40 ABSTRACT The Korean government has recently decided to dramatically expand renewable energy technologies (RETs) while reducing the portion of nuclear and/or coal power generations. The large deployment of RETs could possibly hurt the power system reliability because of the unreliability of RETs. This paper proposes a model for analyzing the effects of unreliable RETs on the reliability of power supply and the level of reasonable reserve margin. Numerical analysis provides some interesting findings. First, the 7 th basic power supply plan (the 7 th basic plan for long-term electricity supply and demand) could fail to meet the target level of power system reliability after In addition, the power system reliability could possibly worsen in the 8 th basic power supply plan, which reduces the portion of nuclear and coal power generation and increases RETs, even though the 8 th basic power supply plan sets the installed reserve and capability margin as 20% and 18% respectively, which are higher than those in the 7 th basic power supply plan, 16% and 12% respectively. Key Words:Power generation mix, Renewable energy, Supply uncertainty, Power system reliability

70 ABSTRACT In this paper, we estimate the determinants of the demand function for electricity by FD GMM method based on panel data of 16 regions during the results of the study are as follows. 1) The results of a partial adjustment model showed better results than these of ARDL model in terms of statistical significance and economical meaningness; 2) the elasticities of price and income were negative(-) and positive(+) and the long run elasticities were more elastic than the short run; 3) the elasticities of cooling degree days and aging population ratio were positive(+) and negative(-); 4) there was a rebound effect that the effect of economic growth dominates the effect of energy efficiency improvement over time; 5) the government policy for electricity needs to consider the increased income elasticity that dominates the increased price elasticity. Key words : Electric demand, FD GMM, Patial adjustment model, Elasticity, Rebound effect 65

99 ABSTRACT This paper tests Environmental Kuznets Curve Hypothesis using time series data of Korea in the time period between the years 1971 and 2014, and analyzes the determinants of CO 2 emissions. For this purpose, we consider GDP per capita, the portion of renewable energy relative to the nation s power source, final energy consumption per capita, and cooling and heating degree day as the explanatory variables. And, considering nonstationarity of the time series, we analyze the relationship between CO 2 emissions and explanatory variables in the framework of a cointegration model and an error correction model. The test results show that there exists a statistically significant positive relation among GDP, cooling and heating degree day, final energy consumption and CO 2 emissions, and a statistically significant negative relation among GDP square, the portion of renewable energy and CO 2 emissions. That is, the results ascertain the existence of Environment Kuznets Curve in Korea and the significancy of temperature effects on CO 2 emissions. Key Words : CO 2 emission, Environmental Kuznets Curve Hypothesis, Temperature Effects, Cointegration, Error Correction Model

134 ABSTRACT This paper investigates aging index that best describes household electricity consumption in Korea, and then predicts household electricity consumption volatility according to aging. The empirical analysis of panel data shows two important results. First, not the population ratio above age 65 but aging index and median age are more related to household electricity consumption. Second, if a society becomes an aging society, income elasticity will be more inelastic. Contrary to income elasticity, price elasticity of household electricity change more elastically when aging index increases. Therefore, it implies that not only price policy but also efficiency improvement policy should be implemented for stabilization of electricity consumption volatility necessary to renewable energy supply expansion. Key Words : Residential Electricity Consumption, Aging, Model Averaging, Threshold Panel Regression

156 ABSTRACT This Study explores the long run equilibrium and market integration of international coal, oil and natural gas prices using weekly data from January 2004 to September Our test results from error correction model yield increased estimates for the long run equilibrium and the degree of market integration, when compared to previous literature. These higher parameters are likely to be driven by the wide spread of shale oil and shale gas from These empirical results imply that energy prices of primary fuels are adjusted more quickly to external shocks after Our results are also expected to be informative when energy firms purchase primary fuels in the spot market or using long term agreements. Key Words : international energy p rices, Shale gas, error correction model

182 ABSRACT This study analyzed the dynamic relationship of international oil market integration. Considering the possibility of structural change, unit root test and cointegration analysis were carried out. The structural change dummy variable based on the endogenously determined break-point is included for the whole period. Cointegration and Granger causality analysis between the international oil prices was conducted for the periods before and after the break-point. As a result, the prices of WTI, Dubai and Brent showed a random walking and a co-integration relation, and the international oil market was integrated. However, the long-run equilibrium relationship and the causal relationship between international crude oil prices were different in sub-periods. The prices of WTI, Dubai and Brent before the structural change showed a significant influence on the mutual prediction with cointegration relaton. However, after the structural change, WTI, Dubai, and Brent prices did not have a long-run relation as well as causality. The integration of the international crude oil market can be seen as a dynamic phenomenon depending on structural changes and analysis periods.

212 ABSTRACT This study investigates volatility spillover between crude oil futures and East Asian stock markets using the AR(1)-FIAPARCH-DCC model during period Empirical results of this study were summarized as follows. First, this study finds the evidence of long memory and asymmetry in volatility between crude oil futures and east Asian stock markets. Second, conditional correlations show that the pair of WTIF-China has the highest correlation and the pair of WTIF-Japan has the lowest correlation. Third, conditional correlations between crude oil futures and East Asian stock markets increase after the 2008 global financial crisis. Fourth, the average hedge ratio is highest for pair of WTIF-Hong Kong, while that of WTIF-Japan is the lowest, this result shows that a pair of WTIF-Japan offers the most efficient hedge ratio. Lastly, time-varing hedge ratios increase rapidly as do structural changes such as the financial crisis. Key Words : Long Memory, Asymmetry, Volatility Spillover, Hedging Ratio, Crude Oil Futures

245 ABSTRACT This Paper explored whether the price pattern of gasoline prices in Korea follows the Edgeworth price cycle. The Edgeworth price cycle represents the pattern of price change in the Markov Nash equilibrium of the dynamic price competition (Maskin and Tirole, 1988). Prices in the cycle decline gradually but increases very rapidly. When the movements of gasoline retail prices in Seoul were investigated, it was found that the frequency of price change is higher in the periods of price decline than the those of price increase but the magnitude of the change was greater during the price hikes. The asymmetric price changes coincides with the price behaviors predicted by the Edgeworth price cycle. A policy implication is that the asymmetric behaviors of prices in price upturns and downturns do not necessarily results from collusion among competitors but they can be the outcome of price cutting competition in the process of long-run profit maximization. Key Words: Edgeworth Price Cycle, Asymmetric Price Response, Gasoline Prices

269 This paper analyzes a factor decomposition of GHG emissions in domestic electricity generations sector using LMDI (Log Mean Divisia Index) method. These factors are divided into six factors: population effect, electricity intensity effect, electricity generation mix effect (generation mix effect by total fossil fuel generation ratio), power generation mix effect (generation mix effect among fossil fuels), electricity generation efficiency effect, and emission factor effect. The analysis period covers the last 6 years from 2010 to The results show that the power intensity effect is the biggest factor in the increase of GHG emissions of domestic electricity generation sector, followed by the population effect. The other factors influenced greenhouse gas reduction in the order of power generation efficiency effect, power generation mix effect, and power generation mix effect. These differences mainly result from the combination of emission trading system, RPS, greenhouse gas and energy target management system. In particular, the effect of temporary suspension of nuclear power plants was a major factor in the change in Key Words : LMDI, Electricity Generation, GHG emissions, Factor Decomposition

291 ABSTRACT The 8th electricity supply basic plan adds significances on environmental protection and public safety to the 7 th planning, which aimed to achieve reliability and efficiency in generation mix. According to the new plan, nuclear and coal-fired power plants are planned to be phased out steadily, while renewable energy and LNG power plants are to enter to the system. Benefits from projected LNG power plants would include economic impacts from constructing and operating new LNG-powered generating stations. This research estimates induced impacts by constructing and operating a 900 MW LNG with the Input-Output Table 2010 benchmark. Construction is estimated to give the production induced coefficient of 2.258, value-added induced coefficient of 0.684, employment induced coefficients of 6.2people/ mil.won. Operations is estimated to result in the production induction coefficient of 1.176, value-added induction coefficient of 0.554, employment induction coefficients of 1.1 people/mil. Won. Comparing to previous studies, induced impacts by increasing LNG power generations are estimated to be equal or greater those induced by renewable energy. Key Words : LNG Power Plant, Induced Analysis, Input-Output Table
