It is notable that not all previous studies have found positive effects
of credit information sharing. Based on a natural experiment
in Argentina, where the public credit registry was expanded to all
firms, the study of Hertzberg et al. (2011) documents an amplification
of coordination effects among lenders when negative credit
information was shared in response to the credit registry reform.
This study is one of the rare that documents significant negative
real effects after the introduction of credit information. Thus, it is
ex ante not clear whether and under which conditions a positive
or negative effect prevails.
