국내 배출권 시장에서는 시장안정화 조치 발동에도 불구하고 배출권 가격의 불확실성 문제가 지속적으로 대두되고 있다. 그리고 2021년 10월 정부가 발표한 2030 감축목표 상향안을 고려해볼 때 배출권 가격의 불확실성 완화를 위한 실질적인 대안 마련의 필요성이 높아지고 있다. 본 연구는 배출권 시장의 가격 불확실성 완화 수단인 가격상하한제가 배출량과 감축비용에 미치는 정량적인 영향을 살펴본다. 분석을 위한 주요 시나리오는 탄소세, 배출권거래제, 가격상하한제하 배출권거래제 3가지로 구분되며, 배출량 불확실성을 반영하기 위해 몬테카를로 시뮬레이션을 기반으로 비교 분석하였다. 연구 결과는 다음과 같다: 1) 상하한제 도입 시에는 다른 시나리오 대비 현저히 낮은 감축비용으로 배출목표를 달성할 수 있다. 상향된 감축목표에서는 0.1%의 초과배출이 발생할 수 있으나 상하한 간격이 넓은 경우 안정적인 목표달성이 가능하다. 2) 이월을 제한할수록 감축비용은 상승한다. 이는 이월 제한 정책이 기간 간 효율성을 저해하여 비용효과적인 감축을 어렵게 만들기 때문이다. 3) 상하한제하에서 정부의 배출권 순구매량이 발생해도 순수입은 양이 될 수 있다. 정부는 배출권을 상한가에서 판매하고 하한가에서 구매하기 때문이다.

The golf industry has become the center of attention for recreational activities in the participant sport market; however, there has been little effort made to understand golf consumer and their consumption behavior using the concept of 'recreational specialization' which segments the golfers based on level of specialization in golf. The purpose of this study was to explore the differences in the relationships among perceived service quality, price of playing golf, overall customer satisfaction with the course, and a player's intention to revisit the same golf course based on the magnitude of recreation specialization in golf. Four public and two private golf courses from the southeastern state of the United States were randomly chosen from a list in a golf magazine. The 365 surveys among 417 participants were ultimately analyzed. Multiple group analysis was conducted in order to investigate differences in relationships among service quality, price, customer satisfaction, and revisit intentions between groups based on the level of recreation specialization. The key findings were 1) for more specialized golfers, satisfaction with price did not affect overall customer satisfaction or revisit intention, however, service quality significantly influenced both overall customer satisfaction and revisit intention, 2) for less specialized golfers, satisfaction with price significantly influenced overall customer satisfaction but did not affect revisit intention. Knowledge about which the determinants of satisfaction are different between more and less specialized golfers could provide a better understanding of how different marketing strategies should be implemented for different specialized levels of golfers.

The Purpose of this research was to propose positioning strategies of urban park (UP) based on the assessment of location characteristics at cheongju city. To do that, this research found out urban park service area (UPSA) using GIS network analysis and built socio-economic attribute database, UP map, and other public service thematic maps such as public transportation, education, child-care, and convenience services. And this research analyzed spatial and attribute data using Pearson's correlation analysis, multiple linear regression, and binary logistic regression methods. As a result of this analysis, 1) the nearer neighborhood park and children's park, the higher land price and assumption income level (AIL). 2) children's parks were closed to living convenience facilities such as bank, hospital, and convenience store. 3) land price, AIL, population, and other public services level (PSL) in UPSA were higher than that of non-UPSA. 4) The higher land price, AIL, population, and other PSL, the higher urban park service level. The results of this research may contribute to resolve the regional UP unbalance and to improve UP service level as public service.

This study conducted to predict the stock market prices based on the assumption that internet news articles might have an impact and effect on the rise and fall of stock market prices. The internet news articles were tested to evaluate the accuracy by comparing predicted values of the actual stock index and the forecasting models of the companies. This paper collected stock news from the internet, and analyzed and identified the relationship with the stock price index. Since the internet news contents consist mainly of unstructured texts, this study used text mining technique and multiple regression analysis technique to analyze news articles. A company H as a representative automobile manufacturing company was selected, and prediction models for the stock price index of company H was presented. Thus two prediction models for forecasting the upturn and decline of H stock index is derived and presented. Among the two prediction models, the error value of the prediction model (1) is low, and so the prediction performance of the model (1) is relatively better than that of the prediction model (2). As the further research, if the contents of this study are supplemented by real artificial intelligent investment decision system and applied to real investment, more practical research results will be able to be developed.

The purpose of this paper is to test whether prices of mobile communication service reflect their varying degrees of call quality, controlling for other service attributes. As, in fact, service is intangible goods difficult to measure its value, this paper makes use of econometric model, hedonic price analysis. Hedonic price analysis, has ever been applied in public or environmental economics, is employed and produces estimates of the prices (or the contributions toward the total price) for each characteristic. This paper applied hedonic technique to the value measurement of a service property for the use of Korean mobile communication. This paper uses actual transaction prices of mobile communication service to determine whether or not the market functions in pricing call quality of mobile communication service. Finally, this show that the willingness to pay of consumer increases as call quality increases and so market makes prices on call qualities. Thus, major concern in this paper is about value measurement o service quality, and also suggest of the possibility to determine call quality value (or price) of mobile communication service.

By analyzing the impact of oil prices on economic growth, this study has shown a new insight into the link between oil price inflation and economic growth. The primary goal of this study is to determine if oil prices are pro-growth or anti-growth. To provide empirical proof, the series data for both the core and control variables from 1972 to 2020 was used to justify the association on empirical grounds. To account for the presence of a unit root, the Augmented Dickey-Fuller Test was used, and after making the series compatible for co-integration, the Autoregressive distributed lag model was used to determine the empirical estimate. Additionally, the empirical models were used to diagnose heteroscedasticity and autocorrelation. The reference point model reveals that in developing nations like Pakistan, economic growth is anti-growth with an increase in prices, and it responds negatively to economic growth in the long and short run. As a result, oil price inflation in Pakistan fails to have a significant beneficial impact on economic growth in both the long and short run, but it does raise the general price level in the economy.

Scooters are a popular way to get around on your own in many places, such as Taiwan, India, Thailand, etc., because they are easy to move around in, small, and cheaper to buy than cars. On the other hand, traditional scooters that run on fossil fuels put some pollution into the air and add to problems like global warming and air pollution. Switching from scooters that run on fossil fuels to electric scooters can help clean up the air in cities with much pollution. To promote the use of electric scooters, it's important to know how consumers feel about them. The current study investigates consumers' purchase intentions for electric scooters. Based on the questionnaire survey results (n = 567), we found that consumers' environmental concerns, price consciousness, and perceived subjective norms are associated with electric scooter purchase intention. Consumers with price consciousness may choose fossil-fuel-powered scooters because they consider electric-powered scooters more costly, although environmentally friendly. The study gives researchers and practitioners a glimpse into consumers' environmental concerns and subjective norms for a sustainable product.

A survey on Korean families′purchase of fresh fruits and vegetables was conducted to increase understanding of families′food decision making. Two hundred ninety seven families with at least one elementary-school age child were selected from four elementary schools to complete a questionnaire during April, 2001 in Gyeongju, Korea. Descriptive statistics, Chi-square test, T-test, and ANOVA statistics were used to analyze the data. The major findings are as follows: Families bought fresh fruits and vegetables at the public markets or the farmer′s markets and a large supermarket most frequently in both summer and winter. Families grew produce by themselves and bought them from farmers directly least frequently in both summer and winter. Families whose housewives had less than middle school education brought fruits and vegetables from Agricultural Co-ops and grew thens by themselves more frequently compared to those who had higher education. On the other hand, families whose housewives had graduated from 4 year college bought fruits and vegetables from large supermarkets more frequently compared to those who had lesser education. "Quality"and "safety production"of fruits and vegetables and "clean environment of store"were the three most important factors when they decided the place to buy fruits and vegetables. "Being treated as a valuable customer" and "ease of finding things"were the two least important factors. Families whose housewives were in their thirties valued "cleanness of the store"and "being treated as a valuable customer"important factors when they decided the place. Families whose housewives had less than middle school education thought that price, availability of public transportation, and availability of locally grown food were the important factors for deciding the place compared to those who had higher education. The price was the factor which low-income families thought important for decision making on the place to buy fruits and vegetables.

한국사회에서 부동산에 대한 많은 관심에도 불구하고 가격예측은 쉽지 않으며, 그중에서도 아파트는 주거공간인 동시에 투자의 의미도 지니고 있어 더욱 가격예측은 쉽지 않다. 아파트 가격에 영향을 주는 요인은 매우 다양하며 지역에 따른 특성도 있다. 본 연구는 경기도 S시 아파트 매매가격에 영향을 주는 요인들과 특성을 도출하기 위해 수행되었다. 일반적으로 지하철 접근성이 좋을수록 아파트 가격이 높다고 파악되나, S시의 경우 1호선과는 가까울수록 오히려 가격이 소폭 하락하는 현상이 있었으며, 신분당선은 지하철 접근성이 높을수록 매우 가격이 높게 나타났다. 국고채5년평균과 매매가격이 반비례관계였고, M2평잔과 매매가격과 비례관계로 파악이 되었다. 용적률과 총주차대수가 매매가격에 많은 영향을 미쳤으며, 1.5Km 이내의 백화점과 할인마트 존재 여부가 가장 중요한 요인이었다.
