ABSTRACT
This chapter explains the individual participant level, engaging transaction data from Hour Exchange Portland (HEP) and Community Exchange (CE) as well as our surveys from Member to Member (M2M). Time Banks are not the source for large numbers of trading partners for most members. The bonds that are formed among members are likely to be deeper than those gained from the average transaction in the formal economy. Most Time Bank exchanges are highly personal, while most formal economy transactions are very impersonal. At HEP, one-quarter of all members have been involved in only one hour's worth of service exchanges. At CE, this is much less frequent, with only 4" of members having exchanged only one hour. The computation of ego-network density only concerns the ties among the other members in the participant's network. The size of members' exchange networks within their Time Bank, their number of contacts.
