Norms are essential to extend inference: inferences based on norms are far richer than those based on logical implications. In the recent decades, much effort has been devoted to reason on a domain, once its norms are represented. How to extract and express those norms has received far less attention. Extraction is difficult: as the readers are supposed to know them, the norms of a domain are s...

Certain statistical aspects of social systems are described by appropriately defined quantities named social potentials. Relations between social potentials are postulated by drawing an analogy with thermodynamics relations between thermodynamic potentials, thus obtaining a toy model of some of the statistical properties of social systems. Within this model, an interpretation of a socially rele...

Behavior in social groups follows unwritten codes, with the social group one is embedded in defining what behavior is acceptable and what is not. Prior research has found strong tendencies toward informational isomorphism in groups in online social networks, as social peers seem to establish a shared understanding of what behavior is acceptable and what informational content is okay to share. H...

The behavioural response with respect to actuarial adjustments in the German public pension system is analysed. The introduction of actuarial adjustments serves as a source of exogenous variation to estimate discrete time transition rates into retirement. The analysis is conducted on administrative data from social security records and on survey data in a comparative scenario. Probability mass ...

social norms are rules and expectations by which a society guides the behavior of its members based on the process of social control, the level of political legitimacy and procedural justice practices in the areas of governance, social order is guaranteed. in this study, the independent variables associated with three domains of social control, procedural justice and social capital to norm comp...

Machine learning is the core of artificial intelligence. Letting machine learning be driven not only by individual goals, but by goals consistent with those of a coalition of agents, is very difficult. Successful inductive rules for agent behaviour are typically based on machine guesses, the quality of which are measured in terms of precise real numbers representing utility. Random guesses are ...

This paper examines the role of other-regarding behavior as a mechanism for the establishment and maintenance of cooperation in resource use under variable social and environmental conditions. By coupling resource stock dynamics with social dynamics concerning compliance to a social norm prescribing non-excessive resource extraction in a common pool resource, we show that when reputational cons...

In social mechanism design, norm negotiation creates individual or contractual obligations fulfilling goals of the agents. The social delegation cycle distinguishes among social goal negotiation, obligation and sanction negotiation and norm acceptance. Power may affect norm negotiation in various ways, and we therefore introduce a new formalization of the social delegation cycle based on power ...
