Households have experienced economic instability since Korea economic crisis in 1997. This study attempts to explore the financial management behavior by the types of economic instability classified considering the two aspects of the employment and the income instability of the households. The specific objectives of this study are : 1) to classify households’economic instability in terms of employment and income instability. 2) to examine whether the financial management behavior is different between households experiencing the different types of the economic instability. The sample consisted of 792 married women living in Seoul. The statistical methods used for analysis included Reliability, Frequencies, Percent, Mean, Standard Deviation, Analysis of Covariance, one-way Anova, DMR-test. The major results can be summarized as following : 1) The economic instability experienced by houeholds can be classified into the 4 types employment-income instability, employment instability income stability, employment stability$.$income instability, and employment$.$income stability. 2) There are statistically significant differences in the levels of financial management behavior between households having the different types of economoc instability. The results of this study could be needed for development of the employment policies and the financial education programs.

This paper empirically examines how fiscal instability affects financial instability. According to an IMF forecast (2021a), the fiscal space in Korea will be steadily reduced in the future. The theoretical literature predicts that if fiscal stability is undermined, financial stability will also be in danger given that government guarantees on banks are weakened and/or sovereign bonds held in banks become riskier. This paper empirically finds the existence of this negative impact of fiscal instability on financial instability. I also find that the intensity of this fiscal-financial relationship is greater in a country where (i) its currency is not a reserve currency such as the US dollar or euro, (ii) its banking sector is large relative to government sector, and/or (iii) its private credit to GDP is high. Korea has all of these three characteristics and hence needs to put more effort into maintaining fiscal stability.

Theoretical literature agrees on the interaction between financial instability and economic activity but explains it's dynamic in two points of view: one is that the transmission mechanism occurs in one unique regime and the other reckons a shift of regime leads to the alteration of the transmission mechanism. This study aims to find evidence of the multi-regime transmission for ASEAN developing countries. The author employs the technique of Threshold vector auto regression using the financial stress index standing for financial instability. Monthly data is collected, covering a period long enough with many episodes of high stress in recent decades. There are two conclusions: (1) A financial shock has a negative and stronger impact on economic activity during a high-stress period than it does during a low-stress period; (2) the response of economic activity to a negative financial shock during high-stress periods is stronger than it is during normal times. The findings point to the importance of the financial stress index as an additional early warning indicator for the real economy sector, as well as the positive effect that a reduction in financial stress may have on economic activity, implying the importance of "unconventional" monetary policy in times of high financial stress.

The purpose of this study was to investigate influences on wives' financial management behavior economic instability and coping behavior of urban household. Economic instability was constructed with an objective economic status and perceived economic instability. And, Financial management behaviors were constructed with four dimensions : investment, income/expenditure, risk, and debt management behavior. The subjects of this study were 225 housewives. Factor analysis, Cronbach ${\alpha}$, and multiple regression were performed for data analysis. The results show that, coping behaviors of searching and using information and perceived economic hardship related to debt influenced housewives' investment management behaviors. The coping behaviors of searching and using information, expending in the range of planned budget, using debt, perceived economic hardship related to debt, income insufficiency, and selective expenditure influenced the consumption-expenditure management behaviors. Perceived economic hardship related to essential expenditures and coping behaviors of searching and using information influenced the risk management behaviors.

In Korea, the institutional reform for the national medical insurance system is in process. Eventually, three kinds of the national medical insurance system, i.e., medical insurance program for the industrial workers, the govemment employees and the private school teachers, and the self-employeds, would be merged into an unifed system. In this study, I analyzed the annual trends of the finance in the medical insurance system in Korea, in which I found the financial instability especially in the medical insurance program for the self-employeds. The regression analysis was carried out to forecast the accumulated reserve at the end of this year for the medical insurance program for the self-employeds. I also analyzed the economic effect of the merge of the medical insurance program for the self-employeds by using the case of Japan and Korea. I found that the medical insurance for the self-employeds is expected to have financial deficit at the end of the year 1998 after the merge. In onclusion, it seems to be quite difficult to solve the financial instability in the medical insurance program for the self-employeds after it would be merged. That means that there would be a lot of problems on the way to the merge.

본 연구는 고용불안을 정의하고 실제 자료를 사용하여 이를 측정하여 고용불안에 대한 사실들(facts)을 찾고 그 원인을 분석한다. 고용불안을 실직의 두려움과 재취업의 어려움으로 정의할 때 우리나라에서 고용불안은 외환위기 발생 전에 비해 2000년 이후 상당히 높아졌으며 이는 대부분 일용직 종사자 집단의 고용불안 증대에 기인한다. 이러한 고용불안의 증대는 고용의 소멸이 많아졌기 때문이기도 하지만 창출되는 고용도 일용직 중심으로 이루어지고 있기 때문이다. 뿐만 아니라 외환위기 하에서 대대적으로 실시된 공공근로 정책으로 일용직에 진입한 근로자들의 고용불안 증대가 노동시장 전체의 고용불안 증대와 깊이 관련되어 있다.

오경주와 김태윤 (2007) 등은 위기 관련 데이터의 희귀성 에서 발생하는 문제를 해결하기 위해 과거 금융시장이 안정적이었던 구간을 기준 구간으로 설정하고 기준 구간의 금융시장 움직임을 점 근 자기회귀 모형으로 적합한 후 현재의 금융시장 상황과 비교하여 불안정 지수를 도출할 것을 제안하였다. 그러나 비모수 기법인 신경망을 사용하여 도출된 불안정 지수가 기준 구간의 데이터에 지나치게 의존하는 관계로 불안정 지수가 종종 실제 경제상황을 제대로 반영하지 못하는 것으로 관찰되고 있다. 본 연구에서는 비모수 기법인 신경망과 모수 기법인 선형모형을 이용하여 기준구간에 대한 적합을 독립적으로 수행하여 두 종류의 불안정성 지수들을 도출한 후 이 둘을 결합한 통합 불안정성 지수를 사용할 것을 제안한다. 두 지수의 적절한 통합을 위해 신경망과 선형모형을 통해 도출된 두 지수의 최적 결합비율을 부여하는 방법을 제안하며 제안기법의 타당성을 국내 주식시장 대상으로 검증하였다.

Asset prices decline sharply and stock markets collapse when financial crisis happens. Recently we have encountered more frequent financial crises than ever. 1998 currency crisis and 2008 global financial crisis triggered academic researches on early warning systems that aim to detect the symptom of financial crisis in advance. This study proposes a risk recovery index for detection of good opportunities from financial market instability. We use SVM classifier algorithms to separate recovery period from unstable financial market data. Input variables are KOSPI index and V-KOSPI200 index. Our SVM algorithms show highly accurate forecasting results on testing data as well as training data. Risk recovery index is derived from our SVM-trained outputs. We develop a trading system that utilizes the suggested risk recovery index. The trading result records very high profit, that is, its annual return runs to 121%.

The detrimental impacts of financial instability on the world economy during the financial crisis highlighted the requirement to understand the existing financial circumstances. Stability and developments in financial conditions are important for economic prosperity. This study analyses the impact of geopolitical risk on the economic conditions of some specific emerging economies using monthly data from January 1999 to September 2016 by applying a fixed-effects panel data model. The estimation results demonstrated that geopolitical risk has a significant, negative impact on financial conditions. It shows geopolitical risk could be seen as a key factor that contributes towards financial conditions. Further, it implies that negative shocks of high geopolitical risk experienced by emerging economies are one of the primary reasons for the financial conditions' deterioration. The findings provide important insights for governments, policymakers, and investors. For instance, governments and politicians should refrain from expressing or producing tension, economic discomfort, or news that is likely to increase a high geopolitical risk. Maintaining a close eye on geopolitical risk and its sources may also help to stabilize financial conditions and develop a well-functioning financial system. As a result, investors would be better informed about an economy's economic and financial conditions, allowing them to diversify their international portfolios and devise investing strategies during uncertain economic times.
