This study empirically analyzes the effects of de jure financial openness on institutional quality as captured by indicators on investment risk, corruption level, impartiality of judiciary system, and the effectiveness of bureaucracy. We show that a higher degree of financial openness improves institutional quality mainly by reducing investment risks. We also study the effect of a single liberalization reform. Again, we find evidence for the beneficial impact of financial liberalization with the exception of corruption. We additionally show that the benign consequences of financial opening for the institutional development are even larger if financial liberalization is supported by simultaneous political liberalization, while financial deregulation in former socialist countries tends to worsen institutional quality.
