THE ROLE OF PURCHASING IN CORPORATE SOCIAL RESPONSIBILITY: A STRUCTURAL EQUATION ANALYSIS

Researchers in the field of corporate social responsibility (CSR) have examined a broad array of activities including environmental management, ethical issues, the advancement of a diverse workplace, safety, human rights, philanthropic donations, and community involvement. Yet despite over 30 years of inquiry in this field, there has been no holistic, empirical investigation of the particular dimensions or sets of activities that are encompassed by CSR and the relationship between ethics and CSR. In the purchasing and supply management literature, similar sets of activities have been investigated, but generally as separate, standalone streams of research with little recognition of their potential inter‐relatedness. The current study empirically identified the dimensions of purchasing's involvement in CSR and applied the label purchasing social responsibility (PSR).

Electronic marketplaces and supply chain relationships

Electronic marketplaces and supply chain management (SCM) are two notions, which have attracted much attention among both academicians and practitioners during the last 5 years. However, the discussion of the relationship between the two notions has been limited and fragmented. In this paper, we will present a critical summary of the discussion of Internet-driven electronic marketplaces (IEMPs) based on an extensive literature review. Then, we will discuss the interrelation between IEMP and SCM from a procurement portfolio perspective. Our proposition is that different types of buyer-supplier relationships require different types of IEMPs. We propose a relationship/IEMP-grid that should help to identify the right selection strategy for IEMP in various procurement situations. Finally, we present proposals for future research within this area.     

我国货币流通速度的分析

本文首先把GDP与M2的比值定义为货币流通速度,计算出1993～2005年我国货币流通速度,该数据表明我国货币流通速度有减慢的趋势,这反映了我国体制上的深层次问题。其次,用带有动量项和自适应学习率的BP神经网络预测出2006～2007年我国GDP和货币流通速度,从而推算出2006年至2007年我国广义货币供应量(M2)分别是324542.6亿元和341568.6亿元左右,这对我国数量型货币政策的制定具有一定的参考价值。

SUPPLY CHAIN PARTNERSHIPS: MODEL VALIDATION AND IMPLEMENTATION

An important aspect of implementing supply chain management is the formation of appropriate linkages between members of the supply chain. While practitioners and academics have championed the value of partnerships for this purpose, the challenge is to find effective methods for developing the appropriate type of relationship. This paper describes a large‐scale validation of a previously developed model that can be used to structure business relationships. Implementation issues are documented and direction is provided for managers interested in using this tool for tailoring key relationships.     

Shaping beliefs in experimental markets for expert services: Guilt aversion and the impact of promises and money-burning options

In a credence goods game with an expert and a consumer, we study experimentally the impact of two devices that are predicted to induce consumer-friendly behavior if the expert has a propensity to feel guilty when he believes that he violates the consumerʼs payoff expectations: (i) an opportunity for the expert to make a non-binding promise; and (ii) an opportunity for the consumer to burn money. In belief-based guilt aversion theory the first opportunity shapes an expertʼs behavior if an appropriate promise is made and if it is expected to be believed by the consumer; by contrast, the second opportunity might change behavior even though this option is never used along the predicted path. Experimental results confirm the behavioral relevance of (i) but fail to confirm (ii).     

How stable is M2 money demand function in Japan?

The cointegrating property of the demand for money in Japan has been investigated by several researchers who have provided mixed results. None has investigated its stability. In this paper we employ the ARDL approach combined with CUSUM and CUSUMSQ tests to show that not only M2 is cointegrated with income and interest rate, but the estimated relation is stable.     

Are the markets for financial assets efficient? : Evidence for the USA, 1974–1988

The analysis in this paper addresses the efficient markets hypothesis as it pertains to the markets for financial assets. Both weak form efficiency and semistrong form efficiency are investigated for three different financial assets - common stocks, preferred stocks and government bonds. For these assets the markets are indicated to be weak form efficient based on monthly data covering the period January 1974 to June 1988. In the case of semistrong form efficiency, the financial assets markets are efficient with respect to the supply of money for the period after October 1979 but not before. This anomaly is attributed to the different procedures used by the Federal Open Market Committee between the two periods for controlling the growth rate of the money supply.     

我国经济中长期趋势及政策取向

从中长期经济增长趋势特征看,根据HP滤波方法刻画的潜在产出曲线,中国经济持续高增长的条件已经发生变化,潜在产出增长率在2006年达到阶段性历史高位后逐年下降。基于工业化、城镇化、区域协调发展等因素,以及高储蓄率对高投资率的支持,中期内我国投资增长仍将保持较强的惯性。然而,长期增长则取决于全要素生产率的提高。鉴于我国结构性问题突出,需要重视运用供给管理政策,加强薄弱环节建设。
