In this paper, we present a nonrenewable resource model including environmental pollution stock as a state variable to analyze the dynamic structure of environmental tax. Based on the optimality conditions of our model, we showed that the optimal time path of the shadow cost for environmental pollution stock is the same as that of the costate variable for environmental pollution stock. We did this by applying the theorem, Continuous Dependence on Initial Conditions (Coddington and Levinston, 1985, pp. 22∼27), to the optimal control problem. Thus, this result provides a theoretical basis to determine the magnitude of environmental tax to be imposed over time. In addition, we also identified that the costate variable for environmental pollution stock is solely due to the disutility effect.

This paper summarizes the results of a study that assess how a demand side management (DSM) system addresses key economic and environmental challenges facing in the Korean natural gas sector considering; ·high discrepancies of seasonal consumption volume and of load factor in unmatured domestic LNG market, ·unfavorable and volatile international LNG market, imposing with the contestable "take-or-pay" contract terms, ·low profile of LNG and existence of market barriers against an optimal fuel mix status in the industrial energy sector. A particular focus of this study is to establish an `extended` DSM system in the unmatured gas market, especially in industry sector, that could play a key role to assure an optimum fuel mix scheme. Under the concept of `extended` DSM, a system dynamics modeling approach has been introduced to explore the option to maximize economic benefits in terms of the national energy system optimization, entailing different ways of commitments accounting for different DSM measures and time delay scenarios. The study concludes that policy options exist that can reduce inefficiencies in gas industry and end-use system at no net costs to national economy. The most scenarios find that, by the year 2015, it is possible to develop a substantial potential of increased industrial gas end-uses under more reliable and stable load patterns. Assessment of sensitivity analysis suggests that time delay factor, in formulating DSM scenarios, plays a key role to overcome various market barriers in domestic LNG market and provides a strong justification for the policy portfolios `just in time` (time accurateness), which eventually contribute to establish an optimum fuel mix strategy. The study indicates also the needs of advanced studies based on SD approach to articulate uncertainty in unmatured energy market analysis, including gas.

This paper tries to analyze the efficiency structure and regulatory effects in electric power industry by using total factor productivity and indices based on cost function method. This paper performed an empirical analysis on the efficiency improvement and optimal scale taking the cost aspect in electricity industry into account. By expanding the cost structure framework, this paper proposes the analytical method regarding the needs of technology regulation and presents the empirical results which can be verified. Hence, this work can play a key role in decision-making of the national power development and regulatory policy. The empirical result indicates that the electricity industry in Korea has been in the state of economies of scale until 1980s, However, due to sustained growth of power generation, economies of scale declined and subsided after 1980s and then diseconomies of scale is shown recent years. The analysis on the effect of technology regulation shows the national large-scale base-load power plant development-oriented policy until so far contributed substantial cost effect to the electricity industry. The empirical result indicates that the reserve requirement as one of means of technology regulation policy did not contribute to the economies of scale but positive effect on the total factor productivity in Korea.

Based on the hedonic pricing method, this paper investigates the effect of air quality on the apartment price in Seoul. The empirical results show that both the structural variables such as years of construction, heating system, and size of apartment complex and accessability variables such as distances to subway station and parks provide statistically significant effects on the price of apartment, Especially, the dendity of sulfurous acid gas (SO_2) and ozone (O_3) in the air, indicating air quality, negatively affect the price of apartment, This implies that as the condition of air quality to become worse, apartment price decreases, Therefore, when the degree of aversion of apartment residents against the air pollution affects the formation of apartment`s market price, the MWPT (Marginal Willingness to Pay) in order to improve the air quality 10% has been estimated as 36,000 ∼ 39,000Won per month.

This paper explores the impact of public financing for recycling firms on output, using a specific case study of Korea. To this end, we employ a production function approach and apply generalized method of moment estimation technique. The results show that the impact appears to be not only positive but also statistically significant, and more interestingly the estimate for financed capital is numerically larger than that for non-financed capital.

This Paper investigates imperfect competition and economy of scale on Korean energy markets based on computable general equilibrium model. Some industries like energy sector have exhibited that their economies have strong economies of scale and imperfect competition. Thus these industrial organization facts should be incorporated into CGE model. In our model, non-competitive markets are adopted and compare these results with convention perfect competition model.

Approximating bottled water consumption distribution is complicated by zero observations in the sample. To deal with the zero observations, a mixture model of bottled water consumption distributions is proposed and applied to allow a point mass at zero. The bottled water consumption distribution is specified as a mixture of two distributions, one with a point mass at zero and the other with full support on the positive half of the real line. The model is empirically verified for household bottled water consumption survey data. The mixture model can easily capture the common bimodality feature of the bottled water consumption distribution. In addition, when covariates were added to the model, it was found that the probability that a household has non-consumption significantly varies with some variables.
