金融危机对我国养老保险的长期影响研究

08年开始的金融危机席卷全球,中国同样也深受其害。此次金融危机大约导致世界各种养老资产损失了5.5亿美元,而我国养老基金的直接损失大约为370亿。但是在金融危机逐渐弱化时,其对我国养老保险体系的长期影响逐渐显露出来,同时由于在金融危机期间政府采取了大量强有力的货币和财政政策,其对养老保险的影响也不能忽视。这些长期影响对我国养老保险体系的冲击是巨大的,必要加以重视。本文着重就金融危机对我国养老保险的长期影响进行分析,并在此基础上提出一些养老体系改革的政策建议。     

美国反倾销贸易保护效应的实证分析

通过建立美国各年向各涉案国家的进口额与反倾销申诉、反倾销措施及相关影响因素的回归模型,考察了1995-2008年美国发起的反倾销申诉和采取的反倾销措施对所有57个涉案国家和地区进口的影响.运用广义矩法对最小二乘估计的结果进行修正发现,虽然美国当期的进口主要由历史进口因素决定,但其反倾销申诉与措施会造成当期进口总额的显著下降,下降比例分别达到7.198%和5.890%,美国反倾销保护效应使美国年均进口额下降近1757亿美元,中国每年向美国的出口额减少超过127亿美元.     

Market orientation, guanxi, and business performance

The purpose of this research is to investigate the role of guanxi in the relation between market orientation (MO) and business performance (financial and strategic). In this study, based on prior findings, we have proposed that an interaction between MO and business guanxi is likely to be positively related to both financial and strategic performance. The interaction between MO and political guanxi is proposed to be negatively associated with financial and strategic performance. In this study we focus on the competitor orientation and interfunctional coordination of the MO components. Our findings advance the existing guanxi and MO-performance literature by revealing that; (a) business guanxi has both positive and negative effects on business performance (financial and strategic), (b) political guanxi has both positive and negative moderation effect on financial performance and a negative influence on strategic performance, (c) the alignment of guanxi and MO can be extended to the MO competitor and interfunctional coordination components, and (d) a proper match between guanxi and the MO elements is important. The outcomes of this study have implications for marketing managers and research concerning MO, guanxi, and business performance.     

‘Mainline’ telecommunications infrastructure, levels of development and economic growth: Evidence from a panel of developing countries

This paper assesses the growth impact of telecommunications infrastructure investment in developing countries by subjecting country-specific data on mainline tele-density and per capita growth to a Granger causality test within a panel cointegration framework. The results suggest that growth effects vary widely across country groupings reflecting different levels of development. Mainline tele-density and per capita growth strongly reinforce each other for countries that are relatively less developed. The reinforcement effect is even stronger for emerging countries that can be identified by their higher than average growth rates. In contrast, there is, at best, weak evidence of bi-directional causal links between the two variables for countries that are relatively more developed. These differences in the mainline tele-density and per capita growth relationships suggest that investment in telecommunications infrastructure, with its potential to generate high growth return, may serve as the critical tool for driving the growth and development process forward in the less developed countries.

The price stabilization effects of the EU entry price scheme for fruit and vegetables

The article assesses the stabilization effects of the EU import regime for fresh fruit and vegetables based on the entry price system (EPS). The analysis is carried out on the EU prices of tomatoes and lemons and those of imports from some of the main competing countries on the EU domestic markets: Morocco, Argentina, and Turkey. It is based on the estimation of a threshold vector autoregressive econometric model that is shown capable of taking the workings of the import regime into account. The model shows that prices behave differently when import prices are above/below the trigger entry price. This article allowed to highlight the cases for which the isolation effect of EPS seems reached and the resulting stabilization effects.     

Extension services,product quality and yields: the case of grapes in Argentina

This article studies the impact of publicly subsidized agricultural extension services on yields and product quality. We use panel data from grape producers in Mendoza, Argentina to estimate the impacts of farmer trainings. We find a negative overall impact on yields and evidence of a positive average impact on the adoption of higher‐quality grape varieties. By analyzing the dynamic pattern of the estimated effects, we find evidence of a temporary decrease in yields suggesting the existence of an adjustment process following the introduction of higher‐quality grapes. The overall negative effect on yield is driven by a sharp drop in the year of participation. This fades after year one, and two to three years after treatment we observe increases in higher‐quality grape production. Findings reinforce the importance of temporal dimension of extension services.

次贷危机改变了世界资本市场的风险格局吗?——基于Copula函数的协同效应检验

选取了世界上12个主要股票市场指数,采用Copula函数对次贷危机发生前、危机过程中、危机过后三个阶段国际资本市场风险的协同效应进行了测度,实证结论显示三个阶段世界资本市场间的风险协同性特征出现了明显变化,呈现出逐渐变弱的趋势,只有欧洲国家和巴西的资本市场与美国的资本市场仍保持较强的协同性特征。这意味着次贷危机改变了世界资本市场固有的风险格局,全球资本市场的一体化进程出现了放缓迹象。     

公司社会绩效理论与经验研究评述

上世纪70年代以来,公司社会绩效概念的提出将一种模糊、存在泛化倾向的社会责任思潮与企业战略实践紧密结合在了一起,为人们界定和评估公司社会责任提供了一个日趋简明一致的模型。与此相应,西方学术界围绕公司社会绩效开展了广泛了理论和经验研究。文章对公司社会绩效的理论模式、测量方法、决定因素和财务效应等四个基本问题的研究现状进行了综述和评价,指出了当前研究的不足及这一研究领域进一步发展的方向。
