In 1991 the FCC implemented a price cap plan for local exchange carriers' interstate access service designed to deal with the regulatory boundaries problem arising from the breakup of AT&T in 1984. The experience with the price cap plan demonstrates the difficulty of predicting productivity growth accurately and makes clear that regulators cannot depend upon a pure price cap plan to keep prices within a reasonable range of costs. With periodic reviews to readjust plan parameters, however, a price cap plan can maintain the rate-of-return close to the target rate-of-return without diminishing the price cap plan's incentives for efficient production. A simple method of recalculating the X-factor based on the rate-of-return over the previous three years worked well in simulations. If this procedure had been used over the price cap period 1991 to 2000, prices would have been 20 percent lower and expenditures on LECs' telecommunications service subject to a price cap would have been $3.8 billion lower.  相似文献

This article asks why, in contrast to other historic territories with a regional language, such as Catalonia and the Basque Country, nationalist parties in the Autonomous Community of Galicia receive less electoral support. Going beyond prior explanations of this counterintuitive political outcome, which were mainly based on economic, sociological, and institutional factors, this piece of research sheds light on the strategies of political parties. It examines not only nationalist forces but statewide ones that successfully compete in Galicia. Our analysis is focused on the Bloque Nacionalista Galego (BNG) because this is the only nationalist force that has consistently achieved representation within the regional Parliament. Along with BNG's translation into party positions in both the left-right and center-periphery dimensions, the article's main contribution is its updating of the BNG's three framing strategies: the nationalism/“Spanishism” (1982–1993), the “common project” discourse (1993–2005), and the sovereigntist one (2005 onward). Shifts in public opinion regarding the territorial model and other attitudes toward self-government are also examined.  相似文献

The competing merits of plurality and proportional representation have intrigued political economists and political scientists for quite some time. Of primary interest is whether one or the other system is better in serving the interests of the electorate. Since theoreticians are unable to unambiguously determine the answer to this question, the issue must ultimately be decided empirically. We use data from Sicilian elections, where the system was recently altered towards the system of plurality. We are able to demonstrate that the proportional representation system engenders greater information among voters and elicits greater commitment from them than plurality. We are also able to show that in larger towns increased information causes a more dispersed vote under a proportional representation system; further, this result does not hold under plurality. This may have some implications for the size of positional rents reaped by political parties under the two electoral systems.  相似文献

The vast natural resources of India's forests, including non-timber forest products (NTFPs), such as medicinal and aromatic plants, leaves, fruits, seeds, resins, gums, bamboos, and canes, offer employment that provides up to half the income of about 25 per cent of the country's rural labour force. However, poor harvesting practices and over-exploitation in the face of increasing market demand are threatening the sustainability of these resources, and thus the livelihoods of forest-dependent tribal communities. This article analyses the role of NTFPs in livelihoods-improvement initiatives and considers recent initiatives intended to enhance their conservation and sustainable management. It recommends policies to optimise the potential of NTFPs, both to support rural livelihoods and to contribute to India's social, economic, and environmental well-being.  相似文献

While scholars have tended to focus on domestic factors as most critical to the consolidation of democracy, the post-communist European Union (EU) candidate states have exhibited a unique confluence of domestic and foreign policies, due to their objective of EU membership. This article assesses and compares the impact of the EU on policy making in two diverse candidate states in their first decade of transition, focusing on minority rights protection as a fundamental requirement of both EU membership and a stable democracy. I find that the EU has played a principal role in the reform process and democratic consolidation of candidate states, even in the controversial field of minority rights. The degree and nature of the EU’s impact, however, has depended in part on the activism of the particular minority, EU interest and pressure, EU Member States’ own domestic policies, and the persistence of racism in society. Dr. Melanie H. Ram is a research associate at the Institute for European, Russian and Eurasian Studies at George Washington University and Senior Program Officer for the Japan International Cooperation Agency USA Office. She has written extensively on European Union enlargement and democratic consolidation and reform in Central and Southeastern Europe, and is the author most recently of “Harmonizing Laws with the European Union: The Case of Intellectual Property Rights in the Czech Republic” inNorms and Nannies: The Impact of European Organizations on Central and East European States (2002). Earlier versions of this article were presented at the American Political Science Association Annual Meeting, 30 August–2 September 2001, San Francisco, CA and at “Voice or Exit: Comparative Perspectives on Ethnic Minorities in Twentieth Century Europe,” Humboldt University, Berlin, 14–16 June 2001.  相似文献

Existing research highlights that families face geographic, social, and psychological constraints that may limit the extent to which competition can take hold in school choice programs. In this paper, we address the implications of such findings by creating a network of student flows from 11 cohorts of eighth‐grade students in the Chicago Public Schools (CPS). We applied a custom algorithm to group together schools with similar sending and receiving patterns, and calculated the difference in mean achievement between a student's attended and assigned high schools. For all identified school groupings, we found that the students were on average moving to higher achieving schools. We also found that the movement toward higher achieving schools of the top achievement quartile of students was over twice as large as that of the bottom quartile, but that the flows of both the highest and lowest achieving student quartiles were toward higher achieving destinations. Our results suggest that student movements in CPS between the years of 2001 to 2005 were consistent with creating market pressure for improvement as well as increasing segregation by achievement. However, further research into how schools responded to those movements is required to make inferences about the level or consequences of competition generated by choice‐related reforms during that time.  相似文献

This report assesses conditions that contribute to or are potentially hospitable to transnational criminal activity and terrorist activity in selected regions of the world during the period 1999–2002. Although the focus of the report is on transnational activity, domestic criminal activity is recognized as a key foundation for transnational crime, especially as the forces of globalization intensify. The report has been arranged geographically into the following major headings: Africa, the former Soviet Union and Eastern Europe, South Asia, Southeast Asia, Western Europe, and the Western Hemisphere. Within the geographical headings, the report addresses individual countries with particularly salient conditions. Cases such as the Triborder Area (TBA) of South America and East and West Africa, where conditions largely overlap national borders, have been treated as regions rather than by imposing an artificial delineation by country. The bibliography has been divided into the same geographical headings as the text. The major sources for this report are recent periodical reports from Western and regional sources, Internet sites offering credible recent information, selected recent monographs, and personal communications with regional experts. Treatment of individual countries varies according to the extent and seriousness of conditions under study. Thus some countries in a region are not discussed, and others are discussed only from the perspective of one or two pertinent activities or conditions. Because they border the United States, Canada and Mexico have received especially extensive treatment.  相似文献
