Understanding consumer behaviour is of vital importance to consumer-oriented e-business models today. In this paper, we study the relationships between consumer perceptions of risk and trust and the attitude towards purchasing at a consumer-to-consumer electronic marketplace (EM). Typical for EM settings is that consumer behaviour is subject to perceptions(More)
In this paper we present a generic model of trust for electronic commerce. The basic components of the model are party trust and control trust. We argue that an agent's trust in a transaction with another party is a combination of the trust in the other party and the trust in the control mechanisms for the successful performance of the transaction. The(More)
After arguing about the crucial importance of trust for Agents and MAS, we provide a definition of trust both as a mental state and as a social attitude and relation. We present the mental ingredients of trust: its specific beliefs and goals, with special attention to evaluations and expectations. We show the relation between trust and the mental background(More)
In this paper, we describe how an agent's trust in transactions is a combination of an agent's trust in the other party and the trust in the control mechanisms for the successful performance of the transaction. This distinction is, in particular, relevant for international business-to-business electronic commerce, where trading partners often do not know(More)
In this paper we introduce Prohairetic Deontic Logic (PDL), a preference-based dyadic deontic logic. In our preference-based interpretation of obligations " α should be (done) if β is (done) " is true if (1) no ¬α∧β state is as preferable as an α∧β state and (2) the preferred β states are α states. We show that this representation solves different problems(More)
In this paper we propose a semantics for dyadic deontic logic with an explicit preference ordering between worlds, representing diierent degrees of ideality. We argue that this ideality ordering can be used in two ways to evaluate formulas , which we call ordering and minimizing. Ordering uses all preference relations between relevant worlds, whereas(More)
Given the uncertainty of the online environment, institutional trust is fundamental in building and retaining online interorganizational relationships. The authors propose two types of institutional trust (a) third-party institution-based trust, which deals with intermediary driven structures, such as those in online B2B marketplaces, and (b) bilateral(More)

In this paper, we give formal analyses of notions of fraud for the aim of verification of trade procedures. A fraud possibility is seen as an undesirable property of a trade procedure which its specification should not satisfy. It is argued that fraud may occur (in a trade procedure) when an agent violates an obligation and he/she also deceives another(More)
