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 acceptability of complex models. We use designed experiments and metamodelling to show relationships between model parameters and the impact of policy options. We do so using the model AgriPoliS which has been initialised using an artificial agricultural structure Agentenbasierte Ansätze erfreuen sich einer immer größeren Beliebtheit. Allerdings besteht ein grundlegendes Problem dieses Ansatzes darin, dass die Komplexität der angewendeten Modelle und der darin getroffenen...

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...

This Discussion Paper explores interactions between structural impediments to labour adjustment, specific labour adjustment patterns and the impacts of differing economical and political frames. Based on the agent-based simulation framework AgriPoliS adjusted to the agricultural structure of the region Nitra in southwest Slovakia, we carry out a range of simulation experiments on the possible interplay between off-farm job opportunities for farm operators, growth in other sectors of the economy, and policy impacts. Results show that free movement of labour between sectors leads to strong adjustments in the agricultural labour force and benefits farms with a growth potential. EU Accession and a subsequent decoupling of payments lead farms to stay in...
