This descriptive research study investigated the mediating effect of positive psychological capital (PPC) on the relationship between emotional labor (EL) and job satisfaction (JS) of clinical nurses. The data was collected from 274 nurses working for two hospitals in the D city, Korea, from 7 Sep. 2016 through 23 Sep. 2016. General characteristics, EL, JS, and PPC were surveyed using structured questionnaires. Statistical analysis was performed using descriptive statistics, ANOVA, and stepwise multiple regression analysis with SPSS/WIN 21.0. The mediating effect of PPC on the relationship between EL and JS was tested using Baron & Kenny's 3-step hierarchical regression analysis. There were negative correlations between EL and JS (r=-.36, p<.001) and EL and PPC (r=-.25, p<.001) and a positive correlation between JS and PPC (r=.47, p<.001). In addition, the PPC, had a partial mediating effect (z=-3.44, p=.001) on the relationship between EL and JS. It is proposed, based on the results, to develop an organized intervention program that enhances job satisfaction by reducing emotional labor and strengthening positive psychological capital in clinical nurses.

우리 경제는 외환위기를 계기로 단기금융시장을 포함한 국내 자본시장이 전면 개방된 동시에 외환거래 역시 대폭 자유화됨에 따라 실물부문은 물론 금융부문에 있어서도 완전한 개방경제체제로 전환하였다. 이러한 전면적인 자본시장 개방은 국내외 자본시장의 통합을 촉진하는 동시에 환율, 금리, 물가 등 거시 금융변수간의 상충관계(trade-off)에 변화를 초래함으로써 거시경제정책 환경도 크게 변호시킬 것으로 기대된다. 본고에서는 국내외 금리 및 주가간의 동조화 현상에 초점을 맞추어 자본시장 개방에 따른 국내외 자본시장 통합 효과를 살펴본 후, 자본시장 개방이 환율변동패턴의 통계적 특성에 어떠한 영향을 미쳤는지를 분석하였다. 특히 외환위기를 계기로 국내 자본시장이 제도적으로 완전 개방된 점을 고려하여 위기 이전과 이후에 자본시장 통합도와 환율 변동패턴에 어떠한 변화가 발생하였는지를 실증분석하였다. 금리에 대한 실증분석 결과는 외환위기 이후 금리재정거래(金利裁定去來)(interest parity)가 국내금리변화에 미치는 영향이 크게 확대되고 있음을 나타내고 있다. 주가에 대한 실증분석의 경우에도 미국과 국내주가 간의 동조화 현상이 외환위기 이후 심화되고 있으며, 국내 주식시장이 효율적 시장가설(efficient market hypothesis)을 지지하는 방향으로 변화하고 있음을 나타내고 있다. 환율의 경우에도 외환위기 이후 환율변동패턴에 임의보행(random walk)적 특성이 보다 강화된 것으로 나타나고 있어 외환시장의 효율성이 제고되었음을 시사하고 있다.

This paper explores the effect of the countercyclical capital buffer using a DSGE (Dynamic Stochastic General Equilibrium) model with a banking sector. The main results are following. First, if the CAR (capital asset ratio) rises by 1%p as the countercyclical capital buffer, output and credit would increase less than otherwise by 0.8%p and 1.2%p, respectively. Second, the countercyclical capital buffer would decrease both credit and debt of banks, or deposit, and, as a result, boost the CAR. However, if we are going to use monetary policy to control credit expansion by allowing the interest rate to respond to credit, bank capital would also diminish, which would cause the CAR to be lower.
