La relation de clientèle banque-entreprise et la structure du pool bancaire dans un environnement corrompu : trois essais

Abstract : This thesis consists of three research on the firms’ bank financing. The first essay focuses the influences of bank–firm relationships and political connections on firms’ access to credit. It uses a manually collected data set of Vietnamese medium-sized enterprises to show that bank–firm relationships (length of relationship with main bank and number of banks) and political connections have complementary effects on maximizing firms’ availability of credit. This research has policy implications for emerging economies characterized by local government corruption; it suggests that policymakers should prefer transactional banking systems to relationship banking systems, and it exposes the dark side of bank–firm relationships. The second essay investigates the effects of political connections and local corruption on the structures of firms’ bank pools. Using the same data set with our first essay, it finds that politically connected firms tend to establish their main bank relationships with connected banks. It also finds that connected firms reduce their numbers of banks and their diversity of bank ownership types in their bank pools when they achieve main bank relationships with connected banks; such firms maintain these bank pool structures when corruption is prevalent in their home provinces. Results demonstrate that local corruption is associated positively with number of banks and diversification of bank ownership types. The last essay explores the structure of firms’ bank pools in emerging economies characterized by corruption. In the proposed theoretical model, firm managers maximize an expected utility function that depends on both firm value and personal consumption. According to the weight they assign to each component, managers choose among three bank pool structures to combine some number of banks and the choice of a main bank that is more or less corrupt. The test of this model relies on the same rich data set with our first essay. The results confirm that firms and banks match, in terms of their levels of integrity. Moreover, firms tend to increase the number of banks in the bank pool when they cannot achieve a relationship with a desirable main bank.
