What's happening in the world of product innovation? What are the tough issues that managers are facing? And what's going to happen in the remaining years of this decade? In this article, several members of the Editorial Board of The Journal of Product Innovation Management offer their ideas about where the important problems lie. This is the fodder for a good round table discussion and through the medium of this journal we'll engage in such a discussion in this and a subsequent issue. 相似文献

Zusammenfassung Die internationale Verteilung der Handelshilfe: eine quantitative Analyse des Systems von Exportquoten für Kaffee. - Die bisherigen
Untersuchungen über die internationale Verteilung der Entwicklungshilfe haben sich haupts?chlich mit der Finanzhilfe befa▾t.
Dagegen fehlen Untersuchungen über die Handelshilfe, obgleich es eine ganze Reihe von handelspolitischen Ma▾nahmen gibt, die
implizite Transfers an Entwicklungsl?nder einschlie▾en. In diesem Aufsatz werden die Bestimmungsgründe für Handelshilfe theoretisch
gekl?rt, und empirisches Material über implizite Schenkungen und Einnahmen wird vorgelegt, die in einer der Formen der Handelshilfe
enthalten sind, n?mlich in dem System von Exportquoten auf dem Weltkaffeemarkt. Dabei wird das unterschiedliche Verteilungsmuster
der Handelshilfe nach dem Internationalen Kaffeeabkommen einerseits und der offiziellen Entwicklungshilfe andererseits herausgearbeitet.
Es wird gezeigt, da▾ die Verteilung der Handelshilfe davon abh?ngt, ob ein Land Kaffeeexporteur oder -importeur ist, ob es
Mitglied des Abkommens ist oder nicht und wie seine Netto-Handelsposition ist. Bedürftigkeit spielt keine Rolle bei der Verteilung
dieser Art von Handelshilfe.
Résumé L’allocation internationale de l’aide assujettie au commerce: une analyse quantitative pour le systéme de quota exportatrice de café. - Les études existantes sur l’allocation internationale de l’aide ont concentré principalement sur l’aide financière. Il n’y a pas d’études sur l’allocation de l’aide assujettie au commerce (AAC) bien qu’une grande variété des mesures de politique commerciale existe qui inclut des transferts implicites en faveur des pays en voie de développement. Cette étude clarifie théoriquement les déterminants de l’AAC et présente quelque évidence empirique pour des donations et recettes implicites dans un des types de l’AAC, c’est le système de quota exportatrice dans le marché mondial de café. La structure d’allocation de l’AAC sous l’Accord International de Café et de l’assistance officielle étrangère est analysée. L’auteur démontre que la distribution des flux de l’aide des pays dépend de la question si les pays sont des exportateurs ou des importateurs de café, des membres ou non-membres de l’Accord aussi bien de leur position commerciale nette. Indigence n’est pas importante pour l’allocation de cette forme de l’AAC.
Resumen La asignación internacional de ayuda al desarrollo ligada al comercio: un análisis cuantitativo del sistema de cuotas de exportación de café. - Los estudios existentes sobre la asignación internacional de la ayuda al desarrollo se concentran especialmente en la ayuda financiera. Faltan estudios sobre la ayuda al desarrollo ligada al comercio, a pesar de la gran variedad de medidas de política comercial que incluyen una transferencia implícita a los países en desarrollo. En este estudio se clarifican teóricamente las déterminantes de la ayuda al desarrollo ligada al comercio y se presenta evidencia empírica sobre donaciones implícitas en relación a una de las formas de ayuda ligada al comercio, el sistema de cuotas de exportación en el mercado mundial del café. Se elabora el patrón diferencial de asignación de ayuda ligada al comercio bajo el Acuerdo International del Café y la ayuda oficial. Se muestra que la distribución internacional de los flujos de ayuda depende de las siguiente características: si los países son exportadores o importadores de café, signatarios del acuerdo o no y de su posición comercial neta. La asignación de esta forma de ayuda ligada al comercio es independiente del grado de necesidad de ayuda.相似文献

The introduction of competition into utilities is currentlybeing pursued in the many countries, including the UK. Competitioncan take various forms, such as competition for outputs, inputs,franchises, and outright takeovers. Attention is currently focusedon output competition, whereby customers are being given a choiceof final supplier in many industries. We consider the implicationsof the introduction of such competition, including the effectson industrial structure and contracts, cross-subsidies and distributionalconcerns, and uncertainty and stranded contracts. We also analysethe transitional problems encountered as competition is introducedand suggest that the UK regulators and government have, in somekey respects, failed to define a clear and consistent policy. 相似文献

This paper addresses the question of whether shares of public real estate companies should be treated as real estate or as
equity investments. Because theoretical considerations do not suffice for making such a classification, we empirically investigate
correlation structures and cointegration relationships of private and public real estate and equity markets for the United
States and the United Kingdom. Our results suggest that public real estate stocks show similarities to the general stock market
with regard to short-term return co-movements. For long-term investment horizons, the interdependence between direct and securitized
real estate is much stronger. However, in the latter case, real estate stocks substantially lead the private property markets.

The performance of active portfolio managers who must comply with a weights constraint is often assessed against a benchmark. The weights constraint is common as the funds are committed by their own prospectus to a minimum (or maximum) portfolio concentration. We characterize the optimal asset allocation and analyze the implications of the weights constraint on the manager's performance and on the relevance of the information ratio. We obtain that because of the weights constraint, at the optimum, the information ratio often decreases when the manager is free to deviate more from the benchmark. 相似文献

This paper develops a method to capture anisotropic spatial autocorrelation in the context of the simultaneous autoregressive model. Standard isotropic models assume that spatial correlation is a homogeneous function of distance. This assumption, however, is oversimplified if spatial dependence changes with direction. We thus propose a local anisotropic approach based on non-linear scale-space image processing. We illustrate the methodology by using data on single-family house transactions in Lucas County, Ohio. The empirical results suggest that the anisotropic modeling technique can reduce both in-sample and out-of-sample forecast errors. Moreover, it can easily be applied to other spatial econometric functional and kernel forms. 相似文献

Cellular phones are considered one of the success stories of contemporary technology diffusion: there are three billion cellular telephones globally, and just over six billion people. This article describes the distributional boundary of the cellular telephone enterprise, as we see it in data from Mozambique. A telephone survey of mobile phone users there revealed that men outnumbered women, especially at higher levels of service and that most were urban, with a particular concentration in the capital city. Thus while pre-paid telephone plans have made basic cellular service affordable to many Mozambicans, the lack of rural infrastructure stills puts access out of the reach of a majority. In addition, pre-paid users pay more per minute for their service—probably not a fair situation for the poor families that tend to take this route to telecommunications. 相似文献

Abstract Individual viewing decisions have a direct impact on the media planning of television advertisers and, consequently, on the revenues of the major television networks. This paper represents an attempt to better understand these decisions. We use Nielsen people meter data to build a perceptual space for programs. That space is then used to develop models explaining viewers' decision to watch television and their choice of programming. The program-choice model is a clusterwise logit model which searches for segments with similar viewing preferences. A segment-level logit model is then used to model the on-off decision. These models can be used by advertisers and advertising agencies to understand the viewing audience better, and thus to help guide their advertising media placement decisions. The models can also help television networks design programs and program schedules that are more attractive to viewers (and thus advertisers). 相似文献
