본고(本稿)는 1970~86년의 기간중 우리나라 주택시장(住宅市場)에서의 수요(需要) 및 공급결정요인(供給決定要因)을 분석하고 주택관련자금(住宅關聯資金)의 흐름을 연간(年間) 시계열자료(時系列資料)를 이용하여 모형화함으로써 주택금융(住宅金融)의 주택수급(住宅需給)에 대한 영향을 알아보았다. 주택부문(住宅部門) 순투자(純投資)로 파악된 수요측면(需要側面)에서는 민간소비지출(民間消費支出)로 대치된 항상소득(恒常所得)이 중요한 결정요인(決定要因)이었고 주택부문(住宅部門) 총투자(總投資)로 파악된 공급측면(供給側面)에서는 주택사업자(住宅事業者)의 기대수익률(期待收益率) 및 주택금융취급기관(住宅金融取扱機關)의 자금여유 등이 중요한 결정요인으로 나타났다. 또한 본고(本稿)에서는 가치기준(價値基準)의 새로운 주택가격지수(住宅價格指數)를 산정함으로써 기존(旣存)의 주택연구사례(住宅硏究事例)에서 지적되어 온 주택가격(住宅價格)에 대한 자료부재(資料不在)를 극복하였다.

본 논문의 연구목적은 통화선물시장(通貨先物市場)을 대상으로 선물거래를 할 경우에 발생하는 거래비용(去來費用)의 측정(測定) 및 결정요인(決定要因)들을 규명하는데 있다. 먼저 선물시장에서 광의의 거래비용을 정의하고 이를 토대로 일별 총거래비용을 추정하였다. 추정된 총거래비용의 결정요인을 추출하기 위해 중회귀분석을 수행한 결과 거래대상통화와 가격표시통화간의 만기까지의 이자의 차이와 선물가격 의 조건부분산(條件附分散)이 총거래비용에 영향을 미치고 있음을 알 수 있었다. 또한 총거래 비용에서 이자의 차이를 제외시킨 순거래비용을 분석한 결과 거래량이 순거래비용과 양(%)의 유의적인 관계가 있음을 확인할 수 있었다. 이러한 관계를 종합해 볼 때 통화선물시장(通貨先物市場)에서의 거래비용(去來費用)은 이자요인(利子要因)과, 위험을 나타내는 조건부분산(條件附分散) 및 거래량(去來量)에 의해 그 크기가 결정된다고 결론지을 수 있었다. 즉 선물거래시의 거래비용의 크기는 이자차이(利子差異)뿐만 아니라, 분산(分散)과 거래량에 의해서도 영향을 받는다고 할 수 있었다. 이같은 본 연구의 결과는 스프레드를 주된 거래비용으로 정의해온 기존의 연구와는 차별적이라는데 그 의의가 있다.

In the existing ship sales market, prices determined based on the prices of similar ship types that recently traded. ince the 2008 financial crisis, ship prices have fluctuated, and ship price criteria have become ever more necessary to the imminent value of the ship. Therefore, this research used the hedonic price model to estimate imminent values of ships. In this study, the influence on ship prices was analyzed by the value of each characteristic and an estimated functional formula was. Out of the four models suggested by the hedonic price model, an optimal model was selected with variance inflation factors and a stepwise selection. For this, the influence of determinants of ship prices was analyzed based on actually traded ships and characteristic data. The selected model s the Log-Line model; as a result of regression analysis, eight variables, including DWT, Age, Market Value, Short-Term Charter, Long-Term Charter, Enbloc, Special Survey Due and Builder were to affect the ship price model. This model is expected to be useful for objective and balanced ship price evaluation.

This study focuses on the prediction and factors of apartment prices in Seoul using a convolutional neural networks (CNN) model that has shown excellent performance as a predictive model of image data. To do this, we consider natural environmental factors, infrastructure factors, and social economic factors of the apartments as input variables of the CNN model. The natural environmental factors include rivers, green areas, and altitudes of apartments. The infrastructure factors have bus stops, subway stations, commercial districts, schools, and the social economic factors are the number of jobs and criminal rates, etc. We predict apartment prices and interpret the factors for the prices by converting the values of these input variables to play the same role as pixel values of image channels for the input layer in the CNN model. In addition, the CNN model used in this study takes into account the spatial characteristics of each apartment by describing the natural environmental and infrastructure factors variables as binary images centered on each apartment in each input layer.

Participants can use the allowances and offsets for implementing the compliance in the Emissions Trading Scheme(ETS). There are alternative commodities which are different prices it gives the opportunities to reduce the compliance costs and get the arbitrage. This study analyzes the price driver of spread which is the difference between EUA and sCER using AR-GARCH model, EUA and CER during the Phase 2 in EU ETS. The results show that there are common elements which impacts the EUA and sCER and also different elements between them. EUA and sCER get the effects from energy price and economic criteria such as coal price and financial crisis as common elements. However them get the effects from electric price, policy criteria such as restricted CERs and difference price between EUA and ERU price as different elements. The results shows that spread will be widen if energy price increase, especially oil and electric price give more impacts the spreads. This study has the means that it explains the reason why the spreads will broaden sharply in 2012. And it also suggests the price driver of spread during the whole period of Phase 2. In addition, this study shows that political aspects maybe become the main criteria of price change with structural elements shch as energy price in Korea ETS which starts in 2015.

As the market-based spectrum policy is introduced, an interest in the economic value of the frequency is increasing. Research and practical applications concerning the methodology for the estimation of the economic value of the frequency and its determinants are actively engaged, which are used for setting a reserve price and bid price of spectrum auction and a spectrum clearance cost. In this study, by the analysis of the spectrum valuation methodology, we derive the changes in the factors affecting the valuation and propose to apply improved. In the model frequency value is consist of technical value, commercial value and strategic value, we find the dynamics of fluctuation factors and suggest how to apply them to spectrum policy.

지금부터 4년전 다시 말해 현재의 국제원유시장의 공급과잉 사태가 발생되기전 원유의 현물가격은 공시판매가격보다 웃도는 상태를 지속했었다. 원유가격 형성의 기본이 되는 현물시장의 가격수준이 공시가격의 방향을 예시하는 나침판 역할을 하기 때문에, 원유의 안정적인 공급을 확보키 위한 일환으로 산유국과 장기계약을 선호하던 당시, 석유소비국들은 로테르담 석유시장을 원망하는 태도로 바라보았다. 왜냐하면 악덕거래업자들의 조작으로 현물시장 가격은 계속 상승일로에 있었기 때문이다. 산유국정부들은 표면적으로 가격은 시장의 원리에 입각해서 형성되어야 한다고 주장하면서 그들의 공시가격이 현물가격보다 낮다는 점을 들어 공시가격 수준을 합리화했던 것이다. 이하에서 현물시장 가격 형성에 영향을 주는 요인들을 설명하기로 한다. <편집자 주>

In Korea's drama industry, a production factor has several prices, not one, bucking the general economic theory. The price changes depending upon the broadcaster, the producer, and even the genre. The price gets determined by such factors as the scarcity, the substitutability, the overall budget size, and so on. For star actors, the price stands for their popularity and ego, which makes them strive so desperately for a higher pay than competitors. The rise of the production factor price has outpaced that of the production budget, to cause undesirable structural problems. It is deemed that the running guarantee could be a way to rationalize the pricing system for production factors in Korea.

Because local cities are different from large cities, they need to reflect their own characteristics of housing market. Thus in order to obtain useful implications for the establishing sound housing market in Jinju City, this paper investigated the characteristics of spatial distribution and determinant factors that affect apartment price in Jinju City. GIS representation of the apartments showed that most of old and small apartments were built in 'land readjustment project' areas executed in 1970s. On the contrary, new and large scale apartment complexes were built quite recently and distributed in the western and southern parts of the city. Next, in order to examine the factors which affect apartment price, this paper subtracted firstly several variables from the related studies. However in order to avoid multi-colinearity, variables were summarized by means of factor analysis. Then, setting apartment price as a dependant variable, 12 hedonic price models were established with 33 independent variables. As results, building age, floor area, accessibility to university and hospital, accessibility to arterial road, and stair-type building were turned out to be significant. These results will be used in making the supply and allocation plan of urban facilities and housing. Finally as conclusions this paper emphasized the need of periodic analysis of local housing market and establishing detailed housing information systems.
