structure of the securities. Each node has a method to value the securities located at
lower levels of the tree. The types of method are as follows:
• Immediately: The securities are evaluated independently.
• Query: A query to the SPV is required. If it is
Query
, the dependent slave agent is
activated and obtains the information, e.g. losses of the portfolio, from the agent
at the SPV.
The agent at the SPV that receives the query from the slave agent, checks the
collection of the debt, and reports the results. If the securities are repackaged, the
query is executed recursively.
The advantage of this scheme is that the queries from investors to servicers are
distributed.
12.7 A Local Currency System Reflecting Variety of Values
12.7.1 Background
The local currency is suitable for financial settlement between members of a
community. Several theoretical approaches have been studied to analyze the circu-
lation of local currencies. Katai et al. (
2009
) described the ability of local currencies
by introducing a method based on fuzzy network analysis. Miura (
2008
) explained
how local currencies circulate on the basis of the search theory of money. As these
previous studies treated the values as a criterion, just circulating resources in the
communities is insufficient to meet our aims. Muto (
2006
) developed theoretical
foundations of social motives in a dyad model from the viewpoint of altruism and
egalitarianism. This study evaluates the values and motives in a society.
