By any measure, the communication sector is important. It isno surprise, then, that the communication sector has attractedthe attention of both policy-makers and economists. In thispaper, we argue that four characteristics of the networks thatdeliver communication services make this area of particularinterest. We analyse the implications of networks' cost structures;the strong complementarity between their components; the demand-sideexternalities that arise from consumption of their services;and the social obligations attached to them. Despite the attentionthat the communication sector has received, many aspects ofcompetition between networks are still poorly understood. Weidentify some of the key issues that will continue to troubleregulators and interest academics. 相似文献

Outgoing Indonesian president Susilo Bambang Yudhoyono's second-term record is creditable, measured against the targets he set himself in 2010, but deficient in key areas: economic reform, infrastructure investment, and anti-corruption. Indonesia's 2009–14 parliament has been active in economic policymaking, and will leave as its legacy a raft of protectionist legislation. Both presidential candidates, Joko ‘Jokowi’ Widodo and Prabowo Subianto, have appealed to nationalism in their campaigns, calling for Indonesia to assert its sovereignty and increase its self-sufficiency, but Jokowi's economic platform is more moderate and economically literate than Prabowo's. The incoming president will inherit an economy that continues to slow. Growth is now not expected to approach 6% until 2015 at the earliest. Having engineered a reduction in the current account deficit, Indonesian policymakers now face the more difficult problem of structural fiscal adjustment. Energy subsidies are the most immediate problem, but fiscal reform more generally will emerge as an overriding and unpleasant imperative for whoever wins the presidential election on 9 July. Unless difficult fiscal policy measures are taken, Indonesia will face major trade-offs between deficit control and investment in social programs and economic infrastructure. The new president will struggle to restrict the deficit to the cap of 3% of GDP: a balanced budget will likely not be feasible for several years. He will need to increase the ratio of revenue to GDP and eliminate fuel subsidies—through a more systematic approach than the infrequent price increases of the past. He will need to choose carefully between competing expenditure priorities, such as infrastructure and defence. The new president would also be well advised to tread cautiously in implementing the legal mandates he will inherit, and to work with parliament to avoid further and unwind current earmarking of public expenditure. 相似文献

Comparing asset swap spreads across bonds is a widely used tool for measuring relative value. This approach leads portfolio managers to increase their risk exposure in ways that are not transparent. Credit default swaps are utilized to demonstrate that viewing wide asset swaps as an indicator of relative value is a mirage. The paper documents the empirical regularities in the term structure of credit spreads and spread volatilities that make this result possible. In addition, we present empirical evidence of the imprint made on corporate bond returns by the widespread use of the asset swaps data. 相似文献

We study the relation between the ownership structure of financial assets and non-fundamental risk. We define an asset to be fragile if it is susceptible to non-fundamental shifts in demand. An asset can be fragile because of concentrated ownership, or because its owners face correlated or volatile liquidity shocks, i.e., they must buy or sell at the same time. We formalize this idea and apply it to mutual fund ownership of US stocks. Consistent with our predictions, fragility strongly predicts price volatility. We then extend the logic of fragility to investigate two natural extensions: (1) the forecast of stock return comovement and (2) the potentially destabilizing impact of arbitrageurs on stock prices. 相似文献

Spatial Autoregression Techniques for Real Estate Data 总被引:8,自引:0,他引:8
This paper describes how spatial techniques can be used to improve the accuracy of market value estimates obtained using multiple regression analysis. Rather than eliminating the problem of spatial residual dependencies through the inclusion of many independent variables, spatial statistical methods typically keep fewer independent variables and augment these with a simple model of the spatial error dependence. We discuss alternative spatial autoregression model specifications, estimation methods, and prediction procedures. An empirical example is provided in the appendix. 相似文献

A comment on ‘A Multidimensional Scale for Measuring Business Ethics: A Purification and Refinement’
This comment is offered in response to Hansen's A Multidimensional Scale for Measuring Business Ethics: A Purification and Refinement. Five issues arising from Hansen's purification and refinement efforts are addressed. These include the issues of parsimony, predictive validity, collinearity, reliability, and what we see as a confusion between normative and positive theory.Dr. R. Eric Reidenbach is Professor of Marketing, and Director of the Center for Business Development and Research at The University of Southern Mississippi. He has written extensively on business and marketing ethics.Dr. Donald P. Robin, Professor of Business Ethics and Professor of Marketing, is coauthor with R. Eric Reidenbach of two recent books on business ethics with Prentice-Hall. He is a frequent lecturer on business ethics and is the author of several articles on the subject. 相似文献

It is a marketplace reality that marketing managers sometimes inflict switching costs on their customers, to inhibit them from defecting to new suppliers. In a competitive setting, such as the Internet market, where competition may be only one click away, has the potential of switching costs as an exit barrier and a binding ingredient of customer loyalty become altered? To address that issue, this article examines the moderating effects of switching costs on customer loyalty through both satisfaction and perceived‐value measures. The results, evoked from a Web‐based survey of online service users, indicate that companies that strive for customer loyalty should focus primarily on satisfaction and perceived value. The moderating effects of switching costs on the association of customer loyalty and customer satisfaction and perceived value are significant only when the level of customer satisfaction or perceived value is above average. In light of the major findings, the article sets forth strategic implications for customer loyalty in the setting of electronic commerce. © 2004 Wiley Periodicals, Inc. 相似文献

As a result of the public demand for higher ethical standards, business schools are increasingly taking ethical matters seriously. But their effort has concentrated on teaching business ethics and on students' ethical behavior. Business faculty, in contrast, has attracted much less attention. This paper explores the context and the implications of an alleged case of plagiarism in a master's dissertation submitted to a university lacking both an ethical code of conduct and a formalized procedure to deal with academic misconduct. The events evolved into a bitter political process in which the more ethically aware members of faculty challenged efforts to cover-up. Here the focus is on the motives and behavior of faculty members involved in this case rather than the alleged plagiarist's. The role played by the main actors involved in the process in examined using the theory of moral development and the organizational politic perspective. The paper discusses the mechanisms available to raise ethical awareness and prevent academic misconduct, and the limitations of self-regulation and self-monitoring that prevails in the university system. It also examines the impact of ethics instruction and faculty ethical standards on students' behavior and concludes that ethics instruction can only be effective when the principles taught are in line with daily actions of their instructors. 相似文献
