Improvements and Future Challenges for the Research Infrastructure in the Field “Experimental Economics”

Experimental economics is an established method of generating controlled and replicable empirical knowledge. It is complementary to other empirical methods in the social sciences. The research infrastructure for laboratory experiments is very good in Europe and also in Germany. One useful instrument would be to develop a short socio-economic questionnaire with questions already used in surveys that experimental economists could use to administer to their participants. The analyses of the selectivity of subject pools would then be an easy task. However, among experimental economists no standard exists yet, which limits the comparability of respective data sets. An effort shall be undertaken to “create” such a common questionnaire. The status quo with regard to data reporting is that no standard has emerged yet. There exists one data repository (in the United States) where data of experiments are collected and are freely available. Building up a data archive that integrates (merges) existing data is very laborious and requires substantial scientific inputs of interested researchers.Experimental economics, data archives, selectivity of subject pools

TRAVOS: Trust and Reputation in the Context of Inaccurate Information Sources

In many dynamic open systems, agents have to interact with one another to achieve their goals. Here, agents may be self-interested, and when trusted to perform an action for another, may betray that trust by not performing the action as required. In addition, due to the size of such systems, agents will often interact with other agents with which they have little or no past experience. There is therefore a need to develop a model of trust and reputation that will ensure good interactions among software agents in large scale open systems. Against this background, we have developed TRAVOS (Trust and Reputation model for Agent-based Virtual OrganisationS) which models an agent's trust in an interaction partner. Specifically, trust is calculated using probability theory taking account of past interactions between agents, and when there is a lack of personal experience between agents, the model draws upon reputation information gathered from third parties. In this latter case, we pay particular attention to handling the possibility that reputation information may be inaccurate

Against Marrying a Stranger Marital Matchmaking Technologies in Saudi Arabia

Websites and applications that match and connect individuals for romantic purposes are commonly used in the Western world. However, there have not been many previous investigations focusing on cultural factors that affect the adoption of similar technologies in religiously conservative non-Western cultures. In this study, we examine the socio-technical and cultural factors that influence the perceptions and use of matchmaking technologies in Saudi Arabia. We report the methods and findings of interviews with 18 Saudi nationals (nine males and nine females) with diverse demographics and backgrounds. We provide qualitatively generated insights into the major themes reported by our participants related to the common approaches to matchmaking, the current role of technology, and concerns regarding matchmaking technologies in this cultural con-text. We relate these themes to specific implications for designing marital matchmaking technologies in Saudi Arabia and we outline opportunities for future investigations.Comment: 11 pages, 1 table, DIS 201

Issues in the study of virtual world social movements

Virtual worlds are online three-dimensional worlds that are often constructed to look much like the real world. As more people begin to use these virtual worlds, virtual communities are emerging enabling various social activities and social interactions to be conducted online. Based on a literature review of social movements, virtual communities and virtual worlds, this paper suggests a framework to guide IS research into this new and exciting area

Trust and deception in multi-agent trading systems: a logical viewpoint

Trust and deception have been of concern to researchers since the earliest research into multi-agent trading systems (MATS). In an open trading environment, trust can be established by external mechanisms e.g. using secret keys or digital signatures or by internal mechanisms e.g. learning and reasoning from experience. However, in a MATS, where distrust exists among the agents, and deception might be used between agents, how to recognize and remove fraud and deception in MATS becomes a significant issue in order to maintain a trustworthy MATS environment. This paper will propose an architecture for a multi-agent trading system (MATS) and explore how fraud and deception changes the trust required in a multi-agent trading system/environment. This paper will also illustrate several forms of logical reasoning that involve trust and deception in a MATS. The research is of significance in deception recognition and trust sustainability in e-business and e-commerce

Creating agent platforms to host agent-mediated services that share resources

After a period where the Internet was exclusively filled with content, the present efforts are moving towards services, which handle the raw information to create value from it. Therefore labors to create a wide collection of agent-based services are being perfomed in several projects, such as Agentcities does. In this work we present an architecture for agent platforms named a-Buildings. The aim of the proposed architecture is to ease the creation, installation, search and management of agent-mediated services and the share of resources among services. To do so the a-Buildings architecture creates a new level of abstraction on top of the standard FIPA agent platform specification. Basically, an a-Building is a service-oriented platform which offers a set of low level services to the agents it hosts. We define low level services as those required services that are neccesary to create more complex high level composed services.Postprint (published version

Trust in the digital world - the return of the kings of old

Drawing principally on examples and literature from the Anglosphere, the author argues that the high salience given to "trust" and "trustworthiness" in recent scholarly literature, and which (notably in Putnam's work) attributes declining trust to a widely mistrusted mass media does not acknowledge the trustbuilding potential (realised in some instances) of interactive "Web 2.0" applications. Drawing on O'Neill's proposal that trust inheres in dialogue and mutual checking and verification, the author argues that "Web 2.0" media provide a variety of instances where the "dialogic" character of "Web 2.0" has established and enhanced trustworthiness. He argues normatively for a combination of "Web 2.0" interactivity and the adoption and implementation of self-regulatory codes in order to enhance the trustworthiness of the media
