신용평가제도는 오늘날 그 영향력이 강력해져 사실상 세계자본시장의 문지기역할을 하고 있다. 본 논문에서는 이와 같이 신용평가기관의 중요성과 영향력의 증대와 더불어 이들 평가기관의 활동에 대한 비판과 감시가 커지고 있는 이때에 아직 선진수준에 미치지 못하는 국내신용평가기관들의 현황과 평가체계를 살펴보고 선진국의 신용평가기관들과 비교해 봄으로써 앞으로 나아갈 방향을 모색해보고자 하였다. 국내 신용평가기관들의 현황을 살펴본 결과 신용평가절차에 있어서 기준이 경영상태, 성장성, 그리고 재무구조의 건전성에 있어야 함에도 불구하고 이러한 기본적인 요인들의 영향력은 미미한 반면, 비공개적이고 불투명하며 비경제적인 요인들이 중요한 비중을 차지하고 있었다. 이에 반하여 선진신용평가기관들의 분석결과는 그 신뢰도에 믿음을 가질 수 있고, 대내외적인 공신력을 인정받고 있으며, 평가과정이 매우 주관적이어서 그 내용을 모두 공개하지 않지만, 국내의 신용평가과정보다는 투명성을 인정받고 있다는 것도 사실이다. 따라서 국내신용평가기관들의 나아갈 바를 살펴보면 다음과 같다. 첫째, 비재무적 요인의 평가기준에 대한 인식의 재정립이 요구되고 있다. 장기적인 시각으로 비재무적 요인에 대한 평가기준과 방법에 대한 체계의 정립이 요구되며, 전문적이고 객관적이면서도 뚜렷한 평가기관의 주관이 있는 평가가 이루어져야 할 것이다. 둘째, 신용평가방법과 기준의 강화로 대외적인 공신력을 얻도록 해야 한다. 이를 위한 방안의 하나로 성장성, 수익성, 그리고 안정성 비율 모두를 반영할 수 있는 신용평가모형을 개발하고, 자기자본비율의 대폭적인 상승이나 현금흐름의 양호여부, 경제적 부가가치(EVA), 고정장기적합률의 이행기준의 설정 등에 대한 평가기준의 재정립이 강구되어야 할 것이다.

The purpose of this research is to assess the efficiency of the airline's route. The revenue source of low cost airline carriers is not various unlike regular airline carriers, because they are operating only domestic and international flights for a country of close proximity. In particular, domestic low-cost airlines in Korea can't provide cargo transport services but rely on passengers and additional services to generate profits. Therefore, it is absolutely important to maintain a low cost and effective passenger transport line. This study will suggest the way to improve efficiency of route operated by low-cost airlines. Analysis method is DEA. The input parameters and output results were selected by existing research. Based on the results of this study, it will be able to assist establishing routes and selling strategies of the low-cost airlines.

Economic evaluation of the manufacturing technology of high-value chemicals through the carbonation reaction of carbon dioxide contained in the flue gas was performed, and analysis of the IRR (Internal Rate of Return) and whole profit along the production plan of the final product was conducted. Through a carbonation reaction with sodium hydroxide that is generated from electrolysis and by using carbon dioxide in the combustion gas that is generated in the power plant, it is possible to get a high value products such as sodium bicarbonate compound and also to reduce the carbon dioxide emission simultaneously. The IRR (Internal Rate of Return) and NPV (Net Present Value) methods were used for the economic evaluation of the process which could handle carbon dioxide of 100 tons per day in the period of the 20 years of plant operation. The results of economic evaluation showed that the IRR of baseline case of technology was 67.2% and the profit that obtained during the whole operation period (20 years) was 346,922 million won based on NPV value. When considering ETS due to the emissions trading enforcement that will be activated in 2015, the NPV was improved to a 6,000 million won. Based on this results, it could be concluded that this $CO_2$ carbonation technology is an cost-effective technology option for the reduction of greenhouse gas.

This paper investigates the influence of stock-level left-tail risk, which is defined using Value-at-Risk(VaR) estimates of past one-year daily stock returns, in the expected stock returns in the Korean stock market. Our results are summarized as follows: First, monthly-constructed zero-cost portfolios that buy (shortsell) the highest (lowest) left-tail risk decile in the previous month exhibit an average monthly return (called left-tail risk premium) of -2.29%. Second, Fama-MacBeth cross-sectional regressions suggest that left-tail risk in the previous month shows significant and negative explanatory power over return in this month, after controlling for various firm characteristics such as firm size, B/M, market beta, liquidity, maximum daily return, idiosyncratic volatility, and skewness. Third, the stocks with larger recent month loss have lower returns in the next month. Fourth, the magnitude of left-tail risk premium is negatively related with lagged market-level volatility. These results support the hypothesis from a perspective of behavioral finance that the overpricing of stocks with left-tail risk is attributed to the investors' underreaction to it.

An aim of this paper is to test four hypotheses on price volatility in the $CO_2$ emission markets focusing on European Climate Exchange(ECX) in the EU Emission Trading Schemes(EU ETS) and Chicago Climate Exchange(CCX). I expect that, due to an influx of market information, a differently designed exchange market would bring a different price volatility, and various types of emission permits in the same exchange market would result in the same effects on the price volatility. Major findings are that the price volatility is same regardless of the types of emission exchange markets and emission permits comparing the rate of returns. However, comparing the GARCH variance, the volatility between ECX EUAs and CCX-CFIs and the volatility between EUAs(CERs) futures and daily futures are different with the exception of the volatility between EUAs futures and CERs futures. In conclusion, the price volatility depends on the types of exchanges and the types of emission permits.
