This study evaluates linear programming (LP) and positive mathematical programming (PMP) approaches for 3,400 farm-level models implemented in the SWISSland agent-based agricultural sector model. To overcome limitations of PMP regarding the modelling of investment decisions, we further...

This paper analyses the impact of tradable and non-tradable single farm payment (SFP) entitlements for farm successors on structural change and the lease market. Using the example of Swiss agriculture, the effects on rental-price trends and farm-exit rates are investigated. An ex-ante normative...

The Swiss agent-based model (SWISSland) claims to depict as realistically as possible the 50 000 family farms comprising the whole of Swiss agriculture in all their heterogeneity as regards farm and cost structures as well as farm decision-making behaviour and interactions, with the aim of...

Das Agentenbasierte Agrarsektormodell SWISSland erhebt den Anspruch, Strukturwandelprozesse in der Schweizer Landwirtschaft möglichst realitätsnah zu beschreiben. Dieser Beitrag zeigt, dass Hofübernahme- und -aufgabeentscheidungen und dessen Auswirkungen auf den strukturellen Wandel in der...

The development of multi-agent models for agriculture has allowed the inclusion of farm decision-making behaviour and interactions in the simulation of smaller agricultural regions. Important methodological impact for this has come in particular from scientists from Germany. Currently under...

Mit der Entwicklung von Multiagentenmodellen für die Landwirtschaft konnten betriebliche Entscheidungsverhalten und Interaktionen in die Simulation von kleineren Agrarregionen einbezogen werden. Wichtige methodische Impulse dazu kamen insbesondere von Wissen-schaftlerinnen und Wissenschaftlern...

As the most intensive form of partnership in agriculture, farming collectives (FCs) place high demands on their participants. Based on a census of Swiss farming collectives, three success indicators are formed. The first and second describe interpersonal and economic success respectively, whilst...

The increasingly stringent conditions underlying Swiss dairy production demand sustainable milk production systems that are economically optimized but also meet the ecological requirements of society. To determine such systems, a comparative-static LP model was constructed at farm level....
