Management and Business Research on Commercial Diplomacy: Examining Trends and Themes

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.     

约束稀疏脉冲反演在GX气田开发中的应用研究

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。     

European and Asian resistance to the use of the American case method in management training: possible cultural and systemic incongruencies

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.     

HEDGING STRATEGIES AND MINIMAL VARIANCE PORTFOLIOS FOR EUROPEAN AND EXOTIC OPTIONS IN A LÉVY MARKET

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.     

论道德效力及其表征

道德效力不仅仅是道德规范的影响力,而是道德价值体系整体的效力,是道德价值体系本身所具有的能实现一定社会目标、达到某种社会效果的力量。它不仅是一个量的概念,因受各种因素的影响而在程度上有所不同,而且在性质上也有善与恶的区分。相对于法律效力,道德效力有其独有的特性。其外在表征主要体现在求善的执着、个体的自律和他律、社会秩序的良好三个方面。     

The Relations between Minimal Martingale Measure and Minimal Entropy Martingale Measure

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.     

Distributions slanted to the right

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.     

Supplements and Complements to the Current Employee Representation System in the United States

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.     

The “Euro Illusion”: Illusion or Fact?

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.     

Representational Approaches Matter

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.
