A network growth mechanism based on a two-step preferential rule is investigated as a model of network growth in which no global knowledge of the network is required. In the first filtering step a subset of fixed size m of existing nodes is randomly chosen. In the second step the preferential...

This paper examines a search model in which knowledge is created as rational, but poorly informed, innovators obtain new ideas from combinations of existing ideas. We assume that the productivity of an idea is stochastic and depends on the productivity of the parental ideas. Importantly, we...

The representation of the economic system, from a complexity perspective, focuses on interactions among heterogeneous agents in conditions of uncertainty. Heterogeneity entails asymmetric reactions to shocks and, through interaction mechanisms and feedback loops at micro, macro and meso level,...

I present in this paper an integrated framework for structuring and evaluating dynamic and sequential climate change decision making in the international arena taking into account influence processes occuring during negotiation rounds. The analysis integrates imitation, persuasion and dissuasion...
