The policy relevance of the QR approach builds on the motivation that blanket policies on the role of information sharing in financial development may not be effective unless they are contingent on initial levels of financial development and tailored differently across countries with low, intermediate and high levels of financial development. Information sharing is measured with private credit bureaus (PCB) and public credit registries (PCR) while financial development is proxied with dynamics of depth, efficiency, activity and size. The following findings are established. First, for financial depth, while there is a positive threshold effect from PCR in money supply and liquid liabilities, the effect from PCB is mixed. Second, for financial efficiency, there is a: (i) contemporary positive threshold from PCR and mixed effect from PCB in banking system efficiency and (ii) U-shape and positive threshold from PCR and PCB respectively in financial system efficiency. Third, for financial activity, there are consistent positive thresholds from PCR and PCB in banking system activity and financial system activity. Fourth, there are negative thresholds from PCR and PCB in financial size. Positive thresholds are consistent incremental financial development rewards from PCR and/or PCB with increasing financial development and vice-versa for negative thresholds.

Findings – Four main findings are established. First, education improves financial depth and financial efficiency but mitigates financial size. Second, apart from a thin exception (trade’s incidence on money supply), economic incentives (credit facilities and trade) are not consistently favorable to financial development. Third, information and communications technology improves only financial size and has a negative effect on other financial dynamics.
