pricing function, investing only in a risk‐free bank account, the underlying asset, and potentially variance swaps. The numerical algorithms and performance of the hedging strategies are presented, showing the practical utility of the derived results. 相似文献

We consider incomplete markets, where each risky asset fluctuation is a continuous semimartingale, and study a subset of Equivalent Local Martingale Measures in which Minimal Martingale Measure minimizes relative entropy.We also discuss, as special cases, some models with the risky assetfluctuation represented as a solution of some stochastic differential equations.Finally, we mention that the predictable representation property is essentialin order that Minimal Martingale Measure coincides with Minimal Entropy Martingale Measure. 相似文献

We solve Problem 234 in Statistica Neerlandica by introducing the concept of slantedness. Distributions with a decreasing Lebesgue density are slanted to the right. This is no longer true for distributions on a lattice with decreasing density. Both kinds of distributions have positive central odd moments. 相似文献

Gangaram Singh 《Employee Responsibilities and Rights Journal》2001,13(2):107-124
Employee representation is an important aspect of the employment relationship. In some countries (e.g., Germany), the government mandates employee representation. In other countries (e.g., the Commonwealth), employers voluntarily recognize employee representatives. In the United States, employees must earn their right to be represented in a certification process that results in collective bargaining. With the significant reduction of union membership in the United States, this representation model is in decline. Other forms of participation have not picked up the slack. Hence, there remains a significant representation gap. In this paper, I describe and analyze several solutions to the representation gap. Both unorganized and organized forms of employee representation are considered. 相似文献

The changeover to the euro elicited an upsurge of research on the effects of the new currency on consumers’ conversion strategies, price estimates, price evaluations, choices, and purchases. This research includes longitudinal surveys, interviews, and controlled experiments, both natural and in the laboratory. The present article starts with an overview of this research after which it more specifically focuses on research showing an influence of the nominal value, as expressed in different currencies, on price evaluations and consumer choice. For most countries, the transition to the euro led to a lower nominal value currency. A bias known as the “euro illusion” has been documented such that the subjective value of money is influenced in the direction of the nominal value (i.e., in most countries prices and salaries seem smaller when expressed in euros than in the old domestic currency). Although the term was coined in connection with the euro changeover, the nominal representation of a currency has been shown to influence the subjective value of money in unfamiliar currencies other than the euro. Thus, tourists travelling abroad may frequently be subject to such an illusion. Different mechanisms have been proposed to account for the euro illusion. One is the numerosity heuristic and another the anchoring-and-adjustment heuristic in conjunction with biased conversion strategies. The size of the euro illusion is influenced by trade-offs between accuracy and effort. Consistent with this hypothesis, task importance, time constraints, familiarity with the conversion strategy, complexity of the conversion strategy, mood, and attitude towards the country or the currency all influence the size of the euro illusion. 相似文献

This paper raises the question of how ethical issues arising out of social inequities involving international business in
developing countries can be represented, and articulates a conceptual framework that identifies and maps four different approaches
to representing or making sense of such issues. A fieldwork-based case study on the child labor issue in Pakistan’s soccer
ball industry illustrates the argument that representational practices do matter, and that when representational approaches
go awry, they end up savaging the well-being of the poor in the developing world.
