    Abstract: We present results of several experiments that deal with endogenous entry in auctions and auction valuation. One observation that is constant across all of the experiments we report is that laboratory subjects have a difficult time evaluating potential gains from auctions. Even after they are given some experience with particular auctions, the uncertainty inherent in the auctions (the probability of winning as well as the potential gains from winning) makes it difficult for subjects to compare different auction mechanisms. This highlights the need for new experimental procedures to be used for testing theories that involve endogenous auction entry in the laboratory.

    Abstract: Electronic reputation or "feedback" mechanisms aim to mitigate the moral hazard problems associated with exchange among strangers by providing the type of information available in more traditional close-knit groups, where members are frequently involved in one another's dealings. In this paper, we compare trading in a market with online feedback (as implemented by many Internet markets) to a market without feedback, as well as to a market in which the same people interact with one another repeatedly (partners market). We find that, while the feedback mechanism induces quite a substantial improvement in transaction efficiency, it also exhibits a kind of public goods problem that, unlike in the partners market, the benefits of trust and trustworthy behavior go to the whole community and are not completely internalized. We discuss the implications of this perspective for improving feedback mechanisms.
