Impact of Logistics on Technical Efficiency of World Production (2007–2012)Networks and Spatial Economics - Tập 16 - Trang 981-995 - 2015
Pablo Coto-Millán, Xose Luís Fernández, Miguel Ángel Pesquera, Manuel Agüeros
This research uses a production function of the type proposed by Mankiw et al. (1992) to study the effect of logistics and information and communication technologies (ITC) on domestic technical efficiency using stochastic frontier analysis for thirty-four countries over the period 2007–2012. We find that logistics and ICT are important channels for improving efficiency. This paper contributes to t...... hiện toàn bộ
Rumor Transmission in Online Social Networks Under Nash Equilibrium of a Psychological Decision GameNetworks and Spatial Economics - Tập 22 - Trang 831-854 - 2022
Wenjia Liu, Jian Wang, Yanfeng Ouyang
This paper investigates rumor transmission over online social networks, such as those via Facebook or Twitter, where users liberally generate visible content to their followers, and the attractiveness of rumors varies over time and gives rise to opposition such as counter-rumors. All users in social media platforms are modeled as nodes in one of five compartments of a directed random graph: suscep...... hiện toàn bộ
The q-Ad Hoc Hub Location Problem for Multi-modal NetworksNetworks and Spatial Economics - Tập 17 - Trang 1015-1041 - 2017
Hyun Kim, Megan S. Ryerson
This research proposes a spatial optimization problem over a multi-modal transportation network, termed the q-Ad-hoc hub location problem (AHLP), to utilize alternative hubs in an ad-hoc manner in the wake of a hub outage. The model aims to reorganize the spatial structure of disrupted networks: unaffected hubs are utilized as ad-hoc hubs through which alternative routes connect supply and demand ...... hiện toàn bộ
Congestion Pricing with Heterogeneous Travelers: A General-Equilibrium Welfare AnalysisNetworks and Spatial Economics - Tập 4 - Trang 135-160 - 2004
André de Palma, Robin Lindsey
Traffic congestion pricing is studied using a general-equilibrium framework that incorporates public goods expenditures, an income tax, a government budget constraint, and preferences for equity. Individuals differ with respect to wages, values of travel time, and the congestion characteristics of their vehicles. Formulae for optimal tolls are derived and decomposed to reveal the separate influenc...... hiện toàn bộ
Integrated Inventory Control and Facility Location Decisions in a Multi-Echelon Supply Chain Network with HubsNetworks and Spatial Economics - Tập 13 Số 4 - Trang 497-514 - 2013
Shahabi, Mehrdad, Akbarinasaji, Shirin, Unnikrishnan, Avinash, James, Rachel
This paper develops mathematical models to coordinate facility location and inventory control for a four-echelon supply chain network consisting of multiple suppliers, warehouses, hubs and retailers. The hubs help in reducing transportation costs by consolidating products from multiple warehouses and directing the larger shipments to the retailer. The integrated models studied in this paper simult...... hiện toàn bộ
The Relative Mobility of Vehicles Improves the Performance of Information Flow in Vehicle Ad Hoc NetworksNetworks and Spatial Economics - Tập 10 - Trang 209-240 - 2008
Lili Du, Satish Ukkusuri
Vehicular ad hoc networks (VANET) are receiving significant attention due to their potential to provide a wide range of benefits. One key distinguishing feature of VANET from other ad hoc networks is their relative vehicular mobility. Therefore, to fully understand the significant benefits of these systems, it is necessary to understand the interaction between traffic flow characteristics and info...... hiện toàn bộ
The Accumulation of Empty Containers in Urban Areas: Policy Implications from a Stochastic FormulationNetworks and Spatial Economics - Tập 14 - Trang 379-408 - 2014
Noel Pérez-Rodríguez, Jose Holguín-Veras
The accumulation of empty cargo containers in urban areas is an important issue for communities and policy makers as these containers seem to restrict the use of valuable land and diminish the quality of life of communities close to ports and storage depots. Different reasons have been offered to explain this accumulation, with no definite answer. This paper examines the validity of the most frequ...... hiện toàn bộ
A Hybrid Route Choice Model for Dynamic Traffic AssignmentNetworks and Spatial Economics - Tập 13 - Trang 183-203 - 2012
Zhen (Sean) Qian, H. Michael Zhang
Network user equilibrium or user optimum is an ideal state that can hardly be achieved in real traffic. More often than not, every day traffic tends to be in disequilibrium rather than equilibrium, thanks to uncertainties in demand and supply of the network. In this paper we propose a hybrid route choice model for studying non-equilibrium traffic. It combines pre-trip route choice and en-route rou...... hiện toàn bộ
Are ‘Sister Cities’ from ‘Sister Provinces’? An Exploratory Study of Sister City Relations (SCRs) in ChinaNetworks and Spatial Economics - Tập 18 - Trang 473-491 - 2018
Xingjian Liu, Xiaohui Hu
Sister city relations (SCRs) represent a significant but less well researched type of inter-city (regional) networks. While most analyses of the connectivity of Chinese cities focus on economic linkages such as air traffic flows and corporate connections, limited attention has been paid to SCRs, as an emerging mediator in affecting global inter-city networks. This study not only summarizes the key...... hiện toàn bộ
