Valuing EQ-5D health states: A review and analysis, CHERE Working Paper 2007/9
Objective: To identify the key methodological issues in the construction of population-level EQ-5D / Time Trade-Off (TTO) preference elicitation studies. Study Design: This study involves three components. The first was to identify existing population-level EQ-5D TTO studies. The second was to illustrate and discuss the key areas of divergence between studies, including the international comparison of tariffs. The third was to portray the relative merits of each of the approaches, and to compare the results of studies across countries. Results: While most papers report use of the protocol developed in the original UK study, we identified three key areas of divergence in the construction and analysis of surveys. These are the number of health states valued in order to determine the algorithm for estimating all health states, the approach to valuing states worse than immediate death, and the choice of algorithm. Finally, the evidence on international comparisons suggests differences between countries, although it is difficult to disentangle differences in cultural attitudes with random error and differences due to methodological divergence. Conclusion: Differences in methods are likely to obscure true differences in values between countries. However, population-specific valuation sets for countries engaging in economic evaluation would better represent societal attitudes.health state valuation, EQ5-D

Afghanistan: Challenges and Options for Reconstructing a Stable and Moderate State
This report provides information on and analysis of the current situation in Afghanistan, taking into consideration the country’s essential characteristics and political developments since about the time of the overthrow of the last Afghan King, Zahir Shah, in 1973, and sketches out four possible scenarios for Afghanistan’s future. Finally, the report identifies and analyzes factors that will influence Afghanistan’s political future, and discusses three policy areas in particular in which actions by the United States could be crucial to the achievement of the U.S. goal of a peaceful, stable, democratic, and terrorist-free Afghanistan.

Asian Financial Crisis: An Analysis of U.S. Foreign Policy Interests and Options
The principal focus of this report is on the foreign policy ramifications of the Asian financial crisis and U.S. options for addressing them. This report tracks and analyzes the efforts of the most seriously affected Asian countries to deal with their economic and financial problems, and their interaction with the International Monetary Fund (IMF), the United States, and other major sources of financial support and policy advice. It also addresses the implications of the crisis for such U.S. interests as regional stability and the prevention of conflict, trade liberalization, and U.S. regional and global leadership, and discusses the principal factors that could influence the duration and severity of the crisis. A final section considers options for Congress in the context of various criticisms of the IMF’s stabilization programs and the operations of the Fund itself
