This paper proposes a new approach to anonymous communication called information slicing. Typically, anonymiz-ers use onion routing, where a message is encrypted in layers with the public keys of the nodes along the path. Instead , our approach scrambles the message, divides it into pieces, and sends the pieces along disjoint paths. We show that information(More)

A holdout problem arises when a good owned by disparate sellers is desired by a buyer only in its entirety, as in land assembly. Market design is crucial in the presence of holdout, as fully respecting property rights of many sellers eliminates otherwise-efficient trade. We propose a Concordance principle, inspired by the Cournot (1838) theory of concours(More)

The maintenance of such a network requires significant(More)
BACKGROUND Participation bias is a well-known phenomenon in epidemiologic research, where individuals consenting to research studies differ from individuals who are not able or willing to participate. These dissimilarities may limit the generalizability of results of research studies. Quantification of the participation bias is essential for the(More)
