Purchasing Competence: A Stakeholder‐Based Framework for Chief Purchasing Officers

A specific research stream within the purchasing and supply management literature focuses on the development of purchasing competence frameworks. We apply stakeholder theory and multiple methods of data collection to develop and confirm a hierarchy‐specific purchasing competence management framework for Chief Purchasing Officers and validate it using confirmatory factor analysis on empirical data from 124 multinational companies. The results reveal a significant relationship between Chief Purchasing Officers purchasing management competence and different purchasing performance measures confirming the appropriateness of stakeholder theory for such a competence framework.     

网上商品热销的影响因素探析——基于分位数回归的实证研究

本研究从网上销售的影响因素出发,采用搜索程序获取了淘宝网的4059个货架1周的销售数据,通过分位数回归方法对不同热门程度产品的价格、信誉、保障标记以及口碑的需求弹性进行了实证分析。研究结果表明,随着产品热门程度的提高,信誉的需求弹性不断增强,而价格、保障标记以及口碑的需求弹性却不断减弱。由此表明,产品的价格降低,保障标记级别和口碑的提升都能使销售趋于分散,而提高商家的信誉却能加速销售向热门产品集中,使得"热门更热"。     

Institutional Pressures and an Evolving Forest Carbon Market

It is estimated that 87 million acres of forestland in the United States (US) is managed by private industrial forestland owners (nearly 14% of the forestland nationwide). Private industrial forestland owners include forest product companies, Timber Investment Management Organizations (TIMOs) and Real Estate Investment Trusts (REITs). Current regulatory and voluntary carbon markets, as well as proposed national emission reduction legislation, in the US make provisions for substantial carbon offsets from domestic forestry projects. This research employs the theory of planned behavior by means of an online questionnaire in order to survey large industrial forestland owners (>30 000 acres) regarding intentions to manage forestland for carbon sequestration and trading. Quantitative results suggest that very few organizations (18%) were managing forestland for carbon values. Attitudes towards carbon sequestration and trading were significantly influenced by the managers' beliefs that emission reduction legislation would become law and that US forest carbon offsets can be used as a legitimate climate change mitigation tool. Qualitative results revealed that most organizations are taking a passive approach to carbon sequestration and trading until a suitable regulatory framework emerges and carbon prices provide the conditions for a sound investment. The researchers suggest that, given the size and scope of the climate change phenomenon as well as the multifaceted and unified mitigation strategy required to address it, the development of functional carbon markets will be an iterative process and may require a global carbon framework that reflects the globalized nature of the forest economy.

Determinants of Traditional Sustainability Reporting Versus Integrated Reporting. An Institutionalist Approach

The aim of this study is to analyze similarities and differences between companies with traditional sustainability reporting (TSR) and those that publish integrated reports. Based on institutional theory we identify potential determinants of integrated reporting (IR) and test their relevance empirically in a sample of 309 companies. Our analysis shows that IR companies are different from TSR companies with regard to several country‐level determinants. In particular, investor and employment protection laws, the intensity of market coordination and ownership concentration, the level of economic, environmental and social development, the degree of national corporate responsibility and the value system of the country of origin proved to be relevant. Based on these results, both implications for practice and future studies are derived. Copyright © 2011 John Wiley & Sons, Ltd and ERP Environment.     

If you,tourist, behave irrationally,I’ll find you!

When departures from rational behavior can potentially be expected, modeling should allow for their identification and their quantification. In this regard, prices in tourism might have effects that may not be as apparent as economic theory predicts. This article incorporates the sticker shock formulation into the mixed logit model without imposing consistency with consumer theory to accommodate any possible positive or negative price effects. By allowing the parameters of “price” and “sticker shock term” to take any value – negative or positive – we detect abnormal behaviors in the tourist demand: not only is the negative relationship between price and demand inverted for some people but also some tourists might be willing to accept higher-than-expected prices. The “non-well-behaved” groups' shares are estimated.
