For the behavior of the wholesale spot price, a regime switching model with time-varying transition probabilities was estimated using the data from the PJM (Pennsylvania-New Jersey-Maryland) market. By including the temperature as an explanatory variable in the transition probability equations, the threshold effect of changing regime is clearly enhanced. And hence the predictability of the price spikes was improved. This means that the model showed a very clear threshold effect, with a low probability of switching for low loads and low temperatures and a high probability for high loads and high temperatures. And temperature showed a clearer threshold effect than load does. This implies that weather-related contracts may help to hedge against the risk in the cost of buying electricity during a summer.

전환사채에 대한 연구는 전환사채의 가치와 최적상환정책에 대한 연구, 기업의 재무의사결정에 있어서 전환사채의 역할 및 기능, 그리고 전환사채의 발행이 주식가격에 미치는 영향을 분석하는데 중점이 주어져 왔다. 전환사채의 가격결정모형에 대한 연구와 전환사채 발행이 주식가격에 미치는 영향에 대한 연구는 많지만, 전환사채를 발행한 기업의 재무적 특성과 발행동기에 대한 연구는 상대적으로 적다. 본 연구는 이러한 점에 착안하여 1987년 이후 발행이 증가하고 있는 국내전환사채를 연구대상으로, 전환사채 발행기업과 전환사채 비발행기업의 재무비율을 변수로 선택하여 전환사채를 발행한 기업의 채무적특성을 분석한다. 그리고 기업들이 실제로 어떤 동기에서 전환사채를 발행하고 있는가를 설문조사를 이용하여 살펴본다.

파생금융상품이란 주식이나 채권과 같은 기준자산에 대해서 발행되는 2차 금융상품으로써 기존의 재무이론에서는 수리적 모형에 기반을 둔 가격결정모형을 이용하여 가치를 평가하였다. 그러나 이러한 전통적인 가격결정모형은 복잡한 현실세계를 단순화시키기 위한 제반 가정을 요구하기 때문에 이러한 가정이 현실에 부적합한 경우에는 모형가격이 실제가격으로부터 커다란 괴리를 갖게 된다. 본 연구에서는 전통적인 가격결정방법의 단점을 극복할 수 있는 자료 의존적인 인공신경망기법을 제시하고 대표적인 파생금융상품인 국내 전환사채의 가격결정에 적용해 봄으로써 그 가능성을 제시하였다. 인공신경망기법을 전환사채의 가격결정에 적용한 결과 전통적 가격결정방법에 비해 평균절대오차를 70%정도 줄일 수 있다.

The purpose of this study is to find out how much the investment effect of convertible bond(CB) is from the perspective of investors and to present efficient investment plans to investors. The research method is to investigate the coupon interest rate, maturity interest rate, conversion price, etc. for CBs. As a result of the study, it was analyzed that CB's investment efficiency was low because the conversion price excess days ratio was only about 1/4 of the conversion date. The conversion day yield was -6.3% and the maturity day yield was -5.2% on average. It was analyzed that the number of stocks with negative conversion day yield was 2.4 times higher than the number of positive stocks and 3.7 times higher than the number of positive stocks with a maturity day yield, so the expected return on equity conversion of CB was low.

Although the factors that affect the width of latitude of price acceptance is well documented, the attempt to develop a practice-oriented methodology to calibrate the region of price insensitivity (i.e., a latitude of price acceptance) for a given individual brand has been relatively rare. The researcher aims to try to full this gap by developing a conjoint analysis-based procedure that can be applied to many industries. Furthermore, we examine the difference in the latitude of price acceptance between on- and off-line transaction in stock industry in Korea. The conjoint analysis-based procedure was applied to measure the disaggregate price response curve for individual stock investment both on- and off line transaction channel. The curves from the samples enable us to estimate the individual choice probabilities corresponding to applied price points. Using t-test the differences in mean choice probabilities between the list price and another price point were tested, through which we can get the latitude of price acceptance for a given brand in stock market. These procedures were tested in on- and off-line stock market in South Korea. The results showed that investors on off-line channel have wider latitudes of price acceptance than the investors on on-line transaction system.

본 연구는 최근 우리나라 시장에서 의결권이 없는 우선주 가격이 의결권이 있는 보통주 가격보다 높게 형성된 이상 현상의 원인을 분석하였다. 1990년부터 2003년까지 우선주를 발행한 기업의 보통주와 우선주를 비교 분석한 결과, 우선주 시장은 14년간 지속적으로 규모가 축소되고 유동성이 하락하였음을 알 수 있었다. 우선주 가격이 보통주 가격보다 높게 형성된 종목은 외환위기이후인 1998년부터 급증하여 전체 우선주 발행종목의 40%까지 이르게 되었다. 이들 우선주는 대부분 경영실적이 악화된 기업에 해당하며, 발행물량이 극히 소규모이고 외국인 투자자가 외면하는 우선주들로서 단기간에 매우 높은 빈도의 거래가 이루어 진 경우가 많다. 즉, 소수의 투자자에 의해 쉽게 가격이 왜곡된 후, 거래량이 없이 기세로서 가격이 표시되어 유지된 경우가 많다고 추론할 수 있다. 이들 우선주는 원래에는 전환사채로 발행되었다가, 훗날 우선주로 전환된 경우가 대부분이었다.

If the conversion rate of jeonse price to monthly rent is the market interest rate or the landlord's expected return, then the conversion rate of jeonse price to monthly rent in the country should be the same. However, the conversion rate of jeonse price to monthly rent has always been higher than the market interest rate. This study identifies the supply cost components of rental housing as a risk premium in the presence of current housing prices, market interest rates, depreciation costs, holding taxes, and leases, and identifies the relationship between the current housing prices and each factor. Housing rent is expressed as the current price. This overcomes the shortcomings that implicitly assume fluctuations in housing prices or do not include current housing prices in the conversion rate of jeonse price to monthly rent. This study found that the conversion rate of jeonse price to monthly rent is the required rate of return or required rate of renter, not market interest rate, by expressing the supply cost of rental housing as a combination of components. This not only explained the fact that the conversion rate of jeonse price to monthly rent was always higher than the market interest rate, but also explained the regional differences. It also explained why the conversion rate of jeonse price to monthly rent varies by type of housing.

CB(Convertible bond) is mezzanine security that have the characteristics of bonds and stocks. From the perspective of investors, the purpose of the research is to empirically investigate the degree of investment efficiency of CB and to suggest efficient investment plans. The research method investigated the maturity interest rate, conversion price, and conversion date for CB, and then linked it with daily stock price fluctuations after the conversion date to determine the degree of investment efficiency and stock conversion effect of CB. As a result of the study, it was analyzed that the ratio of the conversion price exceeded days was only about 1/4 of the conversion date, so the investment efficiency was low. The conversion day yield was -6.3% on average and the maturity day yield was -5.2% on average, showing a minus return on average, which was calculated differently from investor expectations. It was analyzed that the number of stocks with a minus conversion day is 2.4 times greater than the number of plus stocks and 3.7 times more than the number of plus stocks with a minus maturity return, so the expected return on stock conversion of CB is low. The research contribution was derived from the problem that the expected rate of return of CB is not high, and it is that the investor's point of view when purchasing CB was established.
