The success of policy-based credit programs in Japan and the Republic
of Korea suggests that credit policy can be an effective instrument fo
r economic development. Why, then, have credit policies failed in so m
any countries, and what factors explain their relative success in Japa
n and Korea? Both economic and institutional factors appear to be impo
rtant in the success or failure of credit policies. Essential economic
factors include a reliance on the private sector, a bias toward indus
trialization, an orientation toward export production, the encourageme
nt-of domestic competition, and a commitment to price stability. Cruci
al institutional factors include extensive and frequent consultation b
etween government and the private sector, effective monitoring systems
, and, most important, a clear and credible plait for economic develop
ment. Although several countries have included one or more of these fa
ctors in their programs, the experience of Japan and Korea suggests th
at a comprehensive-network combining all or most of these factors may
be necessary for the successful implementation of credit policies.
