The linkages between asset prices and macroeconomic outcomes are long-standing issue to both economists and monetary authorities. This paper explores the impact of asset prices on output and price in China. It focuses on the impacts of asset prices on the low quantiles of GDP gap and high quantiles of price gaprespectively. The main findings are the following: the influence of stock price gap, stock returns, and money growth on the different quantile of GDP gap and price gap are noticeable different, and there are significant impacts on the left tail of GDP gap distribution and on the right tail of price gap distribution. This implies that the results coming from simple regression will underestimate the economic risk imposed by asset price volatility. Moreover, these results also provide the caveat that one should cautiously distinguish the meaning of asset price gap and asset price growth rate and use them, through their contents are similar in some sense. One implication for monetarypolicy is that authority should interpret the relationship between asset prices and macro-economy in wider perspectives, and make the policy decision taking the impacts of asset prices on the tails of economy.

The asset management system for power distribution is necessary to make efficient use of distribution asset and to devise optimum investment plans. So we developed KDAMS(Korea Distribution Asset Management System) that is adopting reliability indexs, SAIFI and SAIDI, and operator's experiences. This paper presents functions of the system that is reliability management, failure rate management, establishment of optimum investment plan and so on. And it presents the of used algorithms to develop this system.

본 연구는 금리추세에 따른 국내손해보험회사들의 자산운용 실태를 분석하여 문제점을 도출하고, 자산운용전략에 대한 방향을 제안하고자 2009년~2014년까지의 자료를 바탕으로 연구하였다. 손해보험회사들의 자산현황 및 운용자산 내역, 자산배분실태, 유가증권 내역, 총자산수익률을 시계열 분석하였으며, 금리 주가와 총자산수익률의 상관관계 분석을 실시하였다. 연구결과는 안전자산인 국공특수채의 비중은 증가한 반면에 Credit물인 금융회사채 및 위험자산인 주식의 비중은 감소하여 수익성 보다 안정성 위주로 자산운용을 하고 있었다. 금리하락 추세에 따라 총자산수익률도 같이 하락하고 있었으며, 주가지수 추이와 총자산수익률 추이는 일치하지 않았다. 금리와 총자산수익률 간에는 높은 양(+)의 상관계수가 산출되었지만, KOSPI 주가지수와 총자산수익률 간에는 상관계수가 음(-)으로 나타났다.

Value at Risk (VaR) is one of the most common risk management tools in finance. Since a portfolio of several assets, rather than one asset portfolio, is advantageous in the risk diversification for investment, VaR for a portfolio of two or more assets is often used. In such cases, multivariate distributions of asset returns are considered to calculate VaR of the corresponding portfolio. Copulas are one way of generating a multivariate distribution by identifying the dependence structure of asset returns while allowing many different marginal distributions. However, they are used mainly for bivariate distributions and are not widely used in modeling joint distributions for many variables in finance. In this study, we would like to examine the performance of various copulas for high dimensional data and several different dependence structures. This paper compares copulas such as elliptical, vine, and hierarchical copulas in computing the VaR of portfolios to find appropriate copula functions in various dependence structures among asset return distributions. In the simulation studies under various dependence structures and real data analysis, the hierarchical Clayton copula shows the best performance in the VaR calculation using four assets. For marginal distributions of single asset returns, normal inverse Gaussian distribution was used to model asset return distributions, which are generally high-peaked and heavy-tailed.

This paper describes the modeling of the failure rate estimation technique for applying the asset management technique to electric power facilities. There are many modeling techniques to estimate the failure rate. In this paper, the characteristics of the normal distribution, exponential distribution, weibull distribution, and piecewise linear functions are discussed. When evaluating reliability, the evaluation may be less meaningful if the sample data is insufficient. Therefore, Weibull distribution and piecewise linear function are adopted as the most suitable functions for estimating the failure rate of power facilities and the resulting failure rate function is derived.

Purpose: This paper examines whether or not universal banking operating in the asset management business tend to IPO underpricing when they are hosting IPOs in favor of their private interests. Previous studies suggest evidence which indicates that the universal banking operating in the asset management business tend to underestimate offering prices. This paper compares and analyzes the data before and after June 2007 to examine the influence of put-back option on IPO underpricing. Research design, data, and methodology: This paper compares the underwritten prices of IPOs of universal banking with and without asset management business in Korea in order to test such tendency actually exists. Result: We can find that such tendency is not correlated with first-day stock returns but correlated with put-back options. Our paper concludes that the hypothesis that "the universal banking's subsidiary asset management business influences the IPO underpricing" is found to be statistically insignificant. Conclusion: According to our analysis, it cannot be concluded that the interests of operating asset management do not conflict with the ones of underwriting business. However, it is so possible that the asset management companies try to harm the customers' interests, for instances churning and stuffing, it is necessary to scrutinize their behaviors and review the related regulations.

Purpose - For distribution corporate, the method of recognizing sales revenue may be different depending on the type of distribution transaction. Until the change in accounting standards for revenue recognition was made in 2002, the distribution corporate recognized the full amount of sales of goods regardless of the type of transaction. However, in accordance with accounting standards for revenue recognition, which began to be applied in 2003, distribution corporate differ in sales revenue recognition by transaction type. The Purpose of this study is to analyze the impact of sales revenue on the corporate value after the change of the revenue recognition accounting standards. Research design, data, and methodology - We selected a comprehensive wholesale and retail corporate listed on Korea Exchange. The research model extends the Ohlson(1995) model and regresses whether sales revenue affecting the corporate value is discriminatory value relevance between the corporate affected by changes in accounting standards for revenue recognition and those not. Results - The results of the analysis are as follows. First, The average value of stock price, net asset per share, and earnings per share are all higher than those before the change of accounting standards for revenue recognition. However, the average value of sales per share is lower than that before the change of accounting standards for revenue recognition. Second, the relationship between corporate value and net asset per share, earnings per share and sales per share, the coefficient of net asset per share, earnings per share and sales per share are all statistically significant positive value. Therefore, in explaining corporate value, besides net asset per share and earnings per share, sales per share provides additional information. And the coefficient of interaction variable between accounting standard change and sales per share is a statistically significant positive value. This result indicating that after the change of the revenue recognition accounting standards the usefulness of sales revenue has increased. Conclusions - The change in accounting standards for revenue recognition led to a decrease in distribution corporate sales revenue but the higher the relevance of the corporate value of the sales revenue information. These results shows that the change of accounting standards that reflects the transaction type of retailers was a revision to increase the value relevance of sales revenue in valuation of corporate value.

본 연구의 목적은 금리추세가 국내생명보험회사들의 자산운용 실태에 미치는 영향을 분석하여 문제점을 도출하고, 자산운용전략에 대한 방향성을 제시하고자 하였다. 연구방법은 2000년~2014년 동안에 국내 생명보험회사들의 자산현황 및 운용자산 내역, 자산배분실태, 유가증권 내역을 시계열 분석하였고, 총자산 및 자산별 수익률을 분석하였으며, 금리 주가와 운용수익률 간의 상관관계와 회귀분석을 실시하였다. 분석결과는 안전자산인 국공채의 비중은 증가한 반면에 위험자산인 주식의 비중은 감소하여 수익성 보다 안정성 위주로 자산운용을 하고 있었다. 금리와 총자산수익률, 운용자산수익률, 유가증권수익률 간에 높은 양(+)의 상관계수가 산출되었으며, 금리와의 상관관계에서 총자산수익률 보다는 운용자산수익률의 상관관계가 높았고, 운용자산수익률 보다는 유가증권수익률의 상관관계가 더 높았다. KOSPI 주가지수와 운용수익률 간에는 상관계수가 음(-)으로 나타났다. 시사점은 안정성 위주의 자산운용으로 금리하락이 역마진 리스크를 높이고 있어서 자산운용의 변화가 필요하다는 것이다.
