Abstract
Does the mere presence of big banks affect macroeconomic outcomes? In this paper, we develop a theory of granularity (Gabaix, 2011) for the banking sector, introducing Bertrand competition and heterogeneous banks charging variable markups. Using this framework, we show conditions under which idiosyncratic shocks to bank lending can generate aggregate fluctuations in the credit supply when the banking sector is highly concentrated. We empirically assess the relevance of these granular effects in banking using a linked micro-macro dataset of more than 80 countries for the years 1995-2009. The banking sector for many countries is indeed granular, as the right tail of the bank size distribution follows a power law. We then demonstrate granular effects in the banking sector on macroeconomic outcomes. The presence of big banks measured by high market concentration is associated with a positive and significant relationship between bank-level credit growth and aggregate growth of credit or gross domestic product.

The Impact of Competition on Bank Orientation

Abstract
How do banks react to increased competition? Recent banking theory significantly disagrees regarding the impact of competition on bank orientation—i.e., the choice of relationship-based versus transactional banking. We empirically investigate the impact of interbank competition on bank branch orientation. We employ a unique data set containing detailed information on bank–firm relationships. We find that bank branches facing stiff local competition engage considerably more in relationship-based lending. Our results illustrate that competition and relationships are not necessarily inimical.

Distance, Lending Relationships, and Competition
Hans Degryse, Steven Ongena

No. 1,

Abstract
We study the effect on loan conditions of geographical distance between firms, the lending bank, and all other banks in the vicinity. For our study, we employ detailed contract information from more than 15,000 bank loans to small firms comprising the entire loan portfolio of a large Belgian bank. We report the first comprehensive evidence on the occurrence of spatial price discrimination in bank lending. Loan rates decrease with the distance between the firm and the lending bank and increase with the distance between the firm and competing banks. Transportation costs cause the spatial price discrimination we observe.

Relationship Lending within a Bank-Based System: Evidence from European Small Business Data

Journal of Financial Intermediation,
No. 1,
2000
Abstract
We investigate relationship lending using detailed contract information from nearly 18,000 bank loans to small Belgian firms operating within the continental European bank-based system. Specifically, we investigate the impact of different measures of relationship strength on price and nonprice terms of the loan contract. We test for the possibility of rent shifting by banks. The evidence shows two opposing effects. On the one hand, the loan rate increases with the duration of a bank–firm relationship. On the other hand, the scope of a relationship, defined as the purchase of other information-sensitive products from a bank, decreases the loan's interest rate substantially. Relationship duration and scope thus have opposite effects on loan rates, with the latter being more important. We also find that the collateral requirement is decreasing in the duration of the relationship and increasing in its scope.
