This paper explores the causality between concentration in the banking industry and economic growth. Two empirical tests are performed for Italy over the period 1991–2001: the first one is a standard Granger-Sims causality test, the second one studies the direction of causality by taking into account the impact of changes in banks' internal and external factors on their own market shares. The results show that in the short-run economic growth is predominantly caused by banking consolidation, while in the long-run a reverse causation direction emerges, so that economic expansions tend to reduce market shares and thus favour a stronger competition in the industry.

Abstract
This paper explores the causality between concentration in the banking industry and economic growth. Two empirical tests are performed for Italy over the period 1991–2001: the first one is a standard Granger-Sims causality test, the second one studies the direction of causality by taking into account the impact of changes in banks' internal and external factors on their own market shares. The results show that in the short-run economic growth is predominantly caused by banking consolidation, while in the long-run a reverse causation direction emerges, so that economic expansions tend to reduce market shares and thus favour a stronger competition in the industry.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
