The purpose of this study is to let the entire logistics system be managed in cyberspace by effectively sharing the logistics information between companies involved in the process, changing conventional commerce to electronic commerce. Most of the goods traded through electronic commerce are small goods involving small business transactions. This produces many problems in shipping and delivery and the leads an inefficient logistics system. Another problems is that there is no sharing of information that process the logistics flow and no systematic management of pick-up and delivery information. As a result, rise in logistics cost, longer delivery period and poor service quality are inevitable and these results are becoming an obstacle in the widespread usage of the electronic commerce. Companies that are part of logistics center can cooperate logistics business in Cyber space and share the entire logistics information through the cyber logistics center. This turns out in effective sharing of logistics information, and thus, allows efficient management of logistics, improves logistics service, and reduces logistics cost.

I employ search-and-matching to a multi-country and multi-sector Ricardian model with input-output linkages, trade in intermediate goods, and sectoral heterogeneity, in order to quantify the welfare effects from tariff changes. The paper shows that labor market frictions can be a source of comparative advantage in the sense that better labor market conditions contribute to lower cost in production. Labor market frictions play a critical role in determining the probability of exporting goods to trading partners, and interact with bilateral trade share, price, expenditures, etc. Unemployment and changes in unemployment rates due to tariff reductions contribute welfare changes across countries, implying that welfare effects based on quantitative trade models with full-employment are likely to be biased. I confirm the biased welfare effects by revisiting Caliendo and Parro (2015), who conduct an analysis of the welfare effects from the NAFTA from 1993 to 2005. I show that the welfare gap between theirs and mine has a positive correlation with changes in observed unemployment rates across countries. With the constructed model, I further conduct counterfactual exercises by asking what would happen if China's tariffs remain unchanged from 2006 to 2015. It turns out that there are mild welfare effects to trading partners in the world trading system.

In this paper, I review evidence on changing global specialization in labor-intensive exporting. Production of apparel, footwear, furniture, and related products are how many low-income countries first enter export manufacturing. Just as China's rise as a powerhouse in these goods supplanted a role previously occupied by the East Asian Tigers, the world may again be on the cusp of significant change in where labor-intensive goods are produced. China's prowess in these sectors peaked in the early 2010s; its share in their global exports, while still substantial, is now in decline. Mechanisms through which the global economy may adjust to China's graduation into more technologically sophisticated activities include expanded labor-intensive export production in other emerging economies and labor-saving technological change in products currently heavily reliant on less-educated labor. Available evidence suggests that the first mechanism is operating slowly and the second hardly at all. As a third mechanism, China may in part replace itself by moving labor-heavy factories out of densely populated and expensive coastal cities and into the country's interior. Such a transition, though still in its infancy, would mirror the decentralization of manufacturing production in the U.S. and Europe, which occurred after World War II.

Market share is one of the most important measures in the valuation of prospering firm. It plays a role of composite indicator for the competitiveness of firm. So, the understanding of the underlying process of market share is inevitable factor for the econometricians and the business engager. Lately, the Korean Economy has been placed in the control of IMF. This shock will cause a lot of influence over the domestic economy. The idea that the information about the past shock-response experience will do us good for dealing with this kind of economic shocks is not new. Among numerous markets, we pay attention to the durable goods market, especially automobile market. The automobile market has large repercussion effect over the domestic economy on the issue of both national employment and technology integration. We divided the Korean automobile market into three segments: small, medium, and large-sized car, while each proportion of these segments has been changing slowly. We propose a Bayesian approach to detect and forecast structural changes in time series of the market shares in the domestic automobile market, especially for level shifts and drift changes, and compare the empirical results with other existing approaches.

Purpose - In the digital era, technology advancement enables goods and services to be produced more efficiently but also create economy risk in the global economy including Indonesia. Previous studies stated that the risk can be mitigated through export diversification. This study investigates strategy to expand the markets for existing products and explore the potential market. Research design, data, and methodology - The criteria was followed using a review and considerations combination through the Focus Group Discussion (FGD) to determine the priority product in trading house of Indonesia. This study implemented market share to explore those products' markets and compare it to other ASEAN countries. Results - The Indonesian potential products are T-shirts, singlets and other vests of textile materials, knitted or crocheted (excluding cotton); food preparations; medicaments consisting of mixed or unmixed products for therapeutic or prophylactic purposes; soap in the form of flakes, granules, powder, paste or in aqueous solution; and cocoa powder, not containing added sugar or other sweetening matter. The market analysis also showed that Indonesia still had not optimally accessed yet the largest market in the world for each product. Conclusions - The government should focus more on increasing the competitiveness of those products, particularly in those global marketplaces.

In order to understand the economic damage of economic sanctions on trade between Korea and Russia, a trade structure analysis was conducted through statistics on import and export trade between Korea and Russia. Through the structural analysis of product trade, we tried to accurately analyze the current status of product trade between Korea and Russia. In the trade structure analysis, it was confirmed that the trade in goods between Korea and Russia decreased the most in market share and trade concentration. However, trade specialization, comparative advantage by market, and intra-industry trade index were not significantly affected despite strong economic sanctions. from Russia's point of view Smart measures are needed to address the current situation to avoid a greater economic downturn. The end of the war and the restoration of partnership with other countries are considered the most beneficial solutions for Russia and all countries, but it is difficult to predict how the war will go or what economic situation Russia will be in after the war.

국제무역에 함유된 탄소이력에 대한 연구는 탄소배출의 궁극적인 책임소재에 관한 논란과 연관되어 있다. 지구온난화를 늦추기 위한 범세계적인 노력의 일환으로 수행되는 국가온실가스배출량 집계에 소비에 함유된 탄소배출을 어떤 방식으로든 일부나마 반영하여야 한다는 주장이 제기되고 있다. 본 연구에서는 최근에 발표된 GTAP의 자료기반으로부터 다지역 투입-산출 분석을 위한 각 지역의 투입-산출표를 구성해서 각 지역의 생산과 소비에 함유된 탄소배출량, 따라서 국제무역에 함유된 탄소이력을 측정하였다. 또한 이와 관련된 각 지역의 수출과 수입의 탄소집약도를 분석하고 각 지역의 국민소득이 증가할 때 한국과 세계 전체의 탄소배출량 및 한국의 탄소무역수지에 미치는 효과를 계산하였다. 한국은 에너지 연소로 인한 탄소배출에 관한 한 이산화탄소의 순수입국이나 소비기반 배출량과 생산기반 배출량의 차이가 크지 않은 탄소무역수지 균형에 가까운 것으로 평가되었고 한국의 주요 교역대상국인 선진국들은 탄소무역수지 적자국이며 개발도상국들은 탄소무역수지 흑자국으로 평가되었다.

The concept of wearable computer says to be able to connect to network freely without restrict of place and time through the garment that contain the wire and circuit. Thereby we can realize the ubiquitous circumstances. Wearable computer plays a role of center in controlling the electronic equipments under the ubiquitous circumstances and also it will become the main stream of the future computer development. The current wearable computer displays ugly appearance by attaching the parts of computer on the garment instead of installing them in the box. However, as size of computer components are minimized and it's speed is getting faster, it is certain that wearable computer will evolve as fashionable computer, still retaining garment's original purpose such as fitting and fasion even though the computer is being installed to the clothing. This study reviewed about components, future market share, developed goods, human-being becoming cyborg, application area, restrict and on-going research of wearable computer.
