This paper investigates the effects of TPP on Korean domestic employment. Using data from 1995-2011 obtained from the world input-output database (WIOD) and firm-level data, this paper attempts to identify changes in global value chain (GVC) structures involving Korea and TPP member countries in the Asia-Pacific region. Three stage least squares estimation is employed, and empirical findings show that there exists a statistically positive and significant causal relationship between GVC and domestic manufacturing employment. The positive impacts of TPP on Korean domestic employment suggest that Korea actively encourage TPP negotiation. TPP will bring positive domestic employment effects and opportunities for structural transformation in the manufacturing and services industries in Korea.

Uncertainty and variability in Life Cycle Assessment(LCA) have been significant key issues in LCA methodology with techniques in other research area such as social and political science. Variability is understood as stemming from inherent variations in the real world, while uncertainty comes from inaccurate measurements, lack of data, model assumptions, etc. Related articles in this issues were reviewed for classification, distinguish and elaboration of probabilistic/stochastic health risk analysis application in LCA. Concept of focal zone, streamlining technique, scenario modelling and Monte Carlo/Latin Hypercube risk analysis were applied to the uncertainty/variability analysis of health risk in LCA. These results show that this general framework of multi-disciplinary methodology between probabilistic health risk assessment and LCA was of benefit to decision making process by suppling information about input/output data sensitivity, health effect priority and health risk distribution. There should be further research needs for case study using this methodology.

물이란 지구촌의 약 60억 인구가 삶을 영위할 수 있게 하는 필수적인 요소이면서 지역적 이동성이 제한된 재화라고 할 수 있다. 물 산업의 중요성은 전 세계적으로 증대되고 있으며 그 시장 규모는 2007년의 3,360억 달러에서 2025년에는 약 8,650억 달러까지 커질 전망이다. 국내 물 산업의 규모는 2003년 기준으로 약 11조원으로 추산된다. 하지만본 연구에서 사용된 2000년부터 2008년까지의 산업연관표를 이용한 분석에서 2008년 국내 물 산업의 시장규모는 약 9조 4백억 원으로 추산되었다. 기존 물 산업 규모를 추정한 연구들과 비교해 볼 때, 본 연구를 통해서 도출된 결과가 적게 나타난 것이 사실이다. 또한 재정의된 물 산업의 경제적 파급효과는 가격파급효과만을 생각했을 때 약 0.12%인 것으로 추산되었다. 이는 물 산업 육성정책이 성공적으로 시행된다고 본다면 시장 가격 결정 원리에 의해서 물 가격이 책정되어야 하는데, 물 공급가격이 현실화되어도 국민경제에 미치는 영향은 적을 것임을 나타낸다. 물론 물 산업의 특성상 다양한 이유로의 세제 혜택이 있으나 이는 본 연구의 범위에 포함하지 않았다.

The New Way of Working (NWOW) is changing the world in which we work today. The principles of NWOW are based on freedom of time and place to work, and steering on output (results) instead of input (presence). As NWOW is a relatively new phenomenon, research on the effect of NWOW on knowledge sharing in organizations is scarce. In this research two multiple-case studies were performed to investigate the effect of the New Way of Working on knowledge. In the first study (A) different knowledge sharing scenarios were used at organizations that were in the process of implementing NWOW. This provided the opportunity to compare the sharing of knowledge between 'NWOW workers' and employees that still worked in the traditional way (non-NWOW workers). In total 216 scenario results were evaluated to determine differences in channel choice between the traditional and new work environment. For the second study (B) a Knowledge Sharing Framework was developed, based on the theories of Nonaka and Alavi & Leidner. This framework was used to determine the type of knowledge shared, e.g. tacit or explicit knowledge, in 84 situations. Additionally, to measure the level of NWOW adoption, a NWOW Analysis Monitor was used. The results show that NWOW workers use more different communication channels than traditional workers. When knowledge workers become more mobile, they will exchange knowledge less explicit (codified) and more tacit (personalized), use less face-to-face communication, but more video calls and e-mail. The adoption of the principles of NWOW seems to have a balancing effect on the knowledge that is shared in a tacit and explicit way, which in the view of Scheepers et al. is an effective knowledge sharing strategy. The research results show organizations need to realize that the New World of Working is affecting the way knowledge is shared. Missing out on this development may result in the loss of important knowledge and impact the operation of organizations.

Purpose - This paper investigates the structure of exports across countries in terms of value added. Exports value added is examined under two categories, domestic and overseas. Using a statistical classification method by distance based on these two value added categories, this paper estimates the similarity of exports value added across countries including Korea. Design/methodology - The model of study is to employ a generalized distance function and then derive the Manhattan and Euclidean distances. The paper also performs cluster analysis using the Partitioning Around Medoids (PAM) and hierarchical methods to classify the 44 sample countries considered in this study. Findings - Our main findings are as follows. The 44 countries can be classified under 5 groups by their domestic and overseas value added in exports. Korea has a sandwich global value chains (GVCs) position between Japan, China, and Taiwan in the East Asian region. Originality/value - Existing papers point out the double counting problem of trade statistics as the intermediate goods trade across borders increases. This paper addresses the double counting problem by using the World Input-Output Table. The paper shows the need to explore the similarity of value added in exports structure across countries and investigate the GVCs position and role of each country.

본 논문은 세계 자동차산업을 대상으로 2015년판 OECD-TIVA 자료 분석을 통해 구축된 수출품의 해외조달 부가가치 네트워크 특성을 사회네트워크 기법을 활용하여 분석하였다. 그 연구결과를 요약하면 다음과 같다. 첫째, 1995-2011년 기간 동안에 생산공정 분업은 EU, NAFTA와 같은 역내 경제블록에 한정된 것이 아니라 세계적인 차원으로 심화되었다. 둘째, 수출품의 부가가치 해외조달 네트워크는 위계적이고 공간적으로 집중되고 평균거리가 짧아지는 좁은 세상 네트워크의 특성들을 보여주었다. 셋째, 자동차산업 글로벌 가치사슬에서 주요 공급자는 소수의 국가들에 불과하지만 중간재의 사용자는 다수의 국가들이다. 가장 핵심적인 해외 부가가치의 공급자들인 미국, 독일, 중국 간에 특징적인 차이가 존재한다. 생산공정 분업이 글로벌 수준에서 전개된 것은 사실이지만 그 이면에 중심과 주변, 국내와 외국자본의 이분법의 긴장이 놓여 있다.

Currently, the concern about the environment is the issue all over the world, and in particular, carbon emissions of the power plants will not be able to disregard from the respect of generation cost. This paper proposes DR (demand response) as a method of reducing carbon emissions and therefore, carbon emissions cost. There are a number of studies considering DR, and in this paper, the effect of DR is focused on the side of carbon emission reduction effect considering Time-Of-Use (TOU) program, which is one of the most important economic methods in DSM. Demand-price elasticity matrix is used in this paper to model and analyze DR effect. Carbon emissions is calculated by using the carbon emission coefficient provided by IPCC (Intergovernmental Panel on Climate Change), and generator's input-output characteristic coefficients are also used to estimate carbon emission cost as well as the amount of carbon emissions. Case study is conducted on the RBTS IEEE with six buses. For the TOU program, it is assumed that parameters of time period partition consist of three time periods (peak, flat, off-peak time period).

This paper provides empirical evidences from the Baltic States on the relationship between technology and trades. In this study, regression and correlation analysis were employed an attempt to reveal the relationship between technology index and net-export coefficient, as well as the relationship between technology index and import coefficient. In this research, technology level was measured by technology index, while trades included of domestic and foreign trades; export and import. The data used for this study were collected from world input-output databases of Estonia, Latvia and Lithuania for the period 2000, 2005, 2010, and 2014. The findings remarked that the relationship between technology and domestic trade was positive and statistically significant. The result of the study implies that the higher was the technology index leads to the higher domestic transaction. Furthermore, relationship between technology and net-export was unpredictable. In year 2000, data from Estonia and Latvia showed that the relationship between variables was negative and in other years of the study, the relationship was positive. However, the relationship between variables was not statistically significant. Lastly, the relationship between technology and import was negative and statistically significant. It implies that the higher was technology index, will have a consequence the smaller was import.
