Are local food chains more sustainable than global food chains? Considerations for assessment
2016
© 2016 by the authors; licensee MDPI, Basel, Switzerland. This paper summarizes the main findings of the GLAMUR project which starts with an apparently simple question: is "local" more sustainable than "global"? Sustainability assessment is framed within a post-normal science perspective, advocating the integration of public deliberation and scientific research. The assessment spans 39 local, intermediate and global supply chain case studies across different commodities and countries. Assessment criteria cover environmental, economic, social, health and ethical sustainability dimensions. A closer view of the food system demonstrates a highly dynamic local-global continuum where actors, whil…
Managing in-country transportation risks in humanitarian supply chains by logistics service providers: Insights from the 2015 Nepal earthquake
2017
International audience; Humanitarian supply chains (HSCs) play a central role in effective and efficient disaster relief operations. Transportation has a critical share in HSCs and managing its risks helps to avoid further disruptions in relief operations. However, there is no common approach to or culture of risk management that its applicability has been studied through recent cases. This paper incorporates an empirical research design and makes a threefold contribution: first, it identifies in-country transportation risks during Nepal response. Second, we evaluate afore identified risks through an expert driven risk assessment grid. Third, we use our field data to study how some humanita…
Intellectual property management between buyer-supplier in the crowdsourcing context
2017
In this paper we investigate the antecedents of buyers’ decisions related to the management of the IPR generated by the suppliers in crowdsourcing contests. Leveraging on Property Rights Theory and interview data, we examine how contest’ attributes affect two buyers’ decisions about (1) whether to define an IPR arrangement ex-ante or negotiating it ex-post with the winning supplier; (2) the choice between strong or weak ownership levels of the IPR arrangement. To test the developed hypotheses, we build a dataset of 819 contests broadcasted on InnoCentive (from 2010 to 2016). Our findings contribute to both the operations management and the crowdsourcing literatures.
Adapting to supply chain 4.0: an explorative study of multinational companies
2019
The aim of this paper is to examine how multinational companies from five industries can adapt to what we call Supply Chain 4.0; the supply chain created as a result of the new digital era brought ...
International Inflation Spillovers through Input Linkages
2019
We document that international input-output linkages contribute substantially to synchronizing producer price inflation (PPI) across countries. Using a multicountry, industry-level data set that combines information on PPI and exchange rates with global input-output linkages, we recover the underlying cost shocks that are propagated internationally via the global input-output network, thus generating the observed dynamics of PPI. We then compare the extent to which common global factors account for the variation in actual PPI and in the underlying cost shocks. Across a range of econometric tests, input-output linkages account for half of the global component of PPI inflation.
The expected value of the traceability information
2015
Abstract Recent regulations on agri-food traceability prescribe traceability throughout the entire supply chain, in order to ensure consumers’ safety and product quality. This has led producers and retailers to consider the opportunity to improve the firm's reputation and consumer confidence through the implementation of traceability systems designed not only to satisfy the legal requirements, but also to track the quality of the products through the supply chain for optimization purposes. However the actual implementation of such systems depends on the possibility of gathering specific information related to the product quality. Nowadays, innovative and non invasive technologies such as th…

On the Bullwhip Avoidance Phase: The Synchronised Supply Chain
2012
Abstract The aim of this paper is to analyse the operational response of a Synchronised Supply Chain (SSC). To do so, first a new mathematical model of a SSC is presented. An exhaustive Latin Square design of experiments is adopted in order to perform a boundary variation analysis of the main three parameters of the periodic review smoothing ( S , R ) order-up-to policy: i.e., lead time, demand smoothing forecasting factor, and proportional controller of the replenishment rule. The model is then evaluated under a variety of performance measures based on internal process benefits and customer benefits. The main results of the analysis are: (I) SSC responds to violent changes in demand by re…
Insights on Partial Information Sharing in Supply Chain dynamics
2015
This paper provides an assessment of partial Information Sharing (IS) in Supply Chain (SC). We study the dynamics of collaborative multi-echelon structure, characterized by an increasing level of information visibility among partners. To do so, we mathematically model six four-echelon serial SCs via difference equations and conduct numerical simulations on the basis of a robust design of experiment. Results shows how (1) as the extent of IS increases, the performance of whole SC improves as well, and (2) the impact of IS depends not on which particular members are involved but on the number of collaborative members.
Partial/Asymmetrical Information sharing in Supply Chain: A bibliometric analysis
2016
The importance of Information Sharing (IS) between an enterprise and its customers or cooperating companies has been long recognized in Supply Chain (SC) research literature. In this paper we perform an exploratory analysis of the current state-of-art and challenges in the field of partial/asymmetrical IS in SC. To fulfil our objective we carry out a bibliometric analysis by adopting BibExcel and Gephi tools. We identify 115 articles and generate several co-citation maps. Our results show that the concepts of partial and asymmetrical IS in SCs are not well defined in literature.
