This paper presents the application of the sensitivity analysis techniques Design of Experiments (DOE) and metamodelling to the agent-based model AgriPoliS, which is a spatial and dynamic simulation model of regional structural change. DOE and metamodelling provide a more systematic analysis 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...

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...

Agent-based models have recently become very popular. However, it is often difficult to communicate the models' complexity and assumptions. Hence, criticising them becomes a challenging task. This paper addresses this problem and discusses different ways to increase the transparency and...

This paper explores the impacts of modulation as suggested by the EU Commission (“Preparing for the “Health Check” of the CAP reform”, 2007). The agent-based model AgriPoliS has been adapted to the case study region Ostprignitz-Ruppin (Brandenburg, Germany). Impacts on farm structures,...

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...

This paper analyses the interplay between farm adjustments on individual farms in dualistic farm structures over time using an agent-based simulation approach. In particular, explore the development of individual farms when there are off-farm work opportunities and different propensities of...

More powerful computers, the better availability of micro-data, and the development of new modeling techniques, such as multi-agent systems, allows to analyze agricultural policies from the bottom up. We present such an approach that considers the spatial interaction of thousands of individually...

"This paper investigates the dynamic interplay between farm exit and entry of single-holder farms (SF) in a dualistic farm structure in the Nitra region of the Slovak Republic. Our focus is on economic and noneconomic reasons for farm exit. The impact of varying both the likelihood of succession...
