ABSTRACT: Federal planners, in proposing the massive main stem Missouri River water developments in Montana and North Dakota, promised economic and social benefits to the local residents. Five main stem dams, Fort Peck, Garrison, Oahe, Big Bend and Fort Randall, were evaluated for community and rural development effectiveness. Thirty-seven development factors were examined and improvements noted. Only small differences were noted between areas with water developments and the control area. Further analysis revealed that water development benefits moved downstream and to existing urban areas. The Missouri River's rural areas and small communities were not developed significantly by the water projects. Several problems associated with water development policy were illustrated by the study. Cultural differences between planners and the population impacted were ignored. Second, the allocation of social costs was not considered and related to this, serious geographic maldistribution of benefits and costs resulted. The differences between pre-development promises and development performance was dramatic. While the large dams remain as landmarks to engineering prowess, the projects need to be evaluated for their success in meeting humanistic development objectives. Major redevelopment may be warranted by such an ex-post evaluation. 相似文献

Increased use of renewable energy is one of several promising methods for reducing emissions of local, regional, and global air pollutants, including greenhouse gas emissions associated with fossil-fuel based electricity production. Among the available options for encouraging renewable electricity generation, the renewables portfolio standard (RPS) has become especially popular in recent years. The RPS is a newly established policy mechanism, however, and experience with its use has not been widely documented and evaluated. This paper describes and evaluates the design, impacts, and early experience of 13 U.S. state RPS policies. These 13 policies share a common goal of encouraging renewable energy supply, but each specific RPS is designed differently. Our evaluation shows both successes and failures with this policy mechanism; some state RPS policies are positively impacting renewable energy development, while others have been poorly designed and will do little to advance renewable energy markets.We emphasize the importance of policy design details, and specifically highlight critical design pitfalls that have been commonly experienced. Though experience with the RPS is still limited, we have now gained some knowledge of the conditions and design features necessary to make an RPS policy work. An important objective of this article is therefore to identify and describe broad policy design principles and specific best practice design elements that might be used to guide the design of future renewables portfolio standards. 相似文献

Sectoral analysis, a new branch of political science, alleges that mineral extraction creates a socio-political climate that promotes inflexible statism, which in turn leads to substandard development performance. The theory, that mineral economies underperform bureaucratically and economically, is said not only to hold in a post-dictive sense for the mature mineral economies, such as Zambia, but also in a predictive sense for the newer mineral economies, such as Ecuador. This essay reviews and assesses this hypothesis in the light of the empirical evidence comparing mineral production, state capacity, and economic performance. It finds that the sectoralist view is supportable only in selected cases, and is not a general result. 相似文献

This paper presents a new market-incentive (MI) system to recycle waste-packaging containers in Taiwan. Since most used packaging containers have no or insufficient market value, the government imposes a combined product charge and subsidy policy to provide enough economic incentive for recycling various kinds of packaging containers, such as iron, aluminum, paper, glass and plastic. Empirical results show that the new MI approach has stimulated and established the recycling market for waste-packaging containers. The new recycling system has provided 18,356 employment opportunities and generated NT$ 6.97 billion in real-production value and NT$ 3.18 billion in real GDP during the 1998 survey year. Cost-effectiveness analysis constitutes the theoretical foundation of the new scheme, whereas data used to compute empirical product charge are from two sources: marketing surveys of internal conventional costs of solid-waste collection, disposal and recycling in Taiwan, and benefit transfer of external environmental costs in the United States. The new recycling policy designed by the authors provides a reasonable solution for solid-waste management in a country with limited land resources such as Taiwan. 相似文献
