In this paper, we develop a unified variational inequality framework in the context of spatial price network equilibrium problems that captures world trade policies in the form of tariff rate quotas, which are two-tiered tariffs, and that have been applied in practice to numerous commodities....

In this paper, we develop a global supply chain network model in which profit-maximizing firms engage in competition in the production and distribution of products in the presence of quantitative trade policy instruments in the form of tariff rate quotas. Tariff rate quotas are two-tiered...

In this paper, we demonstrate how to capture the robustness of a transportation network in the case of degradable links represented by decreasing capacities. In particular, with the use of Bureau of Public Road user link travel cost functions, we propose two relative total cost indices to assess...

In this paper, we propose a network performance/efficiency measure for the evaluation of financial networks with intermediation. The measure captures risk, transaction cost, price, transaction flow, revenue, and demand information in the context of the decision-makers' behavior in multitiered...

Globalization and technological advances, notably, in telecommunications networks and in the development of new financial instruments, have transformed the financial services landscape and their impacts have been studied empirically. In this paper, in contrast, we focus on the theoretical...

In this paper, we develop an international financial network model in which the sources of funds and the intermediaries are multicriteria decision-makers and are concerned with both net revenue maximization and risk minimization. The model allows for both physical as well as electronic...

In this paper, we demonstrate how a new network performance/efficiency measure, which captures demands, flows, costs, and behavior on networks, can be used to assess the importance of network components and their rankings.We provide new results regarding the measure, which we refer to as the...

In this paper, we develop multiproduct supply chain network models with explicit capacities, prior to and post their horizontal integration. In addition, we propose a measure, which allows one to quantify and assess, from a supply chain network perspective, the synergy benefits associated with...

In this paper, we develop a new supply chain network model with multiple decision-makers associated at different tiers and with multiple transportation modes for shipment of the good between tiers. The model formulation captures supply side risk as well as demand-side risk, along with...

In this paper, we present a new theoretical framework for the quantification of strategic advantages associated with horizontal mergers through the integration of supply chain networks. The framework is a system-optimization one in which each firm is represented as a network of economic...
