Structural change and farm labour adjustments in a dualistic farm structure: a simulation study for the region Nitra in southwest Slovakia

Schnicke, Hauke; Happe, Kathrin; Sahrbacher, Christoph - Leibniz-Institut für Agrarentwicklung in … - 2007

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...

Future and Past Effects of the Common Agricultural Policy in Czech Republic

Sahrbacher, Christoph; Jelinek, Ladislav; Kellermann, Konrad - European Association of Agricultural Economists - EAAE - 2007

The paper discusses the impact of the implementation of the EU Common Agricultural Policy on Czech agriculture with a special emphasis given to the effects resulting from the application of current direct payments system. Two approaches were applied: in an ex post analysis we address how...

Incentives and coordination in vertically related energy markets

Micola, Augusto Rupérez; Banal Estañol, Albert; Bunn, … - 2006

We present an agent-based model of a multi-tier energy market including gas shippers, electricity generators and retailers. We show how reward interdependence between strategic business units within a vertically integrated firm can increase its profits in oligopolistic energy markets. The...

Is Your Model Susceptible to Floating-Point Errors?

Izquierdo, Luis R.; Polhill, J. Gary - In: Journal of Artificial Societies and Social Simulation 9 (2006) 4, pp. 4-4

This paper provides a framework that highlights the features of computer models that make them especially vulnerable to floating-point errors, and suggests ways in which the impact of such errors can be mitigated. We focus on small floating-point errors because these are most likely to occur,...

Self-Organizing Traffic at a Malfunctioning Intersection

Kumar, Sujai; Mitra, Sugata - In: Journal of Artificial Societies and Social Simulation 9 (2006) 4, pp. 3-3

Traffic signals and traffic flow models have been studied extensively in the past and have provided valuable insights on the design of signalling systems, congestion control, and punitive policies. This paper takes a slightly different tack and describes what happens at an intersection where the...

Aid Competition - a Simple Agent-Based Model of Competition for Financial Aid

Margitay-Becht, András - In: Interdisciplinary Description of Complex Systems - … 4 (2006) 2, pp. 89-101

The research into the effectiveness of financial aid is gaining momentum lately. Some say it is ineffective, some say it could be effective, but all seem to agree that some of its aspects are currently unmapped. This article aims at showing a rather simplistic agent-based model that might hint...

Impact of the CAP Reform on Small-Scaled Grassland Regions in Bavaria, Germany

Roeder, Norbert; Kantelhardt, Jochen; Kapfer, Martin - International Association of Agricultural Economists - IAAE - 2006

The CAP reform of 2003 will change farmer's business environment in Europe. This paper analyses the impact of the reform on the land use in southern German grassland regions. The assessment will be based on model calculations for two typical grassland regions. Each study area represents one...

Collective Social Dynamics and Social Norms

Fent, Thomas - Volkswirtschaftliche Fakultät, … - 2006

How individual behaviour is determined or at least influenced by social norms is one of the classic questions of social theory. We consider a norm as a rule guiding individual decisions concerning rituals, beliefs, traditions, and routines. Whenever coordinated behaviour is enforced without the...

Impact of the CAP reform on small-scale grassland regions

Roeder, Norbert; Kantelhardt, Jochen; Kapfer, Martin - In: German Journal of Agricultural Economics 55 (2006) 5/6

This paper presents a regional land-use model that conceives farms as independent agents aiming at maximum individual utility. Farm agents optimize their utility with the help of a linear-programming algorithm that takes into account natural, economic and personal restrictions. Interactions...
