This paper investigates the relationship between the minimum wage and firm's export behavior by using firm-level data of Vietnamese manufacturing enterprises over the period 2010 through 2015. In this regard, I apply the logistic regression model for the probability of exporting and the differences-in-differences analysis to the data, and find that raising minimum wage standards drive no new exporters but a rise in a firm's export sales. Less productive and more labor-intensive firms raise their amount of exports in response to increasing minimum wage levels. Being exposed to increasing minimum wage levels makes a firm under-perform in terms of export sales compared to non-exposed firms.

A five-year field monitoring was conducted to monitor characteristics of suspended solid (SS) export from paddy fields. The observed EMCs of SS ranged 1.2~517 mg/L (avg. 52.1 mg/L) during storm period. The concentration of SS during non-storm period were 1.1~349.5 mg/L (avg. 36.1 mg/L). Monthly load of SS was high during summer when rainfall amount was high. The load was higher than that of May when tillage effect is expected. There was no significant relationship between SS EMCs and rainfall or drainage amount. However, effects of rainfall and drainage were found to be significant for event load of SS. But, there was no apparent relationship between rainfall amount of cropping period and load of SS for that period. The observed SS load was 164.8~456.0 kg/ha (avg. 301.2 kg/ha) and mostly occurred during storm period. This study results also suggested that SS load estimation by USLE equation for paddy field could be overestimated, if not carefully handled. Monitoring studies for various climate, soil, and agricultural management are required to get better scope of SS export from paddy fields.

The amount of export of paprika has been increased rapidly in recent years. Therefore, its cultivation area has greatly increased in Korea according to current consumer's attraction. Moreover, it becomes one of the major exporting products while it recorded 53 million dollars, in 2009 resulting in 40% of the total vegetables export. Most of the products are exported to Japan, but it is necessary to prolong the quality preservation periods to export paprika to nations like U.S.A. or EU. However, to encourage an export to many countries, washing and disinfection became more important to deal with longer transportation and medical inspection. The non-chemical use is very important due to stronger regulation of safety to agricultural production. Accordingly, this study was performed to determine the optimum conditions and develop a prototype washing machine, hot water washing of paprika. The results were as follows : The working performance of the prototype was 938 kg/hr, and which was 1.5 times higher than the conventional air gun type washing machine. The operation cost of prototype was 30 won/kg, and 56% of the cost was reduced when compared with air gun type washing machine.

The Association of Southeast Asian Nations(ASEAN) has been the most essential organization in Asia. In spite of the world economic crisis, Southeast Asian countries have shown fast economic growth since 2000, and they have been actively expanding investments and trades especially with major countries. Research on competitiveness in ASEAN market has spawned an increasingly large literature, but empirical research on the determinants of Korea's export to ASEAN is limited. The purpose of this study is to draw out the determinant of Korean fisheries export to ASEAN by carrying out a panel analysis. For achieving such a purpose, pooled OLS, Hausman Test, Fixed Effect, Random Effect are performed. The last 20 years' data over the period of 1995 to 2014 concentrated on the ASEAN 6 countries such as Indonesia, Malaysia, Philippine, Singapore, Thailand, Vietnam is used in this study. Amount of aquatic products export to ASEAN is used as the dependent variable; real exchange rate, real GDP, relative price level and GDP per capita are used as the explanatory variables and FTA as dummy variable. Empirical results show that fixed-effect analysis is the best model among all the models. As the fixed effect model shows, real exchange rate, real GDP, GDP per capita and dummy variable(FTA) play positive and statistically significant roles in fisheries export to ASEAN, while price variable plays a negative and statistically significant role to the dependent variable.

자동차산업에 있어서 FTA는 매우 중요한 무역정책 중 하나이다. 자동차산업이 국가의 고용과 생산에서 차지하는 비중이 큰 만큼 대부분의 국가들이 취하는 보호무역조치가 자동차산업을 타깃으로 하는 사례가 많기 때문이다. 이러한 관점에서 한 콜롬비아 FTA를 비롯해 한 페루 FTA와 한 칠레 FTA 등 대(對) 중남미 FTA 전략은 우리나라 자동차산업 발전에 시사 하는 바가 매우 크다 할 수 있다. 본 논문은 한 칠레 FTA의 체결 전후의 자동차 수출 영향요인 변화 분석을 통해 중남미 자동차 수출 전망을 예측하고 대응 방안을 모색하는 데 목적이 있다. 연구결과 '환율', 'GDP', '유가' 등 요인 변수 중 'GDP'가 FTA 이전과 이후 모두 수출 성과와 강한 상관관계를 보였으며, 회귀분석에서도 'GDP'만이 수출성과에 영향을 미치며, 특히 FTA 발효 이후 영향력이 더욱 높아진 것으로 나타났다. 이는 중남미 자동차 수출에 FTA 효과도 중요하지만 현지 국의 경제상황과 강력히 연동하고 있다는 점을 시사하고 있어 현지 생산 체제 구축 등 이에 대한 대응 방안 모색이 요구된다.

Purpose - Korean exports account for a vast proportion of Korean GDP, and large volumes of Korean products are sold in the United States. Identifying and characterizing actual and potential product hazards related to Korean products is critical to safeguard Korean export trade, as severe quality issues can impair Korea's reputation and reduce global consumer confidence in Korean products. In this study, we develop country-of-origin-based product risk analysis methods for social media with a specific focus on Korean-labeled products, for the purpose of safeguarding Korean export trade. Design/methodology - We employed two social media datasets containing consumer-generated product reviews. Sentiment analysis is a popular text mining technique used to quantify the type and amount of emotion that is expressed in the text. It is a useful tool for gathering customer opinions regarding products. Findings - We document and discuss the specific potential risks found in Korean-labeled products and explain their implications for safeguarding Korean export trade. Finally, we analyze the false positive matches that arise from the established dictionaries that were used for risk discovery and utilize these classification errors to suggest opportunities for the future refinement of the associated automated text analytic methods. Originality/value - Various studies have used online feedback from social media to analyze product defects. However, none of them links their findings to trade promotion and the protection of a specific country's exports. Therefore, it is important to fill this research gap, which could help to safeguard export trade in Korea.

본고는 2003~2013년 기간 동안 62개 국가의 양자 무역자료를 이용하여 양자 간의 수출과 수입에 FTA와 FTA의 파급효과가 미치는 영향을 분석하였다. 이를 분석하기 위해 본고에서는 1) FTA더미변수와 2) FTA더미변수를 이용한 가중평균수출입 규모를 FTA의 파급효과 변수로 구축하였으며, GMM, 패널 고정효과 및 확률효과, 그리고 PPML 추정방법을 이용하였다. 분석결과, FTA변수는 양자 간의 수출과 수입에 양(+)의 관계를 보여, 양자 간의 FTA가 무역창출 및 무역전환 효과에 의해 수출입을 증가시키는 것으로 나타났다. FTA의 파급효과를 나타내는 FTA 가중평균수출입 규모 변수도 모든 분석모형에서 양(+)의 값을 갖는 것으로 분석되어, 주변국 또는 제3국들의 다양한 FTA 체결은 양자 간의 무역규모를 증가시키는 것으로 나타났다. 따라서 본고는 무역을 증가시키기 위해서는 다양한 FTA를 체결한 국가와의 무역을 하는 것이 바람직하며, 향후 FTA의 분석은 기존의 2개국 모형에서 3개국 모형 분석으로 확대될 필요성이 있다는 시사점을 제시하였다.

Abalone aquaculture has developed very rapidly in Korea. Until the mid 1990s it has annually produced about 100 tons. Since then the yield has increased to about 9,000 tons in 2012. The amount accounts for 20% of the global abalone yield. About 86% of produced abalone is consumed domestically and the rest is exported. 100 tons for export seemed as an unattainable goal back in 2003. However, the export rose up to 1,333 tons in 2012. Despite its rapid growth, Korean abalone industry is faced with some problems. The first is the slowdown of yield increase rates. Abalone production increased by 50~60% until the mid 2000. However, the rate continued to drop to below 10%. Reasons behind the slow increase are deteriorating aquaculture grounds and worsening market problems. Constant aquaculture aggravated productivity and overcrowded facilities at a limited space made matters worse. Moreover, abalone export has stalled and so did domestic consumption. In the meantime, rising mortality of young abalone has lowered productivity at abalone breeding places. The mortality rates of abalone remained below 5% in the early 2000s but rose to 30~40% these days. This translates into rising abalone prices. The market problems imply stagnant or shrinking export as well as domestic consumption. The export increase rates took a nosedive from 200 to below 50 between the early 2000s and the late 2000s. Moreover, the increase rates of domestic consumption have become remarkably sluggish. According to, it stood at 50~60% in the mid 2000s but continued to decrease after 2008. These problems, in turn, affected the size of abalone. The usual abalone size for market was 10~12 shells per kg, but recently the size became smaller and smaller to 15~16 shells per kg. The change of size implies shift in consumption patterns: Consumers not only eat live abalone but also they cook soup with it. The size of abalone for uncooked dish is usually very big, like 10~12 shells per kg. In contrast, smaller abalone, such as 20~25 shells per kg, are used for making soup. Increasing use of smaller abalone leads to lower income of abalone aquaculture households. This is partly because that the size determines the price and the price gap between big abalones and smaller ones is extreme in Korea. For the sustainable growth of Korean abalone industry, we need to come up with strategies. First, a reasonable production system needs to be in place, especially for better management of abalone aquaculture grounds. Management of abalone licenses is also necessary because local governments issue relevant licenses as well as supervising abalone grounds. Second, abalone export destination need to be diversified. Japan, the major importer of Korean abalone, takes up a lion's share of export, at 95%. Third, new consumption style of abalone needs to be developed. Abalone used to be consumed as 'raw type' or Sashimi in Korea. This sole type of consumption hampers the growth of abalone market. Moreover, more strategies are needed to encourage and distribute home cooking of abalone rather than eating-out at restaurants. Last but not least, distribution system should be improved for better delivery of live abalone.

관세는 국가재정수입 또는 국내산업보호를 목적으로 수출입물품에 대하여 부과하는 조세이고, 관세환급은 원자재를 수입 가공해 만든 완제품을 수출할 때 해당 원자재의 수입 관세를 돌려주는 것으로 수출상품의 경쟁력을 지원하는 것이다. 특히 한국과 중국의 교역규모는 2010년 현재 다른 국가에 비해 가장 크므로 중국과 관련된 기업은 중국의 관세제도, 즉 관세환급에 대해 정확히 이해하는 것이 필요하다. 중국의 수출재화에 대한 증치세 관련 규정은 다소 복잡하고 일관성 없는 정책으로 인하여 이해하기 어렵기 때문에 본 연구의 결과는 의미가 있다. 또한 2010년 현재 한국의 경우 관세환급은 4조176억6백만원이고, 중국의 경우에도 7328억위안에 달해 금액으로도 그 중요성이 크다고 볼 수 있으므로 한국과 중국의 관세환급에 대해 비교하여 이해하는 것은 의미 있는 연구이다.

Purpose - This study examined the effect of tariff cuts on productivity in Korea's manufacturing industries and the effect of initial productivity level before tariff cuts on productivity improvement after tariff cuts. We also attempted to identify whether import-driven or export-driven factors are more important for productivity improvement, especially in low productivity industries. Design/methodology - Since tariff reduction is a policy decision that can affect cross-industry, its impact is spread across all industries beyond the scope of a single firm through the input and output network of industry structure. Accordingly, we proposed a new method to measure the change in productivity to reflect the impact of tariff cuts across industries. Through an Armington CGE analysis, changes in endogenous variables can be directly measured after the exogenous shock of tariff reduction, and the amount of movements in productivity triggered by tariff cuts can also be calculated. We can thus assess the effectiveness of exogenous policy, such as tariff cuts, through the difference between the benchmark and counterfactual values of endogenous variables. Findings - This study confirmed that tariff reduction positively affected productivity improvement in Korea's manufacturing industries. It also confirmed that productivity gains occur in Korea's leading export industries. Finally, greater productivity gains were recorded in the group with additional high-export-share or high-import-share conditions for low productivity industries. These results are, in a limited sense, consistent with the existing studies that emphasize the importance of exports and imports on productivity improvement, especially for low productivity industries. Originality/value - The results of our experiments are different from those of non-CGE studies, which measure the industry-level change in productivity with dummy coefficients, in terms of directly calculating the amount of change in productivity. In addition, we propose that the Armington CGE model is more appropriate than the Melitz CGE model to directly measure the productivity after tariff cuts. This is because the Melitz CGE model assumes the given specific productivity density, which does not change after an overall drop of tariffs. To the best of our knowledge, this approach to directly calculating productivity by reflecting the impact of tariff reduction across industries through CGE analysis, is unprecedented in this literature.
