Stability of collusion in differentiated oligopolies is studied without symmetry restrictions on the available strategies. It is demonstrated that if the number of firms is sufficiently large, two-phase stick-and-carrot punishment schemes apply at the highest possible discount rate with respect to collusion on the joint profit-maximizing output. If stick-and-carrot punishment schemes are used, ...

For the replacement of fossil fuel forestry biomass should help mitigating Green House Gas (GHG) emissions. However the supply of energy wood is challenging because of high supply costs and rapidly increasing demand. Considering the typical, heterogeneous structure of landownership, contractors and energy producers in Mid-Europe, supply network optimization becomes of major importance. Mathemat...

the choice of which products to stock among numerous competing products and how much space to allocate to those products are central decisions for retailers. this study aimed to apply data mining approach so that, we got needed information from large datasets of sale transactions to find the relations between products and to make product assortments. thus, we represented a model for product ass...

in the restructured environment of electricity market, firstly the generating companies and the customers are looking for maximizing their profit and secondly independent system operator is looking for the stability of the power network and maximizing social welfare. in this paper, a one way auction in the electricity market for the generator companies is considered in both perfect and imperfec...

This paper examines incentive-wage effects for production and for managerial/technical workers in both urban and rural Chinese non-agricultural enterprises. We report strong evidence of productivity-enhancing wage behavior among enterprises in all ownership categories. There is also evidence that firms paying higher efficiency wages experience less shirking among their employees. We find that t...

Je vous le recommande : impact de l'intéressement aux bénéfices sur la pertinence des recommandations en ligne Abstract Recommender systems are commonly used by Internet firms to improve consumers' shopping experience and increase firm sales and profits. A large stream of work on recommender design has studied the problem of identifying the most relevant items to recommend to users. In parallel...

This article deals with strategic control of price and information in a single-server model. It considers an M/M/1 system with identical customers. There is a single cut-off number, and the level of congestion is said to be low (high) if the queue length is less than (at least) this value. The firm can dynamically change the admission fee according to congestion level. Arriving customers cannot...

Recent papers have argued that a monopoly firm might be able to maximize its profit by allowing some customers to steal its product. In particular, with network externalities, it is claimed that allowing piracy can be profitable because it increases the user base of the product and raises the willingness-to-pay of other customers. In this paper we analyze these claims when the producer can free...

We apply backward induction to derive optimal price functions. In the second period, given first period price p 1 , the firm selects second period price p 2 (p 2 < Max{q, R}) to maximize its second period profit: The profit function can be reduced to four possibilities based on the value of p 1 : By maximizing profit in each of the four cases, we can derive the optimal second period price p 2 a...

The fair profit distribution problem of a typical supply chain network involving batch production is considered in this article. To implement this concept, we construct a multi-product batch production combined with multi-stage distribution planning model to achieve multiple objectives such as maximizing the customer service level, maximizing the profit of each participant company of the supply...
