EU member states require farmers growing transgenic maize to respect a minimum distance from fields with non-transgenic maize. Previous studies have theoretically argued that such minimum distance requirements may lead to a so-called ‘domino effect’ where farmers who want to grow transgenic...

In 1998, Genetically Modified (GM) maize entered European Agriculture. After the publication of the European Commission's guidelines on coexistence in 2003, Portugal developed ex-ante regulatory and ex-post tort liability rules on the coexistence of GM and non-GM maize crops. There is an...

Sustainability is a complex multidimensional concept that entails economic, environmental, and social aspects. The sustainable value (SV) method developed by F. Figge and T. Hahn [Ecol. Econ. 48(2004) 173-187] is one of the most promising attempts to measure sustainability performance of firms....

Assessing the benefits of climate policies is complicated due to ancillary benefits: abatement of greenhouse gases also reduces local air pollution. The timing of the abatement measures influences both the economic costs and ancillary benefits. This paper conducts efficiency analysis of ten...

Nutrients such as nitrogen and phosphorus have a dual role as inputs to crop production and as pollutants to water, air, and soil. The nutrient surplus measures are frequently used as indicators of environmental performance or eco-efficiency at micro level of individual farms and at macro levels...
