aBstraCt In this document it is analyzed the importance of contracts for coordination between two companies in a supply chain. In the studied situation, one company, or supplier, supplies one product to the other company, who is a retailer. The companies are going to coordinate by two types of decisions: economic (concerning prices fixed on a contract), and physical exchange (concerning the inv...

This work focus mainly on a specific question: for an adopted contract, what are the decisions to be taken for each company taking into account his own interests, knowing that these decisions influence the behavior of the other company and in consequence the coordination of the chain. This may be also explained using the terms of Cachon (2004) who clearly presents this situation: “Optimal suppl...

In this paper we consider the problem of double implementation of Linear Cost Share Equilibrium (LCSE) allocations by a feasible and continuous mechanism whose Nash allocations and strong Nash allocations coincide with Linear Cost Share Equilibrium allocations. The mechanism presented here allows preferences and initial endowments as well as coalition patterns to be privately observed, a featur...

In 2008, the European Union Commission put forward a proposal for a new directive on renewable forms of energy. Each of the member states should increase its share of renewable energies in an effort to boost the total share of the EU from the current 8.5% to 20% by 2020. The level of renewable energy in Finland was 28.5% in 2005, and the national target share of renewable energy by 2020 is 38%....

Furthermore, no role whatsoever is assumed for externalities. If we accept that there is interaction between production factors, and these 1actors, bec...

Providing sustainable energy is one of the fundamental challenges for mankind. With energy usage being a part of everyday activities and with the increasingly diversity of energy creation this is an inherently multidisciplinary problem. Transportation and travel, heating and cooling, manufacturing and production are major areas in which energy is used and all these domains become more and more ...
