When landowners have private information about land value, compensation based on conservation value at the time of regulatory takings of land is impractical even though it generates an efficient outcome. No compensation rule to a landowner not only yields an inefficient outcome but also provides an ex ante pervasive incentive for the landowner to invest in lowering conservation value. An alternative rule of compensation based on the market value of the land provides ex ante incentives for landowner either to reduce conservation value or to increase it. Under the market value compensation rule, placing the burden of proof on landowner gives higher probability of conservation than placing it on regulator. Whether it is better to allure landowners to conserve by paying compensation with market value and placing the burden of proof on landowner through changes in the regulatory regime however depends on the magnitude of inefficiency, equity consideration and dynamic nature of property rights on environmental goods.

In the paper, the development of high-speed industrial turbo blowers with foil air bearings is presented as a first successful commercialization in the world. Their target market is various from wastewater treatment to cement factory processes which require compressed air ranging between 0.6 and 0.8 bar gauge. Employing the state-of·the-art technology of the high-speed BLDC motors, the bump-type foil air bearings and the high- efficient turbo impellers/diffusers, so much compact, efficient and silent blower machines of a single stage are now available in the market, aiming to replace the existing inefficient, bulky and noisy ones, such as roots blowers. The first production lines are established fur 25,75 and 150 hp class blowers. Rotational speeds from about 20,000 to 80,000 rpm are realized directly from the high-speed BLDC motors without any gear boxes, and no lubrication oil is required. A brief introduction of design, manufacture and test results is presented fur mechanical, electrical and aerodynamic performance.

Recently, it is recognized as a high-cost and inefficient logistics system that increases traffic congestion and environmental problems due to an increase in traffic volume due to the activation of the online market. In order to solve inefficient problems such as unavoidable traffic congestion and environmental problems caused by the increase in traffic volume, it is necessary to develop a freight transport system technology using the existing urban railway infrastructure and freight-only urban railway. The urban subway logistics system is a logistics system that requires a combination of various technologies to solve the nationwide demand for urban logistics and road traffic problems. This paper recognized the existing traffic congestion and environmental pollution of road traffic as problems, and supplemented the contact point requirements presented above by identifying the sub-systems constituting the target system and supplementary points for each part-level contact point. In this study, as a complex system operated for one purpose by grafting various technologies, a plan is required to secure the reliability and safety of operation from various viewpoints. The results of this study can contribute to the initial configuration and basic data to solve the interface bottleneck of the urban subway logistics system to be promoted in the future.

디지털 기술에 기반한 다양한 미디어가 출시되면서 한정된 재원을 사이에 두고 경쟁이 심화되고 있다. 특히 광고재원에 대한 의존도가 높은 우리나라는 광고시장 확대가 미디어 다양성 유지에 필수적인 요소이다. 정부는 PPL 허용 등 광고시장 확대를 위한 다양한 정책을 시도하였으나 역부족이다. 본 논문에서는 높은 대중 영향력에도 불구하고 뉴미디어의 출현으로 광고매출이 위축되고 있는 TV를 대상으로 광고시장 결정요인을 분석하였다. OECD 28개 국가의 미시적 데이터를 이용하여 횡단면 분석을 수행한 결과, 서비스 산업의 비중이 낮고, 실업률이 높으며, 조세부담률이 낮을수록 광고시장이 빠르게 성장함을 확인하였다. 반면, 높은 1인당 GDP는 광고시장의 성장속도에 부(-)의 영향을 미쳤다. 그러므로 향후 우리나라 광고시장은 성장세가 낮아지고, TV 광고 비중도 낮아질 것으로 전망되었다. 그리고 이를 토대로 직접납부 재원의 증대와 비효율적인 미디어 기업의 퇴출구도 확립 등의 대안을 주장하였다.

The United States has a unique health care system, which is unlikely any other health care systems in the world. The major part of basic functional components of the system -financing, insurance, delivery, and payment- is in private hands. A market-oriented economy invites the participation of numerous private entities that are interested in carrying out the key functions of health systems. Due to this central feature, U.S.health care is not delivered through a network of interrelated components designed to work together coherently. For lack of standardization, the various components of the system fit together only loosely. The involvement of numerous players in the key functions leads to duplication, overlap, inadequacy, inconsistency, and waste, which add to the complexity and also make the system inefficient. Hence, cost containment remains an elusive goals. Moreover, the system falls short of delivering equitable services to all americans, though consumption of health care services is the largest in the world. On the other hand, United States leads the world in the latest and the best in medical technology, medical training, and research. It offers some of the most sophisticated institutions, products, and processes of health care delivery. This article discuss the characteristic features of the U.S. health care system. and its performance, trying to seek its implication on Korean health care system.

주파수와 같이 매우 희소한 경제적 자원을 배분하는 경우 경매는 배분적 외부성으로 인하여 비효율적 결과를 낳을 수 있다. 경매수입이 아닌 사회후생을 기준으로 하면, 경매를 통한 배분은 경매참여자가 2인일 때에도 비효율적일 수 있다. 이는 2위 기업이 주파수를 더 효율적으로 활용할 수 있다 하더라도 이를 통해 얻는 이익은 크지 않은 반면에 선도기업이 시장을 잠식당함으로써 입는 손실이 클 때 발생한다. 2-경기자 호텔링 모형을 사용하여 분석한 결과, 2위 기업의 입찰가에 어떠한 승수를 곱함으로써 2위 기업을 경매에서 유리하게 만들 경우 경매를 통한 배분 결과가 파레토 개선된다. 승수는 시장점유율을 바탕으로 구할 수 있으며 시장점유율 격차가 클수록 높다.

This study examines whether the adoption of International Financial Reporting Standards (IFRS) has increased financial statement comparability among firms and reduced undervaluation of Korean firms in the capital market by enhancing financial statement comparability. The so-called Korea Discount, which indicates an inefficient allocation of capital, has been attributed to lack of transparency and comparability of accounting information. Therefore, an efficient distribution of capital in the market was intended when IFRS was first adopted in Korea, but such progress is based on a premise of enhancement in Korean firms' accounting information comparability. This study conducts empirical analysis by using a comparability measure by De Franco et al. (2011). More specifically, it analyzes differences among comparability of domestic firms following IFRS adoption, with firms in the EU, which adopted IFRS in 2005, and with firms in the U.S., China and Japan that do not follow IFRS. The analysis of changes in domestic firms' comparability finds that their comparability improved following IFRS adoption. Meanwhile, the examination of cross-national differences in comparability demonstrates that, although there has been no significant change in comparability with firms in the U.S. and the EU across Korean industry since IFRS adoption, comparability with China has decreased while that with Japan improved.

In 2018, 647 thousand tons of eggs were produced and consumed. However, the issue of pesticides used for egg in 2017 made Korean consumers worry about the food safety of eggs, and the volume of egg consumption decreased. The Korean egg industry also has another problem due to an unclear and inefficient marketing structure at the farm level. This marketing situation of eggs at the farm level in Korea needs a large-scale restructuring of the market structure, including introducing an EPC (egg processing center). Especially, the introduction of an EPC has been discussed by government officers and specialists, but the social benefit of an EPC, which will be the driving point for approving an EPC, has not been measured yet. The purpose of this study was to measure the effect of introducing an EPC in Korea. Through an analysis using EDM (equilibrium displacement model), a few findings are presented. First, the introduction of an EPC may increase the transparency of price discovery and decrease the transaction cost. And thus, it results in a higher producer price, lower consumer price, and larger quantity at market equilibrium. Second, an EPC will improve the level of food safety of eggs, which can increase the satisfaction of domestic producers and consumers. Third, the introduction of an EPC may create new consumption of eggs. Based on these three effects, the new social benefits in monetary terms from the introduction of an EPC in Korea could be 23.9 - 35.2 billion won.
