Die vorliegende Arbeit befasst sich mit Innovationsdiffusionsmodellen und deren Anwendung in der Marketingpraxis. Sie hat zwei Ziele: Einen Überblick über existierende Innovationsmodelle zu schaffen und ein neues besseres Modell zu entwickeln. Es wird ein neuer Klassifizierungsansatz...

There is an evolution in the process used by standards-developmentorganizations (SDOs) and this is changing the prevailing standardsdevelopment activity (SDA) for information and communications technology(ICT). The process is progressing from traditional SDA modes, typicallyinvolving the...

There is little empirical evidence concerning the effects of intellectual property rights (IPR) on a technologically advanced developing country. Complete enumeration of the Mexican maize breeding industry showed that, contrary to the hypothesis that IPR would provide, in a technologically...

We develop a new partial equilibrium, four-region world trade model for the soybean complex comprising soybeans, soybean oil, and soybean meal. In the model, some consumers view genetically modified Roundup Ready (RR) soybeans and products as weakly inferior to conventional ones; the RR seed is...

This paper studies how the strength of intellectual property rights (IPRs) affects investments in biological innovations when the value of an innovation is stochastically reduced to zero because of the evolution of pest resistance. We frame the problem as a research and development (R&D)...

Notwithstanding the ambiguous research and productivity promoting effects of plant varietyprotections (PVPs), even in developed countries, many developing countries have adoptedPVPs in the past few years to comply with their Trade-Related Aspects of IntellectualProperty Rights (TRIPS)...

Public-private partnerships offer potentially important opportunities for pro-pooragricultural research in developing countries. Yet in the international agricultural researchcommunity--and with regard to the Consultative Group on International Agricultural Research(CGIAR) itself--we see few...

This paper develops a model of heterogeneous producers to examine theeconomic causes of IPR infringement and its consequences for the welfare of the interestgroups and the pricing and adoption of a new technology (i.e., a genetically modifiedseed) in the context of a small open developing...
