In recent years, Peer-to-Peer (P2P) systems and computational Grids are evolving into a new distributed computing model, called P2P Grid. This paper presents a new approach to solving the trust and security problems in a P2P Grid. Establishing trust in P2P Grids is essential to build lasting working relationships among the peers joining collective Grid applications. A P2P reputation system is t...

The role of decentralized trust and reputation management in the establishment of trust relationships between peers in decentralized applications has been well-recognized. Several reputation-based trust models exist in the literature. PACE is an architectural style for decentralized trust management. PACE provides specific principles that guide the incorporation of trust and reputation models w...

We analyze positive and negative campaigning in primary and general elections. Positive campaigning builds a candidate’s reputation, while negative campaigning damages a rival’s. We provide explanations for why general campaigns are more negative: in the general election, winning primary candidates benefit only from positive primary campaigning; and negative campaigning by a primary loser impai...

In this paper, we explore how a firm’s reputation affects both the reaction of the market to that firm’s product defects, as well as the firm’s learning response. In contrast to a variety of arguments set out by information economists and market sociologists claiming that reputation serves as an organizational asset, we explore the possibility that reputation can be an organizational liability....
