The objective of this paper is to work out some fundamental dynamic effects on agricultural structure, farm incomes, and efficiency that result from decoupled income payments, the transfer of payments together with a progressive payment cut. To do so, we apply the agent-based model AgriPoliS...

The minority game (MG) is an agent-based model of a competing population with limited resources. We propose and study a modified model based on the MG in which the pool of strategies is biased, i.e., some strategies are more often picked by agents than others. It is found that the fluctuation in...

We define and study a market model, where agents have different strategies among which they can choose, according to their relative profitability, with the possibility of not participating to the market. The price is updated according to the excess demand, and the wealth of the agents is...

The crowd–anticrowd theory is applied to explain the features observed in a class of the minority game using different payoff functions. Simulations results using both the full strategy space and a reduced strategy space reveal that the standard deviation (SD) in the number of agents making a...

Complex systems can exhibit unexpected large changes, e.g. a crash in a financial market. We examine the large endogenous changes arising within a non-trivial generalization of the minority game: the grand canonical minority game. Using a Markov-Chain description, we study the many possible...

We present numerical and analytic results for a new version of the minority game (MG) in which strategy performance is recorded over a finite time horizon. The dynamics of this time horizon minority game (THMG) exhibit many distinct features from the MG and depend strongly on whether the...
