Since most agricultural programs employ two or more policy instruments simultaneously, it is notable thai little research has attempted to find optimal instrument combinations and no research exists which evaluates the social costs (unrealized benefits) of combining instruments suboptimally. In our paper we report a simple and feasible method to find optimal policy instrument combinations, and we provide the first general, formal approach to measuring the social costs of suboptimal policy instrument combinations. Our approach is illustrated in an analysis for live major U.S. crops (corn, feed grains, wheat, rice, cotton). The simple model we employ for the illustration suggests that except lor the feed grains program, the observed programs combined policy instruments quite suboptimally. We conclude that agricultural economics research now can and should begin placing increased emphasis on studying optimal policy instrument combinations. 相似文献

Is the Risk of Bankruptcy a Systematic Risk? 总被引:6,自引:0,他引:6
Ilia D. Dichev 《The Journal of Finance》1998,53(3):1131-1147
Several studies suggest that a firm distress risk factor could be behind the size and the book-to-market effects. A natural proxy for firm distress is bankruptcy risk. If bankruptcy risk is systematic, one would expect a positive association between bankruptcy risk and subsequent realized returns. However, results demonstrate that bankruptcy risk is not rewarded by higher returns. Thus, a distress factor is unlikely to account for the size and book-to-market effects. Surprisingly, firms with high bankruptcy risk earn lower than average returns since 1980. A risk-based explanation cannot fully explain the anomalous evidence. 相似文献

The objective of this study is to discuss the rehabilitation of patients in primary health care with problems in the musculoskeletal system from a socioeconomic perspective. A trial with coordinated rehabilitation in primary health care is compared with traditional rehabilitation. This trial, performed in Sweden in 1994, was a two-year prospective and comparative study of consecutively included patients with long-term illnesses due musculoskeletal problems (810 observations). A cost-utility analysis shows that the new rehabilitation program in primary health care is a cost-minimization program for society. There is no significant difference in the quality of life between the trial and control groups. The total cost is lower for rehabilitation in primary health care than for traditional rehabilitation (6 percent). The indirect costs are higher than the direct health care costs (60 percent), and payments from social insurance increased by 8 percent. The health economic results support rehabilitation in primary health care but also points out that this type of rehabilitation can be further improved. 相似文献

The paper examines methodological and subject aspects of some problem questions that arise in organizing and technologization a long-term forecast procedure. It looks at the basic elements of the methodology and technique of a long-term forecast performed during the development of the Concept for Long-term Socioeconomic Development of the Russian Federation. Key conditions for technology application in the framework of two possible scenarios of Russian economic growth, primary-and-energy and innovation-active, are analyzed. 相似文献
