The revelation principle asserts that every outcome brought by a mechanism is realized by a truthful direct mechanism. The present paper investigates the regularity conditions of these two mechanisms in the continuous space of the agent’s type. It questions what regularity condition a general mechanism confers upon a direct mechanism through the revelation principle. By so doing, we elucidate t...

Thanks to the work of scholars such as Ulrich Luz and Dale C. Allison, Jr., Wirkungsgeschichte (usually rendered into English as “reception history”) has come to be regarded as a necessary part of biblical scholarship.1 Recent years have seen the publication of a volume on Revelation in the Ancient Christian Commentary on Scripture series, as well as of a book, authored by Judith Kovacs and Chr...

Geographically dispersed sellers in electronic reverse-marketplaces such as those hosted by Freemarkets are uncertain both about the number of opponents participating and their coststructure in any given market session. Over the course of several market sessions, they learn about the competitive structure of their market. How sellers learn to reduce the level of uncertainty is dependent on the ...

There is a large literature aimed at characterizing the social choice functions that can be implemented in Bayes Nash equilibria. This literature typically takes agents’information as exogenously given and …xed throughout the analysis. While for some problems this may be appropriate, the assumption is problematic for others. A typical analysis, relying on the revelation principle, maximizes som...

Classic direct mechanisms require full utility revelation from agents, which can be very difficult in practical multi-attribute settings. In this work, we study partial revelation within the framework of one-shot mechanisms. Each agent’s type space is partitioned into a finite set of partial types and agents (should) report the partial type within which their full type lies. A classic result im...
