| Economic research on structural change in agriculture has repeatedly induced controversies about basic theoretical concepts, such as rational behaviour and equilibrium, and their analytical and political implications. To contribute to the epistemological dimension of this debate, the article gives an overview of three paradigms to economic modelling whose proponents have been inspired by physics, biology, and chemistry. The key concepts of general equilibrium theory, evolutionary economics and the “social chemistry” of Jon Elster are presented and compared. While all keep the idea that intentional individual action can explain aggregate outcomes that are nevertheless unintended, they differ in assumptions concerning preferences and the characteristics of... |

| This paper identifies major future trends and driving factors and perspectives and challenges resulting from them for European agriculture and food sectors until the year 2020. The focus of the paper is an analysis of key driving forces and the provision of a well developed reference scenario under the assumption of continued CAP reform and taking into account the framework discussions in the Doha Development Round. To assess the impact of policies the paper also examines a liberalisation (no support) and regionalization (maximum support) scenario. In terms of policy options the paper shows that the structural change process in agriculture (measured in terms of agricultural share in GDP) is a long-term process that continues with or without policy changes.... |

| The Australian government is introducing a Carbon Pollution Reduction Scheme in 2010, as part of its climate change policy. After 2015 agriculture may be covered by this scheme. This paper examines how different broadacre farming systems may be affected by the policy settings of this scheme. Using the bio-economic farming systems model MIDAS (Model of an Integrated Dryland Agricultural System) the impacts of the Carbon Pollution Reduction Scheme on the profitability of different broadacre farming systems in the southwest of Australia are investigated. Results show a range of profit and enterprise impacts across the various farm types. In a scenario where agriculture is not covered by the scheme, reductions in profit range from 7 to 12 percent, attributable... |
