Designing Competition Policy for Telecommunications
This paper explores the role of the essential facilities doctrine in circumscribing the scope of network sharing obligations in telecommunications. Among other things it argues that a proper application of the doctrine of essential facilities should recognize the prominence of dynamic over static efficiency in promoting consumer welfare. Regulators may be averse to recognizing these tradeoffs because unlike the behavior of prices the welfare losses from foregone innovation may be unobservable to the regulatorsâ constituency. Moreover, an emphasis on dynamic efficiency requires the short-term regulator to take the âlong viewâ â fostering the competitive process rather than emulating the competitive outcome.
Non-exclusionary input prices
This paper models a vertically-integrated provider that is a monopoly supplier of an input that is essential for downstream production. An input price that is âtoo highâ can lead to inefficient foreclosure and one that is âtoo lowâ creates incentives for non-price discrimination. The range of non-exclusionary input prices is circumscribed by the input prices generated on the basis of upper-bound and lower-bound displacement ratios. The admissible range of the ratio of downstream to upstream price-cost margins is increasing in the degree of product differentiation and reduces to a single ratio in the limit as the products become perfectly homogeneous
The ACTTION-APS-AAPM Pain Taxonomy (AAAPT) Multidimensional Approach to Classifying Acute Pain Conditions.
Objective: With the increasing societal awareness of the prevalence and impact of acute pain, there is a need to develop an acute pain classification system that both reflects contemporary mechanistic insights and helps guide future research and treatment. Existing classifications of acute pain conditions are limiting, with a predominant focus on the sensory experience (e.g., pain intensity) and pharmacologic consumption. Consequently, there is a need to more broadly characterize and classify the multidimensional experience of acute pain.
Setting: Consensus report following expert panel involving the Analgesic, Anesthetic, and Addiction Clinical Trial Translations, Innovations, Opportunities, and Networks (ACTTION), American Pain Society (APS), and American Academy of Pain Medicine (AAPM).
Methods: As a complement to a taxonomy recently developed for chronic pain, the ACTTION public-private partnership with the US Food and Drug Administration, the APS, and the AAPM convened a consensus meeting of experts to develop an acute pain taxonomy using prevailing evidence. Key issues pertaining to the distinct nature of acute pain are presented followed by the agreed-upon taxonomy. The ACTTION-APS-AAPM Acute Pain Taxonomy will include the following dimensions: 1) core criteria, 2) common features, 3) modulating factors, 4) impact/functional consequences, and 5) putative pathophysiologic pain mechanisms. Future efforts will consist of working groups utilizing this taxonomy to develop diagnostic criteria for a comprehensive set of acute pain conditions.
Perspective: The ACTTION-APS-AAPM Acute Pain Taxonomy (AAAPT) is a multidimensional acute pain classification system designed to classify acute pain along the following dimensions: 1) core criteria, 2) common features, 3) modulating factors, 4) impact/functional consequences, and 5) putative pathophysiologic pain mechanisms.
Conclusions: Significant numbers of patients still suffer from significant acute pain, despite the advent of modern multimodal analgesic strategies. Mismanaged acute pain has a broad societal impact as significant numbers of patients may progress to suffer from chronic pain. An acute pain taxonomy provides a much-needed standardization of clinical diagnostic criteria, which benefits clinical care, research, education, and public policy. For the purposes of the present taxonomy, acute pain is considered to last up to seven days, with prolongation to 30 days being common. The current understanding of acute pain mechanisms poorly differentiates between acute and chronic pain and is often insufficient to distinguish among many types of acute pain conditions. Given the usefulness of the AAPT multidimensional framework, the AAAPT undertook a similar approach to organizing various acute pain conditions

Asymmetrical regulation : Principles for emerging competition in local service markets
Asymmetrical regulation in the long-distance market forced AT&T to adopt a strategy of 'optimal mediocrity' with correspondingly high social cost -- both measurable and unmeasurable. This experience suggests that the evolution of competition in local service markets be based on the principle that welfare-enhancing competition requires a fair and symmetric regulatory process. Anything else should be considered suspect.
The emerging market for 'faultless' telecommunications
The failure of a telecommunications central office in Hinsdale, Illinois, in May 1988 caused widespread service outages and brought the local economy to a virtual halt. In the process it highlighted the emerging market for back-up networks. At present local exchange carriers are obliged to offer a free stand-by service to customers who choose an alternative network for regular use. This conceals the true market value of this 'insurance' service, and should be ended. The author argues that local exchange carriers should vigorously enter the market for 'faultless' networks by offering a range of back-up options for their own primary service, just as the automotive and consumer products industries do.
