The purpose of the present research is the study of the association amidst the practices of electronic procurement and its impact on supply chain performance. We analyzed four prime practices of e-procurement that known as electronic design, electronic sourcing, electronic negotiation, and electronic evaluation. Data was collected from 239 respondents doing jobs related to supply chain management using the Likert scale Questionnaire that was adopted from (Chang, Tsai, & Hsu, 2013) The data was analyzed using Structural Equation Modeling as well as Confirmatory Factor analysis. The results suggested that electronic design and electronic evaluation shown a positive and significant impact on supply chain performance whereas, electronic negotiation and electronic sourcing didn’t show a significant impact on supply chain performance. Hence, the findings imply that compare to electronic sourcing and electronic negotiation, electronic design, and electronic evaluation has more effect on supply chain performance. The administration must focus more on electronic design and electronic evaluation than electronic sourcing and electronic negotiation. Furthermore, the study advocates integration among supply chain members is equally important as to focus on joint learning practice because it leads to augment the supply chain performance. In addition, the study advocates that electronic procurement is at the side of the input of the supply chain system, therefore, it is more valuable for the industry to develop an innovative and effective process that satisfies all the needs of the organizational supply chain.
本研究的目的是研究电子采购实践中的关联及其对供应链绩效的影响。我们分析了电子采购的四种主要实践,即电子设计、电子采购、电子谈判和电子评估。使用(Chang, Tsai, & Hsu, 2013)采用的李克特量表问卷,从239名从事供应链管理相关工作的受访者中收集数据,使用结构方程模型和验证性因子分析对数据进行分析。结果表明,电子设计和电子评估对供应链绩效有显著正向影响,而电子谈判和电子采购对供应链绩效无显著影响。因此,研究结果表明,与电子采购和电子谈判相比,电子设计和电子评估对供应链绩效的影响更大。政府必须更多地关注电子设计和电子评估,而不是电子采购和电子谈判。此外,该研究主张供应链成员之间的整合与关注联合学习实践同样重要,因为它可以提高供应链绩效。此外,本研究主张电子采购处于供应链系统的输入端,因此,开发一种满足组织供应链所有需求的创新而有效的流程对行业来说更有价值。

English Abstract: The objective of this paper is to demonstrate that Reverse logistics (Reverse Logistics or Return Logistics) in the Agrifood Industries (IAA) can contribute to the sustainable development of Cameroon. Reverse logistics in the IAA is at the center of supplying companies with non-biodegradable raw materials in the Supply Chain. The return delivery of the companies by these flows makes it possible to produce and quickly create incomes and consequently, Cameroon draws there from economic growth, improving the well-being of the current populations while preserving that of the future generations. This demonstration is made from an analysis of the long-term impact of these flows on businesses. Empirical results show that Reverse Logistics in LPNs does not contribute enough to sustainable development because of the lack of environmental governance. In other words, a notorious laxity in respecting laws, regulations and standards in public institutions in charge of the environment.
摘要:本次交流的目的是证明农业食品工业(IAA)的逆向物流(逆向物流)可以为喀麦隆的可持续发展做出贡献。iaa中的逆向物流是企业供应链中不可生物降解原材料供应的核心。通过这些流动的企业回流可以快速生产和创造收入,从而使喀麦隆受益于经济增长,改善当代人的福祉,同时保护子孙后代的福祉。这是通过分析这些流动对企业的长期影响来证明的。经验结果表明,由于缺乏环境治理,aai中的逆向物流对可持续发展的贡献不足。换句话说,负责环境的公共机构在遵守法律、法规和标准方面明显松懈。英文摘要:本文的目的是证明农业食品工业的逆向物流(逆向物流或退货物流)可以为喀麦隆的可持续发展做出贡献。IAA的逆向物流是供应链中不可生物降解原材料供应公司的核心。通过这些流动的公司的回报使产生和迅速创造收入成为可能,因此,喀麦隆从经济增长中获得了收入,改善了当代人的福祉,同时保护了后代的福祉。这个演示是基于对这些流动对业务的长期影响的分析。经验结果表明,由于缺乏环境治理,LPNs的逆向物流对可持续发展的贡献不足。换句话说,负责环境的公共机构在遵守法律、条例和标准方面表现出明显的松懈。

Climate Change and Adaptation in Global Supply-Chain Networks 全球供应链网络中的气候变化与适应
Pub Date : 2019-10-25 DOI: 10.2139/ssrn.3475416
Nora M. C. Pankratz, Christopher M. Schiller
This paper examines how firms adapt to climate-change risks resulting from their supply-chain networks. Combining a large sample of global supplier-customer relationships with granular data on local temperatures and flooding incidents, we first document that the occurrence of climate shocks at affected supplier firms has both a large direct and indirect negative effect on earnings and revenues of suppliers and their customers. Second, we show that customers are 10% to 20% more likely to terminate existing supplier-relationships when realized climate shocks at the supplier firms exceed ex-ante expected climate shocks. Further, customers subsequently switch to suppliers with lower heatwave and flooding exposure. Our results indicate that climate change affects the formation of global production networks.
本文考察了企业如何适应其供应链网络带来的气候变化风险。结合全球供应商-客户关系的大样本与当地温度和洪水事件的细粒度数据,我们首先证明,在受影响的供应商公司中,气候冲击的发生对供应商及其客户的利润和收入都有很大的直接和间接的负面影响。其次,我们表明,当供应商公司实现的气候冲击超过事先预期的气候冲击时,客户终止现有供应商关系的可能性增加10%至20%。此外,客户随后会转向热浪和洪水风险较低的供应商。研究结果表明,气候变化影响全球生产网络的形成。

Trade Facilitation, Digital Transformation and the Emergence of Global Trade Platforms 贸易便利化、数字化转型与全球贸易平台的出现
Pub Date : 2019-06-30 DOI: 10.2139/ssrn.3412370

The World Trade Organization Trade Facilitation Agreement that entered into force in 2017 encourages the migration of trade processes from paper to electronic form and the modernisation of trade management systems. The foundations for current progress in trade facilitation were laid during decades of work by the World Customs Organization and other standard setting bodies to promote the use of standards in trade processes. Trade facilitation efforts are taking place within a broader push toward the digital transformation of business generally, and the growing importance of platforms as a business model and network governance mechanism. There is a risk that collective action problems arising within domestic and global markets will fragment the emerging digital architecture of global markets into many separate “national single window” systems. Platforms succeed by discovering how to organize cross-subsidies among different groups of stakeholders. If a global trade platform operator were to emerge, that might mitigate the risk of fragmentation of the emerging global trade architecture but give rise to different risks.
2017年生效的《世界贸易组织贸易便利化协定》鼓励将贸易流程从纸质形式转向电子形式,并实现贸易管理系统的现代化。目前在贸易便利化方面取得进展的基础是世界海关组织和其他标准制定机构几十年来为促进在贸易过程中使用标准而进行的工作所奠定的。贸易便利化的努力是在更广泛的推动商业数字化转型的背景下进行的,平台作为一种商业模式和网络治理机制的重要性日益增加。有一种风险是,国内和全球市场内部出现的集体行动问题,将把全球市场新兴的数字架构分裂成许多独立的“国家单一窗口”系统。平台的成功在于发现了如何在不同的利益相关者群体之间组织交叉补贴。如果出现一个全球贸易平台运营商,这可能会减轻新兴全球贸易架构碎片化的风险,但也会带来不同的风险。

You’ll Never Walk Alone: Why We Need a Supply Chain Practice View on Digital Procurement 你永远不会独行:为什么我们需要数字化采购的供应链实践观点
Pub Date : 2019-06-20 DOI: 10.2139/ssrn.3423299

Abstract This paper conceptualizes digital procurement readiness as a dyadic construct and introduces the supply chain practice view (SCPV) as a theoretical lens that can help guide future research on digital procurement. We build on a literature review and on dyadic, explanatory case studies to provide a nuanced understanding of how the digital readiness of supply chain partners—on both sides of the dyad—needs to co-evolve for the implementation of digital procurement practices. Specifically, we outline how the SCPV can serve as both a holistic and a supply chain-specific framework for future research on the following: 1) the antecedents that help explain why supply chain partners adopt inter-organizational digital procurement practices, and 2) the relational performance outcomes derived from their use. For managers, this study implies the need to explicitly consider interactions with and influences of supply chain partners in their quest to rapidly and effectively digitalize procurement.
摘要本文将数字化采购准备度定义为一个二元结构,并引入供应链实践视角(SCPV)作为一个理论视角,可以帮助指导未来数字化采购研究。我们在文献综述和二元、解释性案例研究的基础上,对供应链合作伙伴(二元双方)的数字化准备情况如何需要共同发展以实施数字化采购实践提供了细致入微的理解。具体来说,我们概述了SCPV如何既可以作为一个整体框架,也可以作为一个供应链特定框架,用于以下方面的未来研究:1)有助于解释为什么供应链合作伙伴采用组织间数字采购实践的前因,以及2)使用它们产生的关系绩效结果。对于管理者来说,这项研究表明,在寻求快速有效的数字化采购时,需要明确考虑与供应链合作伙伴的互动和影响。

Public and Reputational Sanctions: The Case of Cartels 公众和声誉制裁:卡特尔案例
Pub Date : 2019-01-14 DOI: 10.2139/ssrn.3315305
Franco Mariuzzo, Peter L. Ormosi, Zherou Majied
In this article, we revive an old debate in the law and economics literature: the relative role of public and private (market-based) sanctions in deterring misconduct. We offer a novel framework, which accounts for public sanctions and a more direct measure of private sanctions, harnessing recent developments in opinion mining. We use the intensity and the sentiment of media exposure of misconduct as a measure of reputational effect and thus an approximation of the private sanction. As a demonstration, we combine event study techniques, sentiment analysis, and classic econometrics on a sample of 339 listed cartel member firms, prosecuted by the European Commission between 1992 and 2015. We offer evidence that in the context of cartels, public and private sanctions act as substitutes.
在本文中,我们将重新讨论法律和经济学文献中的一个老问题:公共和私人(基于市场的)制裁在阻止不当行为方面的相对作用。我们提出了一个新的框架,它考虑到公共制裁和更直接的私人制裁措施,利用舆论挖掘方面的最新发展。我们使用媒体曝光不当行为的强度和情绪作为声誉影响的衡量标准,从而近似于私人制裁。作为实证,我们将事件研究技术、情绪分析和经典计量经济学结合起来,对1992年至2015年间被欧盟委员会起诉的339家上市卡特尔成员公司进行了样本分析。我们提供的证据表明,在卡特尔的背景下,公共和私人制裁起替代作用。

The Factors Impacting the Success of Supply Chain Management in the Construction Industry of Pakistan 影响巴基斯坦建筑业供应链管理成功的因素
Pub Date : 2019-01-01 DOI: 10.2139/ssrn.3382200
Muhammad Sher Gabol, D. Siddiqui
Purpose: Present study is conducted to investigate the impact of top management commitment on supply chain responsiveness with mediating role of organizational factors, mutual understanding, and flow of information, relationship and decision making.

Design/Methodology/Approach: A sample of 120 respondents is collected from various construction projects. In survey process adopted questionnaire is used to investigate the hypotheses. The study used descriptive statistics, structural equation modeling, factor analysis, reliability analysis, and correlation analysis.

Findings: Based on SEM and CFA it is supported that responsiveness of supply chain is directly and significantly affected by top management commitment and indirectly affected by mediators including information sharing and mutual trust. Yet results did not support indirect effect of organizational factors and relationship & decision making. Results of the study implies that the effectiveness of supply chain could be quantified and adopted by industry professionals for comparing the effectiveness of SCM for a bench marking purpose.

Forward Trading and Collusion in Supply Functions 期货交易与供给函数中的共谋
Pub Date : 2019-01-01 DOI: 10.2139/ssrn.3336525
N. Wölfing
This paper studies the effect of forward contracts on the stability of collusion among firms, competing in supply functions on the spot market. A forward market can increase the range of discount factors which allow to sustain collusion. On the contrary, collusion is destabilised when a potential deviator sells a significant amount forward. Results do not depend on the type (financial or physical) of contract fulfilment and are robust to different levels of demand uncertainty. As a policy implication, the study finds that liquid and anonymous forward markets are incompatible with collusion.
本文研究了期货合约对现货市场上竞争供给职能的企业间合谋稳定性的影响。远期市场可以增加贴现因子的范围,从而维持勾结。相反,当一个潜在的偏差者大量远期卖出时,共谋就会不稳定。结果不依赖于合同履行的类型(财务或物理),并且对于不同水平的需求不确定性是稳健的。作为政策暗示,研究发现流动性和匿名远期市场与共谋是不相容的。

As a policy implication, the study finds that liquid and anonymous forward markets are incompatible with collusion.","PeriodicalId":12584,"journal":{"name":"Global Commodity Issues eJournal","volume":"51 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90807872","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Profit and Loss Distributions on a Market of Single Futures Contract 单一期货合约市场的盈亏分配
Pub Date : 2018-12-23 DOI: 10.2139/ssrn.3305964
V. Salov
Profit and loss distributions of trading strategies with position limits and transactions costs are divided on industry gain and traders interest and determined for a single futures contract. Open interest and volume are expressed for a multiset of strategies with constraints. These strategies are more complicated than Dyck and Motzkin paths. A generating polynomial for the number of integer partitions with labeled parts in a multiset and two algorithms are presented. Weibull, Gamma, Kumaraswamy distributions for sample statistics of skewness and excess kurtosis of tick volumes are discussed.
有仓位限制和交易成本的交易策略的盈亏分配根据行业收益和交易者利益进行划分,并为单一期货合约确定。对一组有约束的策略,用未平仓量和未平仓量来表示。这些策略比Dyck和Motzkin路径更复杂。给出了多集中带标记部分的整数分区数目的生成多项式和两种算法。讨论了蜱虫体积偏度和过量峰度样本统计的Weibull、Gamma、Kumaraswamy分布。
