Recent years have seen considerable interest in the impact of contract farming on farmers in developing countries, motivated out of belief that contract farming spurs the transition to modern agriculture. In this paper, we provide a thorough review of the empirical literature on contract farming in both developed and developing countries, paying careful attention to broad implications of this r...

In the context of economy globalization, the need for globally distributed negotiations involving a high number of negotiators communicating through the Internet becomes an important business issue. In such negotiations, the amount of information describing the negotiation process is too high to be easily understood by humans. In this paper, a negotiation support model adapted to highly concurr...

We study the interaction of long-term contracting and spot market transactions between Multi-Gencos and MultiDiscos for electric power. Gencos and Discos may either contract for delivery in advance or they may sell/buy some or all of their output/input in a spot market. Contract pricing involves both a reservation fee per unit of capacity and an execution fee per unit of output if capacity is c...

The CP contract is shown to have advantages over both component contracts in terms of supply chain coordination, profit allocation, and risk allocation. In particular, we obtain the following results: (a) as long...

We show that for infinite transition systems induced by cryptographic protocols in the Rusinowitch/Turuani style certain fundamental branching properties are decidable. As a consequence, we obtain that crucial properties of contract-signing protocols such as balance are de-

Real-world dispute resolution should be guided by laws, even if such disputes may be resolved by bodies other than the court of laws. Hence in order to build contract dispute resolution systems we need a tool capable of representing, reasoning and programming with contract laws. In this paper we present such a tool called MoDiSo (MOdular Argumentation for DIspute ReSOlution) which combines the ...
