日本对华直接投资影响因素研究

本文借助于计量经济模型,以1985-2002年的统计数据为基础,对日本对华直接投资的决定性因素进行实证分析。结果表明,日本对华直接投资的主要影响因素包括中国市场容量、中日双边贸易、实际汇率和中日实际工资差异。通过对模型中各变量的比较和归纳,日本对华直接投资动机整体上可以综合为两个方面:一是日本的对外直接投资作为贸易主导型对外直接投资,以扩张本国的边际产业为直接目的;二是中国巨大的市场是吸引日本跨国公司对华直接投资的重要原因。     

人力资源管理系统形成影响因素的实证研究

在战略人力管理研究中,一直强调人力资源管理系统形态的形成需要和企业外部环境、企业特征和竞争战略保持匹配。在此基础上,文章建立了企业人力资源管理系统形成的影响因素模型,提出研究假设,并选取133家企业对假设进行了检验。研究发现,外部环境、企业规模对人力资源管理系统形成具有显著的影响,而人力资源管理经理是否专任和竞争战略并没有对企业人力资源管理系统形成产生显著的影响。最后,在对研究结论进行讨论的基础上,分析了研究的局限性并提出未来研究建议。     

HIGH‐ORDER SHORT‐TIME EXPANSIONS FOR ATM OPTION PRICES OF EXPONENTIAL LÉVY MODELS

The short‐time asymptotic behavior of option prices for a variety of models with jumps has received much attention in recent years. In this work, a novel second‐order approximation for at‐the‐money (ATM) option prices is derived for a large class of exponential Lévy models with or without Brownian component. The results hereafter shed new light on the connection between both the volatility of the continuous component and the jump parameters and the behavior of ATM option prices near expiration. In the presence of a Brownian component, the second‐order term, in time‐t, is of the form , with d₂ only depending on Y, the degree of jump activity, on σ, the volatility of the continuous component, and on an additional parameter controlling the intensity of the “small” jumps (regardless of their signs). This extends the well‐known result that the leading first‐order term is . In contrast, under a pure‐jump model, the dependence on Y and on the separate intensities of negative and positive small jumps are already reflected in the leading term, which is of the form . The second‐order term is shown to be of the form and, therefore, its order of decay turns out to be independent of Y. The asymptotic behavior of the corresponding Black–Scholes implied volatilities is also addressed. Our method of proof is based on an integral representation of the option price involving the tail probability of the log‐return process under the share measure and a suitable change of probability measure under which the pure‐jump component of the log‐return process becomes a Y‐stable process. Our approach is sufficiently general to cover a wide class of Lévy processes, which satisfy the latter property and whose Lévy density can be closely approximated by a stable density near the origin. Our numerical results show that the first‐order term typically exhibits rather poor performance and that the second‐order term can significantly improve the approximation's accuracy, particularly in the absence of a Brownian component.

Nonlinear Taylor rules in Central Eastern European countries

This study applies sequential panel selection method (SPSM), proposed by Chortareas and Kapetanios (2009) Chortareas, G., and G. Kapetanios. 2009. “Getting PPP Right: Identifying Mean-Reverting Real Exchange Rates in Panels.” Journal of Banking and Finance 33: 390–404.[Crossref], [Web of Science ®] , [Google Scholar], to investigate to test the validity of Taylor rules to assess the nonstationary properties of the convergence of the real exchange rates for 10 Central Eastern European countries. The SPSM can be used to decompose a panel of real exchange rate series into two groups: a group of stationary series and a group of nonstationary series. We identify the stationary processes in the panel and demonstrate that Taylor rules holds for 7 of the 10 countries studied. These results imply that the choices and effectiveness of the monetary policies in Central Eastern European economies are highly influenced by external factors originating from the United States. Additionally, our findings highlight that their real exchange rate convergence is a mean reversion toward equilibrium values of Taylor rules in a nonlinear manner.

产业销售起飞研究——以绿色农业产业为例

近年产业销售起飞机理成为产业组织和市场营销的研究热点。目前研究分支有:以产品销售扩散研究发展成的经典的Bass模型,但产品销售起飞本质上是个二分事件,所以扩散流派并没很好倡导和揭示起飞机理;Golder等人不仅提出起飞概念,而且在研究方法上借用生存分析等技术,并取得重大进展。采用"起飞阈值"法对绿色农业产业销售时机进行实证分析,结果表明绿色农业产业在2002年实现产业起飞。

Assessing Gender Differences in Computer Professionals’ Self-Regulatory Efficacy Concerning Information Privacy Practices

Concerns with improper collection and usage of personal information by businesses or governments have been seen as critical to the success of the emerging electronic commerce. In this regard, computer professionals have the oversight responsibility for information privacy because they have the most extensive knowledge of their organization’s systems and programs, as well as an intimate understanding of the data. Thus, the competence of these professionals in ensuring sound practice of information privacy is of great importance to both researchers and practitioners. This research addresses the question of whether male computer professionals differ from their female counterparts in their self-regulatory efficacy to protect personal information privacy. A total of 103 male and 65 female subjects surveyed in Taiwan responded to a 10-item questionnaire that includes three measures: protection (protecting privacy information), non-distribution (not distributing privacy information to others), and non-acquisition (not acquiring privacy information). The findings show (1) significant gender differences exist in the subjects’ overall self-regulatory efficacy for information privacy, and, in particular, (2) that female subjects in this study exhibited a higher level of self-regulatory efficacy than males for the protection and non-acquisition of personal privacy information. The identification of the factorial structure of the self-regulatory efficacy concerning information privacy may contribute to future research directed to examining the links between privacy efficacy and psychological variables, such as ethical attitude, ethical intention, and self-esteem. Studies can also be extended to investigate how different cultural practices of morality and computer use in men and women may shape the different development patterns of privacy self-efficacy. Understanding the different cultural practices may then shed light on the social sources of privacy competence and the appropriate remedies that can be provided to improve the situation.
