Abstract

This paper first shows an empirical result of VAR that Korean economy has experienced a severe economic contraction to an exogenous country spread shock. To analyze the effect of alternative monetary policy on the economy, the paper sets up a multi-sector small open economy new Keynesian (NK hereafter) model with financial frictions due to asymmetric information between firms and financial intermediaries along the line of Bernanke et al. (1999). It shows that the small economy with financial frictions is more vulnerable to the exogenous shocks such as the foreign exchange rate shock under the fixed exchange rate regime than under the flexible exchange regime. It also shows that the interest rate rule that responds to financial market conditions is better than any other interest rate rules only if it does not react to the exchange rate fluctuations. Moreover, an interest rate rule that responds to the exchange rate fluctuations, i.e. the monetary policy under the managed floating exchange rate regime is inferior to the monetary policy rules that do not respond to the exchange rate fluctuations. Finally, it shows that the monetary authority needs to stabilize a narrow price index such as domestic price index rather than a general price index such as consumer price index under the financial friction circumstances.
具有金融摩擦的小型开放经济中的货币政策规则选择——以韩国为例
本文首先展示了VAR的实证结果,即韩国经济经历了严重的外生国家蔓延冲击的经济收缩。为了分析替代货币政策对经济的影响,本文按照Bernanke et al.(1999)的思路,建立了一个考虑企业和金融中介机构之间信息不对称导致的金融摩擦的多部门小型开放经济新凯恩斯模型(以下简称NK)。结果表明,存在金融摩擦的小型经济体在固定汇率制度下比在浮动汇率制度下更容易受到汇率冲击等外生冲击的影响。它还表明,只有在对汇率波动不作出反应的情况下,对金融市场情况作出反应的利率规则才比任何其他利率规则更好。此外,对汇率波动作出反应的利率规则,即有管理的浮动汇率制度下的货币政策,不如不对汇率波动作出反应的货币政策规则。最后表明,在金融摩擦环境下,货币当局需要稳定的是国内物价指数等狭义物价指数,而不是消费者物价指数等广义物价指数。
