Model Development for Manufacturer Price and Retailer Service Competition in a Duopoly Common Retailer Channel

A model had been considered where there is price competition between two manufacturers and one retailer. Subsequently, this model was extended by including price competition between two manufacturers and two retailers. Moreover, price and service competition had been studied where there are two manufacturers producing competing products and selling them through a common retailer. The consumer demand depends on two factors: (1) retail price and (2) service level provided by the manufacturer. In this study, a channel structure in which there are duopoly manufacturers and duopoly common retailers in competition between channel members under wholesale price and retail’s margin and service provided by retailer was studied. Customer demand depends on two factors: (1) price and (2) service level provided by the retailer. Both of these manufacturers produce competing products and sell their products to both common retailers. This study focuses on the role of service provided by the retailer, how the bargaining power can affect the decision variables and channel member’s profit, when there is competition between the retailers service and margin and manufacturers price (decision variables). To overcome this problem a solution on the effect of bargaining power to supply chain equilibrium was studied. The demand function model was developed by considering service by retailer in duopoly retailer channel structure. The effect of bargaining power on equilibrium solution when the manufacturer or the retailer is a leader, and the effect of increase production cost and market base and price and service competition index on the channel’s decision variables was determined. The game theory approach was used to derive equilibrium solutions for wholesale prices, retailer margins and service, and profits for each channel member. To study the effect of bargaining power in this supply chain equilibrium solution, Manufacturer Stackelberg, Retailer Stackelberg, and Vertical Nash were used. In this study, it was shown that customers receive the least benefit from service when the retailer is leader. They are better off when the manufacturer is leader. The effect of changes in price competition indexes (b p , θ p ), service competition indexes (bs , θ s ), production cost ( ), and market base ( ) on market sensitivity were analyzed. The result showed that when c of one manufacturer increases, the firm can sell its product at a higher price and with lower quantity but its competitor benefits. By increasing the market base of one of the manufacturers, the wholesale and retail price increase. When customer tends to choose a product with lower price, the manufacturer sells its product with lower wholesale price. Since, it was assumed that the cost of providing service increases by the power of 2, it is not economical to invest in service. Therefore, by increasing ci aij i θ sand bs the service level first increases and then decreases

Bargaining and Influence in Conflict Situations

[Excerpt] This chapter examines bargaining as an influence process through which actors attempt to resolve a social conflict. Conflict occurs when two or more interdependent actors have incompatible preferences and perceive or anticipate resistance from each other (Blalock 1989; Kriesberg 1982). Bargaining is a basic form of goal-directed action that involves both intentions to influence and efforts by each actor to carry out these intentions. Tactics are verbal and/or nonverbal actions designed to maneuver oneself into a favorable position vis-a-vis another or to reach some accommodation. Our treatment of bargaining subsumes the concept of negotiation (see Morley and Stephenson 1977). This chapter is organized around a conceptual framework that distinguishes basic types of bargaining contexts. We begin by introducing the framework and then present an overview of and analyze theoretical and empirical work on each type of bargaining context

Client-contractor bargaining on net present value in project scheduling with limited resources

The client-contractor bargaining problem addressed here is in the context of a multi-mode resource constrained project scheduling problem with discounted cash flows, which is formulated as a progress payments model. In this model, the contractor receives payments from the client at predetermined regular time intervals. The last payment is paid at the first predetermined payment point right after project completion. The second payment model considered in this paper is the one with payments at activity completions. The project is represented on an Activity-on-Node (AON) project network. Activity durations are assumed to be deterministic. The project duration is bounded from above by a deadline imposed by the client, which constitutes a hard constraint. The bargaining objective is to maximize the bargaining objective function comprised of the objectives of both the client and the contractor. The bargaining objective function is expected to reflect the two-party nature of the problem environment and seeks a compromise between the client and the contractor. The bargaining power concept is introduced into the problem by the bargaining power weights used in the bargaining objective function. Simulated annealing algorithm and genetic algorithm approaches are proposed as solution procedures. The proposed solution methods are tested with respect to solution quality and solution times. Sensitivity analyses are conducted among different parameters used in the model, namely the profit margin, the discount rate, and the bargaining power weights

Coverage games in small cells networks

This paper considers the problem of cooperative power control in distributed small cell wireless networks. We introduce a novel framework, based on repeated games, which models the interactions of the different transmit base stations in the downlink. By exploiting the specific structure of the game, we show that we can improve the system performance by selecting the Pareto optimal solution as well as reduce the price of stability

On centralized bargaining in a symmetric oligopolistic industry

In this paper we study interactions between labor and product markets, in an imperfectly competitive industry with centralized wage bargaining. Firms jointly bargain with the union over wages and then compete in prices or quantities. We show that the negotiated wage is independent of the number of firms, the degree of substitutability of firms' products, and the type of market competition, in a broad c1ass of industry specifications, including the standard syrnmetric linear demand system-linear one factor (labor) technology. This result is robust to various union objectives. Thus, unions are better-off as the market becomes more competitive because aggregate! employment increases. Finally,. motivated by the wage independence property, we propose that the bargained wage in a Bertrand homogenous market be taken as the limit of that of a differentiated market as the degree of substitutability goes to one

Reforming an Asymmetric Union: On the Virtues of Dual Tier Capital Taxation

The tax competition for mobile capital, in particular the reluctance of small countries to agree on measures of tax coordination, has ongoing political and economic fallouts within Europe. We analyse the effects of introducing a two tier structure of capital taxation, where the asymmetric member states of a union choose a common, federal tax rate in the first stage, and then non-cooperatively set local tax rates in the second stage. We show that this mechanism effectively reduces competition for mobile capital between the members of the union. Moreover, it distributes the gains across the heterogeneous states in a way that yields a strict Pareto improvement over a one tier system of purely local tax choices. Finally, we present simulation results, and show that a dual structure of capital taxation has advantages even when side payments are feasible

Wage bargaining and the boundaries of the multinational firm

Do variations in labor market institutions across countries affect the cross-border organization of the firm? Using firm-level data on multinationals located in France, we show that firms are more likely to outsource the production of intermediate inputs to external suppliers when importing from countries with empowered unions. Moreover, this effect is stronger for firms operating in capital-intensive industries. We propose a theoretical mechanism that rationalizes these findings. The fragmentation of the value chain weakens the union's bargaining position, by limiting the amount of revenues that are subject to union extraction. The outsourcing strategy reduces the share of surplus that is appropriated by the union, which enhances the firm's incentives to invest. Since investment creates relatively more value in capital-intensive industries, increases in union power are more likely to be conducive to outsourcing in those industries. Overall, our findings suggest that multinational firms use their organizational structure strategically when sourcing intermediate inputs from unionized markets

Controlled Matching Game for Resource Allocation and User Association in WLANs

In multi-rate IEEE 802.11 WLANs, the traditional user association based on the strongest received signal and the well known anomaly of the MAC protocol can lead to overloaded Access Points (APs), and poor or heterogeneous performance. Our goal is to propose an alternative game-theoretic approach for association. We model the joint resource allocation and user association as a matching game with complementarities and peer effects consisting of selfish players solely interested in their individual throughputs. Using recent game-theoretic results we first show that various resource sharing protocols actually fall in the scope of the set of stability-inducing resource allocation schemes. The game makes an extensive use of the Nash bargaining and some of its related properties that allow to control the incentives of the players. We show that the proposed mechanism can greatly improve the efficiency of 802.11 with heterogeneous nodes and reduce the negative impact of peer effects such as its MAC anomaly. The mechanism can be implemented as a virtual connectivity management layer to achieve efficient APs-user associations without modification of the MAC layer
