| In recent years, output on genetic diversity in the economic literature has included conceptual pieces on the definition and measurement of crop genetic diversity, methodologies for estimating its value, and efforts to analyze its contribution to productivity and stability. However, because biological diversity refers in general to a broad area of scientific inquiry, the growing quantity of literature has also generated some confusion over the definition, measurement, and interpretation of genetic diversity in the context of economic analysis. This paper addresses some of the measurement issues encountered in incorporating genetic diversity into economic analysis by presenting a synthesis of several of the relevant concepts and tools. Using data collected... |

| Initial efforts to estimate the effects on productivity of diversity among modern varieties in a production function framework have been unsatisfactory in at least two respects. First, the conventional primal approach estimates the marginal effects of diversity on technical efficiency but is unable to examine issues of allocative efficiency since it does not explicitly address producer behavior with respect to prices. Second, measures of genetic diversity used in previous studies may not have fully represented the diversity present in the crop. The development and incorporation of a biologically meaningful index of crop genetic diversity into an economic decision-making model is not straightforward. Previous studies have most often used diversity... |
