Studienarbeit aus dem Jahr 2002 im Fachbereich BWL - Unternehmensführung, Management, Organisation, Note: 1,7, Frankfurt School of Finance & Management, Veranstaltung: Innovationsmanagement, Sprache: Deutsch, Abstract: Das Ziel dieser Seminararbeit ist, nach einem einleitenden Abschnitt über allgemeine Definitionen, Eigenschaften und Erkenntnise der Diffusionsforschung einen Überblick über die historischen und aktuellen Diffusionsmodelle mathematischer Natur zu geben. Beginnend mit klassischen makroökonomisch orientierten Modellen wie dem berühmten Bass-Modell mit seinen zwei zentralen Kommunikationskanälen (interpersonal und Massenmedien) wird die Brücke zu mikroökonomisch objektorientierten Modellen geschlagen, die sowohl die Diffusion von Informationen als auch die komplexere Diffusion von innovativen Gütern untersuchen. Beide Modellklassen lassen sich gut miteinander vergleichen. Die mikroökonomisch fundierten Modelle zählen ebenso wie die Gleichgewichts- und Evolutionsmodelle, die in den kommenden Abschnitten vorgestellt werden, bereits zu den aktuellsten Forschungsergebnissen. Es werden sowohl jeweils die zentralen Resultate wie auch quantitative empirische Ergebnisse dieser Modelle präsentiert. Die hierzu benötigten mathematischen Werkzeuge von Differentialgleichungen über stochastische Prozesse bis hin zu unendlich dimensionalen Räumen wurden bei einigen Modellen demonstrationshalber ausführlich in den Text integriert, bei anderen auf das nötige Mindestmaß beschränkt, um den Rahmen der Arbeit nicht zu sprengen. Den Abschluss bildet die Untersuchung des Wettbewerbs in einem Industriedynamik-Modell mit zufälligen Eintritten heterogener, innovativer Newcomer-Firmen mit Verdrängungskriterien und erstaunlichen quantitativen Ergebnissen in Bezug auf die Verteilung der Lebensdauer und Größe innovativer Unternehmen.

Now in its fifth edition, Diffusion of Innovations is a classic work on the spread of new ideas. In this renowned book, Everett M. Rogers, professor and chair of the Department of Communication & Journalism at the University of New Mexico, explains how new ideas spread via communication channels over time. Such innovations are initially perceived as uncertain and even risky. To overcome this uncertainty, most people seek out others like themselves who have already adopted the new idea. Thus the diffusion process consists of a few individuals who first adopt an innovation, then spread the word among their circle of acquaintances—a process which typically takes months or years. But there are exceptions: use of the Internet in the 1990s, for example, may have spread more rapidly than any other innovation in the history of humankind. Furthermore, the Internet is changing the very nature of diffusion by decreasing the importance of physical distance between people. The fifth edition addresses the spread of the Internet, and how it has transformed the way human beings communicate and adopt new ideas.

Product sales, especially for new products, are influenced by many factors. These factors are both internal and external to the selling organization, and are both controllable and uncontrollable. Due to the enormous complexity of such factors, it is not surprising that product failure rates are relatively high. Indeed, new product failure rates have variously been reported as between 40 and 90 percent. Despite this multitude of factors, marketing researchers have not been deterred from developing and designing techniques to predict or explain the levels of new product sales over time. The proliferation of the internet, the necessity or developing a road map to plan the launch and exit times of various generations of a product, and the shortening of product life cycles are challenging firms to investigate market penetration, or innovation diffusion, models. These models not only provide information on new product sales over time but also provide insight on the speed with which a new product is being accepted by various buying groups, such as those identified as innovators, early adopters, early majority, late majority, and laggards. New Product Diffusion Models aims to distill, synthesize, and integrate the best thinking that is currently available on the theory and practice of new product diffusion models. This state-of-the-art assessment includes contributions by individuals who have been at the forefront of developing and applying these models in industry. The book's twelve chapters are written by a combined total of thirty-two experts who together represent twenty-five different universities and other organizations in Australia, Europe, Hong Kong, Israel, and the United States. The book will be useful for researchers and students in marketing and technological forecasting, as well as those in other allied disciplines who study relevant aspects of innovation diffusion. Practitioners in high-tech and consumer durable industries should also gain new insights from New Product Diffusion Models. The book is divided into five parts: I. Overview; II. Strategic, Global, and Digital Environments for Diffusion Analysis; III. Diffusion Models; IV. Estimation and V. Applications and Software. The final section includes a PC-based software program developed by Gary L. Lilien and Arvind Rangaswamy (1998) to implement the Bass diffusion model. A case on high-definition television is included to illustrate the various features of the software. A free, 15-day trial access period for the updated software can be downloaded from http://www.mktgeng.com/diffusionbook. Among the book's many highlights are chapters addressing the implications posed by the internet, globalization, and production policies upon diffusion of new products and technologies in the population.

Diffusion and growth phenomena abound in the real world surrounding us. Someexamples: growth of the world's population, growth rates of humans, public interest in news events, growth and decline of central city populations, pollution of rivers, adoption of agricultural innovations, and spreading of epidemics and migration of insects. These and numerous other phenomena are illustrations of typical growth and diffusion problems confronted in many branches of the physical, biological and social sciences as well as in various areas of agriculture, business, education, engineering medicine and public health. The book presents a large number of mathematical models to provide frameworks forthe analysis and display of many of these. The models developed and utilizedcommence with relatively simple exponential, logistic and normal distribution functions. Considerable attention is given to time dependent growth coefficients and carrying capacities. The topics of discrete and distributed time delays, spatial-temporal diffusion and diffusion with reaction are examined. Throughout the book there are a great many numerical examples. In addition and most importantly, there are more than 50 in-depth "illustrations" of the application of a particular framework ormodel based on real world problems. These examples provide the reader with an appreciation of the intrinsic nature of the phenomena involved. They address mainly readers from the physical, biological, and social sciences, as the only mathematical background assumed is elementary calculus. Methods are developed as required, and the reader can thus acquire useful tools for planning, analyzing, designing,and evaluating studies of growth transfer and diffusion phenomena. The book draws on the author's own hands-on experience in problems of environmental diffusion and dispersion, as well as in technology transfer and innovation diffusion.

Die Ziele, Institutionen und Instrumente der Umweltpolitik von Nationalstaaten sind sich in den letzen 30 Jahren ähnlicher geworden. Warum aber nähern sich Staaten in ihren regulativen Mustern an? Verbindliche internationale Standards existieren bei den meisten umweltpolitischen Innovationen bis heute nicht. Übernehmen Staaten also freiwillig Politiken, die anderswo entwickelt wurden? Unter welchen Bedingungen Prozesse der Diffusion politischer Innovationen wahrscheinlich sind, welche Mechanismen ihnen unterliegen und welche Akteure diese Dynamiken erzeugen, sind die zentralen Themen dieser Studie.
