I develop a noisy rational expectations equilibrium model with a continuum of states and a full set of options that render the market complete. I show a major difference in equilibrium behavior between models with constant absolute risk aversion (CARA) and non-CARA preferences. First, when informed traders have non-CARA preferences, all equilibria are fully revealing, independent of the amount ...

We overview some of the major advances in supply chains and transportation networks, with a focus on their common theoretical frameworks and underlying behavioral principles. We emphasize that the foundations of supply chains as network systems can be found in the regional science and spatial economics literature. In addition, transportation network concepts, models, and accompanying methodolog...

In this paper, we establish a dynamic game to allocate CSR (Corporate Social Responsibility) to the members of a supply chain. We propose a model of a three-tier supply chain in a decentralized state which includes a supplier, a manufacturer and a retailer. For analyzing supply chain performance in decentralized state and the relationships between the members of the supply chain, we use a Stack...

We set up a two level supply chain model which consists of one manufacturer and two retailers in this paper. Necessities as the main research object, we develop the nonlinear demand function of products which is more related to the reality. In order to increase the performance of whole supply chain in the decentralized decision, we introduce revenue sharing mechanism in this paper. Through nume...

In this paper, we show how sustainable supply chains can be transformed into and studied as transportation networks. Specifically, we develop a new supply chain model in which the manufacturers can produce the homogeneous product in different manufacturing plants with associated distinct environmental emissions. We assume that the manufacturers, the retailers with which they transact, as well a...

in this paper, two sets of sufficient conditions are obtained to ensure the existence and stability of a unique equilibrium point of unforced first-order fuzzy relational dynamical systems by using two different approaches which are both based on the fuzzy relational matrix of the model.in the first approach, the equilibrium point of the system is one of the centers of the related membership fu...

study of the variables which explain real exchange rate fluctuations and real exchange rate deviation from its long-run equilibrium path, indicates that these variables have negative effects on the supply of agricultural products, for export. therefore,it seems that any attempt on stabilizing real exchang rate and bringing it closer to its equilibrium rate can be favorable in the expansion of e...

This paper studies sequence economies over an infinite horizon with general security structures. Assumptions are given under which a pseudo-equilibrium exists for all economies and an equilibrium exists for a dense set of (appropriately parameterized) economies. Under these assumptions the indebtedness of the agents in equilibrium can be limited either by an explicit bound on their debts or by ...

An aggregate game is a normal-form game with the property that each player’s payoff is a function only of his own strategy and an aggregate function of the strategy profile of all players. Aggregate games possess a set of purely algebraic properties that can often provide simple characterizations of equilibrium aggregates without first requiring that one solves for the equilibrium strategy prof...

When supply disruption occurs following major disasters, many supply chains tend to breakdown due to stock-outs or lost sales and take a long time to recover. However, by keeping one or more emergency sources of supply, some supply chains continue to function smoothly, satisfying consumer demand even after a major disaster. In this study, we use the game-theory-based framework to model a supply...
