Wireless Network Virtualization: Opportunities for Sharing in the 3.5 GHz Band

In this paper, we evaluate the opportunities that Wireless Network Virtualization (WNV) can bring for spectrum sharing by focusing on the regulatory framework that has been deployed by the Federal Communications Commission (FCC) for the 3.5GHz band. Pairing this regulatory approach with WNV permits us to present a sharing proposal where emphasis is made on increasing resource availability and providing flexible methods for negotiating for resource access. We include an economics framework that aims at presenting an additional perspective on the attainable outcomes of our sharing proposal. We find that by pairing regulatory flexibility with an enabling technology, within an appropriate economics context, we can increase resource access opportunities and enhance current sharing arrangements

The impact of bundling licensed and unlicensed wireless service

Unlicensed spectrum has been viewed as a way to increase competition in wireless access and promote innovation in new technologies and business models. However, several recent papers have shown that the openness of such spectrum can also lead to it becoming over congested when used by competing wireless service providers (SPs). This in turn can result in the SPs making no profit and may deter them from entering the market. However, this prior work assumes that unlicensed access is a separate service from any service offered using licensed spectrum. Here, we instead consider the more common case were service providers bundle both licensed and unlicensed spectrum as a single service and offer this with a single price. We analyze a model for such a market and show that in this case SPs are able to gain higher profit than the case without bundling. It is also possible to get higher social welfare with bundling. Moreover, we explore the case where SPs are allowed to manage the customers' average percentage of time they receive service on unlicensed spectrum and characterize the social welfare gap between the profit maximizing and social welfare maximizing setting.Comment: 15 pages, 10 figures, accepted and to appear at IEEE International Conference on Computer Communications (INFOCOM), 201

Lessons for Health Reform From the Federal Employees Health Benefits Program

Explores the feasibility of opening up the program to non-federal employees as a way to expand coverage. Outlines lessons learned on countering selection issues, maintaining a wide array of benefit packages, and offsetting costs and premium fluctuations

Reforming finance in transitional socialist economies : avoiding the path from shell money to shell games

In the late 1980s, transitional socialist economies (TSEs) in Central and Eastern Europe were only somewhat more sophisticated than shell money systems: savings books or currency had to be used for most transactions and there was no risk assessment, information monitoring and acquisition, or portfolio management. The TSEs have moved toward a two-tiered banking system but they lag in the development of competitive, market-based financial systems. In several TSEs the financial system seems to be part of a shell game to hide the losses of the real economy. The authors argue that rapid, successful economic reform requires putting the shell game to an end. They review several contentious issues of financial reform in the TSEs, especially issues involving macrofinance, corporate finance, the internal debt problems, and the need to build efficient banks. The authors contend that the banks should be"cleaned up"when they are privatized, to prevent the quick reemergence of debt problems. They believe that either of the proposed alternatives for shaping financial systems in the TSEs - very highly capitalized banking or narrow banking - would minimize the need for future support. Either alternative would reduce leverage in the TSEs and provide more financial stability. But taking concerns about moral hazard to an extreme - prohibiting debt finance - could starve new firms for credit and limit economic growth.Economic Theory&Research,Financial Crisis Management&Restructuring,Environmental Economics&Policies,Banks&Banking Reform,Financial Intermediation

Healthcare reform in Russia: problems and prospects

This paper examines the prospects for reform of Russia’s healthcare system. It begins by exploring a number of fundamental imbalances that characterise the current half-reformed system of healthcare provision before going on to assess the government’s plans for going ahead with healthcare reform over the medium term. The challenges it faces include strengthening primary care provision and reducing the current over-reliance on tertiary care; restructuring the incentives facing healthcare providers; and completing the reform of the system of mandatory medical insurance

The Impact of Opt-In Privacy Rules on Retail Credit Markets: A Case Study of MBNA

U. S. privacy laws are increasingly moving from a presumption that consumers must object to ( opt out of) uses of personal data they wish to prohibit to a requirement that they must explicitly consent ( opt in ) to uses they wish to permit. Despite the growing reliance on opt-in rules, there has been little empirical research on their costs. This Article examines the impact of opt-in on MBNA Corporation, a diversified, multinational financial institution. The authors demonstrate that opt-in would raise account acquisition costs and lower profits, reduce the supply of credit and raise credit card prices, generate more offers to uninterested or unqualified consumers, raise the number of missed opportunities for qualified consumers, and impair efforts to prevent fraud. These costs would be incurred despite the fact that as of the end of 2000, only about two percent of MBNA\u27s customers had taken advantage of existing voluntary opportunities to opt out of receiving MBNA\u27s direct mail marketing offers. If Congress were to adopt opt-in laws applicable to financial information, the impact across the economy on consumers and businesses would be significant
