    Description: Do transgenic crops cause agrobiodiversity erosion? We hypothesise that they increase productivity and reduce production risk and may therefore reduce farmers' demand for on-farm varietal diversity, especially when only a few transgenic varieties are available. We also hypothesise that varietal diversity can be preserved when more transgenic varieties are supplied. These hypotheses are tested and confirmed with panel data for the case of transgenic cotton in India. Cotton varietal diversity in India, with over 90 per cent adoption of transgenic technology, is now at the same level than it was before the introduction of this technology. Some policy implications are discussed.

    Description: This paper examines the role played by biodiversity goals in the design of agricultural policies. A bio-economic model is developed with a dynamic and multi-scale perspective. It combines biodiversity dynamics, farming land-uses selected at the micro level and public policies at the macro level based on financial incentives for land-uses. The public decision-maker identifies optimal subsidies or taxes with respect to both biodiversity and budgetary constraints. These optimal policies are then analysed through their private, public and social costs. The model is calibrated and applied to metropolitan France at the small agricultural region scale, using common birds as biodiversity metrics. First results relying on optimality curves and private costs stress the bio-economic trade-off between biodiversity and economic scores. In contrast, the analysis of public costs suggests that accounting for biodiversity can generate a second benefit in terms of public budget. Social costs defined as the sum of private and public costs also show possible bio-economic synergies.

    Description: This empirical study aims to shed light on the dynamic linkages between innovation, efficiency and productivity at the individual farm level. We use a comprehensive dataset for dairy farms in Germany for the period 1996–2010. Based on a directional distance frontier framework and the Luenberger index, we estimate the changes in efficiency, technical change and productivity over the period considered and simultaneously investigate possible factors for technically efficient milk production at farm level. We find that investments in innovative technology indeed increase the productivity of dairy production by shifting out the production frontier. Our findings further imply that investments in innovative dairy technologies require a sufficient level of complementary education to trigger also an increase in efficiency at farm level. The quality of human capital in terms of educational training seems finally crucial for a lasting increase in efficiency as a result of innovation.
