In 2015, the Federal Communications Commission (FCC) imposed common carriage regulation—so-called Title II requirements—on previously unregulated broadband Internet service providers. The regime shift was premised on the FCC’s findings that such rules had demonstrably yielded economic gains. This paper evaluates the FCC’s empirical arguments and finds them uncompelling. Adjustments for inflation or general economic trends eliminate the effects cited by the FCC. Moreover, contrary to the Commission’s assessment, mobile services and broadband markets have shown notable growth in response to deregulatory events that reduce Title II requirements. 相似文献

Financial markets, such as the global foreign exchange (FX) market, often exhibit trending behaviour. Within such trends, the market level oscillates with changes in market consensus. Continued oscillations of this type result in the formation of wave patterns within the underlying trend known as channels, which are used by technical analysts as trade entry signals. A sample space of such channels has been constructed from a set of US dollar/British pound Spot FX tick data from 1989–1997 using pattern recognition algorithms and the profitability of trading using such patterns has been estimated. A number of attributes of the resulting collection of channels has been subjected to statistical analysis with the aim of classifying patterns that can be traded profitably using a number of simple trading rules. Results of this analysis show that there exist statistically significant links between the channels' attributes and profitability. 相似文献

Climate change is an externality problem—so the challenges that arise in limiting it and dealing with the effects that remain are largely fiscal. The structure of the problem, however, and the uncertainty which surrounds it, make the design of proper policy responses particularly complex. This paper provides a primer on the fiscal implications of climate change, the aim being to provide a (reasonably) quick and comprehensive overview of the main analytical issues and lessons learned. 相似文献

Investors have been shown to have particular preferences when it comes to the characteristics of stock they hold in their portfolios, while prior gains and losses have been shown to impact on individuals’ economic decisions, both in an investment context and more widely. This paper is the first to investigate how prior gains and losses affect investors’ preferences for particular stock characteristics and so shape their portfolio compositions. Using a rich dataset combination from China, we conclude that prior realized outcomes play an important role in shaping portfolio composition through their impact on the characteristics of stocks that investors choose to hold. We find that positive prior realized outcomes encourage investors to select stocks with a variety of characteristics broadly consistent with higher risk taking (for example, higher betas and higher levels of idiosyncratic risk), though there are some differences across investor classes. While our empirical results are in line with what one would expect from the existing literature on the disposition and house money effects, we also consider other possible interpretations of the results. 相似文献

Recent advances in genetic technology and progress in the multinational Human Genome Project are providing scientists with the ability to look into and manipulate the very makeup of life: the DNA molecule. We can already examine many dozens of plant and animal genes for disease producing abnormalities. In the near future, we will have the ability to alter specific genes in living tissue. This genetic technology holds great promise in our quest for preventing, diagnosing, treating, and predicting disease, not just in humans, but in all forms of life. But there are some problems. Philosophically many are not ready for the implications of this technology. There are social and ethical issues that have not been well addressed, and which have, in part, resulted in an unprecedented amount of legislative activity over the past four years aimed at restricting access to and use of genetic information. The ability of the U.S. insurance industry to risk-select may be severely hampered if these restrictions are widely applied. 相似文献

Abstract This paper presents a model for examining the effect of various relationships between mortality rates and lapse rates on the mortality experience of a cohort of insured lives. The approach is individual rather than the aggregate traditionally used in analyzing selective lapsation. The model assumes that insured lives are healthy at policy issue, but later may move to an impaired state from which the lapse rate is zero. Associated with each insured is an unobservable “risk level” random variable, which reflects the heterogeneity of the insured group. Individual mortality and lapse rates are functions of the risk level. A numerical illustration provides some interesting results obtained by using this model. 相似文献

Not having access to mainstream financial services, such as a bank account or a credit card, can lead to a variety of social and economic exclusions. In a number of countries, particularly Ireland, Spain, Canada and the UK, credit unions— member-owned financial co-operatives—play a significant role in reaching under-served and excluded communities, as well as providing ‘safe’ avenues for savings and credit. Yet many credit unions are facing financial and operational problems. This article looks at the experience of Welsh credit unions. The research has implications for policy development and government–credit union relations in Wales and further research on credit unions and financial inclusion. 相似文献

In 1882 new statutes were prepared for the University and colleges of Oxford. This paper looks at the legislative developments leading up to these changes, and by examining the case of Magdalen College shows how these external pressures led to the replacement of charge and discharge accounting by double entry bookkeeping and the appointment of external auditors. 相似文献

By using new and unusual data sets for large samples of firms in Estonia, Latvia and Lithuania we find that, since privatization, diverse patterns of enterprise ownership have emerged and ownership configurations are quite dynamic. To test competing theories on the productivity effects of alternative ownership structures, identical cross sectional production functions specifications are estimated for each country for varying years during 1993 1996. While the effects of private ownership upon productivity are found to vary considerably over time and across countries, productivity effects are always found to be either zero or positive, thus providing partial support for the hypothesis that state ownership is less efficient than private ownership. Findings are mixed concerning hypotheses on the effects of particular ownership structures. Often (e.g. for Lithuania) estimates indicate that all forms of private ownership have zero productivity effects. However, some estimates for Estonia provide support for the mainstream hypothesis that outside (and especially foreign) ownership is preferred to insider ownership. But in other estimates (again for Estonia) majority ownership by employees is found to deliver better business performance than majority ownership by managers (thus refuting the hypothesis that the preferred form of insider ownership is ownership by managers). 相似文献
