How Smart Should Farms Be Modeled? Behavioral Foundation of Bidding Strategies in Agent-Based Land Market Models

Kellermann, Konrad; Balmann, Alfons - International Association of Agricultural Economists - IAAE - 2006

Land markets play a crucial role in agricultural structural change. Because the dynamics of structural change and land markets, respectively, mainly depend on the interactions between individual farms, agent-based modeling (ABM) has been established as a tool for understanding and explaining...

Computability of simple games: A complete investigation of the sixty-four possibilities

Kumabe, Masahiro; Mihara, H. Reiju - Volkswirtschaftliche Fakultät, … - 2006

Classify simple games into sixteen "types" in terms of the four conventional axioms: monotonicity, properness, strongness, and nonweakness. Further classify them into sixty-four classes in terms of finiteness (existence of a finite carrier) and computability. For each such class, we either show...

Repulsive Particle Swarm Method on Some Difficult Test Problems of Global Optimization

Mishra, SK - Volkswirtschaftliche Fakultät, … - 2006

In this paper we test a particular variant of the (Repulsive) Particle Swarm method on some rather difficult global optimization problems. A number of these problems are collected from the extant literature and a few of them are newly introduced. First, we introduce the Particle Swarm method of...

Robust Estimators are Hard to Compute

Bernholt, Thorsten - Institut für Wirtschafts- und Sozialstatistik, … - 2006

In modern statistics, the robust estimation of parameters of a regression hyperplane is a central problem. Robustness means that the estimation is not or only slightly affected by outliers in the data. In this paper, it is shown that the following robust estimators are hard to compute: LMS, LQS,...
