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...

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...

A central criticism common to agricultural economic modelling approaches for policy analysis is that they do not adequately take account of a number of characteristic factors of the agricultural sector. This concerns aspects like the immobility of land, heterogeneity of farms, interactions...

The objective of this paper is to work out some fundamental dynamic effects on agricultural structure, farm incomes, and efficiency that result from decoupled income payments, the transfer of payments together with a progressive payment cut. To do so, we apply the agent-based model AgriPoliS...

This paper investigates the relationship between structural change in agriculture and a policy regime switch at the regional level. Using the agent-based spatial and dynamic simulation model AgriPoliS, we simulate structural change for two different farm structures in response to a policy...

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,...

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...

"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...

Due to Germany’s specific farm structure, the progressive modulation of direct payments decided within the Health Check of the Common Agricultural Policy (CAP) is of particular relevance for German agriculture. In this paper we apply the agent-based model AgriPoliS to shed some light on the...
