The aim of this paper is to simulate profit expectations as an emergent property using an agent based model. The paper builds upon adaptive expectations, interactive expectations and small world networks, combining them into a single adaptive interactive profit expectations model (AIE)....

The focus of this study is on black markets which provide an important segment of the parallel economy. These markets operate in disequilibrium,search and information costs become very important.Trafficking in drugs taken as case, to explore both theoretically and empirically. The problem,...

Land, labor, indigenous knowledge and institutional resources of producers in the Central Highlands of Ethiopia are investigated. Frequency distribution and comparative statistical analysis of the two regions with respect to these and other parameters suggest that in a situation where all...

The aim of this paper is to interpret the relationships between information networks and the civil wars (Colombia). Over a period of paramilitary violence networks of informants were used with a strategic purpose. In fact, the paramilitaries were preparing each slaughter counting information...

We review theory and evidence relating to herd behaviour, payoff and reputational interactions, social learning, and informational cascades in capital markets. We offer a simple taxonomy of effects, and evaluate how alternative theories may help explain evidence on the behavior of investors,...

Information sources, creation of informant networks and labors of local intelligence have become very important goals in political power calculations of the paramilitary and insurgents. Phenomena of information and rumor can disclose central aspects to understand the direction of events yet to...

We study a coordination problem where agents act sequentially. Agents are embedded in an observation network that allows them to observe the actions of their neighbors. We find that coordination failures do not occur if there exists a sufficiently large clique. Its existence is necessary and...

The aim of this paper is to interpret the relationships between information networks and the civil wars (Colombia). Over a period of paramilitary violence networks of informants were used with a strategic purpose. In fact, the paramilitaries were preparing each slaughter counting information...

We introduce a heterogeneous connection model for network formation to capture the effect of cost heterogeneity on the structure of efficient networks. In the proposed model, connection costs are assumed to be separable, which means the total connection cost for each agent is uniquely...

DISCURSIVE NORMS IN BLOGGING Abstract The article proposes an empirical research of blogging practices associated with the negotiation of the community identity. The data are verbal exchanges on Victor Ciutacu’s blog “Vorbe Grele” [“Harsh Words”]. The participants in blogging reveal...
