This paper analyzes the redemption risk of renters by estimating the LTV and CoLTV with finance market big data (individual credit information) and housing market big data (actual housing transaction data). The analysis showed that when using LTV, the redemption risk was higher in the case of the monthly renter than of the chonsei renter. On the other hand, when using CoLTV, the chonsei renter had a higher redemption risk than the monthly renter. This implies that there is a need to activate a guarantee system, such as risk management using the CoLTV index and the chonsei deposit return guarantee because it is possible for renters to experience losses on their chonsei deposits due to the higher redemption risk. Another implication is that the risk manager should consider the individual characteristics of renters because of the different effects of the redemption risk stemming from the characteristics of the rental contract and the personal characteristics of the renters. CoLTV was just a concept until this study calculated it using housing big data and actual housing transaction information. It helps identify the redemption risk through the characteristics of renters and their contracts.

The medical institution considers liability management problems as a direct factor in managerial risks, such as bankruptcy. Cash Flow provides useful information to necessary funds and predicting bankruptcy. The study for 24 general hospitals and 23 hospitals, a regression analysis was performed to determine the impact of cash flows on the debt repayment capability, a multivariate discrimination analysis was conducted to find out how to manage cash flow for the risk posed by debt. The analysis results, For general hospitals, the level of debt repayment capability was done to net income, increase of payables from operating activities and decrease of patient receivables and inventories from operating activities. If there is no dept repayment capability, it is necessary to increase the net income, increase the expenses not involving cash outflows, decrease of patient receivables and increase of payables from operating activities. For hospitals, the level of debt repayment capability was done to net income, increase of expenses not involving cash outflows and payables from operating activities, decrease of income not involving cash inflows, decrease of patient receivables and inventories from operating activities. If there is no dept repayment capability, it is necessary to increase of payables from operating activities.

As there is a growing concern about the steady increase in the consumer debt and its potential consequences on individuals and families, this study examined the association between personal debt and the risk of domestic violence, which in this study is referred to as violence between man and woman who have a spousal relationship. We used the data from the Korea Welfare Panel Study collected from 2009 to 2016. We applied a generalized estimating equation approach for the analysis of panel data. The results show that the higher the ratio of personal debt to disposable income and the ratio of debt payment to disposal income is, the greater the risk of domestic violence. While the debt to income ratio played a role regarding was related to a heightened risk of domestic violence among the poor group, the debt payment to income ratio was associated with a higher risk of domestic violence among the non-poor group. Implications of the study were discussed.

Lately, rapid increase of household debt and economic change has affected cash flow of household, insolvent risk has increased by high repayment burden of the principal and interest. Previous researches was progressing various discussion, composed objective repayment burden index about household debt. But it was relatively insufficient about perception of consumer. This research compare and analysis determinants of subjective repayment burden in household debt by income quintile, using 2016 Household Financial Welfare Survey. The research result is follows. The income 1 and 2 quartile groups have the higher monthly rent and credit card loan and the housing preparation loan ratio, the higher burden on repayment of the principal and interest. The Income 3 and 4 quartile groups have the higher 60s or older and member of household and real estate mortgage loan, the higher burden on repayment of the principal and interest. The Income 5 quartile group has the higher loan ratio for debt repayment preparation, the higher burden on repayment of the principal and interest.

This paper characterizes an optimal combination of grant and income-contingent loans (ICL) from efficiency and equity points of view as a government subsidy program for higher-education. In particular, we show that it is always desirable to introduce ICL for students regardless of their household incomes, and also provide arguments for the superiority of tax-financing system to loans with risk-premium as a financing mechanism of ICL. From policy point of view, this paper suggests a need for the extended coverage of our ICL system, while justifying its current tax-financing system.

Mortgage-Backed Securities (MBS) was introduced in 1999 in order to stabilize housing market and prevent potential speculation. However, research on MBS is limited, so this paper try to narrow the gap by focusing on the factors relating the pre-payment risk of MBS. We used Granger Causality Validation, Vector Auto Regressive, and HP-filtering with time-series data from 2004 to 2014. This paper shows that the prepayment rate of MBS increases as Mortgage rate decreases because borrowers tend to refinance existing MBS with new lower-rate MBS. In addition, it reveals that the rate increases as housing price increases. This outcome support the hypothesis that introduction of low-rate MBS invites more investment or speculation, and hence the housing price rises. The relationship between the MBS pre-payment rate and housing price is yet a peculiar characteristic of the MBS in Korea.

We conduct a comprehensive risk analysis of household debt in Korea for the first time using the whole sample credit bureau (CB) data of 2.2 million individual debtors. After analysing debt service capacity profiles of debtor groups classified by the borrower characteristics such as income, age, occupation, credit scoring, and the type of creditor business companies, we investigate the impact of interest rate and income changes on debt service-to-income ratios (DTIs) and default rates of respective debtor groups. Empirical results indicate that debt service burdens are relatively high for low income wage earners, high income self-employed, low income capital and card loan holders, and high income mutual savings loan holders. We also find that debtors from multiple financial companies are particularly weak in their debt service capacity. The scenario analysis indicates that financial companies, with the current level of capital buffers, may be able to absorb negative consequences arising from the increase in DTIs and loan default rates if the interest rate and income changes remain modest. However, the negative consequences may fall disproportionately on non-bank financial companies such as capital, credit card, and mutual savings banks, whose debtors' DTIs are already high. We also find that the refinancing risk of household debt is relatively high in Korea as more than half of household mortgage debts are bullet loans. As the DTIs of mortgage loan holders are already high, under the current DTI regulation, mortgage loans may not be readily refinanced especially when the interest rate rises. Disruptions in mortgage loan refinancing may put downward pressure on housing prices, which may in turn magnify refinancing risk under the current loan-to-value (LTV) regulation. Overall our analysis suggests that, for more effective monitoring of household debt risk, it is necessary to combine existing surveillance schemes based on macro aggregate indicators with more comprehensive and detailed risk analyses based on micro individual data.

I examine the relationship between values and security designs of MBS(mortgage-backed securities), using four different types of them. To this end I consider a pass-through and three different kinds of CMOs(collateralized mortgage obligations). It turns out that the pass-through has the lowest value and that, among CMOs, that of a senior-mezzanine-subordinate design has the highest value. This implies that CMOs of a simple and extreme design, like that of a senior-subordinate design, are not likely to be the best CMOs for risk averse buyers. Another critical finding is that the optimal security design of CMOs or MBS does exist in the form of an interior solution. This indicates that MBS issuers could charge higher prices of MBS given their underlying mortgages by tailoring MBS security designs to the needs or utilities of MBS buyers, usually by removing and combining risks of component tranches of MBS. Accordingly a thorough study of realistic utility functions of MBA buyers could enhance the values or prices of MBS to be issued.

Forfaiting is a trade finance facility whereby financial institution purchases accounts receivable from exporters on a without recourse basis to resolve exporters' credit risk. Since the effectuation of Uniform Rules for Forfaiting(URF 800), exporting companies have been interested in forfaiting and foreign exchange banks in South Korea have expanded products related to forfaiting. However, the risk management for dealing with forfaiting needs improvement. In this paper, we will compare current forfaiting risk managements between foreign exchange banks and foreign banks in South Korea by studying the agreements for each bank and standard forfaiting agreements of the ICC. There is a significant gap for risks covered and points of reserve(points of recourse) between each bank. This work suggests the need for unification for these gaps in order to enhance risk management for exporting companies and foreign exchange banks in South Korea.
