Impact of Logistics on Technical Efficiency of World Production (2007–2012)
Networks and Spatial Economics - Tập 16 - Trang 981-995 - 2015
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......
Rumor Transmission in Online Social Networks Under Nash Equilibrium of a Psychological Decision Game
Networks and Spatial Economics - Tập 22 - Trang 831-854 - 2022
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......
The q-Ad Hoc Hub Location Problem for Multi-modal Networks
Networks and Spatial Economics - Tập 17 - Trang 1015-1041 - 2017
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 ......
Congestion Pricing with Heterogeneous Travelers: A General-Equilibrium Welfare Analysis
Networks and Spatial Economics - Tập 4 - Trang 135-160 - 2004
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......
Competitive Location and Pricing on Networks with Random Utilities
Networks and Spatial Economics - Tập 16 - Trang 837-863 - 2015
In this paper we analyze the effect of including price competition into a classical (market entrant’s) competitive location problem. The multinomial logit approach is applied to model the decision process of utility maximizing customers. We provide complexity results and show that, given the locations of all facilities, a fixed-point iteration approach that has previously been introduced in the li......
Advances in Dynamic Traffic Assgmnt: TAC
Networks and Spatial Economics - Tập 15 - Trang 617-634 - 2014
Traditionally traffic assignment problems (TAPs) have been formulated as non-cooperative games (NCGs), and Wardrop’s user equilibrium (UE) of a TAP as Nash equilibrium (NE) of the corresponding NCG. In this study, in contrast, we propose a mapping from finite NCGs (F-NCGs) to asymmetric TAPs (A-TAPs) on a two-way or urban network, in which the travel cost of one link depends on flows on other link......
Investigating the Dynamic Spillover Effects of Low-Cost Airlines on Airport Airfare Through Spatio-Temporal Regression Models
Networks and Spatial Economics - Tập 16 Số 3 - Trang 821-836 - 2016
Integrated Inventory Control and Facility Location Decisions in a Multi-Echelon Supply Chain Network with Hubs
Networks and Spatial Economics - Tập 13 Số 4 - Trang 497-514 - 2013
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......
The Relative Mobility of Vehicles Improves the Performance of Information Flow in Vehicle Ad Hoc Networks
Networks and Spatial Economics - Tập 10 - Trang 209-240 - 2008
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......
