For this purpose, a Smooth Transition VAR model is employed to document the state-dependent dynamics of two distinct types of uncertainty shocks, namely, financial market based and news-based. When nonlinearity is allowed to play a role in our model, quantitatively very different asymmetric dynamics are observed. Following in inflation targeting, the responses tend to be smoother and less pronounced. Our empirical results support the view that the link between uncertainty and macroeconomic activity is clear over both recessions and expansions. Furthermore, the impact of uncertainty shocks is more pronounced when economic activity is depressed especially after shocks originate from the financial market, and not from news-based policy uncertainty in Korea.","PeriodicalId":208756,"journal":{"name":"BOK ERI: Working Paper Series (Topic)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126618707","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

IMF의 CVU(Corporate Vulnerability Utility)에서 관찰하고 있는 지표를 중심으로 주성분 분석과 동태요인분석을 2회 중복 사용하는 방법을 이용하여 한계기업, 만성적 한계기업을 대상으로 기업 취약성 지수를 산정하였다. 그 결과 만성적 한계기업을 대상으로 한 취약성 지수가 어음 부도율 등 기업부실을 나타내주는 지표와 잘 부합하였으며 최근 들어 취약성 지수가 상승세에 있는 것으로 나타났다.패널 로짓(panel logit) 모형을 통해 만성적 한계기업의 취약성 지수가 정상기업의 부실기업화에 미치는 영향을 추정해 본 결과 취약성 지수가 한 단위 상승할 경우 정상기업에서 한계기업 및 부실위험 기업이 될 확률이 유의하게 상승하는 것으로 나타났다.이러한 분석결과는 구조조정을 통해 신속하고 꾸준하게 만성적 한계기업을 정리할 필요가 있으며 본고의 기업 취약성 지수와 같은 기업부실 위험 징후를 판단할 수 있는 종합적인 지표를 개발하여 이를 금융안정을 평가하는 보조지표로 활용할 필요가 있음을 시사한다.English Abstract : It has been usually taken into account that higher debts of a company tend to increase the risk of insolvency. In the case of Korea, the debt to equity ratio seems to have been stable after the Asian financial crisis thanks to the regulatory effort of reducing companies’ debt to equity ratio below 200%. By the way, unlike the debt to equity ratio, corporate default theories implicate that many Korean companies are highly likely to face default conditions, and the number of companies undergoing restructuring is growing much fast lately.Based on such motivation, this paper develops a new corporate vulnerability index including several debt-related ratios and helping to capture corporate risks, and analyzes the effect of the vulnerability index on corporate insolvency. The index is calculated for the whole, marginal, chronic marginal, and default-risk companies by applying both principal component analysis and dynamic factor analysis with indicators from IMF’s CVU(Corporate Vulnerability Utility). The result shows that the vulnerability index for chronic marginal companies corresponds to the bankruptcy rate on promissory notes which represents the level of corporate insolvency, and recently the index is in a rising trend.According to the estimation of the effect of chronic marginal companies’ vulnerability index on corporate insolvency of regular companies through the panel logit model, the probability of turing into marginal or default-risk companies from regular companies increases as the vulnerability index increases.The implications of the results are as follows. First, swift and steady restructuring needs to be executed for stable real economy. Next, the development of comprehensive indicators by which to detect risk signs, like the corporate vulnerability index in this paper, is required to use them as sub-indicators to assess financial stability.","PeriodicalId":208756,"journal":{"name":"BOK ERI: Working Paper Series (Topic)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134601673","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Suppose that once a borrower fails to pay back a loan to a bank, he cannot borrow from any banks again and must contact higher-interest charging credit finance companies to get a new loan. This creates a well-defined incentive for borrowers: pay back and remain in the banks' loan market vs. do not pay back and move to, say, credit finance companies' loan market in which a higher loan rate is charged. This mechanism does not require the financial firms to verify even if the borrower declares bankruptcy, and therefore is more efficient than a standard debt contract A la Townsend (1979) in terms of verification cost. As the interest rates offered by different types of financial firms should be well aligned in order to prevent the deception of borrowers, we can also analyze how many different types of financial firms, that is, how many discrete and different loan rates, can co-exist in the economy.","PeriodicalId":208756,"journal":{"name":"BOK ERI: Working Paper Series (Topic)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127614037","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When the payment service providers make their revenue from consumer fee, it is shown that the anti-fraud investment is made more by parties with liability, and the anti-fraud investment is socially sub-optimal. When the FinTech payment service provider (FPP) makes its revenue other than from consumer fee, the FPP liability regime leads to greater anti-fraud investment and lower accident probability, compared to the case in raising revenue from consumer fees. The effect under the IPP liability regime, however, is inconclusive.

English Abstract: We investigate the effects of macro-prudential policies on house prices using event study approaches and dynamic panel models. We construct a unique dataset with house price index based on real transactions and newly estimated loan-to-value (LTV) and debt-to-income (DTI) limits for a monthly panel of 98 districts across Seoul, the Gyeonggi Province and six metropolitan cities covering the period from March 2006 to June 2015. We show that DTI limits appear to be more effective in stabilizing house prices than LTV limits. Both tightening and loosening DTI and only loosening LTV limits are effective. Overall, the results indicate that macro-prudential policies could be a useful tool in curbing excessive household debts and the subsequent house price bubbles. This is the first study to estimate LTV and DTI limits at the district level and analyze the effects of macro-prudential policies on house prices. Our study would provide important lessons for the policy authorities that are implementing LTV and DTI regulations with an aim to cope with a surge in house prices and credit extension.","PeriodicalId":208756,"journal":{"name":"BOK ERI: Working Paper Series (Topic)","volume":"13 24","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120853139","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We find that the UMP significantly affected capital flows on average. The effects of the normalization are closely related with the effects of the UMP. Importantly, the larger the capital inflows due to the UMP, the larger the capital outflows due to the normalization. Moreover, policy makers need to be careful of a potential risk of unexpected capital outflows (exceeding the expected ones) during an uncertain period whose size tends to be proportional to the size of the previous capital inflows.","PeriodicalId":208756,"journal":{"name":"BOK ERI: Working Paper Series (Topic)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130438118","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results of empirical analyses based on the estimated model can be summarized as follows. First, the sectoral reallocation of labor plays an important role in the adjustment of the Korean labor market, which responds to macroeconomic shocks, particularly foreign shocks. Second, the historical decomposition analysis demonstrates that the cyclical fluctuations of unemployment in Korea are explained by key domestic shocks, such as domestic productivity shocks and preference shocks.
