In this paper we explore query execution and storage management issues for Mariposa, a distributed data base system under construction at Berkeley. Because of the extreme complexity of both issues, we have adopted an under- lying economic paradigm for both problems. Hence, queries receive a budget which they spend to obtain their answers, and each processing site attempts to maximize income by buying and selling storage objects and processing queries for locally stored objects. This paper presents the protocols which underlie this economic system.
