| A central criticism common to agricultural economic modelling approaches for policy analy-sis is that they do not adequately take account of a number of characteristic factors of the agri-cultural sector. This concerns aspects like the immobility of land, heterogeneity of farms, in-teractions between farms, space, dynamic adjustment processes as well as dynamics of struc-tural change. In brief, modelling the complexity of the system has not been at the centre of interest. In terms of modelling complex economic systems, an agent-based modelling ap-proach is a suitable approach to quantitatively model and understand such systems in a more natural way. In the same way, this applies to the modelling of agricultural structures. In par-ticular, agent-based... |

| The development of competitive and efficient agricultural structures has been one of the central goals of agricultural policy making in addition to ensuring a fair standard of living for farmers. To achieve these goals, the agricultural sector in most industrialised nations has long been the subject of government interven-tions. However, many agricultural policies have worked counteractively to these goals by creating distortions in the use of resources. Against this background, the emergence of new and innovative modelling methods such as agent-based models, in addition to ever-increasing computing capacities has offered new possibilities to model adjustment reactions and to quantify the impact of agri-cultural policies. This thesis takes up these new... |

| The paper analyses various forms of direct payments using the agent-based model AgriPoliS. The model is fitted to the agricultural region 'Hohenlohe' in Baden-Württemberg which is characterised by intensive livestock farming. The policy simulations show that decoupled payments which are attached to land do not have significant effects on structural change, competitiveness, and income as compared to the current Agenda 2000 policy. In order to reach a significant and lasting effect on the competitiveness of agriculture direct payments would have to be granted independently of production, land use, and farming activity in general. In order to ensure a sufficient degree of land management, area payments should be decreased to an extent which is just necessary... |

| Since the late 1980s, agriculture in Central and Eastern European Countries (CEECs) has been under considerable adjustment pressure due to changing political, economic and institutional environments. These changes have been linked to the transition process, as well as the ongoing integration into the European Union and the world market. Reduced subsidies, increased environmental and food quality demands, as well as structural changes in the supply, processing and food retailing sector call for major structural adjustments and the improvement of farmers’ managerial abilities. Though such changes always carry significant threats to farms, they also offer new opportunities for the farms' entrepreneurial engagement. Upcoming changes in the agricultural... |

| Agricultural structures have been shaped by a variety of factors including economic, cultural, historical, political, technological, and geographical conditions. Moreover, agricultural structures are not static. Structural change can be characterised as an evolutionary process consisting – among other things – of constant adjustment to changes in demand, supply, and technological progress. The development of competitive and efficient agricultural structures has been one of the central goals of agricultural policy making in addition to ensuring a fair standard of living for farmers. To achieve these goals, the agricultural sector in most industrialized nations has long been the subject of government interventions. However, many agricultural policies have... |

| The Deliverable 2.1 (D2.1) of the SCARLED project provides the conceptual framework for analysing structural change in agriculture and rural livelihoods in the NMS and established Member States of the EU. It concisely summarizes the underlying theories and concepts of the pertinent research issues in SCARLED. SCARLED addresses a topic of wide interest with regard to the identification of past and future key social and agricultural restructuring processes for a living countryside in the NMS. Methodologically, the topic is approached by comparative, structured multi-country farm surveys complemented by an analysis of structural changes in the farm sectors of two selected regions with the agent-based simulation model AgriPoliS, taking special account of... |

| The paper analyses various forms of direct payments using the spatial and dynamic model AgriPoliS. In AgriPoliS farms are represented as agents which act and interact individually. This allows for endogenous structural change. The model is fitted to the agricultural region 'Hohenlohe' in Baden-Württemberg which is characterised by intensive livestock farming. The policy simulations show that the fixing of a single income payment and coupling it to the farming of land - as it has been proposed by the EU Commission in the mid-term review - does not have significant effects on structural change, competitiveness, and income as compared to the current Agenda 2000 policy. In order to reach a significant and lasting effect on the competitiveness of agriculture, a... |

| During the last decade a new modeling approach, known as agent-based modeling, was developed and made its way into several areas of research. It greatly benefited from rapid developments in computing technology. As for economics, agent-based modeling is based on the observation that social systems can be understood and modeled explicitly as systems of interacting agents. Because of their flexibility with respect to the representation of agents, the interactions between agents as well as the resulting dynamic and spatial relationships, these models offer a great variety of perspectives for future research. In this contribution, the underlying modeling concept is presented, and exemplary applications to the field of sector and policy analysis are discussed.... |
