When the telecommunications industry was liberalised in Europe and North America in the 1980s and 1990s, it inherited a legacy of monopoly providers whose footprint was national or multi-regional in its character. The regulatory framework, particularly that adopted in EU member states, reflected this pattern of relatively homogeneous deployment achieved, in part, by decades of cross-subsidised pricing and universal service goals. Perhaps because of this legacy, telecommunications regulators have often adopted the presumption that relevant markets are national in character, unless proven otherwise Although geographically-variegated regulatory remedies have been permitted (even in the face of allegedly national relevant markets) and adopted in many member states, many regulators have never done so, and overly cautious thresholds for permitting geographically based forbearance suggest a continued bias towards presuming national markets and remedies. We find that this presumption of uniformity and the tendency to aggregate geographic markets together is not supported by first principles of antitrust analysis, although there may have been strong practical reasons to apply this presumption in the past circumstances of the telecommunications and broadband industries.On the ground, however, there has arguably never been as much heterogeneity across geographies and across technological solutions that provide effective ultra-fast broadband speeds. Both technological (i.e., product market) and geographic heterogeneity are likely to increase with the advent of mobile 5G networks. With their deployment, a cautious regulatory stance towards geographic variation and a cautious regulatory stance towards inter-technology or inter-modal competition may result in regulation that could exceed what is required to ensure effective competition and could instead distort the incentives to enter of facilities-based actors. This may also result in higher-cost and inefficient investment. A more geographically varied and technologically agnostic regulatory framework may satisfy the principle of proportionate and focused regulation—with the possibility that the locus of regulation shifts from the access network to bottleneck facilities such as fibre, ducts and poles.This discussion is especially germane when one considers the highly speculative nature of forecasts and projections about future demand, and the competing claims of proponents of 5G and fibre. While there is some scepticism about the performance of mobile networks, we note that pure mobile and fixed 5G services may have synergies in deployment, and that the idea of competing with residential broadband services is a core strategy of very influential large-scale industry actors. In terms of a future research agenda, regulatory decisions could benefit from much more research into the relationship between domestic and global bandwidth constraints and their influence on development of software and application, as well as much more quantitative research by academics on the drivers of bandwidth demand. The risks associated with promoting investment that results in large-scale wasted resources should also be central to the regulatory agenda. 相似文献

This paper proposes a typology for provider roles in defining business services. The starting point of the study is the underlying rationale of much of the service purchasing literature that buyers have or can easily access the necessary know-how to procure business services. If this does not hold, the implication is that buying firms would shy away from buying complex services. An alternative perspective recognizes that purchasing business services requires its own set of sourcing capabilities, which may be lacking. Buying firms may have limited know-how in terms of defining and articulating their requirements or not be fully aware of them in the first place. However, the buyer's lack of sourcing capabilities need not be an injunction to internalize the service. In these circumstances, service providers step in, help buying firms specify their requirements and play a key role in defining what is procured and how. We build on this interactive view of service definition to undertake a comparative case analysis of four business service contracting situations arrayed along two dimensions — buyer perceived uncertainty and provider's buyer-specific experience. We conclude that service providers play different roles in each case. These are classified as translating, re-engineering, developing, and fine-tuning roles. 相似文献

In this paper, I develop a New Keynesian model that embeds heterogeneous workers with asymmetric wage adjustment costs to address two inflation puzzles: missing deflation during the Great Recession and the subsequent missing inflation. When the wage adjustment costs are estimated according to U.S. microwage data, downward nominal wage rigidity emerges, which flattens the observed price Phillips curve during and after recessions. Endogenous evolution of the cross-sectional wage distribution generates nonlinear dynamics including the sign, size, and state dependence. These nonlinearities enable the model to address the inflation puzzles as well as matching microevidence on wage adjustments. 相似文献

从实际案例可以看出,《公司法司法解释二》虽对《公司法》作了较好补充,但在公司司法解散诉讼中还需准确把握好如下问题:需要对“经营管理严重困难”和“股东利益受到重大损失”进行准确的司法界定;准确理解“通过其他途径不能解决”的内涵;解决好与诉讼有关的程序问题和司法解散后的清算问题。 相似文献

The Fijian government's response since 2010 to the loss of preferential access to the European Union's previously highly protected sugar market has been to increasingly support its cane growers and millers. That support is now much higher than most other countries' assistance to the sugar industry. This study provides detailed estimates of the changing extent of those transfers to producers from both taxpayers and consumers during 2010–22. In doing so, it estimates for the first time an annual time series of nominal rates of assistance to producers and consumer tax equivalent rates (NRAs and CTEs, but they are also converted to producer and consumer support estimates as defined by the OECD). Those NRA and CTE estimates have been approaching 100%. The level of support was equivalent to 10% of Fiji's agricultural value added in 2018–21 and is around 5% of its government's consolidated revenue—at a time when the government has a very high debt-to-GDP ratio (90% in 2022). Since the nature of the support is economically inefficient, inequitable, environmentally damaging and fiscally unsustainable given foreseeable market prospects, suggestions are made as to how that support might be repurposed to provide better economic, social and environmental outcomes for Fiji. 相似文献

Over recent decades hospitality research has made considerable advancements and contributions to knowledge creation. However, a review of associated literature reveals that there exists a significant degree of debate concerning the definitional, philosophical and conceptual dimensions of hospitality. This paper aims to capture current thinking and key challenges confronting the research community. Conclusions are drawn calling for: definitional precision of hospitality; a clearly articulated research philosophy locating hospitality as a specialist field of study within the social science landscape; an enhanced degree of research philosophy awareness by researchers; and the benefits of formulating and agreeing an internally valid conceptual framework.
