A methodology of comparative analysis of evolutionary models is proposed. The main aim of this proposition is to identify to what extend different models can be called ‘evolutionary ones’. Each model is analysed by searching for answers to following questions:  Is the model dynamical one?...

Experimental results on the ultimatum game show clearly that (1) large fractions of players offer a 'fair' allocation and (2) that unfair (but positive) offers are systematically rejected. We offer an explanation of this behavior using the 'indirect evolutionary approach' which is based on the...

We present a simple model of spatial evolution that avoids several problems that arise with more complex networks of players. We consider a world where pairs of players are matched forever. These players learn from the whole population but they are more likely to learn to strategies used by...

We introduce a generalized theoretical approach to study imitation models and subject the models to rigorous experimental testing. In our theoretical analysis we find that the different predictions of previous imitation models are due to different informational assumptions, not to different...

Transaction Costs Theory has been considered the 'new orthodoxy' in the theory of the firm, being this the very same reason for wide criticism by different schools of economic thought. However, there seems to be signs of complementarity between TCT and evolutionary approaches to the firm. Some...

Agent-based computational economics (ACE) is the computational study of economies modelled as evolving decentralized systems of autonomous interacting agents. A key focus of ACE research is understanding how global regularities arise from the bottom up, through the repeated local interactions of...

Meta-rules, or rules for making rules, determine the costs of innovation and thus the pace of economic growth. Adapting rules to a changing economic environment through explicit, well-designed meta-rules makes economic growth quicker, less painful, and more certain than adapting rules through...

In July 2003 a new Road Code was approved by the Italian parliament. Among many reforms whose validity is not questioned here, the new law states that on three-lane motorways the right lane should not be reserved anymore to slow vehicles alone. As in two-lane roads, all vehicles must now drive...
