  • Amid the recent intensification of climate change, the decline of subalpine coniferous species is evident. Accordingly, the Korea Forest Service is conducting research to establish conservation measures, identify the causes of the decline of subalpine coniferous species, and establish conservation strategies for seven species of conifers in the alpine region. This study used an economic value evaluation method to present objective data to inform the need for and value of conservation of endangered coniferous species through the recognition of endangered coniferous species and evaluation of conservation value among coniferous species conservation strategies in endangered alpine areas. A contingent valuation method was applied. As a result, the estimated conservation value per household of endangered alpine coniferous species was 49,181 won.

  • 경제가 고도로 성장하던 단계에서는 기업은 사업규모도 크지 않고, 경쟁환경도 치열하지 않았을 뿐 아니라 내·외부적인 환경도 안정적이기 때문에 양적 확대에만 집중하더라도 그것이 기업가치를 크게 하는 역할을 할 수 있었다. 그러나 내·외부적인 무수한 환경변화와 경쟁격화로 인하여 수익성의 악화가 반복되는 현실에서는 종전과 같은 경영사고나 전략으로는 새로운 환경에서 살아남을 수 없을 것이다. 따라서 본 논문은 기업들의 환경변화에 따른 대처능력과 의사결정을 원활히 하기 위해 기존의 단순 수치의 변환에 의해서 결과를 도출하는 회계 시뮬레이션에서 벗어나 회귀분석과 신뢰구간을 사용하여 기업의 의사결정에 있어서 보다 기업의 현실에 근접한 데이터를 추출하여 의사결정의 원활화를 도모하고자 하였으며 최종 시뮬레이션 결과를 EVA 에 둠으로써 기업의 수익성, 자본효율도 등의 기업가치를 여러 방면으로 추정할 수 있도록 하였다.

  • 본 연구의 분석목표는 순요소증가형 CES 생산함수를 실증적으로 추정함으로써 한국 제조업부문의 기술변화의 유형을 규명하고 성장 ${\cdot}$ 고용 ${\cdot}$ 분배에 대한 기술진보의 파급효과를 분석하는 것이다. 이 분석결과를 토대로 하여, 본 연구는 성장 ${\cdot}$ 고용 ${\cdot}$ 분배를 동시적으로 추구할 수 있는 정책방향을 기술경제 패러다임의 시각에서 제시하였다. 본 연구의 실증적 분석결과는 다음과 같이 요약할 수 있다 : 한국 제조업부문의 기술변화의 유형은 Hicks형 비(非)중립적인 자본사용적(B(t)>0) 즉 노동절약적 기술진보인 것으로 추정되었다. 이 결과, 잠재적 고용수준은 감소될 수밖에 없었다. 또한, Hicks형 중립적 기술진보를 나타내는 총요소생산성 증가율(${\gamma}$)은 감소하였던 반면에, 비(非)중립적 기술진보를 나타내는 요소간 대체탄력도(${\sigma}$)와 자본집약도(${\delta}$)는 증가하였다. 이에 따라 노동(L)이 자본(K)으로 광범위하게 대체되었을 뿐만 아니라, 자본투입(K)이 노동투입(L)보다 상대적으로 더 빠르게 증가 (K/K > L/L 즉 k/k > 0)되었다. 이 결과, 소득분배구조가 악화 (S/S< 0)된 것으로 추정되었다. 그러므로, 오늘날 경제성장의 한계 봉착, 대량실업의 폭발, 계층간 갈등의 심화를 초래한 요인은, 성장 ${\cdot}$ 고용 ${\cdot}$ 분배를 동시적으로 추구하는 산업 ${\cdot}$ 기술경제정책을 일관성있게, 또한 과감히 추진하지 않았던 결과, 노동사용적 중소기업의 몰락, 노동의 생산효율성 증진을 위한 인적자본 투자의 미흡, 자본의 생산효율성 증진을 위한 자본절약적 기술진보의 저조, 총요소 생산성 증가의 부진, 만성적인 인플레이션에 의한 실질 임금수준의 하락 및 실물 자산가치의 상승 등이라고 말할 수 있다. 따라서 성장 ${\cdot}$ 고용 ${\cdot}$ 분배의 조화는 바로 노동효율 증가형 기순혁신이며, 이를 위한 인적자본에의 투자라고 말할 수 있다. 본 연구가 기술경제 패러다임(techno-economic paradigm)의 시각에서 제시하는 한국경제의 성장 ${\cdot}$ 고용 ${\cdot}$ 분배를 위한 정책방향은 다음과 같은 동태적발전과정으로 요약할 수 있다 : 기초과학연구능력 확충 ${\rightarrow}$ 소화 ${\cdot}$ 흡수 ${\cdot}$ 개량 ${\rightarrow}$ 토착화 능력의 배양 ${\rightarrow}$ 자체기술개발, 선진기술 도입, 산업간 및 산업내 기술확산, 국제기술협력 ${\rightarrow}$ 기술혁신의 촉진 ${\rightarrow}$ 총요소생산성과 기업경쟁력(자원 및 역량, 프로세스 경쟁력, 품질경쟁력, 시장경쟁력, 고객성과, 시장성과, 재무성과)의 제고 ${\rightarrow}$ 가격경쟁력(임금, 금리, 물류비용, 환율 등)과 비(非)가격경쟁력(디자인, 에프터서비스, 품질, 운송 등)의 제고 ${\rightarrow}$ 국가경쟁력의 제고 ${\rightarrow}$ 국제수지 흑자 ${\rightarrow}$ 성장 ${\rightarrow}$ 물가 및 고용 안정 ${\rightarrow}$ 분배 ${\rightarrow}$ 최대다수의 최대행복이다.

  • This paper attempts to quantitatively assess the conservation value of Ellobium chinense (EC), which belongs to the endangered marine species designated by Ministry of Oceans and Fisheries. To this end, we apply the contingent valuation (CV) method, an economic technique of valuing a non-market goods such as EC. A national survey of randomly selected 1,000 households was administered in order to derive the public's willingness to pay (WTP) for conserving EC. One-and-one-half-bound model was adopted to elicit the WTP responses and a spike model was employed to deal with the zero WTP responses. The results show that the conservation value of EC is estimated to be 2,346 won per household per year that is statistically significant at the 1% level. Expanding the value to the national population gives us an annual value of 43.8 billion won. We can judge that the Korean people are willing to pay a significant amount to conserve EC.

  • This study tries to quantify the regional NIMBY costs to nuclear power plants. NIMBY costs are estimated as willingness to pays for avoiding nuclear power plants near residential areas through the contingent valuation method(CVM). In the study, it was assumed that the nuclear power plants were newly constructed around the residences. The result of 600 respondents living within a radius of 30 km of nuclear power plants compared to the result of 600 respondents living in the metropolitan area, which revealed that there were significant NIMBY costs to the construction of nuclear power plants in all residences. By region, the willingness to pay in the metropolitan area was greater than that in the nuclear power areas. This study focuses on NIMBY to nuclear power plants from a regional point of view, which can provide important information in establishing prudent and sound nuclear power policies.

  • In this paper, we estimate a time series model of energy demand in the industrial sector with an asymmetric response to energy prices. Including the asymmetric response to energy prices in the model strengthens robustness of the cointegration relationship and reduces the variation of the estimated coefficients across the estimating methods. We find that rising energy prices have a larger impact on energy demand than falling energy prices, with the largest impact occurring when energy prices rise to new highs. The estimation results are partially improved when using gross output rather than value added as a measure of production. Using single equation methods to estimate the asymmetric response model, the elasticity of gross output ranged from 1.05 to 1.09 and the elasticity of price-rise ranged from -0.48 to -0.56, which is similar to the results of international studies.

  • The government has implemented the projects of restoring the ecological integrity of streams to improve its water quality and provide resting places with local residents. Because the projects require huge public investments, their economic feasibility should be investigated through ex-post examination of their benefits. This study attempts to analyze the economic feasibility of restoring the ecological integrity using specific cases of Namyang stream in Hwaseong, Gyeonggi and Yugu stream in Gongju, Chungnam. The contingent valuation (CV) method is employed to measure the benefits. To this end, a professional polling firm conducted two CV surveys of 210 and 209 households for Hwaseong and Gongju, respectively. The willingness to pay (WTP) model used in the study is based on utility difference approach and the single-bounded dichotomous choice spike model. The results reveal that the WTP for restoring ecological integrity of the Namyang and Yugu streams are estimated to be 3,140 and 10,121 won per household per year. Interestingly, the latter is about three times greater than the former. The quantitative information can be used in economic feasibility analysis of the projects of restoring the ecological integrity of the Namyang and Yugu streams.

  • Electricity is a basis for human existence. This paper attempts to analyze the households' willingness to pay (WTP) for the residential electricity use. The WTP for the residential electricity use can be defined as the sum of actual price of and additional WTP for it. The former is easily observed in the market, but the second is not observed and thus should be obtained through a WTP survey of households. To this end, this study conducted a survey of randomly selected 1,000 households in Korea in November 2010. The results indicate that the mean additional WTP for the residential electricity use was estimated to be KRW 11.24 per kWh. Given that the average price of residential electricity was KRW 98.07 per kWh at the time of the survey, the economic benefit from the residential electricity use was computed as KRW 109.31 per kWh. This information can be compared with the cost involved in the supply of one kWh of residential electricity.
