A number of recent international situations have raised again questions regarding the usefulness of economic sanctions as an instrument of foreign policy. Sanctions continue to be applied in a variety of contexts, yet we have not developed a sufficient understanding of the processes involved to determine when, or even if, sanctions can "work." While a great deal has been written on the subject, there have been neither attempts to subject the theoretical arguments to empirical testing nor efforts to provide systematic theoretical explanations for the empirical results that have been produced. In this article, we attempt to address this shortcoming in the literature. We propose a theory of sanctions effectiveness that is based on the spatial model of bargaining in international crises and use this theory to derive a number of hypotheses regarding when sanctions should produce favorable policy outcomes. We then subject some of the derived hypotheses to an empirical test based on a large number of international disputes. The model suggests that while sanctions will not work in many cases, they can have a slight effect on the distribution of expected outcomes if the costs of the sanctions are sufficiently high relative to the values at stake. The available evidence appears to support these expectations. 相似文献

The achievement of economic growth and social equity in developing nations, whatever path they pursue, has been hampered by uncertainty, instability, and uncontrollability in budgeting. It appears likely that left to themselves, these budget systems will continue largely unchanged, with little or no progress toward eliminating poverty and advancing development. However, several options are available for restructuring budget systems through implementation of carefully devised systematic action plans. 相似文献

Multiple-item measures of self-reported offending typically provide the principal outcome measures for individual level research on the causes of crime and deviance. This article directs attention to the substantial problems presented by the task of forming composite scores for these measures, and it presents a possible solution to those problems. We consider scaling by means of the graded response model from item response theory (IRT) as a potential means of overcoming the shortcomings of traditional summative scaling and of obtaining valuable information about the strengths and weaknesses of our measures. We illustrate this strategy through a scale analysis of a fourteen-item, self-report measure of delinquency, using three years of data from the Monitoring the Future study, an annual national survey of high school seniors. The graded response model proves to be consistent with the data, and it provides results that address important substantive questions about self-report measures. The findings are informative about the strengths and weaknesses of alternative strategies for developing self-report instruments, indicating that there is little to be gained by making fine distinctions in the frequency of individual delinquent acts. 相似文献
