Recently, we have witnessed that insolvency of some savings banks caused considerable confusion in the populace financial market. In this context, this study analyzed empirically about the credit quality of the savings banks verifying the hypothesis - ‘The rise of loan interest rate will worsen the credit quality of the savings banks occurring so-called adverse selection’. In case of using overall data, the result shows that the rise of loan interest rate in savings banks worsened credit quality. This finding could be interpreted that the rise in interest rates caused possibly the release of superior customer while increase of poor customer by the adverse selection. However, in case of savings banks in Busan district (excluding insolvent savings banks), it is turned out to improve the credit quality of savings banks after the rise of loan interest rate differently from previous result. This means that most of the savings banks located in Busan area (excluding troubled ones) seems to do good risk management relatively. Theses results imply that the reasons of recent contraction in activity of microfinance institutions could be attributed to some troubled savings banks. 최근 발생한 일부 저축은행들의 엄청난 부실이 서민금융시장에서 적지 않은 시장 혼동 상황을 불러일으켰다. 이러한 맥락에서 본 연구는 서민금융기관 중 저축은행들의 여신 건전성에 대해 실증 분석하였다. 국내 저축은행 전체와 부산지역 저축은행들을 나누어 패널분석을 통해 ‘여신금리의 상승은 역선택으로 인해 여신건전성을 악화시킨다’는 가설을 검증하였다. 전체를 대상으로 분석한 결과의 경우, 저축은행의 여신이자율이 상승하면 여신건전성이 일부 악화되는 것으로 나타났다. 이러한 결과는 이자율의 상승이 역선택에 의해 우량신용고객의 이탈을 초래하고 여신 건전성이 훼손되었기 때문이라 판단된다. 또한 동일한 분석을 부산지역 저축은행들(부실금융기관은 제외)에게 적용한 결과, 대출이자율의 상승이 여신건전성 악화를 초래하지 않고 오히려 개선시키는 것으로 나타났다. 즉 부산지역 저축은행들의 경우 일부 부실 저축은행들을 제외하면 대부분 여신관리를 비교적 잘 수행했던 것으로 해석된다. 즉, 여신이자율의 상승이 역선택을 초래하지 않았을 정도로 위험관리능력과 신용평가능력을 어느 정도 갖춘 것으로 사료된다. 결론적으로 부산지역에서 최근 저축은행들의 여·수신 활동이 크게 위축된 이유를 찾는다면 일부 부실 저축은행들이 그 원인을 제공한 것으로 풀이된다.
The Effects of Monetary Policy Shocks in Japan
배근호 한국자료분석학회 2007 Journal of the Korean Data Analysis Society Vol.9 No.6
This study examined the role of interbank market rates in the conduct of Japanese monetary policy and the effects of monetary policy shocks in Japan. This issue is whether monetary policy innovations in Japan are better represented by shocks in an interest rate or in money. A typical result for Japanese data is that the Bank of Japan uses the interbank market rate as its operating target rather than total reserves. I found that the call money rate(CMR) innovations are a better indicator of policy stance than the money innovations (M2+CDs) in Japan. This stated that the interbank interest rate continues to be the primary operating instrument of the Bank of Japan despite primary major institutional changes in Japanese financial markets over the past decade.

This paper has examined the suggestions of Korean banks by analyzing the cases of bank industry of the countries who have faced similar financial crisis in the 1990's. The outcome of this study was that there is a common feature of nations whose bank profit and prices of stock increased. That is quick increment of corporate loans along with withdrawal of credit crunch after successfully completing the bank restructuring. Korea is similar in that there were some kind of restructuring of bank organs and decrease in insolvent bonds. However As foreign countries' case shows, loans, especially those of an enterprise, should be enlarged in order to keep increasing bank profit and stock prices. Since the currency crisis, Korea has achieved considerable success in financial restructuring, but it is desirable for the banks to expand sound loan for corporate in order to improve the competitiveness and profitability of the financial sector. At the same time, efforts must be made to strengthen market discipline and to enhance the transparency of financial information. Standard for accounting and public disclosure should be heightened to enable shareholders, creditors, and others to gauge financial institutions' management performance accurately from their financial statements. On the other hand, to promote the improvement of corporate financial structures and the prompt resolution of ailing companies, more accurate valuation of corporate credit risk and the restructuring of financially troubled companies under the leadership of financial institution, should become firmly established at the earliest date possible.

The objetives of this paper is to seek the effects of the moving of public financial instition on Busan using export-based model. This paper is discriminated in that existed research is generally analyzed using input-output analysis. The results show that the acceleration of 6,200 new employment and the increase of regional output of 310 billion won, the increase of value added of 170 billion won are shown after the moving of public financial institutions to Busan. With this, It is expected that the increase of employment of high quality human resources and regional tax revenue and vitality of regional economy will additionally happen. However, this empirical analysis need to do more study in that the results found in this paper are partial and include lots of variables according to the change of economic situation. 본 논문은 금융 공공기관의 이전이 부산지역 경제에 미치는 효과가 어느 정도인지를 알아보기 위해 수출기반모형을 사용하여 분석하였다. 기존 연구가 주로 투입-산출모형을 사용하여 파급효과를 분석한 데 반해 본 연구는 다른 분석 방법을 사용함으로써 기존 연구결과와 차별화된다. 여기에서 분석된 경제효과는 금융 공공기관의 부산지역 이전이 완료되었을 경우 나타나는 효과이다. 분석 결과, 4개 이전대상 금융 공기업이 부산지역으로 이전할 경우 이전에 따른 지역경제 규모의 증가 효과는 6천2백여명의 고용증가와 약 3천1백억원의 생산액 증가, 1천7백여억원의 부가가치 증가 효과가 나타나는 것으로 분석됐다. 이밖에도 고급인력의 고용기회 증대, 지방세수의 증가와 지역경제 활성화 등 부가적인 효과가 나타날 것으로 예상된다.
중소기업의 생존율 실증분석 : 보증지원이후 생존조사를 중심으로
배근호,박광수 한국자료분석학회 2012 Journal of the Korean Data Analysis Society Vol.14 No.2
본 연구는 기술신용보증기금이 보증하는 중소기업들을 지역, 영위업종, 기업인증유형, 업력, 보증금액 등으로 분류하여 보증이후 생존분석을 시도하였다. 이를 위해 카플란-마이어(Kaplan- Meier) 분석 기법을 사용하여 생존시간을 추정하였으며, 그 결과가 통계적으로 유의한지를 실증 분석하였다. 특히 기존 연구 중 홍성로․남기정․정낙원(2006)이 분석한 결과와 비교 설명하고자 하였다. 그 결과 첫째, 기업이 속한 지역별로 생존율과 생존시간을 추정한 결과 통계적으로 유의하지 않은 것으로 분석되었다. 둘째, 기업이 속한 영위업종별로 생존시간을 추정한 결과도 통계적으로 유의성이 높지 않았으나, 기업의 인증유형에 따라 분류한 후 분석한 결과에서는 통계적으로 매우 유의한 것으로 나타났다. 셋째, 기업의 업력과 산업재산권의 보유건수, 보증금액에 따라 기업을 분류한 결과 생존시간의 차이가 통계적으로 유의하였으나, 종업원의 수와 자금용도에 따라 분류한 결과는 유의하지 않은 것으로 분석되었다. This study has analyzed the survival probability and time of small and medium companies guaranteed by KIBO categorizing in terms of business areas, business industries and types, patents and so on. To estimate the survival probability and time, we have used Kaplan-Meier Analysis and checked the statistical significance level. Especially, we have investigated the findings of the existing paper of Hong-sungro, Nam, Jeong (2006). The results are as follows. First, the survival probability and time in terms of business area is not statistically significant. Secondly, the survival probability and time by classifying business industries are not highly statistically significant but, the result by certification type is very statistically significant. Third, the age and the number of patent of estimated companies and guaranteed money have affected the survival time. However, the survival time by classifying in terms of the employee and the character of used funds is not statistically significant.

This research has investigated important but still arguable hypotheses regarding the international transmission of economic disturbances. After the move to a floating exchange regime, it was commonly believed that the greater flexibility of exchange rates under a floating regime would insulate domestic economy from the influence of foreign shocks. Empirical results show the interdependencies between the U.S. and Japanese economies. And, these results provide evidence that flexible exchange rate regime has not in general insulated Japanese economies from foreign influence, since general results obtained here show that Japanese economy was still influenced by the U.S. innovations over the flexible rate period.
시스템 다이내믹스를 활용한 부산지역 금융산업의 경쟁력 분석
배근호 한국자료분석학회 2009 Journal of the Korean Data Analysis Society Vol.11 No.4
The objective of this paper is to analyze the effective changes of activating the financial cluster in Busan. The analysis is simulated using System-Dynamics method on the basis of the advanced financial market case study. The results show that the attractiveness of international financial center increase greatly with the rise of the financial insurance inex which is affected by the sharp rise of financial institutions and companies. The activity of financial industry induces the developing of a variety of business model. And, the increase of the exchange of inter-industry and trading leads to strengthen the competitiveness of Busan area through the expansion of regional GDP in Busan. However, these results could be quite flexible according to the different hypothesis in controlled variables used in analysis. Neverthless, the point that we can't acquire competitiveness without innovative policy change would be leaved as policy implications in this paper. 본 연구는 국제금융센터의 건립을 전제로 부산지역에서 금융산업 클러스터가 활성화되었을 때에 미치는 파급효과를 분석한 것이다. 시스템 다이내믹스의 방법론을 활용하여 해외 선진사례의 가정을 토대로 시뮬레이션하였다. 분석결과 해외 선진금융 및 기업들을 유치할 수 있는 국제금융센터의 매력도는 금융보험업 지수의 상승과 함께 크게 증가하는 것으로 나타났다. 또한 금융산업 클러스터가 활성화되면 사업서비스 산업을 바탕으로 각종 비즈니스 사업을 발전시킬 수 있으며, 산업간 교류와 교역량의 증대는 결국 부산지역의 GDP의 확대를 통해 부산의 경쟁력을 강화시킬 수 있을 것으로 분석되었다. 하지만 본 연구에서 가정한 몇 가지 변수들의 경우 국가의 정책적 차원에서 결정되어야 할 문제인 만큼 보다 유연한 해석이 필요하다. 또한 본 연구의 시뮬레이션에서 사용된 모형의 변수들은 해외 사례를 통해 가정하여 나온 결과인 만큼 유연한 해석이 요구된다. 그러나 이 모형에서 사용된 주요 변수들과 같이 파격적인 변화를 수반하지 않고서는 금융클러스터의 활성화 및 국제 경쟁력의 확보는 어려울 것으로 판단된다는 점에서 본 연구의 정책적 시사점으로 얻고자 한다.
The Empirical Analysis on the Examination of Mundell-Fleming Hypothesis
배근호 한국자료분석학회 2006 Journal of the Korean Data Analysis Society Vol.8 No.6
Mundell-Fleming model of an open economy assumes that the conditions of perfect capital mobility and static exchange rate. The implications of these conditions is that monetary policy influences aggregate demand entirely through effect on the exchange rate rather than interest rates. In this paper, I investigated a hypothesis due to Mundell(1968) using VAR methodology in case of various countries. The Mundell-Fleming model leads to strong conclusions about the international transmission of monetary policy which has negative spillover effects on foreign output. However, it is evident from the results obtained in this paper that the transmission of monetary policy shocks across open economies can not routinely be generalized to countries. Overall, the evidence presented in this research is not supportive of Mundell hypothesis across countries. The implication is that the actions of domestic economic policy authorities can not be treated as unresponsive to the environments which they face, but must be modeled together with the rest of the economy.
