This paper examines the relationship between the development of financial s
ystems and economic growth using Korea as a case study. In particular, we f
ocus on the relative development of financial intermediaries and capital ma
rkets, and their impact on the portfolio behavior of the household and busi
ness sectors. Causality and non-nested model selection tests show that fina
ncial development in general leads economic growth and that financial inter
mediaries are more important than capital markets in this relationship. (C)
