Supply chain configuration under information sharing

This paper examines the effect of information sharing on supply chain configuration where the market characterized by demand uncertainty. A dynamic multi-stage game theoretic model with incomplete information is employed to capture the sequence of events. Our supply chain consists of two suppliers with exogenous wholesale prices and two retailers, the incumbent and the entrant, with asymmetric demand information. Informed incumbent prefers to conceal its private information from the entrant in order to reap more profits in the market. The channel of information flows is only through the first supplier and the incumbent can supply just from him, but the entrant is free to choose its proper supplier considering the point that the second supplier is uninformed. Our analytical model demonstrates that how the mean demand of the market, wherein our retailers compete, and its relation with the relative wholesale price of the suppliers play crucial role in equilibrium determination. Our results show under which circumstances separation and pooling equilibrium could occur in some range of demand variation. It is also shown that the entrant sometimes prefers to avoid information acquisition by choosing the second supplier and playing Cournot instead of Stackelberg which is more profitable for him in some occasions

The effect of vertical knowledge spillovers via the supply chain on location decision of firms

In this paper a game theoretic model is employed to analyze the relationship between strategic location decision of firms in the supply chain considering the role of horizontal and vertical knowledge spillovers, and numerical approach is applied to characterize the equilibria of the considered multi-stage game. Geographical concentration or isolation as equilibrium outcome is determined based on our different parameterizations and two scenarios each consists of two separated cases, which we establish according to the location of our agents. In the first scenario both suppliers are supposed to be located in different regions while in the second one they act in a same region. In addition, first case of each scenario considers geographical isolation of two producers whereas second case investigates the geographical concentration. Furthermore, the effect of different technological level of our agents on their final location decision is investigated

The Effect of Salvage Market on Strategic Technology Choice and Capacity Investment Decision of Firm under Demand Uncertainty

This paper examines the effect of salvage market on strategic technology choice and capacity investment decision of two firms that compete on the amount of output they produce under demand uncertainty. A game theoretic model applies such that in the first stage firms choose their production technology between two alternatives: modular production process (flexible technology) or unified production process (inflexible technology). Then at the second stage they decide on the amount of capacity investment: flexible firm makes decision about general and specific components’ capacity and inflexible firm just about unified component (final product). One stage forward both enter the primary market in which demand is uncertain and play a duopoly Cournot game on the amount of quantity they manufacture and finally at the last stage, flexible firm will be able to sell its unsold general components in the secondary market (salvage market) with a deterministic price. Solving optimization problems of the model results in intractable equations which lead us to employ numerical studies considering a specific probability distribution to observe equilibrium behavior of competing firms. Broad range of parameters with respect to established relationships among them have been examined in order to cover all the possible economically reasonable scenarios. Findings are expressed explicitly in the form of observations where we demonstrate that with symmetric parameterization there is a unique symmetric Nash equilibrium in which both firms choose inflexible technology while applying asymmetric parameters has the potential to form two types of equilibrium when 1. Both firms choose inflexible technology or 2. Only one firm chooses flexible technology. Moreover it is shown that there is a specific unified cost threshold that could shift the equilibrium of the game. Finally we discuss on the case that there is no equilibrium and mention some managerial implications of the model

Effect of salvage market on strategic technology choice and capacity investment decision of firm under demand uncertainty

This paper examines the effect of salvage market on technology choice and capacity investment decision of two firms that compete on quantity under demand uncertainty. A game theoretic model applies such that firms choose their production technology between two alternatives: flexible versus inflexible production process. Then they decide on the amount of capacity investment: flexible firm makes decision about general and specific components and inflexible firm just about unified component. One stage forward both enter the primary market in which demand is uncertain and play a la Cournot and finally, flexible firm will be able to sell its unsold general components in the secondary market with a deterministic price. Numerical study was employed to observe equilibrium behavior of firms. Findings demonstrate that with symmetric parameterization there is a unique Nash equilibrium in which both firms choose inflexible technology while applying asymmetric parameters has the potential to form two types of equilibrium when both firms choose inflexible technology or only one firm chooses flexible technology. Moreover, it is shown that there is a cost threshold that could shift the equilibria

A New Framework for Learning Approaches toward Social Evolution of Organizations

Abstract This paper addresses a gap in the literature concerning suitability of organizational learning approaches in facing social responsibility challenges, and proposes a developed framework that could proactively bridge this gap. A new framework is designed in order to gain insight on the relationships between the typical organizational learning approaches-which have been discussed extensively so far in the literature-and the brandnew concept of civil learning come out of Corporate Social Responsibility (CSR) studies in very recent years. Comparative analysis is employed to identify well-adjusted organizational learning approaches toward social evolution of organizations. Indeed we are looking to propose a specific learning framework for the firms that are tackling with CSR issues. Hence, we qualitatively bridge between organizational learning models and social learning approaches in order to foster a more advanced framework which recommends the employment of specific learning methods and styles to deal with CSR challenges based on the features of the firm and its business contextual considerations.
