| The attractiveness of targeted environmental policies on farmlands depends crucially on the opportunity costs of the conservation programs. We use a crop diversity index as an indicator of environmental output to compare the efficiency of conventional and organic crop farms. Technical efficiency scores are estimated by applying data envelopment analysis to a sample of Finnish farms for the period 1994 – 2002. We also estimate shadow values, or the opportunity costs, of producing crop diversity. Our results show that there is variation in the shadow values between farms and the technology adopted. The findings provide a basis for designing cost-effective policy instruments such as auctions for conservation payments. |

| For policy making, it is important to identify the types of farms that are most efficient in enhancement of environmental quality, e.g., conservation of biodiversity. Attractiveness of conservation of biodiversity depends crucially on the opportunity costs of conservation. We use a crop diversity index as an indicator of environmental output to compare effciency of conventional and organic crop farms. Non-parametric technical efficiency scores are estimated applying data envelopment analysis on a sample of Finnish crop farms for 1994-2001. We also estimate opportunity costs, or shadow values, of producing crop diversity. According to our results, there is variation in shadow values of crop diversity between the farms and technology adopted. This... |
