    The Beginnings and Prospective Ending of “End-to-End”: An Evolutionary Perspective On the Internet’s Architecture

    Get PDF
    The technology of “the Internet” is not static. Although its “end-to- end” architecture has made this “connection-less” communications system readily “extensible,” and highly encouraging to innovation both in hardware and software applications, there are strong pressures for engineering changes. Some of these are wanted to support novel transport services (e.g. voice telephony, real-time video); others would address drawbacks that appeared with opening of the Internet to public and commercial traffic - e.g., the difficulties of blocking delivery of offensive content, suppressing malicious actions (e.g. “denial of service” attacks), pricing bandwidth usage to reduce congestion. The expected gains from making “improvements” in the core of the network should be weighed against the loss of the social and economic benefits that derive from the “end-to-end” architectural design. Even where technological “fixes” can be placed at the networks’ edges, the option remains to search for alternative, institutional mechanisms of governing conduct in cyberspace.

    The Effect of Identity Preserved Premiums on Elevator Grain Flows

    Get PDF
    The effect of identity preserved premiums on a grain elevator's received volumes is modeled using stochastic simulation across the harvest season. A feedback loop simulates competing elevators' bid prices and tracks producer delivery decisions using arbitrage criteria at competing market elevators. Results provide information about the sensitivity of distance thresholds in producer delivery decisions given IP premiums.Crop Production/Industries,

    Smart Grid Communications: Overview of Research Challenges, Solutions, and Standardization Activities

    Full text link
    Optimization of energy consumption in future intelligent energy networks (or Smart Grids) will be based on grid-integrated near-real-time communications between various grid elements in generation, transmission, distribution and loads. This paper discusses some of the challenges and opportunities of communications research in the areas of smart grid and smart metering. In particular, we focus on some of the key communications challenges for realizing interoperable and future-proof smart grid/metering networks, smart grid security and privacy, and how some of the existing networking technologies can be applied to energy management. Finally, we also discuss the coordinated standardization efforts in Europe to harmonize communications standards and protocols.Comment: To be published in IEEE Communications Surveys and Tutorial

    Consumer preferences and last mile pricing in the postal sector

    Get PDF
    The paper analyzes consumer preferences towards a potential two-part tariff in the postal sector. Based on the empirical results we analyze the welfare effects of a two-part tariff when applied in the Swiss letter market.Pricing, Two-part tariff, Universal Service, Receiver Pays Principle, Consumer Preferences

    Intellectual Property, Antitrust and Strategic Behavior

    Get PDF
    Economic growth depends in large part on technological change. Laws governing intellectual property rights protect inventors from competition in order to create incentives for them to innovate. Antitrust laws constrain how a monopolist can act in order to maintain its monopoly in an attempt to foster competition. There is a fundamental tension between these two different types of laws. Attempts to adapt static antitrust analysis to a setting of dynamic R&D competition through the use of 'innovation markets' are likely to lead to error. Applying standard antitrust doctrines such as tying and exclusivity to R&D settings is likely to be complicated. Only detailed study of the industry of concern has the possibility of uncovering reliable relationships between innovation and industry behavior. One important form of competition, especially in certain network industries, is between open and closed systems. We have presented an example to illustrate how there is a tendency for systems to close even though an open system is socially more desirable. Rather than trying to use the antitrust laws to attack the maintenance of closed systems, an alternative approach would be to use intellectual property laws and regulations to promote open systems and the standard setting organizations that they require. Recognition that optimal policy toward R&D requires coordination between the antitrust and intellectual property laws is needed.

    Which economic model for a water-efficient Europe? Report of a CEPS Task Force. CEPS Task Force Report, 27 November 2012

    Get PDF
    This CEPS Task Force Report focuses on how to improve water efficiency in Europe, notably in public supply, households, agriculture, energy and manufacturing as well as across sectors. It presents a number of recommendations on how to make better use of economic policy instruments to sustainably manage the EU’s water resources. Published in the run-up to the European Commission’s “Blueprint to Safeguard Europe’s Waters”, the report contributes to the policy deliberations in two ways. First, by assessing the viability of economic policy instruments, it addresses a major shortcoming that has so far prevented the 2000 EU Water Framework Directive (WFD) from becoming fully effective in practice: the lack of appropriate, coherent and effective instruments in (some) member states. Second, as the Task Force report is the result of an interactive process involving a variety of stakeholders, it is able to point to the key differences in interpreting and applying WFD principles that have led to a lack of policy coherence across the EU and to offer some pragmatic advice on moving forward
