With CB data in South Korea, this study examines whether the credit risk of borrowers changes when the regulation on bank mortgage supply is relaxed. We analyze the effect of deregulation on LTV and DTI limits in the Seoul-metropolitan area in August 2014 with a difference-in-difference approach. We find that the probability of delinquency is lower in the Seoul metropolitan area after the deregulation than in other urban areas. The effect is noticeable among low-income and low-credit borrowers. We also find that borrowers change their debt structure to reduce the interest costs utilizing their improved access to bank mortgages. The findings suggest the necessity to consider the burden of the high interest costs of unsecured loans for debtors with low incomes and low credit ratings in designing housing finance regulations.

This paper intends to examine the extent of the fiscal contribution of immigrants to Korea. According to this analysis, the aim is to derive implications pertaining to the direction of Korea's immigration policy as a response to fiscal problems caused by population aging. For this purpose, a macroeconomic model is designed to measure the lifetime net fiscal contribution of immigrants in Korea by visa type, age, and other characteristics. According to this analysis, the sum of the lifetime fiscal contribution for all immigrants in Korea is negative. This implies that immigration policy reforms that increase the inflow size while maintaining the current structure of the foreign population characteristics can rather worsen Korea's fiscal problems. This finding suggests that immigration policy reform may exacerbate Korea's fiscal soundness if it simply targets the maintenance of the numerical balance of the demographic structure.

This current study aims to investigate the reason for the low birth rate and increasing aging populations. It aims to offer potential countermeasures and possible solutions that might alleviate the decreasing birth rate and exponentially increasing aging populations. The present research has sought out to uncover the origin of the low birth rates and increasing aging populations by compiling various past studies and statistics in South Korea. It includes additional support from the government for working career women in easing their burden for raising a child and allocating the appropriate funds for the increasing elderly populations. The decreasing birth rate can be contributed as a side effect of the past policies passed in South Korea and in turn created an increase in the aging populations. Policies to tackle this current issue needs to be further investigated and employed for the future of the economic and sociological stability of the society. Consistent efforts need to be made to dispel the continuing decrease for birth rates and alarmingly increasing aging populations. Policies and redistribution of government funds are some of the many things that need to be revised.

Bronchiectasis, which is characterized by irreversibly damaged and dilated bronchi, causes significant symptoms, poor quality of life, and increased economic burden and mortality rates. Despite its increasing prevalence and clinical significance, bronchiectasis was previously regarded as an orphan disease, and ideal treatment of this disease has been poorly understood. The European Respiratory Society and British Thoracic Society have recently published guidelines to assist physicians in the clinical field. Guidelines and reports suggest comprehensive management that includes both non-pharmacological and pharmacological treatment. Physiotherapy and pulmonary rehabilitation are two of the most important non-pharmacologic therapies in bronchiectasis patients; long-term inhaled antibiotics and macrolide therapy have gained significant evidence in reducing exacerbation risk in frequent exacerbators. In this review, we summarize recent updates on bronchiectasis treatment to prevent exacerbation and manage clinical deterioration.

Advanced and innovative breeding and management of meat-producing animals are needed to address the global food security and sustainability challenges. Beef production is an important industry for securing animal protein resources in the world and meat quality significantly contributes to the economic values and human needs. Improvement of cattle feed efficiency has become an urgent task as it can lower the environmental burden of methane gas emissions and the reduce the consumption of human edible cereal grains. Cattle depend on their symbiotic microbiome and its activity in the rumen and gut to maintain growth and health. Recent developments in high-throughput omics analysis (metagenome, metatranscriptome, metabolome, metaproteome and so on) have made it possible to comprehensively analyze microbiome, hosts and their interactions and to define their roles in affecting cattle biology. In this review, we focus on the relationships among gut microbiome and beef meat quality, feed efficiency, methane emission as well as host genetics in beef cattle, aiming to determine the current knowledge gaps for the development of the strategies to improve the sustainability of beef production.

Objective : To estimate the annual economic costs attributable to cigarette smoking in Korea. Methods : The costs were classified as being direct medical and non-medical costs, indirect costs and others. We focused on those costs related that are incurred in the treatment of selected diseases (cardiovascular diseases, respiratory diseases, and cancers), which have been proven to be caused by smoking. In addition to the basic costs of treatment, the additional amount of costs occurred due to smoking was obtained by computing the population attributable risk (PAR%) caused by smoking. To compute the PAR%, relative risks of smoking to the number of outpatient visits, hospitalizations, and the death were estimated using the Cox proportional hazard model, respectively. Our major data source was the 'Korea Medical Insurance Corporation (KMIC) cohort study,' which was composed of a total of 115,682 male and 67,932 female beneficiaries who had complete records of their smoking histories in the year of 1992. Results : The annual costs that could be attributable to smoking were estimated to be in the range of 2,847,500 million Won to 3,959,100 million Won. The maximum estimate of 3,959,100 million Won includes 233,100 million Won for medical costs, 5,100 million Won for transportation costs, 27,600 million Won for care giver's economic costs, 69,100 million Won in productivity loss, 3,435,000 million Won lost because of premature death, 172,100 million Won in costs resulting from passive smoke inhalation and 17,100 million Won for costs that resulted from fires that were caused by careless smoking. Conclusion : Our study confirms that the magnitude of the economic burden of smoking to Korean society is substantial. Therefore, this study provides strong evidence that there is a strong need for a national policy of tobacco control in Korea.

이 연구는 국가별로 납세자들의 납세순응수준을 결정하는 요인들에 대한 분석을 통하여 납세순응수준을 높이기 위한 대안을 모색하는 것이며 이를 위하여 납세자의 조세윤리(tax morale)의 결정요인으로 경제적인 요소뿐만 아니라 Hofstede (1980)의 문화적인 요소가 조세순응(tax compliance)의 현상을 설명하는지 국제적으로 다르게 나타나는가를 실증분석을 통하여 조세순응의 결정요인을 확인하는데 그 목적이 있다 이를 위하여 38개국 5년간 총 190개의 관측치를 이용하여 검증하였으며 검증결과를 요약하면 다음과 같다. 효율적 경쟁법(effective competition law)의 수준이 높을수록, 경제적 자유수준이 높을수록, 정부정책의 투명성이 높을수록 조세순응수준이 높은 것으로 검증되었다. 반면에 지하경제규모가 클수록, 권력거리의 성향이 클수록 조세순응수준이 낮은 것으로 나타났다. 이와 같은 결과는 납세자는 왜 세무당국자에게 조세와 관련하여 저항하고 또한 조세순응(tax compliance)의 상황이 왜 나라마다 차이가 나는가에 대한 원인을 규명하여 납세순응도를 높이기 위한 정책대안이 될 수 있음을 보여주고 있다.

본 논문은 정치경제학적 관점에서 선거 시기마다 재정변수의 주기적인 변화가 있었는지를 실증적으로 검증하고 있다. 재정총량변수를 이용하는 경우 총수입이 선거 이듬해에 주기적으로 감소하였다. 하지만 총지출, 재정수지, 조세부담률 및 국민부담률 등의 재정총량변수를 이용한 경우에는 선거에 따른 재정변수의 주기적인 변화를 발견할 수 없었다. 부문별 지출에서는 경제부문의 지출이 선거 이듬해에 주기적으로 증가하였다. 또한 경제부문 소관위원회의 여당의원 비율이 높을수록 경제부문의 지출 증가율이 높게 나타난 가운데, 선거 이듬해에는 이와 더불어 추가적으로 더 증가한 것으로 나타났다. 이러한 결과는 부문별로 의무 및 재량 지출을 구분하여 분석한 경우에도 동일하게 발견되었다. 따라서 우리나라에서도 정치적 지대 추구행위가 존재해 왔던 것으로 판단된다.
