of the business case, we will analyze the value exchanges and extend the model
according to the guidelines proposed.
The first step in the analysis, according to guideline 1, is to identify the kinds of
rights involved in the value exchanges. The value exchange monetary loan means
that the borrower gets privileges and power rights on the money but also that there is
a duty for the borrower to return the money with an interest fee. In other words, the
pawnshop gets a claim on the borrower to pay back the loan, which is made explicit
in Fig. 10. According to guideline 3, we are also to introduce optional custody
provisions. In this case, the borrower gives custody of some goods to the pawnshop
as collateral. There is also a duty for the pawnshop to return the goods to the bor-
rower upon request, i.e. the borrower has a claim on the pawnshop, which is also

exchanges in which the borrower gets a loan, she leaves a good for collateral, the
pawnshop gets a claim on the borrower to pay back the loan, and the borrower gets
