Given the limitations of market mechanism and the government's role, neither the market nor the government is able to resolve the problem of overcapacity on its own. In resolving overcapacity, market and the government should play their respective roles rather than replace one another. While the market is a dominant force in regulating capacity and achieving supply and demand equilibrium, the government should provide institutional assurances for effective market operation. Market-based solutions to overcapacity require the government to provide institutional assurances and create a system where market entities decide to enter and exit the market under effective restraints and incentives with a clear boundary.展开更多

In the absence of appropriate safeguards, service users can still manipulate this feedback. Auction mechanisms have already addressed the problem of manipulation by market- trading participants. When auction mechanisms are applied to trust systems, their interaction with the trust systems and associated overhead need to be quantitatively evaluated. This paper proposes two distributed architectures based on centralized and hybrid computing for integrating an auction mechanism with the trust systems. The empirical evaluation demonstrates how the architectures help to discourage users from giving untruthful feedback and reduce the overhead costs of the auction mechanisms.展开更多

文摘The reputation-based trust mechanism is a way to assess the trustworthiness of offered services, based on the feedback obtained from their users.
