Exiting Treaties

This Article analyzes the under-explored phenomenon of unilateral exit from international agreements and intergovernmental organizations. Although clauses authorizing denunciation and withdrawal from treaties are pervasive, international legal scholars and international relations theorists have largely ignored them. This Article draws upon new empirical evidence to provide a comprehensive interdisciplinary framework for understanding treaty exit. It examines when and why states abandon their treaty commitments and explains how exit helps to resolve certain theoretical and doctrinal puzzles that have long troubled scholars of international affairs

Trade Agreements: Impact on the U.S. Economy

[Excerpt] The United States is in the process of considering a number of trade agreements. In addition, the 111th Congress may address the issue of trade promotion authority (TPA), which expired on July 1, 2007. These agreements range from bilateral trade agreements with countries that account for meager shares of U.S. trade to multilateral negotiations that could affect large numbers of U.S. workers and businesses. During this process, Congress likely will be presented with an array of data estimating the impact of trade agreements on the economy, or on a particular segment of the economy. An important policy tool that can assist Congress in assessing the value and the impact of trade agreements is represented by sophisticated models of the economy that are capable of simulating changes in economic conditions. These models are particularly helpful in estimating the effects of trade liberalization in such sectors as agriculture and manufacturing where the barriers to trade are identifiable and subject to some quantifiable estimation. Barriers to trade in services, however, are proving to be more difficult to identify and, therefore, to quantify in an economic model. In addition, the models are highly sensitive to the assumptions that are used to establish the parameters of the model and they are hampered by a serious lack of comprehensive data in the services sector. Nevertheless, the models do provide insight into the magnitude of the economic effects that may occur across economic sectors as a result of trade liberalization. These insights are especially helpful in identifying sectors expected to experience the greatest adjustment costs and, therefore, where opposition to trade agreements is likely to occur. This report examines the major features of economic models being used to estimate the effects of trade agreements. It assesses the strengths and weaknesses of the models as an aid in helping Congress evaluate the economic impact of trade agreements on the U.S. economy. In addition, this report identifies and assesses some of the assumptions used in the economic models and how these assumptions affect the data generated by the models. Finally, this report evaluates the implications for Congress of various options it may consider as it assesses trade agreements

A multi-demand negotiation model based on fuzzy rules elicited via psychological experiments

This paper proposes a multi-demand negotiation model that takes the effect of human users’ psychological characteristics into consideration. Specifically, in our model each negotiating agent's preference over its demands can be changed, according to human users’ attitudes to risk, patience and regret, during the course of a negotiation. And the change of preference structures is determined by fuzzy logic rules, which are elicited through our psychological experiments. The applicability of our model is illustrated by using our model to solve a problem of political negotiation between two countries. Moreover, we do lots of theoretical and empirical analyses to reveal some insights into our model. In addition, to compare our model with existing ones, we make a survey on fuzzy logic based negotiation, and discuss the similarities and differences between our negotiation model and various consensus models
