This study uses the panel probit model to investigate and evaluate the relationship between exchange rate regimes, political stability, and carbon dioxide during currency crises. To understand currency crisis times, we study a panel dataset of seven South Asian nations that contain annual observations from 1996 to 2020. Furthermore, we created the EMPI exchange market pressure indicator to detect crises. Our results strongly suggested that fixed exchange rate is negatively associated with currency crises, with good regulatory quality and better effective governments. Simultaneously, the floating exchange rate is positively related to the currency crises in those countries where the rule of law has less adequately flowed. However, CO₂, exports, and interest rates are buoyantly associated with crises. The floating exchange rate, the rule of law, exports, and interest rate are associated positively and contribute more prone to the crisis episodes. Negatively associated variables contributed less amid crises episodes: fixed exchange rate regime, government effectiveness, and regulatory quality. Meanwhile, CO₂ has a positive relationship with a currency crisis and contributes more likelihood to the probability of a currency crisis. Countries that adopted the fixed exchange rates with effective governments and regulatory quality faced more minor currency crises.

Purpose: It suggests that in order to compare economic development between large cities, this paper aims to exclude factors such as GDP, trade, manpower, R&D, then present newly an analysis of others (inflation, exports, middle-class, competitiveness, digital). Research design, data, and methodology: In the period of rapid digitalization of the world, we would like to deal with different analysis factors than before. This is because digitalization and prices have the greatest impact on the region in terms of national competitiveness. Random sampling was used as the sample size of this study to generate various values for the annual income of the middle class and the competitiveness index, and the analysis method was used. This is because the income of the middle class can lead the digitalization of the country and accelerate it to standardization. Results: Based on these analysis, it is necessary to reduce the inflation rate of digitalization, it is necessary to lower inflation rates. This can be more fundamental than interest rates. If the demand for digitalization is reduced, national competitiveness, national competitiveness will lower national competitiveness. By building a hub for middle class, you can reduce this inflation rate without China's oversupply. Conclusion: This is because it is difficult to maintain competitiveness through interest rate control, as prices rise, and inflation can become unstable. This study can seek digital acceptance by the middle class as a solution to problems like the regional economic confrontation of new globalization inflation environment.

Purpose: The paper analyzes for detecting unexpected shocks such as global financial crisis and COVID-19 pandemic, and contagion between countries by capturing in the mean-shift, variance-covariance-shift, and skewness-coskewness-shift parameters of interest rates. Research design, data and methodology: A flexible multivariate model of interest rates is provided by allowing for regime switching and a joint skewed normal distribution. The model is applying to the structural breaks of crisis and contagion between the US and the selected global bond markets during the global financial crisis and COVID-19 pandemic, respectively. Inspection of the moment statistics weakly suggests a flight to safety to the US during the global financial crisis and to Canada during the COVID-19 pandemic. Results: The results indicate that risk averse investors had a higher risk appetite for the US and Canada assets during the crisis regimes, compared to their counterparts. Conclusions: The results show that coskewness contagion dominates correlation contagion, and coskewness contagion is significant for the Korea and Japan-US pairs for the global financial crisis and the Euro-US pair for the COVID-19 pandemic. All channels of structural breaks of crisis and contagion are significant when considered jointly, reinforcing the need to consider contagion and structural breaks during crises in a multivariate setting.

ESG는 모든 기업에게 선택이 아닌 필수 사항이 되었으며, 국내 주요 은행들도 ESG 경영을 적극적으로 실천하고 있다. 은행은 ESG 내부활동 뿐만 아니라 자금공급의 중개자로 ESG 금융을 제공하는 역할을 수행하고 있다. 최근에는 디지털 신기술과 결합하여 친환경 활동 수행 시 우대금리를 제공하는 ESG 금융상품을 출시하고 있다. 그러나, 무분별한 우대금리 제공은 은행의 수익성에 악영향을 미칠 수 있으며, 환경인식 개선에 실질적으로 기여하지 못할 경우 그린워싱(Greenwashing) 문제에 직면할 수 있다. 이에 본 연구는 전기 절약과 연동된 ESG 디지털 적금상품을 연구 대상으로 선정하고, 가입자의 실제 데이터를 통하여 소비자의 환경인식과 저축행동을 실증적으로 분석하였다(표본수 2,478개). 본 연구의 주요 결과는 다음과 같다. 첫째, ESG 디지털 적금상품의 가입 현황을 분석한 결과, 30~50대가 주요 고객층으로 나타났으며, MZ세대는 다른 세대에 비해 전기 절약 실천을 통한 우대금리 달성에 있어 상대적으로 높은 성과를 보였다. 둘째, 소비자의 환경인식은 ESG 금융상품의 목표 달성에 유의한 영향을 미치는 것으로 나타났다. ESG 디지털 적금상품은 저축의 기본 기능에 충실함과 동시에 환경인식을 높이는 데 기여할 수 있음이 확인되었다. 셋째, 환경인식은 소비자의 저축 납입행동을 유도하지 못했으며, 이는 지속적인 소비자 관여가 필요함을 시사한다. 본 연구는 환경인식(Environmental Awareness)과 저축행동이론(Theory of Saving Behavior)을 기반으로 ESG 금융상품의 목표 달성에 미치는 소비자 인식 및 행동을 학문적으로 설명하였다. 연구의 결과는 ESG 금융상품의 우대금리 설계의 적정성이 중요함을 시사한다.

본 연구는 다항회귀분석을 통해 장기금리와 단기금리의 차이인 금리 스프레드와 주식 수익률 간 영향을 분석한다. 기존 연구들은 미국시장을 중심으로 금리 스프레드를 통한 경기를 예측에 초점을 맞추어 진행되었다. 선행 연구들은 장단기금리의 기간을 조절하고 선행정도를 분석하며 금리 스프레드를 경기예측 선행지표로 검증했다. 국내에서도 2006년 경기종합지수 제 7차 개편 이후 금리스프레드를 경기 선행지수 구성항목에 포함하였으며 현재까지도 활용하고 있다. 그럼에도 불구하고 국내 주식시장에서 금리스프레드와 산업별 주식 수익률에 대한 연구는 부족하다. 때문에 본 연구에서는 국내주식시장을 대상으로 금리스프레드와 산업별 주식 수익률은 분석했다. 회귀분석을 통해 인과관계가 높은 장단기 금리를 선정하고 선행기간 및 산업별 상관관계를 파악했다. 연구 과정에서 단순 선형회귀 분석(Simple Linear Regression)의 한계를 극복하기 위해 다항 회귀분석(Polynomial Linear Regression)을 활용해 설명력을 높였다. 분석 결과 6개월 선행하여 무보증 3년 회사채(AA-) 수익률과 콜금리 수익률의 차이 금리스프레드로 사용했을 때 높은 인과를 확인하였으며 산업별 주식수익률을 분석한 결과 해당 금리 스프레드와 자동차산업의 수익률의 관계가 가장 밀접함을 확인했다. 본 연구를 통해 국내에서 금리 스프레드가 경기예측뿐만 아니라 주식수익률과도 인과관계가 있음을 확인한 것에 의의가 있다. 금리스프레드만 사용하여 주식 가격을 예측하는 것에는 한계가 있을 수 있으나 다양한 요인들과 적절히 활용할 경우 강력한 팩터로 역할을 할 것이라 기대한다.

Purpose: Maternal knowledge, positive attitudes and interest toward breastfeeding may improve the sustainability of breastfeeding. This study examined the associations of knowledge, attitudes, and interest toward breastfeeding with the duration of breastfeeding in Korean mothers who used the internet. Methods: We conducted a cross-sectional study of 604 Korean mothers who breastfed their babies. Mothers were recruited through the internet and their knowledge, attitudes and interest toward breastfeeding were assessed using a web-based self-administered questionnaire. Geometric means and odds ratio (OR) with 95% confidence intervals were calculated. Results: Higher knowledge, attitudes, and interest toward breastfeeding were associated with longer duration of breastfeeding in Korean mothers. In particular, mothers who had optimal breastfeeding duration were more likely to be aware of the easiness of breast milk stimulation and breastfeeding, the development of attachment between mother and child, and pleasure from breastfeeding compared to those mothers with shorter duration. The association with optimal breastfeeding duration was more pronounced among mothers who graduated from high school for total attitude scores and total interest scores, compared to mothers who graduated from college or above. Conclusion: The results of this study suggest that it is important to improve maternal knowledge, attitudes, and interest toward breastfeeding in Korean mothers who use the internet as a source of knowledge. Also, the study results imply that the development of strategies to target mothers with relatively low education levels may improve breastfeeding rates.

Purpose - Since COVID-19, the government's expansion of liquidity to stimulate the economy has resulted in an increase in private debt and an increase in asset prices of such as real estate and stocks. The recent sharp rise of the US Federal fund rate and tapering by the Fed have led to a fast rise in domestic interest rates, putting a heavy burden on the Korean economy, where the level of household debt is very high. Excessive household debt might have negative effects on the economy, such as shrinking consumption, economic recession, and deepening economic inequality. Therefore, now more than ever, it is necessary to identify the causes of the increase in household debt. Design/methodology/approach - Main methodology is regression analysis. Dependent variable is household loans from depository institutions. Independent variables are consumer price index, unemployment rate, household loan interest rate, housing sales price index, and composite stock price index. The sample periods are from 2017 to May 2022, comprising 72 months of data. The comparative analysis period before and after COVID-19 is from January 2017 to December 2019 for the pre-COVID-19 period, and from Jan 2020 to December 2022 for the post-COVID-19 period. Findings - Looking at the results of the regression analysis for the entire period, it was found that increases in the consumer price index, unemployment rate, and household loan interest rates decrease household loans, while increases in the housing sales price index increase household loans. Research implications or Originality - Household loans of depository institutions are mainly made up of high-credit and high-income borrowers with good repayment ability, so the risk of the financial system is low. As household loans are closely linked to the real estate market, the risk of household loan defaults may increase if real estate prices fall sharply.

본 연구에서는 1995년부터 1월에서 2015년 10월까지의 5,323개 일별자료로 다변량 GARCH BEKK모형을 이용하여 금리, 환율, 주가 상호간 충격전이효과를 분석하였다. 전체표본기간에서의 변동성 충격전이를 분석한 결과로는 우선 대칭모형상으로 금리변동의 충격은 주가에만 충격을 주었고 환율변동의 충격은 다른 두 변수들에 별다른 영향을 미치지 못하였는데 주가변동은 금리와 환율 모두에 유의미한 충격을 주는 것이 확인되었다. 비대칭모형상으로는 금리의 상승충격은 환율에만, 환율의 상승충격은 금리에만 상호간 유의미한 영향을 미쳤고 주가의 하락충격은 환율에만 유의미한 영향을 미치는 것으로 나타났다. 외환위기국면 소표본기간에서는 비대칭모형에서 금리의 상승충격이 환율과 주가에 영향을 미쳤고 주가의 하락충격은 환율에만 영향을 주는 것으로 나타났다. 또한 글로벌 금융위기국면 소표본기간의 비대칭모형에서는 주가의 하락충격만이 금리에 영향을 주는 것으로 나타났다. 이를 종합하면 한국의 주식시장 변동충격은 나머지 두 변수에 유의미하게 영향을 미쳤고 금리의 충격은 시기별로 주가와 환율에 영향을 미쳤으나 환율의 충격은 전체적으로 그리 크지 않게 나타남으로써 주식시장의 안정화 유도책이 시장변수의 충격을 완화시키기 위한 선결과제임이 입증되었다.

Given the further promotion of economic globalization, China's financial market has also expanded. However, at present, this market faces substantial risks. The main financial and economic risks in China are in the areas of policy, credit, exchange rates, accounting, and interest rates. The current status of China's financial market is as follows: insufficient attention from upper management; insufficient innovation in the development of the financial economy; and lack of a sound financial and economic risk protection system. To further understand the current situation of China's financial market, we conducted a questionnaire survey on the financial market and reached the following conclusions. A comprehensive enterprise questionnaire from the government's perspective, the enterprise's perspective and the individual's perspective showed that the following problems exist in the financial and economic risk prevention aspects of big data and Internet of Things in China. The political system at the country's grassroots level is not comprehensive enough. The legal regulatory system is not comprehensive enough, leading to serious incidents of loan fraud. The top management of enterprises does not pay enough attention to financial risk prevention. Therefore, we constructed a financial and economic risk prevention model based on big data and Internet of Things that has effective preventive capabilities for both enterprises and individuals. The concept reflected in the model is to obtain data through Internet of Things, use big data for screening, and then pass these data to the big data analysis system at the grassroots level for analysis. The data initially screened as big data are analyzed in depth, and we obtain the original data that can be used to make decisions. Finally, we put forward the corresponding opinions, and their main contents represent the following points: the key is to build a sound national financial and economic risk prevention and assessment system, the guarantee is to strengthen the supervision of national financial risks, and the purpose is to promote the marketization of financial interest rates.
