Modern antitrust policy has a ‘love hate’ relationshipwith non-standard contracts that can overcome market failure.On the one hand, courts have abandoned various per se rulesthat once condemned such agreements outright, concluding thatmany non-standard contracts may produce benefits that are cognizableunder the antitrust laws.1 The prospect of such benefits, itis said, compels courts to analyze these agreements under theRule of Reason, under which the tribunal determines whethera given restraint enhances or destroys competition.2 At thesame time, courts, scholars, and the enforcement agencies haveembraced methods of rule of reason analysis that are undulyhostile to such agreements.3 In particular, courts and othersare too quick to view such agreements and the market outcomesthey produce as manifestations of market power. This articleseeks to explain why these agreements are still the object ofundue hostility.  相似文献

Telecommunications regulation has experienced a fundamentalshift from rate regulation to increased reliance on compelledaccess, perhaps best exemplified by the Telecommunications Actof 1996's imposition of no fewer than four new access requirements.Unfortunately, each access requirement is governed by a separateset of rules for determining both the scope and the price ofaccess. The resulting ad hoc regime has created difficult definitionalproblems and opportunities for regulatory arbitrage. In thisarticle we propose a system inspired by the discipline of mathematicsknown as graph theory that integrates all of the different formsof access into a single analytical framework. This system separatesdifferent access regimes into five categories: (1) retail access,(2) wholesale access, (3) interconnection access, (4) platformaccess, and (5) unbundled access. It also provides insightsinto how each type of access complicates the already difficultproblems of network configuration and management and introducesinefficient biases into decisions about network capacity anddesign. The approach we propose also provides insights intothe transaction cost implications of the different types ofaccess. Drawing on the Coasean theory of the firm, our approachexamines the tradeoffs between internal governance costs andthe external transaction costs of providing access to offera theory of network boundaries. This framework shows how accessregulation distorts networks' natural boundaries and providesa basis for evaluating whether private ordering through marketswould lead to more efficient network design.  相似文献

Eighteen external quality assessment (proficiency testing) samples were prepared from client specimens collected with the Intercept® oral fluid collection device and by spiking drug-free oral fluid. Samples were circulated in pairs at quarterly intervals to 13 UK and USA based laboratories for analysis by a panel of OraSure micro-plate Intercept® enzyme immunoassay kits and hyphenated mass spectrophotometric techniques. During the survey, there was a single case of non-specificity in a false report for methadone. The major errors were of lack of sensitivity relative to the concentration thresholds specified for the immunoassays. The sensitivity for overall ‘present’/‘not found’ reports calculated as true positives/(true positives + false negatives) were for the amfetamine specific assay 50%, methyl-amfetamines 93%, barbiturates 64%, cannabinoids 73%, cocaine and metabolites 100%, benzodiazepines 69%, methadone 95%, opiates 79% (opiates excluding oxycodone 93%), phencyclidine 93% and human gamma-globulin 97%. A small number of the sensitivity errors were attributable to errors in chromatographic confirmation techniques.  相似文献

This report assesses the effects on peripheral oxygen saturation and heart rate that positional restraint induces when a person is prone, handcuffed, and "hog-tied." Peripheral oxygen saturation and heart rate were monitored at rest, during exercise, and during recovery from exercise for 10 adult subjects. The effects of positional restraint produced a mean recovery time that was significantly prolonged. Consequently, the physiological effects produced by positional restraint should be recognized in deaths where such measures are used.  相似文献

This paper compares the Medicare prospective payment system (PPS) to four all-payer rate-setting systems that operated under HCFA waiver authority. The study examines the experience of Medicare, Medicaid, and commercial insurers under the two approaches. Data from several American Hospital Association surveys and from Medicaid 2082 report forms are analyzed. The paper concludes that the all-payer waiver programs have been as successful as PPS in controlling the rate of growth in Medicare costs. In addition, Medicaid programs are more successful in controlling their outlays in all-payer rate-setting environments than when they "go alone." Finally, there is no evidence to suggest that hospitals can increase charges in response to greater financial need under either PPS or the state waivers. Nevertheless, it appears that commercial insurers are better able to compete with Blue Cross plans in all-payer rate-setting states than elsewhere.  相似文献
