This paper examines the effects of introducing competition into monopolized network industries on prices and infrastructure
quality. Analyzing a model with reduced-form demand, we first show that deregulating an integrated monopoly cannot simultaneously
decrease the retail price and increase infrastructure quality. Second, we derive conditions under which reducing both retail
price and infrastructure quality relative to the integrated monopoly outcome increases welfare. Third, we argue that restructuring
and setting very low access charges may yield welfare losses, as infrastructure investment is undermined. We provide an extensive
analysis of the linear demand model and discuss policy implications. 相似文献

Property rights protection and access to bank loans 总被引:1,自引:0,他引:1
Poor protection of private property has limited the access to bank loans by private enterprises in developing and transition economies. Under those circumstances, private entrepreneurs have resorted to various ways of enhancing the de facto protection of private property. Using a dataset of 3,073 private enterprises in China, this paper empirically investigates the impact of political participation and philanthropic activities – informal substitutes for the lack of formal protection of private property – on the access to bank loans. 相似文献

We compare various access pricing rules in the two-way access model. We show that the Generalized Efficient Component Pricing
Rule (TECPR) leads to a lower equilibrium price than does the Efficient Component Pricing Rule, (ECPR) marginal cost pricing,
(MCP) and any non-negative fixed access charges.

This paper reports the results of the quantitative analysis of international experience of the relationship between infrastructure investment in the deployment of capacity that can carry large volumes of voice and data traffic and regulatory policy changes in the telecommunications sectors. It looks at the relationship between infrastructure investment for these infrastructure assets and the access pricing régimes for local exchange carriers in the United States and Europe. It then looks at the relationship between various aspects of regulatory and institutional policy changes in Europe and how they affect access prices.The paper finds that a lower access price promotes greater deployment of digital technology among US incumbent local exchange carriers (ILECs). Based on this finding, it suggests that it is in the ILECs interest to have access to their networks encouraged.The European data for interconnection are recent and far reaching conclusions are not feasible, but the findings, however, suggest that competition has worked by facilitating new entry through decreasing interconnection prices, although path dependencies, of existing and traditional concepts, in the mindsets of operators as well as regulators, may account for these findings. 相似文献

Information and communications technologies have become an integral part of life in an information society, affecting employment, education and many other daily activities. For individuals with disabilities, equal access to telecommunications remains a concern, as many technologies that are developed do not allow for equal access. Law and policy have made significant progress in some nations, but sizeable barriers remain to the social inclusion of individuals with disabilities in telecommunications technologies and services. This paper examines the importance of equal access to telecommunications for individuals with disabilities in both the formulation and the implementation of policy. Analyzing issues of policy and implementation, this paper discusses policy questions and potential areas of research to better understand the relationship of telecommunications policy to access for persons with disabilities. 相似文献

In the 1990s, the Democratic People’s Republic of Korea (North Korea) suffered from severe food shortages and large-scale deforestation, which triggered a stage of rural conservation reform. Since 2004, with support from the Swiss Agency for Development and Cooperation (SDC), North Korea’s Ministry of Land and Environmental Protection (MoLEP) has implemented a Sloping Land Management Program (SLMP). The SLMP established sloping land user groups and granted these groups the right to use marginal land for agroforestry development. This devolution of land rights from state control onto local groups is a landmark in North Korea, and this decentralization initiative has now expanded to over eight counties to involve thousands of households. It has also led to the launch of a National Agroforestry Policy and Strategy. Drawing from both qualitative and quantitative data collected from 2008 to 2014, this paper documents the process and effects of the SLMP. It argues that the decentralization reform in land management has contributed to not only food security with increased food crop diversity and productivity, but also notably forest recovery through an expansion of tree plantations and agroforestry practices on degraded sloping lands. However, an insufficient power transfer in the form of a lack of timber rights granted to the local user groups has hampered the effectiveness of the SLMP. There are also institutional and geopolitical challenges that are limiting further scaling-up of land-use decentralization across the country. The policy implication calls for more international investment as well as national land-use policy reforms in order to promote and facilitate further decentralization of sloping land management and to secure greater use rights for sloping land user groups. 相似文献
