Findings from a systematic qualitative study of the magazines of two Belgian consumer organizations revealed that additives were seen as providing no benefits to consumers, for they could be used to reduce the quality of both the ingredients and the production process. They were perceived as a means of deceiving the public, with portrayal of consumers as powerless in the struggle for control over the types and amounts of additives they ingested. In turn, the limitations were seen as a failure of government and scientific institutions to provide the necessary protection.
AGRICOLA IND 90019481, Technical change is dynamic, recursive, and endogenous to the economic system. However, empirical studies usually treat technology as exogenous, defining technical change in terms of its end result: changes in some production possibilities set. An endogenous view of technical change is necessary to understand, anticipate, and perhaps alter the development and use of new technologies and their associated problems. This article outlines a conceptual framework in which technical change is endogenous. The framework accounts for the dynamic and recursive interactions between research and development activities, the adoption and diffusion of new innovations, and the regulatory and institutional environment. As an example, the development of glyphosate-tolerant crops is discussed to show how the framework can be used to identify, organize, and understand the important variables and relationships for a specific case of technical change.
