An Efficient Protocol for Negotiation over Combinatorial Domains with Incomplete Information

We study the problem of agent-based negotiation in combinatorial domains. It is difficult to reach optimal agreements in bilateral or multi-lateral negotiations when the agents' preferences for the possible alternatives are not common knowledge. Self-interested agents often end up negotiating inefficient agreements in such situations. In this paper, we present a protocol for negotiation in combinatorial domains which can lead rational agents to reach optimal agreements under incomplete information setting. Our proposed protocol enables the negotiating agents to identify efficient solutions using distributed search that visits only a small subspace of the whole outcome space. Moreover, the proposed protocol is sufficiently general that it is applicable to most preference representation models in combinatorial domains. We also present results of experiments that demonstrate the feasibility and computational efficiency of our approach

Conditionality, separation, and open rules in multilateral institutions

We examine the implications for the viability of multilateral cooperation of different legal principles governing how separate international agreements relate to each other. We contrast three alternative legal regimes: conditionality - making cooperation in one area a condition for cooperation in another - separation - forbidding sanctions in one area to be used to enforce cooperation in others - and open rules, i.e. absence of any restriction on the patterns of cross-issue cooperation arrangements and sanctions. As an example, we focus on a scenario where countries can enter into selective and separate binding trade and environmental agreements with different partners. Our analysis suggests that conditionality is more likely to facilitate multilateral, multi-issue cooperation in situations where the environmental policy stakes are small relative to the welfare effects of trade policies; when the costs of environmental compliance are high, a conditionality rule can hinder multilateral cooperation. Separation can undermine cooperation by limiting punishment, but can also promote broad cooperation by making partial cooperation more diffcult to sustain. Thus, how different linkage regimes affect multilateral negotiations depends on the structure of cooperation incentives for the countries involved

Issue Linkage and Issue Tie-in in Multilateral Negotiations

We describe a model of international, multidimensional policy coordination where countries can enter into selective and separate agreements with different partners along different policy dimensions. The model is used to examine the implications of negotiation tie-in - the requirement that agreements must span multiple dimensions of interaction - for the viability of multilateral cooperation when countries are linked by international trade flows and transboundary pollution. We show that, while in some cases negotiation tie-in has either no effect or can make multilateral cooperation more viable, in others a formal tie-in constraint can make an otherwise viable joint multilateral agreement unstable.international cooperation, trade and environmental policy negotiations

An Economic Perspective on Russia's Accession to the WTO

Russia's application for accession to the WTO is currently in its final phases and may be completed by the end of 2003. In this context, this paper provides some background information on Russia's recent policy and structural reforms, the composition and geographic distribution of trade, tariff rates by commodity groups, and other aspects of trade and domestic policies at issue in the accession process. The accession proce-dure and the current status of the accession process are then discussed. Using a computable general equilibrium (CGE) modeling analysis of China's WTO accession as a prototype, the potential use of CGE model-ing of Russian accession is considered as well as Russia's participation in the Doha Development Round and preferential trading arrangements. It is concluded that Russia may realize significant benefits from WTO accession and from the multilateral trade liberalization to be effected in the Doha Round.http://deepblue.lib.umich.edu/bitstream/2027.42/39857/3/wp472.pd

Everything you always wanted to know about wto accession (but were afraid to ask)

In this paper, the authors explore the complex, long, and unique process of accession to the World Trade Organization, with its intertwined economic, legal, and political dimensions. Referring to country case studies and sector-specific issues, the paper organizes some of the current reflections on the topic around three main themes. First, it explores the rationale of accession to the World Trade Organization: Why would new members join the WTO? And why would incumbent members let new members in? Second, it analyzes the World Trade Organization accession process in detail: What are the main characteristics and challenges of the accession process? Has it evolved over time, and how? Third, the paper looks at the implementation of World Trade Organization accession deals: Is accession the end or the beginning of the story? What are the implications for the participating countries and the multilateral trading system?World Trade Organization,Economic Theory&Research,Trade and Services,Trade Law,Debt Markets

SOLACE: A framework for electronic negotiations

Copyright @ 2011 Walter de Gruyter GmbHMost existing frameworks for electronic negotiations today are tied to specific negotiation systems for which they were developed, preventing them from being applied to other negotiation scenarios. Thus, the evaluation of electronic negotiation systems is difficult as each one is based on a different framework. Additionally, each developer has to design a new framework for any system to be developed, leading to a ‘reinvention of the wheel’. This paper presents SOLACE—a generic framework for multi-issue negotiations, which can be applied to a variety of negotiation scenarios. In contrast with other frameworks for electronic negotiations, SOLACE supports hybrid systems in which the negotiation participants can be humans, agents or a combination of the two. By recognizing the importance of strategies in negotiations and incorporating a time attribute in negotiation proposals, SOLACE enhances existing approaches and provides a foundation for the flexible electronic negotiation systems of the future
