can be also played by several players on the closed market, with or without information about reputation. Other interesting games are e.g. binary-choice trust games, the gift-exchange game and various other forms of social games. Specifically games based on the Prisoner's Dilemma are popularly used to link trust with economic utility and demonstrate the rationality behind reciprocity. The popularization of e-commerce opened the discussion of trust in economy to new challenges while at the same time elevating the importance of trust, and desire to understand customer decision to trust. For example, interpersonal relationships between buyers and sellers have been disintermediated by the technology, and consequentially required improvement. Websites can influence the buyer to trust the seller, regardless of the seller's actual trustworthiness (e.g.). Reputation-based systems improved on trust assessment by allowing to capture the collective perception of trustworthiness, generating significant interest in various models of reputation.

By having a conveniently organized area to work on, concentration will increase as well as effort. Management and organization science scholars have also paid attention to how trust is influenced by contracts and how trust interacts with formal mechanisms. Parallel to the very large interest in trust, scholars in management and related disciplines have made the case for the importance of distrust as a related but distinct construct. Since the mid-1990s, a substantial body of organizational research has fallen into one of two distinct but nonexclusive paradigms of trust research. The first paradigm distinguishes between two major dimensions of trust.
