FDI、要素成本与东道国产业发展

论题拓展了James R Markusen（1997）的基本模型，重点纳入外商直接投资进入东道国对其要素市场的影响，分析了FDI与东道国产业的关联效应以及在要素市场的竞争效应对东道国产业发展的影响。外商直接投资将通过关联效应和要素市场的竞争对东道国产业发展产生一个动态二阶段影响过程：在初始阶段外商直接投资的进入将引导东道国发展最终消费品产业，从而促进产业结构变动；但在东道国产业发展到一定阶段后外商直接投资与东道国产业在要素市场的竞争加剧将阻碍东道国产业发展。     

State‐led transnationalism and migration: reaching out to the Argentine community in Spain

Abstract This article focuses on when and how states develop transnational policies. It presents a case study of a relatively small emigrant community, whose departure was not simply caused by poverty or crisis, but most recently by an economic and political debacle that questioned people's values and expectations. I focus on the state side of the equation and identify a shift in Argentina's policy after 2003, though also show how such policies came out of a long history of state intervention in population and migration and are now related to human rights concerns and the unfinished process of democratic consolidation. I argue that the state initiates political transnationalism, not migrants, and highlight the importance of some relatively unexplored factors in the understanding of the motivation, intensity and impact of the state's involvement, such as the characteristics of the emigrant community, the existence of specific political projects, the role of some domestic actors and processes, and the nature of international agreements.     

基于EGARCH模型的我国股市信息对称性研究

利用过去17年我国上证综合指数的历史数据,根据股票市场大的波动周期分五阶段经过EGARCH(1,1)模型估计,以验证市场对信息冲出的反映情况.研究结果表明:中国股市存在很大的波动性,尚未达到弱有效性;存在正负杠杆效应交替出现的现象,表现出信息不对称性,但是这种不对称性在明显减小.     

可转换公司债券的杠杆效应研究

对于运用可转换公司债券进行理财的公司而言,充分了解可转换公司债券的杠杆效应是极其必要的。可转换公司债券在给发行公司带来财务杠杆效应的同时,也对发行公司的每股赢余产生稀释效应,但这一稀释效应要比股权融资对每股收益的影响低;可转换公司债券的价值与其股票的价值虽具有联动效应,但其间的关系较为复杂;可转换公司债券在为发行公司提供预防被收购的有利武器的同时,也为其持有者提供了间接购买股票的手段;可转换公司债券可缓解股东与债权人之间的代理问题、管理层和股东之间的利益冲突,有利于公司治理的结构完善。     

A bayesian estimator for the dependence function of a bivariate extreme‐value distribution

Any continuous bivariate distribution can be expressed in terms of its margins and a unique copula. In the case of extreme‐value distributions, the copula is characterized by a dependence function while each margin depends on three parameters. The authors propose a Bayesian approach for the simultaneous estimation of the dependence function and the parameters defining the margins. They describe a nonparametric model for the dependence function and a reversible jump Markov chain Monte Carlo algorithm for the computation of the Bayesian estimator. They show through simulations that their estimator has a smaller mean integrated squared error than classical nonparametric estimators, especially in small samples. They illustrate their approach on a hydrological data set.     

轻声的作用与语音修饰

作为一种重要的语音现象，仅从可区别词义及词性来解释轻声的存在因由是不能令人信服的。轻声在语流中的语音修饰作用所带给我们的审美感受使得它的存在有理有据。     

Block external bootstrap in partially linear models with nonstationary strong mixing error terms

The authors extend the block external bootstrap to partially linear regression models with strongly mixing, nonstationary error terms. In addition to providing an approximate distribution for the semiparametric least square estimator of the parametric component, they propose a consistent estimator of the co‐variance matrix of this estimator.     

企业资本结构与产品市场战略

直到20世纪80年代,企业资本结构对产品市场竞争的影响才引起经济学家的广泛关注.对于这一问题的研究,存在着两种截然不同的理论结论:一种观点认为企业债务水平的提高会使其在产品市场竞争中更为强硬,增强其竞争力;另一种观点则恰好相反.事实上,企业的融资决策具有两种不同的间接效应:代理效应和策略效应.企业的融资决策在其代理效应和策略效应的平衡点达到最优.企业的融资决策与其产品市场策略之间的关系依赖于代理问题的性质、不确定性的来源及产品市场的特征等因素,企业的最优资本结构应该随这些因素的变化而变化.     

If you look like me,I'll talk to you: a preliminary study of ethnic identity and inter‐ethnic interaction among women in Singapore

In Singapore, government policy is for equal but separate development of the four major ethnic groups—Chinese, Malay, Indian and other. In this study, I attempt to gain some preliminary views of how strongly women identify with their own ethnic group and how freely they are prepared to interact with people from other ethnic groups in non‐work‐related situations. I confine my study to females for two reasons. One is that traditional ethnic dress is common among females in Singapore but much rarer among men, and this makes a strong non‐verbal statement of identity. The second reason is to avoid differences between males and females, which I did not wish to pursue within the limits of this exploratory study. The findings of my pilot investigation indicate that intra‐ethnic spontaneous interaction is more likely to occur among women who display a strong national identity. Moreover, younger women, who were exposed during their school years to the government's recent drive to nurture ethnic and cultural differences, are less open to inter‐ethnic interaction than are women in their 30s and older, who grew up when the government drive was towards creating one common national identity for the people of Singapore.     

我国产业间波及效应的探讨

从理论上来说,某一产业的变化会引起其它产业间的连锁反映。产业间的波及效应可以通过投入系数表来加以分析。通过实证分析,研究我国产业间波及效应的强弱,可以为国家制定产业政策、优化产业结构提供依据。
