Granting collateral to secure loans is a prominent feature of the U.S.
economy, but, surprisingly, we do not understand how borrowers and le
nders decide whether to engage in a secured or an unsecured transactio
n in this Article, Professor Mann argues that existing theories of sec
ured lending are inadequate because the theories' predictions have not
been tested against empirical data. To understand the actual pattern
of secured credit, Professor Mann interviewed more than twenty borrowe
rs and lenders in various sectors of the economy. Based on the evidenc
e gathered in these interviews, as well as on preexisting empirical st
udies, this Article develops a model of the borrower's decision to gra
nt collateral that focuses on the borrower's perceptions of the costs
and benefits of secured and unsecured transactions. Granting collatera
l lowers the aggregate costs of a lending transaction by lowering the
pre-loan perception of the risk of default. Secured credit can do this
not only by increasing the lender's ability to collect the debt forci
bly through liquidation of the collateral, but also in less direct way
s: by decreasing the borrower's ability to obtain subsequent loans; by
increasing the lender's leverage over the borrower's activities; and
by repairing the loan-induced differentiation of the incentives of the
borrower and the lender. Conversely a grant of collateral can increas
e the costs of a lending transaction by increasing the costs of enteri
ng the transaction as well as the costs of administering the loan. in
the Article's final section, Professor Mann uses the decision-bared mo
del to erp[ain three separate aspects of the Pattern of secured credit
: the relatively infrequent use of secured credit by companies with st
rong financial records, the relation between the use of collateral and
the duration of the debt, and the apparently low rate of retention of
security interests by suppliers.
