Two theories of endogenous money: an empirical study of Korea

Abstract

This study tests Korea’s two endogenous money supply channels: the accommodationist and structuralist channels. The main analytic tools are the Fully Modified OLS, Maki’s structural break test, Error Correction Model, and Impulse Response Function (IRF) analysis. The primary purpose of this study is to propose analytical methods to compare the two endogenous money supply channels. The analytic models also consider the impact of fiscal policy and the current account balance on reserves. The test results reveal a unilateral causality from loan to reserve and a bilateral causal relationship between loan/reserve and Lf/deposit ratio. These results suggest that both accommodationist and structuralist channels coexist in Korea. However, the structuralist channel explains a relatively small portion of the endogenous money supply process. The IRF analysis does not provide evidence for the pressure on the interest rate spread exerted by financial institutions’ portfolio adjustment. This result can be attributed mainly to the central bank’s growing accommodative attitude toward the reserve demand.
