This article applies multiobjective optimization to show how the tradeoffs between cost and carbon emissions may be obtained in the context of sustainable operations. We formulate a model where transportation mode selection and order quantity decisions are considered jointly. We derive structural properties of the model and develop several insights. First, we show that switching to a greener mode of transportation while continuing to optimize the total logistics costs function may lead to a dominated solution. Second, we prove that the modal shift occurs only under strong carbon emissions reduction requirements. Third, we show that the efficient frontier is non-convex and we analyze some implications. Finally, we analyze the impacts of an increase in truck capacity. The results are illustrated through an example of a French retailer. © 2016 Springer Science+Business Media New York Source

Intermodal transportation is often presented as an efficient solution for reducing carbon emissions without compromising economic growth. In this article, we present a new intermodal network design model in which both the terminal location and the allocation between direct truck transportation and intermodal transportation are optimized. This model allows for studying the dynamics of intermodal transportation solutions in the context of hinterland networks from a cost, carbon emissions and modal shift perspective. We show that maximizing the modal shift is harmful for both cost and carbon emissions and that there is a carbon optimal level of modal shift. We also show that even if transportation cost and carbon emissions share the same structure, these two objectives lead to different solutions and that the terminal is located closer to the port when optimizing cost and further away when optimizing carbon emissions. The model also allows for studying the tradeoff between distance and volume, the impact of using aggregated models for estimating train transportation cost and carbon emissions as well as the potential policy measures that enable aligning cost and carbon emissions. © 2014 Elsevier B.V.

For a geographical approach of convergence. Regional disparities in the European Union and their evolution.-The aim of this paper is to lay the conceptual and methodological foundations for a theory of economic convergence. Taking into account the spatial dimension when evaluating convergence is from this point of view an interesting perspective in the field of the geography. The index of local economic convergence proposed makes it possible to measure the simultaneous processes of economic convergence and divergence occurring in the European Union. By comparing the two periods 1995-2000 and 2000-2006 for all the European regions at the NUTS 23 level, it can be seen that there are situations of regions that have evolved in a favorable or unfavorable manner from the economic point of view. The spatial structure of these local economic convergence or divergence phenomena is very clear and reflects a true geography of the evolution of regional inequalities in the European Union. © Belin.

The aim of this paper is to lay emphasis on the main factors (economic, historical, structural, etc.) that affect Italian agri-food exports in the non-EU Mediterranean Partner Countries (MPCs). The authors estimate a gravity equation including some of the main variables found in the reference literature useful to highlight the main factors which influence the bilateral exchanges. The results show that the variables traditionally included in the gravity equation present the expected sign. In particular, Italian agri-food exports towards its neighbouring Mediterranean countries are positively affected by income of partner countries, colonial and historical ties, geographical proximity and the lack of importance of the agricultural sector in some partner countries.

This article responds to the identified considerations and gaps in existing research on the way a new idea is transformed into a market-accepted new product. Utilizing the findings of an extensive theoretical analysis and empirical investigation on the subject, this research studies new product development within a wider strategic marketing context. The research interrelates three different perspectives: the process-defining perspective, that identifies and refines the managerial implications and theoretical considerations; the value-defining perspective, which investigates the various types and stakeholders of value; and the context-defining (contemporary consumer behavior and strategic marketing) perspective, which positions the entire innovation process within the comprehensive set of environmental and organizational processes and factors. The article concludes with the development of a preliminary Contemporary Strategic Framework for New Product Development. The framework answers the various theoretical considerations on the subject, incorporating the various processes' stages and interrelationships within a single descriptive system. In addition, it provides constructive functional managerial value through potential practical implementation and prescriptive interpretation. © 2012 Copyright Taylor and Francis Group, LLC. Source
