The paper attempts to identify the telecom-sector performance indicators, relevant economic variables, and institutional characteristics
of a country that effect the process of privatization of state-owned telecom enterprises. Using standard duration analysis
of a panel data, we demonstrate that the privatization incentives are not only shaped by the mobility of financial capital
in a country but are also influenced by the degree of competitiveness of private sector participation in policy-making process.
The empirical results also reveal the significant impact of productive efficiency in telecom service provision on its course
to privatization.
We thank an anonymous referee for helpful comments and suggestions. We are solely responsible for all mistakes. 相似文献

This study extends the great fish war model of Levhari and Mirman [Levhari, D. and Mirman, L. (1980) Bell Journal of Economics 11: 322–344] by incorporating a multiple country context into the model and investigates the existence of a partial coordination
Nash equilibrium. First, findings of this paper suggest that a partial coordination scheme is sustainable only in limited
cases. Any coalition that has more than two member countries cannot be sustained. Second, the existence and the number of
coordinating countries depend critically on the magnitude of the biological and preference parameters. Finally, if the coalition
is assumed to be a dominant player, there always exist one or two welfare-improving sustainable coalitions and the size of
the sustainable coalitions depends on the parameters of the problem. 相似文献

The multiple objectives of perishable product inventory management are examined in this paper. These objectives include: (1) satisfying demand by carrying sufficient inventories, (2) holding down inventory carrying costs, (3) keeping the amount of product spoilage (outdating) at an acceptable level, and (4) maintaining quality by using the product while it is still fresh, and (5) keeping the cost of rotation low. Some of the above objectives are in conflict. Thus, certain redistribution policies may help attain one or more of these objectives to a greater extent. Redistribution involves the transfer of the product from outlets where demand is low to outlets where demand is high. A goal programming model for solving redistribution problems is presented. An example is provided and sensitivity analysis is performed in order to determine when redistribution is advantageous. Applicability of the model is discussed. 相似文献

宁南旱作农区是我国经济落后的地区.生态环境十分严酷,农民生活十分贫穷。按照西部大开发的战略要求,保护生态,实现社会经济与生态恢复同步发展已成为该地区当前和以后相当长一段时期的主要任务。面对中国小康社会建设目标和农业现代化要求,发展草畜一体化生态经济农业将是该地区经济发展的战略选择,以草畜产业为基础的生态经济农业必将成为干旱半干旱地区可持续发展的主要途径。 相似文献

目的 寻找农业水土资源耦合研究热点、梳理研究发展历程、统筹和归纳研究体系,明晰未来研究发展方向和突破点,助力农业水土资源可持续利用。方法 文章通过定性与定量研究相结合,借助CiteSpace软件对1992—2022年农业水土资源耦合研究热点、发展历程进行初步分析,之后借助文献归纳法进一步综述研究体系。结果 研究聚焦于农业水土资源利用效率及效用,总体上经历了从土壤理化性质到水土资源优化配置、从小尺度作物种植到大尺度流域治理的发展历程,研究体系由3个研究基本面和6个研究基本点构成,研究基本面分别为水土资源匹配格局、水土资源利用过程、水土资源状态响应,即“格局—过程—响应”的农业水土资源耦合研究体系。结论 水土资源匹配格局方面需进一步明晰水土资源空间分异特征并加强二者物理交互过程和时空变异规律的研究,建议未来聚焦于识别水土资源配置差别并建立实践性的匹配等别标准;水土资源利用过程方面土地利用变化后水文过程响应研究尚待补充,建议未来可深入探索土地利用与水文过程的二元互馈机理;水土资源状态响应方面气候变化下需注意从气象指标入手探究农业生产中水土资源的关系,建议未来加强气候变化背景下低效利用问题的动态监测及预测模拟。 相似文献

The Communications Act of 1934 created a dual review process in which mergers in the communications industry are reviewed by the Federal Communications Commission (FCC) as well as the antitrust authorities. Commentators have criticized dual review not only as costly and redundant, but also as subject to substantive and procedural abuse. The process of clearing the 2011 Comcast–NBC Universal merger provides a useful case study to examine whether such concerns are justified. A review of the empirical context reveals that the FCC intervened even though the relevant markets were not structured in a way that would ordinarily raise anticompetitive concerns. In addition, the FCC was able to use differences between its review process and that used by the Justice Department to extract concessions from the merging parties that had nothing to do with the merger and which were more properly addressed through general rulemaking. Moreover, the use of voluntary commitments also allowed the FCC to avoid subjecting certain aspects of its decision to public comment and immunized it from having to offer a reasoned explanation or subjecting its decision to judicial review. The aftermath of the merger provides an opportunity to assess whether the FCC’s intervention yielded consumer benefits. 相似文献

ABSTRACTOur model relates the variability of stock returns to the variability of consumption velocity and shows that real stock returns tend to co-vary negatively with expected inflation in a period (or regime) of low and stable inflation and to co-vary positively with expected inflation in a period (or regime) of high and volatile inflation. Long-run real stock returns are shown to be positively related to expected inflation. Our empirical results for 20 countries provide consistent support for our propositions, indicating that the standard deviation of the annual inflation rate roughly equal to 10% is the dividing line between negative and positive return-inflation relations. 相似文献

Business to business (B2B) is the fastest growing segment of the explosive growth of e-commerce. The purpose of this study
is to identify internal factors which influence the supplier’s intention to adopt private exchange (PE), a single buyer side
electronic market (EM). This study identified cost, flexibility, delivery, and quality as internal capabilities and investigated
how these four factors influence suppliers’ participation in PE. The results of the study indicate the following: (1) suppliers
do not believe that their capability to produce customized products for customers plays an important role in PE; (2) they
still believe that standardized rather than engineered products would dominate the marketplace; and (3) a contractible factor
like lower price, rather than non-contractible factors including superior flexibility of production capability, fast and reliable
delivery, and quality, plays an important role in the PE. 相似文献
