Following the attacks of September 11th, public and private entities recognized a need to protect the global supply chain from terrorist disruption. In response to this need, the U.S. Government partnered with industry to create the Customs‐Trade Partnership Against Terrorism (C‐TPAT) program. This research investigates the public–private partnership (PPP) relational aspects of C‐TPAT. C‐TPAT encourages firms to voluntarily improve their security competence and that of their supply chain partners. We introduce the concept of relational security in the context of PPPs. We define relational security as all activities that establish, cultivate, and maintain successful security exchanges between parties. We establish C‐TPAT as one indicator of relational security by demonstrating its ability to establish, cultivate, and maintain successful security exchanges between parties. Results indicate certified firms outperform noncertified firms in security performance, firm performance, and resilience.  相似文献

【美国《福布斯》10月26日】中国经济全面向好 10月22日出炉的官方数据显示,中国3季度中国经济增速高达8.9%。这主要是得益于中央和地方政府启动了大批营建和基建项目,以及出口显著回暖。同挤牙膏式的美国经济刺激计划不同,中国政府将6000G美元经济刺激计划基本上一步落实到位,并且辅之以投放超过1万亿美元的信贷资金。与之形成鲜明反差的是,美国银行业却一直在积聚存款而且惜贷意愿浓厚。  相似文献

Substitution decisions have been examined from a variety of perspectives. The economics literature measures cross-price elasticity, operations research models optimal assortments, the psychology literature studies goals in conflict, and marketing research has examined substitution-in-use, brand switching, stockouts, and self-control. We integrate these perspectives into a common framework for understanding consumer substitution decisions; their specific drivers (availability of new alternatives, internal vs. external restrictions on choice); the moderating role of a consumer’s commitment to an initially desired alternative; and the affective, motivational, cognitive, and behavioral outcomes of substitution. We use this framework to recommend new avenues for research.  相似文献

The equivalence between multiportfolio time consistency of a dynamic multivariate risk measure and a supermartingale property is proven. Furthermore, the dual variables under which this set-valued supermartingale is a martingale are characterized as the worst-case dual variables in the dual representation of the risk measure. Examples of multivariate risk measures satisfying the supermartingale property are given. Crucial for obtaining the results are dual representations of scalarizations of set-valued dynamic risk measures, which are of independent interest in the fast growing literature on multivariate risks.  相似文献

The COVID-19 pandemic has reduced well-being and economic security on a number of dimensions, likely worsening mental health. In this paper, we assess how mental health in the US population has changed during the pandemic. We use three large, nationally representative survey sources to provide a picture of mental health prior to and during the pandemic. We find dramatic but broad-based declines in the level of mental health from pre-pandemic baseline measures across both people and places. Rates of poor mental health have jumped roughly 25 percentage points, from a base of roughly one-third. We document substantial disparities in mental health but show that the pandemic has generally preserved, rather than widened, these. Significant worsening in relative mental health among Hispanics and respondents aged 30 and older are exceptions. Consistent with an important role for pandemic-specific shocks, We find that income loss, food insecurity, COVID-19 infection or death in one's close circle, and personal health symptoms are all associated with substantially worse mental health. If anything, the decline in mental health is worsening as the pandemic wears on and is becoming less related to local COVID-19 case rates.  相似文献

Recent protectionist trends around the world have raised interest in newly enforced or increased tariffs and their effects on global supply chains. For firms sourcing globally, tariff introductions or increases significantly affect importing costs, which ultimately affect product costs. Such tariff changes may incentivize firms to adjust their supply base to mitigate these cost increases, thus altering the structure and complexity of firms' supply bases. In this paper, we first characterize the U.S. tariff landscape from 1997 to 2017. We then develop a conceptual model to explain how the severity and timing uncertainty of expected tariff increases influence a firm's speed of adapting to the changing tariff environment. Specifically, we explore firms' propensity to form or delete ties to suppliers, which influences supply base complexity. Moreover, we consider factors that moderate the relationship between severity, timing uncertainty, and supply base complexity, including a tariff's geographical scope, a firm's relative purchase spend, and supply risk. Our conceptual model offers both research and managerial implications.  相似文献

Research Summary : We advance the concept of organization–stakeholder fit (O–S fit) to explain cooperative behavior between an organization and its stakeholders. O–S fit describes the compatibility that exists between an organization and a stakeholder when their characteristics are well matched. We highlight two dimensions of O–S fit: value congruence, or the supplementary fit of organizational and stakeholder values, and strategic complementarity, or the complementary fit of strategic needs and resources. For each dimension, we detail the unique relational factors—including core elements of trust, predictability, attraction/exchange, and communication—that motivate cooperation. We then explicate the ways in which value congruence and strategic complementarity dynamically interrelate over time. Finally, we consider how organization‐stakeholder misfit may result in alternative relational behaviors, such as conflict or compromise. Managerial Summary : We develop a new way of thinking about the relationship between organizations and stakeholders. Recognizing that positive relationships require a degree of fit or compatibility, we argue that cooperative behavior between an organization and its stakeholders is maximized when relational partners share both core values and strategic priorities. We explain that high fit along these two dimensions increases trust, relational predictability, attraction/exchange, and communication. We also describe how positive relationships might be formed with fit along only one dimension, and how negative relationships might result in the presence of misfit. Ultimately, we suggest that managers who want to foster positive relationships with stakeholders should concentrate on aligning their values and priorities, rather than simply concentrating on one or the other.  相似文献

The rise of the platform economy has made it a topic of great interest among European policymakers, as evidenced by the European Commission’s 2016 Communication “A European agenda for the collaborative economy”. The regulatory challenges facing policymakers are manifold, ranging from taxation to competition policy to worker protection. Furthermore, many basic aspects of the platform economy are unclear, such as its size, the number of workers who take part in it and, indeed, its very definition. What types of regulation are necessary to ensure that the benefits of the platform economy are maximised for all Europeans? How can the productivity gains associated with the platform economy be distributed throughout society? Perhaps most importantly, how can policymakers support innovation while also protecting consumers, workers and communities?  相似文献

Lieberman and Montgomery note that “…we see benefits from linking empirical findings on first-mover advantages with the complementary stream of research on the resource-based view of the firm” (1998, p. 1111); they suggest that such a link will help explain differences in firm performance. Therefore, this study develops a conceptual framework linking FMAs with the resource-based view of the firm (RBV); in doing so, this framework explains the links between entry timing, resource management, and firm performance. Specifically, this study examines FMAs in light of a four-step resource management process [Morgan RM. Relationship marketing and marketing strategy: the evolution of relationship strategy within the organization. In: Sheth JN, Parvatiyar A, editors. Handbook of Relationship Marketing. Thousand Oaks, California: SAGE Publications, 2000. p. 481–504.; Morgan RM, Hunt S. Relationship-based competitive advantage: the role of relationship marketing in marketing strategy. J Bus Res 1999; 46 (November): 281–90.] consisting of: 1) efficient acquisition (EA), 2) bundling/combining (BC), 3) positioning (POS), and 4) maintenance/protection (MP). The link between FMAs and the resource management process helps explain why so few first movers retain their advantages.  相似文献

WEB-IS, Web-based Integrated System, allows remote, interactive visualization of large-scale 3-D data over the Internet, along with data analysis and data mining. In this paper, we discuss the overall structure of WEB-IS. Up until now we have developed three sub-modules geared towards geophysical problems. WEB-IS1 allows geoscientists to navigate through their 3-D geophysical data, such as seismic structures or numerical simulations, and interactively analyze the statistics or apply data-mining techniques, such as cluster analysis. WEB-IS2 lets a user control Amira (a powerful 3-D visualization package) remotely and analyze, render and view large datasets across the Internet. WEB-IS3 is an imaging service that enables the user to control the scale of features to view through interactive zooming. In the near future, we propose to integrate the three components together through a middleware framework called NaradaBrokering (iNtegrated Asynchronous Real-time Adaptive Distributed Architecture, a distributed messaging infrastructure that can be used to intelligently route data between the originators and registered consumers) without regard for time or location. As a result, WEB-IS will improve its scalability and acquire properties of fault-tolerance. WEB-IS uses a combination of Java, C++, and through the use of NaradaBrokering will seamlessly integrate the server-side processing and user interaction utilities on the client. The server takes care of the processor intensive tasks, such as visualization and data mining, and sends either the resulting bitmap image or statistical results to the middleware across the Internet for viewing. WEB-IS is an easy-to-use service, which will eventually help geoscientists collaborate from different sites in a natural manner. It will be very useful in the next 10 years because of the increasing number of space missions and geophysical campaigns.  相似文献
