We generalize and extend the sequential model proposed by the resources and appropriation theory to explain the digital divide in the European Union plus the United Kingdom (EU27+UK). We measure the theoretical constructs of the model with data provided by the EU and test the theoretical predictions using a partial least squares structural equation model. We find support for the hypothesized relationships but find that the effects vary depending on the digital development level of countries. While education overall is the primary determinant of the social production of digital inequalities, a country's digital development level is crucial for less well-educated Europeans. These findings have theoretical and practical implications: (1) they call into question the homogeneity of the effect of causal relationships and the assumption that individuals differ only in terms of motivation, access, and digital skills, and (2) they indicate that socially disadvantaged Europeans benefit from living in more digitally developed countries. 相似文献

Open access resources are frequently not managed efficiently, resulting in falling stock levels and a declining income for fishermen. In the late 1970's, the policy response to this problem was the implementation of 200-mile fishing zones, which enabled the European Union to formulate and implement the Common Fisheries Policy, aimed at (among other things) conservation and distribution of available stocks. In Germany, this shift from an open access regime towards a common property regime had favourable outcomes. The trend of falling prices was reversed. The conclusion was that intertemporal efficiency had increased as a result of (inter)governmental policy. Apparently, a wedge was formed between price and marginal harvesting costs, implying that scarcity rent had returned as a component of prices. 相似文献

This paper analyzes vertical restraints in relation to market access issues. In Section II we briefly review the recent three major trade conflicts between Japan and the USA in light of vertical restraints. In Section III we review the major policy lessons of the economics literature of vertical restraints, and analyze whether we need a special treatment for vertical restraints abroad for a market access reason. In Section IV we evaluate the policy options towards foreign foreclosure and suggest that nondiscriminatory application of foreign or home competition policy should be the mechanism to address such concern instead of trade policy actions such as voluntary import expansions. 相似文献

本文着眼于澳大利亚在治理金融衍生品市场内幕交易中积累的丰富经验,针对一个崭新的前瞻性课题,即金融衍生品市场的内幕交易问题展开研究。作者认为,由于内幕交易与信息非对称性之间存在的内在冲突,实际上反内幕交易法规很难有效地阻止金融衍生品的内幕交易行为,过于复杂的反内幕交易法规会对市场产生一些负面影响,而放松内幕交易监管这一新思维将对市场的良性发展更为有益,应该让市场来决定内幕交易行为的“存亡”。但目前最为现实、温和的选择仍然是修改现行反内幕交易法,以维护市场的公平性和有效性。最后,笔者对如何缓解中国目前内幕交易猖獗的现状提出建议。 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

This study assesses the role of ICT in complementing private credit bureaus (PCB) and public credit registries (PCR) in reducing information asymmetry for financial access. The empirical evidence is based on Generalised Method of Moments with 53 African countries for the period 2004–2011. The following findings are established. First on financial access: (i) the marginal effects from interactions between ICT and PCR (PCB) are consistently positive (negative); (ii) net effects from interactions are negative with the higher magnitude from PCR and (iii) only thresholds corresponding to interactions between PCR and internet penetration are within range. Second, findings on financial allocation efficiency reveal positive marginal and net effects exclusively for mobile phones and PCR. Third, allocation efficiency may be constrained by increasing financial deposits. Overall, the complementarity between information offices and ICT in boosting financial access is still very limited. Policy implications are discussed with emphasis on improving the engaged complementarity and fighting surplus liquidity. 相似文献

UxDMA算法是一种高效的集中式算法,是用于时分多址、频分多址和码分多址信道分配的统一算法。在UxDMA的基础上,利用多波束天线的多波束形成能力,针对低时延定向ad hoc网络提出了一种集中式调度算法——CLSM(Centralized Low-delay Scheduling Algorithm Based on Multi-beam Antennas)。CLSM通过不同时延等级限制的报文来比较着色后发送链路的优先级,优先选择高优先级链路传输。通过仿真验证了CLSM的性能:与UxDMA相比,该算法在多时延限制的发送端调度中表现出了更好的吞吐量和时延性能。 相似文献
