This paper investigates the relationship between information technology, information sharing and bank lending in 99 countries from 2005 to 2008. Information technology-related costs contain the expenses from communication costs during customer relationship management activities. Credit information-related costs measure the costs for collecting borrowers' credit information. The empirical results show that advancements in technology improvement are positively correlated with larger foreign claims and domestic lending. This implies that a reduction of information costs results in an enlargement of credit markets' scale. However, the impacts from credit information sharing on domestic lending depend on the measures of information sharing. No significant relationship is found between information sharing and foreign claims.
