城乡居民收入差距对居民消费影响的实证分析

回归分析证明了改革开放以来城乡居民收入差距过大导致整个消费水平越来越低,增加城市居民的收入不能提高我国居民的整体消费水平;城镇居民收入较高,相对于农村居民来说边际消费倾向要低于农村居民的边际消费倾向,如果能增加农村居民的收入,则会提高全国的消费总量及转变农村的消费结构。     

我国外汇储备投资的战略性目标及其实施

国家外汇投资公司的筹备成立标志着我国外汇储备管理模式的根本变化,文章认为外汇储备投资除满足收益性和缓解国内流动性过剩的使命外,应重点保障我国资源需求的战略目标;资源战略储备的形式除实物储备外,还可以直接购买或参股资源矿藏、购买资源类企业的股票以及通过国际期货市场进行运作.     

Macroeconomic factors and antidumping filings: evidence from four countries

This paper examines the relationship between antidumping filings and macroeconomic factors. Real exchange rate fluctuations affect the two criteria for dumping in opposite ways, making the overall effect on filings ambiguous in theory. Examining the filing patterns of the four major users of AD law during the 1980-98 period we find that real exchange rates and domestic real GDP growth both have statistically significant impacts on filings. Bilateral filing data indicate that a one-standard deviation real appreciation of the domestic currency increases filings by 33%. We also find one-standard deviation fall in domestic real GDP increases filings by 23%.

Why do buyers share knowledge with suppliers in new product development? current and alternative supplier antecedents

Purpose: Interfirm knowledge sharing has been well recognized to activate the performance and competitiveness improvement of the firms. Previous research has discussed the impacts of current suppliers on buyer–supplier knowledge sharing, but does not explain how this influence occurs. This study aims to disclose the mechanism by which both current and competing suppliers impact buyer–supplier knowledge sharing in buyers’ new product development activities.

Methodology/approach: This study proposed a conceptual model based on relational exchange theory and developed eight hypotheses. Questionnaire survey was used to collect empirical data from R&D staff of Taiwanese electronics firms. This study distributed 1,475 questionnaires and received 246 eligible questionnaires. Structural equation modeling was used to test and verify appropriateness of the proposed model.

Findings: The findings show that current supplier asset specificity positively and directly influences buyer–supplier knowledge sharing in new product development. The current supplier asset specificity also has indirect positive influence on buyer–supplier knowledge sharing in new product development via the mediating effects of buyer trust, satisfaction, and commitment. However, the attractiveness of alternative suppliers only indirectly and negatively affects buyer–supplier knowledge sharing via the mediating effects of buyer trust, satisfaction, and commitment.

Research limitations/implications: This study surveyed the firms in Taiwanese electronics industry. Nevertheless, new product development activities are executed by electronics firms in numerous countries and firms in various industries. For validating the generalization of this study’s results, future research can investigate firms in other industries and countries to verify the proposed model and hypotheses.

Practical implications: Current suppliers’ asset specificity is found to exert more influence on buyer–supplier knowledge sharing than alternative attractiveness. The findings imply that current suppliers should focus on investing specific assets for buyers other than stress the attractiveness and threat of competing suppliers.

Originality/value/contribution: This study initiates to approach the antecedents and influence mechanism of current buyer–supplier knowledge sharing via both perspectives of current and competing suppliers.     

Bilateral Opportunism in Buyer–supplier Partnerships

ABSTRACT

Purpose

Literature analyzes interorganizational relationships mostly from a relational perspective by emphasizing partnerships’ positive aspects. Yet business reality is often less romantic and more opportunistic. Especially within the automotive industry opportunistic behaviors often cause extreme reactions in both partners, resulting in poisoned relationships. This study examines the effects of bilateral opportunism between buyers and suppliers on both partners’ relationship induced financial performance, using an automotive industrial setting of new product development (NPD) partnerships. Furthermore, we evaluate the “opportunistic fit” between both partners to assess whether partnerships are characterized by opportunistic parity or unilateral domination.     

中美贸易顺差与人民币汇率关系的实证分析

针对中美贸易顺差与人民币汇率关系的问题,本文通过协整分析和Granger因果检验发现,人民币升值在短期难以对中美贸易顺差产生调节作用,从长期影响而言,人民币升值的影响作用也不大。此外,中美贸易顺差在短期还是主要取决于当前贸易收支的现实情况,而中长期则在很大程度上受到美国经济波动的影响。因此,人民币升值不会缓解美国巨大的贸易逆差,而且即使美国贸易收支出现改善也不会对美国经济发展产生显著的正面影响。
