Abstract
In this article we investigate the determining factors of bank monitoring in small
business lending. Unlike previous studies that rely on proxies of a bank’s monitoring
effort, we use a large and unique data set that includes the number of monitoring contacts
per year between a European bank and a large number of small firms from 2009 to 2012.
Our main results highlight that the frequency of a bank’s monitoring effort is negatively
related to the firm’s reputation and the strength of the bank–firm relationship, and
positively related to the bank–borrower proximity and the borrower’s credit risk level.

I. Introduction
Monitoring has valuable implications for both banks (interested in reducing monitoring
costs for competitive strategies) and firms (which seek to lower their borrowing costs),
but it has received little attention in the empirical literature because of the difficulty in
obtaining data and establishing an effective measure of a bank monitoring efforts (see,
among others, Coleman, Esho, and Sharpe 2006; Akhigbe and McNulty 2011). In fact,
monitoring is a combination of collection and inspection of credit information that may
pertain to different organizational levels and to different bank internal processes. Banks
are reluctant to provide such data because of confidentiality problems and costs of
extraction.
To address these issues, several studies have proposed proxy measures of a
bank’s monitoring efforts, such as credit ratings (e.g., Billett, Flannery, and Garfinkel
1995), loan loss provisions (e.g., Johnson 1997), bank size (e.g., Cook, Schellhorn, and
Spellman 2003), and labor input in the monitoring process (see, among others, Coleman,

Esho, and Sharpe 2006; Lee and Sharpe 2009). Most studies treat all borrower firms as a
homogenous group and do not recognize that a bank’s efforts spent on monitoring may
also depend on borrower reputation, potential information asymmetries, or the
borrower–lender relationship. One exception is Blackwell and Winters (1997), who
use a supposed measure of monitoring frequency (extracted from policy and procedure
handbooks from a sample of six banks) to find that banks monitor smaller firms more
frequently than larger firms, highly leveraged firms more frequently than less leveraged
firms, and firms with which they have a shorter banking relationship more frequently than
those with a longer banking relationship.
We build on this research by investigat ing the correlation between actua l
measures of bank monitoring effor ts and a set of variables that include both tra ditional
and nontraditional monit oring determinants. Speci fically, we use a large and uniqu e
data set that includes the numbe r of monitoring contacts pe r year between a large
Italian bank and approxim ately 30,000 clients (smal l firms) over a four-year period
(2009–2012).
Our contribution to the literature is based on four major findings. First, we find
strong empirical evidence that banks allocate more review and monitoring time to higher
risk borrower firms than lower risk firms. Second, we find that the larger the geographical
distance between a firm and a bank, the lower the level of bank monitoring because the
increase in distance causes an increase in monitoring costs. However, the effect of
distance also depends on credit quality: as distance increases, the bank may raise its
quality standards and accept only better quality loans that need less monitoring. Third,
we find that relationship banking works as substitute for monitoring effort. In fact, we
observe that borrower firms that have a close relationship with the bank and a higher
reputation (measured by both the length of credit relationship and the number of products
sold by a bank over time) are, ceteris paribus, less monitored than other firms. Finally, we
find strong evidence for the free-rider hypothesis suggested by Diamond (1984), which
predicts that when monitoring is costly, multiple lending relationships may lead to a
duplication of cost efforts and imply a free-rider problem among lenders, which reduces
the amount of monitoring.
Together, these findings reveal whether monitoring activities are correlated to
both traditional proxies for monitoring costs as predicted by theory (e.g., number of
lenders, credit risk classifications) and other indirect measures of monitoring not
considered in previous research (i.e., distance and banking products). By doing this, our
article may help scholars conducting applied empirical research select the most
appropriate identification variable for monitoring when direct observations are
unavailable.
II. Monitoring Metrics: A Brief Review
Bank monitoring represents one of the most important issues in the finance literature. For at
least three decades researchers have examined: (1) why banks dedicate considerable
resources to monitoring activities (e.g., Fama 1985; Chan, Greenbaum, and Thakor 1986;
Diamond 1984, 1991; Qi 1998; Boot and Thakor 2000), (2) what impact bank monitoring
