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...

The rapid ascent of commodity prices between late 2005 and 2008 led to renewed debate about what drives the demand and supply for basic food commodities. This paper examines the supply response to the output prices shocks for 22 commodity products in 3 regions of Switzerland by using a dynamic...

An empirically-based approach was developed to forecast the use of family labour, external labour, contractors and off-farm work in the agentbased sector model SWISSland. The forecast was based on a two-phase procedure. In the first phase, a Bayesian network was used to estimate the agents’...

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...
