Korea's Bilateral Trade with Japan and the United States: A Comparative Study

Taegi Kim,Hong Kee Kim 서울대학교 경제연구소 1999 Seoul journal of economics Vol.12 No.3

This paper examines the development of Korea's trade structure with Japan and the United States over the past 30 years. Three aspects of the trade structure are investigated: changes in trade patterns, changes in the decomposition of total trade growth, and import and export elasticities. We find that there are major differences between Korea's trade with Japan and Korea's trade with the United States: Korea's intra-industry trade with Japan is higher than that with the United States. The contribution of intra-industry trade to Korea's total trade growth has increased over time. The trade pattern of Korea with Japan has become more similar to that with the U.S. in terms of intra-industry trade while it has diverged from it in terms of inter-industry trade. Also, Korea's import and export price elasticities are larger for trade with the United States than for trade with Japan.

Changes in Variety, Price, and Quality of Chinese Export Products in Trade with Korea

Taegi Kim 한국경제연구학회 2013 Korea and the World Economy Vol.14 No.2

This paper analyses the changes in the variety, price, and quality of Chinese export products, and their contributions to China’s export growth into the Korean market, using HS 10-digit highly disaggregated Korean trade data between the years of 1992 and 2008. In this paper, empirical methodologies for estimating the price level and quality level of Chinese products are developed. Our results show that China’s export growth is mainly explained by an increase in the intensive margin, and that the rise in the intensive margin is due to a decrease in price and an increase in quality of Chinese products. Even if an increase in product variety and a decrease in price have contributed to China’s export growth, the improvement in product quality is the main factor affecting China’s rapid export growth into the Korean market.

Industrial Structure, Regional Trade Bias, and China's FTA with Korea and Japan

Taegi Kim,Jun-Heng Zhan 서울대학교 경제연구소 2006 Seoul journal of economics Vol.19 No.4

This paper investigates the potential for China's FTA with Korea and Japan. We examine the similarities of industrial structures and regional trade biases among the three countries as indictors for establishing a China-Korea-Japan FTA. Even though the three countries are at very different developmental stages, their industrial structures will converge over time and their regional trade bias is high. Regression results of the gravity equation show that the trade volume among the three countries will increase. Based on our analysis of industrial similarities, we suggest a step-by-step procedure for the economic integration of Northeast Asia. A successful China-Korea-Japan FTA can be realized through the initial establishment of Korea-Japan and China-Korea FTAs, followed by subsequent negotiations between these two FTAs.

수출품의 품질 변화가 수출가격과 수출점유율에 미치는 영향: 미국의 수입통계를 이용한 분석

김태기(Taegi Kim) 한국무역연구원 2019 무역연구 Vol.15 No.4

Purpose - This paper analyzes the effect of quality change on export price and export market share. We used U.S. import data classified with HS 6-digit covering the period from 1995 to 2015. Design/methodology/approach - The quality index was estimated by using the ranks of export prices by country. Findings - Results show that countries with higher income levels are exporting better-quality products, and countries that are geographically far away are exporting better-quality products. Overall, there is a positive relationship between price and quality. However, increases in prices reduce market share, but increases in product quality contribute to increases in market share. An increase of 10% in quality increases the export share by 2.65-2.83%. As in other studies, the larger economies have higher market shares, and the countries with longer distances have lower market shares. Research implications or Originality - Finally, the regression analysis reveals that Korean products are of better quality than those of other countries similar to Korea, and because of such better quality, Korea has a relatively greater market share than other countries.

한국 수출기업과 내수기업의 총요소생산성 비교 분석

김태기(Taegi Kim),김홍기(Hong Kee Kim) 한국경제연구학회 2015 한국경제연구 Vol.33 No.1

본 연구는 1985년부터 2010년까지 우리나라 제조업의 기업 자료를 이용하여 수출기업과 내수기업 간의 생산성 차이를 규명한다. 분석결과를 요약하면 다음과 같다. 첫째, 수출기업이 내수기업보다 총요소생산성의 증가율이 높고, 특히 최근에 올수록 그 격차는 커지고 있다. 둘째, 수출기업의 기준을 엄격하게 할수록 수출기업과 내수기업 간의 총요소생산성 증가율의 차이는 크다. 셋째, 총요소생산성 수준을 비교하면, 예상과는 달리 수출기업의 생산성 수준이 내수기업보다 높지 않았다. 이러한 분석결과는 수출이 새로운 생산기술 도입이나 지식 확산의 중요한 통로가 되고 있음을 의미하고 생산성 증가를 통한 지속적 경제성장을 달성하기 위해서는 수출역량이 떨어지는 기업들의 수출능력을 높이는 노력이 필요함을 시사한다. This paper aims at examining the differences of total factor productivity(TFP) between exporting firms and domestic firms, using firm data of manufacturing sector from 1985 to 2010. The empirical results show the followings. The growth rate of total factor productivity of exporting firms is higher than that of domestic firms. Also the difference of growth rates of TFP is increasing over the recent time. In particular, the growth rate of TFP of exporting firms are higher than that of domestic firms, as the exproting firms are defined with the higher export ratio. Finally the level of TFP of exporting firms are not higher than that of domestic firms. These results imply that the export is a main channel of technology spillover and knowledge diffusion. Therefore, enhancing the exporting capacity of small and medium firms is required for continuos growth though a higher increase in productivity.

한국 수출상품의 가격과 품질변화 분석

김태기(Taegi Kim) 한국경제연구학회 2010 한국경제연구 Vol.28 No.2

이 논문은 1992~2008년 기간 동안 HS 10단위의 세분화된 무역통계를 이용해 한국 수출품의 가격과 품질변화를 분석하고 있다. 분석방법으로 수입재에 비해 수출재의 가격이 더 비싼 제품의 수를 계산하고, 또 수출단가와 수출액을 이용해 품질지수를 추정하였다. 분석결과에 의하면, 한국 수출품에서 우위품질 품목수가 점차 증가하고, 또 품질지수도 점차 상승하였다. 이는 한국 수출품의 품질이 개선되어 왔음을 보여 준다 특히, 기계 및 운송산업(SITC 7)에서 품질의 증가율이 가장 높게 나타났고, 전반적으로 저기술산업보다는 고기술산업에서 품질개선이 이루어졌다. 또 상대적으로 수출액이 많은 산업에서 품질이 더 많이 개선되었음을 보여 준다. This paper analyzes changes of export prices and product quality in Korean exports using Korea's HS 10 digit trade data during 1992~2008. For this purpose, we calculated the number of products whose export prices are higher than import prices, and estimated quality index using unit value and volume of exports. The results show that the ratio of higher quality products to all products has increased over time, and quality index has also increased during the period. It implies that the quality of Korean exports has improved. In particular, the quality improvement is highest in machinery and transportation industry (SITC 7), and the quality in high technology industries has increased faster than that in low technology industries. Finally, quality improvement is higher in the industry with larger trade volume.

한중일 자동차산업의 국제경쟁력 비교 연구

김태기(Taegi Kim),린린(Lin Lin) 한국경제연구학회 2011 한국경제연구 Vol.29 No.3

이 논문은 한중일 자동차산업의 국제경쟁력을 비교하고 있다. 국제경쟁력의 지표로는 수출점유율, 무역특화지수, 현시비교우위지수, 그리고 국가별 노동생산성과 연구개발투자의 비중을 이용하였다. 분석결과를 요약하면 다음과 같다. 자동차산업의 국가별 노동생산성과 연구개발투자의 비중을 보면, 일본이 가장 높고 다음으로 한국, 중국의 순이다. 수출시장 점유율, 무역특화지수, 비교우위지수 등의 지표를 보면, 한국의 국제경쟁력이 일본보다 낮지만 한국의 경제규모나 자동차 생산량을 고려한 회귀분석 결과에 의하면 한국이 일본보다 더 높은 경쟁력을 갖는 것으로 분석된다. 중국은 세계 제1의 자동차 생산국으로 도약하였지만, 여전히 한국이나 일본보다 국제경쟁력이 낮다. 하지만 자동차산업에서 중국의 국제 경쟁력은 매우 빠르게 증가하고 있고, 특히 부품부문에서 그 성장속도가 빠르다. This paper analyzes international competitiveness of automobile industry among Korea, China, and Japan. We calculated labor productivity, R&D investment share to total output, export market share, trade specialization index, and revealed comparative advantage index as the measures for international competitiveness. The results are as follows. In the aspects of labor productivity and R&D investment share, Japan’s position is higher than Korea and China. According to indexes using trade data, Korea looks less competitive than Japan. However, the regression results, which controls economy size and automobile production size, show that Korea is more competitive than Japan. China’s international competitiveness is very low compared to Korea and Japan, but its competitiveness in automobile industry, particularly in automobile parts sector, has increased very fast.

Spontaneous Bladder Perforation in a Patient with a Long-Term Intraurethral Catheter

Choi Taegi,Lee Hyunkyung,Kim Junseok,Lee Sunghoon,Cho Younkyung,Kang Eunyoung,Kang Jinsun,Lee Sumin,Na Eunju 대한요로생식기감염학회 2023 Urogenital Tract Infection Vol.18 No.3

Urinary catheters are commonly used to address various urinary problems. However, the catheter itself can be a cause of several complications, including catheter-associated urinary tract infections, damage to the bladder and kidneys, and, in extremely rare cases, bladder perforation. We present a case of spontaneous bladder perforation in a patient who had a long-term indwelling intraurethral catheter. The patient with prior hypoxic brain damage suddenly developed tachypnea, tachycardia, and oxygen desaturation. Computed tomography and retrograde cystography revealed an extraperitoneal bladder perforation with an intra-pelvic abscess. Antibiotics were prescribed and a urinary catheter was inserted for drainage. After 11 weeks, the abscess resolved, and the catheter was removed to enable self-voiding. The perforation was attributed to chronic inflammation and distension of the bladder wall caused by the intraurethral catheter. Given the potential complications associated with long-term urinary catheterization, the timely removal of indwelling catheters should be considered.

한국 제조업 기업에서 토지보유가 투자에 미친 영향

김태기(Taegi Kim),오근엽(Keunyeob Oh) 한국경제연구학회 2013 한국경제연구 Vol.31 No.2

본 연구는 한국에서 기업의 토지보유가 투자에 미치는 영향을 분석하고 있다. 연구의 대상 기간은 1980년부터 2008년까지이고, 대상 기업은 제조업의 132개 기업이다. Modigliani-Miller 정리에서는 투자의 크기는 자금조달 방법과는 무관하다고 주장하고 있지만, 미국이나 유럽 등과 달리 자금 대출에서 담보제공 요구가 일반적인 일본이나 한국에서는 기업의 토지보유가 담보가치 기능을 하여 투자에 영향을 미쳤을 것으로 생각된다. 회귀 분석 결과는 한국의 경우도 일본과 마찬가지로 토지보유나 현금보유가 투자에 영향을 미침을 보여준다. 하지만 외환위기 이후에는 이러한 영향이 약간 감소하였다. This paper investigates whether the size of investment in Koreans firms is related with the land value of the firms. For the period of 1980 to 2008, we analysed 132 Korean firms’ data. According to Modigliani-Miller, the investment has nothing to do with the financing methods under the assumption of perfect information. But we expect the investment of the Korean firms depends on the land value since there could asymmetry of information in Korean firms case and the commercial banks tend to ask the firms to provide the land as the collaterals, as in Japanese firms cases. The results of rigorous regressions in this paper shows that Korean firms’ investment relies on the land value and cash flows in the firms. But this effects seems to have been smaller after east Asian currency crisis.
