We consider the effects a public revelation of information (e.g. rating, grade) has on trading in a dynamic signaling model. Competing buyers offer prices to a privately informed seller who can reject them and delay trade. Delay is costly and the seller has no commitment to its duration. The external public information allows for signaling in equilibrium. More interestingly, we characterize the...

This study examined the effects of different levels of identity revelation in relation to aspects most relevant to engaged online learning activities. An online learning system supporting question-generation and peer-assessment was adopted. Three 7 grade classes (N=101) were assigned to three identity revelation modes (real-name, nickname and anonymity) and observed for six weeks. A pretest-pos...

The effects of preference revelation on allocational and Pareto efficiency are studied in a multi-attribute reverse English auction. Multi-attribute reverse auctions have been proposed as market institutions for electronic request for quotation buying processes. Preference revelation is a crucial question in multi-attribute reverse auctions in terms of the efficiency of auction outcomes. Result...

Presuming of the validity of the Revelation Principle, the optimal (direct) mechanism with audit requires a two-part tariff to be offered to the agent, which weakens the ex ante incentives for effort. We then esta...
