서브프라임 사태로 외환위기시 경외의 대상이었던 미국 투자은행의 몰락은 금융감독의 중요성을 인식하게 되었고, 자본시장의 발전을 도모하기 위해 제정된 자본시장법의 역할 모델이 미국 투자은행이었다는 점에서 우려가 제기되고 있는 것도 사실이다. 본 연구에서는 금융회사의 건전성 규제중 핵심인 자기자본규제가 미래에 출현할 투자은행에 대한 위험을 사전에 예방가능한지에 대해 다음과 같이 검증하였다. 먼저 미국투자은행이 우리나라 자본시장법상 자기자본규제를 적용받았다면 최소규제비율을 초과하는지, 금융투자회사가 미국 투자은행처럼 유동화자산의 재 유동화를 통해 자산 부채를 동시에 증가시키는 경우에도 예방효과가 있는지, 마지막으로 자기자본규제 비율 산정시 사용된 위험액은 내부모형을 통해 산출된 것으로 모형 자체의 문제점은 없었는지를 국내 은행의 내부모형과 비교를 통해 검증하였다. 검증결과 미국 투자은행에 대한 규제비율은 일정 수준 이하로 나왔으나 이는 사후적인 결과로 예방효과가 있다고 결론 내리기 어려우며, 특히 재 유동화를 통한 자산 부채가 동시에 증가하는 경우 현행 영업용순자본비율(NCR)규제가 비율 규제인 관계로 실질적인 제한 효과는 크지 않은 것으로 나타났다. 아울러, 내부모형의 타당성 검증에서도 지역적으로 글로벌하게 다양한 업무를 영위하였던 투자은행과 국내은행간 위험분산 비중이 유의적인 차이를 보였으며, 분산효과의 원인인 위험 요인간 상관관계 방향이 동일한 점등을 감안할 때 내부모형 자체의 치명적인 결함은 있다고 보기는 어려웠다. 따라서 복잡하고 이해하기 어려운 건전성 규제 비율이 사전적인 예방에 크게 도움이 되지 않고 한계가 있다면, 구체적 실행도구로서 부채비율과 같은 단순한 기준이 오히려 유용할 수 있다는 점이다.

The world financial markets are inter-linked in ways that varies according to market and time. We examine the causality of change focusing on the Korean market as related to the U.S. (S&P 500), Japan (Nikkei 225), Hong-Kong (HSI), and European (DAX) markets. In order to capture time-varying causality running from and to the Korea stock market, we apply the Granger causality test under a VAR model with a wild bootstrap rolling-window approach. We also propose a new concept of a significant causality ratio to measure the intensity of the Granger causality in each time unit. There are many asymmetric strengths in mutual Granger causal relationships. Moreover, there are cases with significant Granger causal relations only in one direction. The period with the most severe Granger causality both running from and to the KOSPI market is the GFC. The market that formed the two-way Granger causal relationship with the KOSPI market for the longest period is the S&P 500. The HSI and DAX markets have the strongest two-way Granger causal relationship with the KOSPI shortly after 2000, and the Nikkei market had the strongest two-way Granger causal relationship with the KOSPI market before the Asian financial crisis.

The issue of environmental crisis encourages companies to develop strategies and programs which incorporate social and environmental considerations into their processes. The objectives of this study are to identify the strategies used in implementing corporate social and environmental reporting (CSER) and to investigate the impact of these strategies on organization performance. This study uses as its sample companies listed on the Indonesia Stock Exchange (IDX) and engaged in environmentally sensitive business activities and applies content analysis to their annual reports. The data used in the study is secondary data in the form of annual and sustainability reports of companies, and primary data in the form of interviews. The results show that companies use both reactive and proactive strategies in reporting their social and environmental activities. The study also identifies the impacts of such reporting on both the financial and non-financial performances of the investigated companies. The study contributes to the social and environmental accounting literature by exploring the motivations and strategies of companies in their CSER. The empirical results will provide important insights into the influence of the strategies employed by companies in their corporate social and environmental reporting and the impacts of such strategies on organizational performance.

This paper examines the relationship between ownership structure and level cash holdings in an emerging country, namely, Saudi Arabia, by constructing a corporate governance mechanism (foreign ownership, family ownership, institutional and managerial ownership). This paper uses data from 100 listed firms at Saudi Stock Exchange (TADAWUL) from 2011 to 2019. The firm's decision to hold cash has come to the fore in the last two or three years as a result of the recent global financial crisis, and the impact that this has had on the firms' ability to raise funds from external sources. Using the random-effect generalized least square (GLS) regression model, the findings reveal that foreign and family ownership negatively influences cash holdings, while managerial ownership has a positive association with cash holdings. Further, institutional ownership did not have a direct effect on cash holdings in Saudi Arabia. Our results suggest that ownership structure include foreign ownership, family and managerial ownership is an essential vehicle to promote the performance of cash holding of all the 100 public-listed non-financial firms in Saudi Arabia. We recommend that sound policies should be targeted toward foreign ownership, family, and managerial ownership since they are essential to improve cash holding in Saudi Arabian firms.

This paper examines the effects of regulatory capital on a bank's profitability and risk. We employ annual data from Vietnamese commercial banks from 2005 to 2020 and use the dynamic GMM regression method to address the potential endogeneity issue, more suitable for panel data with relatively low time dimensions. Our panel regressions indicate that higher regulatory capital would significantly improve the bank's profitability and lower the bank risks. In particular, a one percent increase in the regulatory capital would significantly increase the bank's return on assets by 1.9%. We further explore the heterogeneous impacts of regulatory capital on the Vietnamese bank's performance across bank characteristics. We find that smaller, non-state-owned and non-listed banks would benefit from stringent regulatory capital requirements. The improvements in bank performance are mainly driven by reductions in the risk premium of the banks, resulting in lower funding costs and higher profitability. These findings are essential since Vietnam, as an emerging market, has only implemented the Basel II reform recently on a stable and fast-growing background rather than as a reaction to the global financial crisis. Thus, our empirical results support stringent regulatory capital in emerging countries to ensure a stable banking sector and boost economic growth.

Combining the strength of both Mixed Data Sampling (MIDAS) Regression and realized variance measures, this paper seeks to investigate two objectives: (1) evaluate the post-sample performance of the proposed weekly Realized Variance-MIDAS (RVar-MIDAS) in one-week ahead volatility forecasting against the established Generalized Autoregressive Conditional Heteroskedasticity (GARCH) model and the less explored but robust STES (Smooth Transition Exponential Smoothing) methods. (2) comparing forecast error performance between realized variance and squared residuals measures as a proxy for actual volatility. Data of seven private equity mutual fund indices (generated from 57 individual funds) from two different time periods (with and without financial crisis) are applied to 21 models. Robustness of the post-sample volatility forecasting of all models is validated by the Model Confidence Set (MCS) Procedures and revealed: (1) The weekly RVar-MIDAS model emerged as the best model, outperformed the robust DAILY-STES methods, and the weekly DAILY-GARCH models, particularly during a volatile period. (2) models with realized variance measured in estimation and as a proxy for actual volatility outperformed those using squared residual. This study contributes an empirical approach to one-week ahead volatility forecasting of mutual funds return, which is less explored in past literature on financial volatility forecasting compared to stocks volatility.

While the issue of RMB (Renminbi, Chinese Yuan) revaluation became the focus of world attention in 2003, the reform of the RMB exchange rate regime in 2005 didn't fundamentally solve the RMB appreciation problem, and even in 2008 the global financial crisis made RMB appreciation face new challenges and risks. It appears that the rise in RMB value is caused by supply exceeding demand in China's foreign exchange market; however, intrinsically it is due to the asymmetry in RMB exchange rate formation mechanism. The export tax rebates policy implemented by Chinese government is one of the leading causes of the asymmetry. This study constructs a transmission model between export tax rebates and foreign exchange rates, and applies the Granger Test to validate the causality between kernel variables based on correlative data from 1994-2011, and uses the error correction method to analyze the quantified relations of kernel variables, and finally gets the contribution rate of export tax rebates to RMB appreciation.

Amid a general rise in protectionism and a trade war between the world's two largest economies, this paper analyzes changes in gains from trade for the world over a decade marked by rapid global economic integration preceding the global financial crisis of 2007-08. It employs state-of-the-art quantitative trade models based on the gravity equation to estimate autarky gains from trade, as well as a recently introduced ANOVA-type structural estimation of the gravity equation to obtain trade costs free of residual trade cost bias. Between 1995 and 2006, the cost of moving to autarky increased by about 45% on average. A decomposition exercise suggests most of the increase in autarky gains from trade on average was due to increases in import shares in total spending, with a limited role for reallocations of spending across sectors with varied trade elasticities. Changes in trade costs between 1995 and 2006 are found to have increased autarky gains from trade, as measured in 2006, by up to 100%.

The purpose of this study is to analyze the technical and cost efficiency of Air Transport Industry on Global strategic alliances. In particular, this study develops Stochastic Frontier Approach for accurate judgement. Based on 20 major international airline corporations related with strategic alliances during the period 1995-2001, we find that alliances make a significant contribution to efficiency. On the other hand, it is found that the level of contribution to efficiency is different according to alliances. These results also changed greatly between pre- and post- Asian financial crisis period.

본고에서는 구직률과 이직률을 이용해서 한국의 자연실업률을 추정하였다. 추정 결과, 한국은 IMF 경제위기 이후 구직률과 이직률이 모두 상승하는 추세를 보였으나, 자연실업률의 추세가 상승했다고 결론을 내릴 수는 없었다. 칼만필터 추정법에 의한 구직률, 이직률, 자연실업률의 추세 간의 관계를 볼 때, '일자리창출(Job Creation)'과 '일자리 파괴(Job Destruction)'가 동반 상승했음을 추론할 수 있다.
