Selected Economic Analysis at the Antitrust Division: The Year in Review

Of the many activitiesof the Antitrust Division of theU.S. Department of Justice, we havesummarized some that raise interestingeconomic issues. We describe recentimprovements in the methodology to beused in ``coordinated effects' analysisof mergers. We also discuss four casesbrought by the DOJ that raise issues ofmarket definition, the influence ofcommon partial ownership of competitors,and the effects of fringe suppliers inconstraining collusion by large firms.     

Controlling for the Impact of Variable Liquidity in Commercial Real Estate Price Indices

Liquidity in private asset markets is notoriously variable over time. Therefore, indices of changes in market value that are based on asset transaction prices will systematically reflect intertemporal differences in the ease of selling a property. We define and develop a concept of "constant-liquidity value" in the context of a model that is characterized by pro-cyclical volume of trading. We then present an econometric model that allows for estimation of both a standard transaction-based price index and a constant-liquidity index. Our application to the NCREIF database reveals that, in the case of institutional commercial real estate investment, constant-liquidity values tend to lead transaction-based and appraisal-based indices in time, and also to display greater volatility and cycle amplitude. The differences can be significant for strategic investment policy viewed from a mean-variance portfolio optimization perspective.     

Reframing science and other local knowledge traditions

By recognizing science as a set of local practices it becomes possible to ‘decentre’ it and develop a framework within which all knowledge systems can be equitably compared. It is argued that all knowledge traditions are spatial in that they link people, sites and skills. In order to ensure the continued existence of the diversity of knowledge traditions rather than have them absorbed into the great imperialist archive we need to enable disparate knowledge traditions to work together through the creation of a third space in which the social organization of trust can be negotiated.     

Obtaining global market access for GMPCS

Demand for wireless telephony is huge and the potential for GMPCS, in particular, is widely recognized. However, the most serious problems to the introduction of GMPCS are not technical, nor financial, but are rather the political and regulatory barriers—notably fear of bypass and security concerns. Inmarsat does not believe that there should be any a priori limit to the number of GMPCS operators offering satellite capacity to national service providers. The market can best determine which will be successful. However, before countries open their markets, they will need to be convinced that it is in their interest to do so.     

The liability to consumers of manufacturers of defective goods — An Australian perspective

There is an increasing tendency for consumers to regard the manufacturer as being primarily responsible for the safety and quality of consumer goods, even though in many if not most legal systems the common assumption by the consumer that the manufacturer rather than the retailer bears the primary liability for defective goods is not in fact correct. The legal position of the consumer in Australia under the general law of contract and tort is outlined as a background to the reforms made in 1978 by an important amendment to the Federal Trade Practices Act. A manufacturer (or importer) of consumer goods now is bound by statutory obligations, enforceable by the consumer, in respect of the quality of his goods. He is also bound by any express warranty given by him, and is liable where the goods require to be repaired or where replacement parts are required, but repair facilities or spare parts are not reasonably available. Except in the case of the obligations relating to the provision of spare parts and repair facilities, the manufacturer's statutory obligations cannot be excluded or limited. The Act also contains provisions limiting the time during which a consumer can commence an action against a manufacturer.Although the author considers that there are some defects in the legislation, he concludes that it represents a significant advance in the legal protection of the consumer's economic interests. There is a need for the expansion of existing mechanisms for the informal resolution of consumer claims, but the author also believes that the existence of the new legislative code setting out reasonably clearly defined rights will often in practice greatly strengthen the position of government agencies and others in attempting to negotiate a settlement on behalf of a consumer. Damages recoverable by a consumer from a manufacturer extend to consequential losses, including death or personal injury. As a result, a measure of strict liability for personal injury caused by defective products has been imposed on manufacturers. The legislation does not, however, offer a comprehensive regime of strict liability for personal injury and many anomalous situations will arise. The author considers that there is therefore a need in Australia for a review of the whole question of strict liability for personal injury caused by defective products, although even were this to occur there would still exist a strong need for a scheme such as that discussed in the article to govern the claim of a consumer for economic losses caused by the supply of defective or inferior products.

Die Haftung des Warenherstellers bei Mängeln der Sache — eine australische Position zum Verbraucherschutz

Zusammenfassung Konsumenten gehen in immer stärkerem Maße davon aus, daß primär der Hersteller für die Güte und Sicherheit von Bedarfsgegenständen verantwortlich ist. Dem steht bislang die Rechtstradition der meisten Länder entgegen, wonach der Verkäufer und nicht der Hersteller primär für Fehler und Mängel verantwortlich ist.Der Aufsatz stellt die rechtliche Stellung des Konsumenten in Australien vor dem Hintergrund allgemeiner vertrags- und deliktsrechtlicher Regelungen dar. 1978 ist durch eine Novelle des Federal Trade Practices Act eine wichtige Reform eingeführt worden. Der Hersteller oder Importeur von Verbrauchsgütern (consumer goods) ist jetzt kraft Gesetzes, das vom Verbraucher im Klagewege durchgesetzt werden kann, einstandspflichtig für die Qualität seiner Waren. Er ist gleichermaßen unter einer Garantieerklärung haftbar. Er hat auch dafür einzustehen, daß Güter, die Wartung, Reparatur oder Ersatzteile benötigen, ordnungsgemäß und zu vernünftigen Bedingungen gewartet werden können. Die Pflichten des Herstellers können durch vertragliche Abrede nicht ausgeschlossen oder eingeschränkt werden, mit der Ausnahme der Wartungsverpflichtung. Die Novelle enthält schließlich Bestimmungen über Ausschluß- und Verjährungsfristen für die Ansprüche des Verbrauchers, wobei sie sich an den EG-Richtlinienentwurf zur Produkthaftung anlehnt.Auch wenn der Autor einige Vorschriften der Novelle kritisch würdigt, so geht er davon aus, daß sie einen wichtigen Fortschritt im rechtlichen Schutz der wirtschaftlichen Interessen des Verbrauchers darstellt. Daneben besteht weiterhin ein Bedarf zur Verbesserung der Rechtsdurchsetzung, aber die Existenz der Novelle und der dort enthaltenen klar definierten Pflichten des Herstellers erleichtert staatlichen Behörden und anderen den Schutz der Rechte des Konsumenten. Die vom Hersteller zu liquidierenden Schäden betreffen auch Folgeschäden einschließlich Tod und Personenschäden. Im Ergebnis haftet der Hersteller ohne Verschulden für Produktfehler. Allerdings ist die Gesetzeslage nicht vollständig befriedigend; es fehlt ein umfassendes System der Gefährdungshaftung für Produktfehler, etwa gegenüber Dritten, die das fehlerhafte Produkt lediglich benutzen, ohne es selbst gekauft zu haben. Nach Auffassung des Autors muß deshalb in Australien die Produkthaftung für Personenschäden neu überdacht werden. Daneben bleibt die — durch die Novelle befriedigte — Notwendigkeit, den Verbraucher gegenüber Vermögensschäden bei Lieferung eines mangelhaften Produktes dadurch zu schützen, daß man ihm einen Direktanspruch gegen den Hersteller zuerkennt.
