Hedging,Financing and Investment Decisions: A Simultaneous Equations Framework

We empirically investigate the interactions among hedging, financing, and investment decisions. We argue that the way in which hedging affects a firm's financing and investing decisions differs for firms with different growth opportunities. We find that high growth firms increase their investment, but not leverage, by hedging. However, we also find that firms with few investment opportunities use derivatives to increase their leverage.     

Foreign debt and economic growth

This paper empirically examines the relationship between government foreign debt and the growth rate of per capita GDP based on a total sample of 77 countries, as well as sub‐samples of various regions. Cross‐sectional estimates of the coefficient of foreign debt based on the total sample have a negative sign, but are not always statistically significant. Available data from African countries indicate that foreign debt and the growth rate of per capita GDP were negatively related at a high level of significance. For industrialized and Latin American sub‐samples, this relationship is negative but statistically insignificant. The sub‐sample Asian and other developing countries show a positive but insignificant relationship. JEL classification: F34, H6, O23.     

Dynamics of the federal funds target rate: a nonstationary discrete choice approach

We apply a discrete choice approach to model the empirical behaviour of the Federal Reserve in changing the federal funds target rate, the benchmark of short‐term market interest rates in the US. Our methods allow the explanatory variables to be nonstationary as well as stationary. This feature is particularly useful in the present application as many economic fundamentals that are monitored by the Fed and are believed to affect decisions to adjust interest rate targets display some nonstationarity over time. The chosen model successfully predicts the majority of the target rate changes during the time period considered (1994–2001) and helps to explain strings of similar intervention decisions by the Fed. Based on the model‐implied optimal interest rate, our findings suggest that there is a lag in the Fed's reaction to economic shocks during this period. Copyright © 2004 John Wiley & Sons, Ltd.

刍议虚拟财产的法律保护

随着网络,尤其是网络游戏的迅猛发展,虚拟财产的交易及其保护引发了是否要对其加以保护,如何进行保护,如何进行规范等一系列问题,在我国的司法实践中已经不得不开始面对这类纠纷的裁判,而在法律上有关虚拟财产的规则尚处于不确定的空白,给这类纠纷的解决带来了很大的障碍,基于此,进行虚拟财产特性、交易等等相关法律问题的研究,并在探讨其合法性的前提下,进一步论证虚拟财产的法律保护规则的建构具有十分重要的理论意义与现实意义。     

美投资银行的竞争优势及对内地投资银行业的冲击——基于波特钻石理论和动态企业能力论视角

在金融业全面对外开放的条件下,中国脆弱的投资银行业面临新一轮的挑战,被外国投资银行攻城掠地的场面是否会在中国继续上演?对此,波特的钻石理论提出了使一个国家具备产业竞争优势的六个因素,但真正使一个国家产业具备竞争优势却在于企业内部的组织学习和创新.美国投资银行业基于长期对生产要素的投资和积累形成了全球性的竞争优势,占据了投资银行高端业务并有进一步争夺中国投资银行业务的趋势.面对冲击,国内投资银行应立足自身优势,发展壮大自己,而政府也应在产业规制和健全宏观环境上下功夫.     

企业信息化过程中知识转移能力研究

考虑到企业信息化建设过程中知识转移的能力具有灰色性和模糊性的特点,传统的分析方法具有很大的局限性。本文采用基于信息熵权值的多层次灰色评价理论,对信息化过程中知识转移的能力的多级指标体系进行综合评判,为企业提供决策以及改进的依据,最后给出运用该方法的一个实例。该方法具有较强的实际应用价值。     

围绕“内卷化”的讨论——一次新的范式转型

对于同样的一种行为——妇女参加手工业劳动,在《华北的小农经济与社会变迁》一书中不被判断为内卷化的表现,而在《长江三角洲小农家庭与乡村发展》一书中则被判断为主要的内卷化表现之一,这不能不说是“内卷化”概念的混乱。
