Does Korea’s official development assistance (ODA) promote its FDI?

강길성,원용걸 한양대학교 경제연구소 2017 JOURNAL OF ECONOMIC RESEARCH Vol.22 No.1

This paper empirically investigates whether Korea’s ODA promotes its FDI to recipient countries, using a dynamic panel analysis over the period from 1995 to 2012. The regression results reveal that total ODA, infrastructure aid, and technical assistance exert positive effects on Korea’s total FDI stock in the recipient countries. At the sectoral level, differences between manufacturing and service sectors are noticeable, implying that the so-called vanguard effect of ODA on FDI depends both on industrial sector and on the type of ODA. The positive effects of ODA on manufacturing FDI are confirmed only in loan-type ODA. Infrastructure-related aid shows no significant effects on FDI in services, but technical assistance and humanitarian aid are positively associated with service sector FDI. Our empirical findings suggest that Korea’s ODA plays a crucial role in facilitating its private investment flows to recipient countries, and thus it is important to formulate appropriate ODA policies favorable for private capital flows.

Highly Durable Platinum Nanoparticles on Carbon Derived from Pitch-Based Carbon Fibers for Oxygen Reduction Reaction

강길성,이철호,이윤기,채근석,Doh C. Lee,이성호,조한익 한국고분자학회 2017 Macromolecular Research Vol.25 No.12

Highly durable platinum (Pt) catalysts for oxygen reduction reaction (ORR) were fabricated using pulverized isotropic pitch based activated carbon fibers as catalyst supports. We controlled the textural and structural properties of catalyst support by heat-treatment with various temperatures of 900, 1200, 1500, and 2000 oC. Crystallinity of the catalyst supports increased with increasing heat-treatment temperature, leading to an increase of conductivity. In addition, the catalytic activity and durability increased and the catalyst using carbon supports heat-treated at 1200 oC showed a comparable performance and superior durability to those of a commercial catalyst. It is suggested that an increase in crystallinity was attributed to prevent elimination of Pt and carbon support, which led to less degradation of catalytic activity and durability for ORR. This work showed the possibility of pitch based activated carbon fibers as a highly durable catalyst support.

Is Korea Exploiting Its Trade Potentials in Africa? : Gravity Equation Analysis and Policy Implications

강길성 한국경제연구학회 2014 Korea and the World Economy Vol.15 No.1

This study analyzes the Korea-Africa trade flows that present a typical inter-industry trade pattern, using the gravity model and the Hausman-Taylor Method. A number of studies of Korea’s trade have been carried out previously; nevertheless, there hardly exists literature that focuses on the Korea-Africa trade. This exercise is a first-ever trial to investigate the Korea-Africa trade potentials by comparing the actual trade volume with the predicted one, through calculating fitted values based on regression coefficients. As a result, we find that the Korea-Africa trade still has room for expansion despite sharp increases in the decade. Among sub-regions, the western and southern African markets are particularly to be exploited further. We also confirm that tariffs, human networks and trade structure have significant impacts to Korea’s exports to Africa. To harness export potentials, Korea needs to be proactive in FTAs. It is also imperative to implement policy to strengthen human networks, for instances, capacity building programs of local trade facilitators. The trade complementarities with many African countries, including Algeria, are highly likely to evolve favorably for Korea’s exports with Africa’s continuous economic growth; hence opening up new opportunities for Korea’s exports and placing additional emphasis on policy efforts for favorable environment of trade with Africa.

한국의 해외직접투자 결정요인 재고찰: 아프리카는 다른가?

강길성,원용걸 한국국제경제학회 2018 국제경제연구 Vol.24 No.2

This paper identifies the main determinants of Korean FDI at both aggregate and sectoral level and examine whether those factors act differently in Africa. To this end, we conduct empirical analyses on FDI outflows from South Korea for 1995~2014 using Poisson pseudo-maximum likelihood (PPML) estimation method. The empirical results are: (a) openness, infrastructure and human capital are the main determinants of Korea’s FDI, but the dominant factors vary over different industrial sectors and regions; (b) the fact that host countries belong to the African continent is a disadvantage to attract FDI from Korean companies; (c) the lack of reliable infrastructure and human resources are key constraints to Korea-Africa investment partnerships, especially in the manufacturing and mining industries. Given the increasing request for Korea-Africa business partnership, Africa-focused and differentiated strategies are needed such as strengthening supports for infrastructure and human capital development and enhancing mutual understanding, especially through Korea’s ODA activities in Africa. 본 논문은 우리나라 해외직접투자(FDI)의 결정요인을 전체 및 산업별 FDI 수준에서 확인하고, 더 나아가 새롭게 떠오르는 대륙인 아프리카의 경우 다른 지역과 비교하여 직접투자 결정요인이 다른지를 살펴본다. 이를 위해 본 논문은 중력모형을 추정하는 방법으로서 포아송 유사최우도 방법(Poisson Pseudo-Maximum Likelihood Method)을 사용하여 1995~2014년간 한국의 해외직접투자 패널데이터를 분석한다. 분석결과는 첫째, 대외개방도, 사회기반시설, 그리고 인적자본은 한국의 해외직접투자 대상지 결정에 있어서 중요한 요인들이지만, 이들 간 상대적 중요성은 산업부문 및 지역에 따라 다르다. 둘째, 아프리카 대륙에 속한 국가들은 그 위치만으로도 한국으로부터 직접투자를 유치하는데 있어서 불리하다. 셋째, 부족한 사회기반시설 및 인적자본이 한-아프리카 투자협력, 특히 제조업 및 광업 투자에 있어서 중요한 제약요인이다. 이러한 분석 결과로 볼 때 한-아프리카 간 경제협력 논의에 있어 상호간 이해증진, 사회기반시설 및 인적자본의 확충 지원과 같은 아프리카 지역에 초점을 맞춘 차별화된 정책이 요구되며, 이를 위해 아프리카 지역에 대한 공적개발원조(ODA)의 적절한 활용이 필요하다.

Regulation and Service Exports: Theoretical and Empirical Analyses

강길성,원용걸 한국경제학회 2016 The Korean Economic Review Vol.32 No.2

This paper constructs a theoretical framework to analyze the impacts of deregulation on service exports using the monopolistic competition model developed by Krugman (1980). The framework entails two core claims. First, the positive effects of deregulation on service exports are more prominent in the differentiated or knowledge-intensive service sectors such as insurance, business, and cultural and recreation sectors than those in the standardized ones such as travel and communication sectors. Secondly, the trade-stimulating impacts of deregulation in exporting country are of larger magnitude than those of deregulation in importing country. We then empirically test and prove these arguments using the Hausman- Taylor estimation method and the World Bank’s STRI dataset. From these results, some policy implications are drawn for service industry development.

Does Korea’s Official Development Assistance Promote Its Exports?: Theoretical and Empirical Analyses

강길성 한국무역학회 2014 Journal of Korea trade Vol.18 No.4

This paper aims to contribute to narrowing the knowledge gap of aid effects on donor’s exports through theoretical and empirical analyses of various ODA types. To explain how aid affects donor’s exports, we constructed a theoretical framework that considers aid as "public goods" with externality effects. We also estimate augmented gravity equations using Korea’s bilateral exports and ODA data, employing Hausman-Taylor Method and system-GMM to address the endogeneity problem. Through the long-term analysis with aggregated data, we confirmed the positive effects of total ODA, loans, grants and economic aid but no such effect in non-economic (humanitarian) aid. At the sub-sector level, we found out that in some cases infrastructure aid had no effects and humanitarian aid showed positive effects, which was contrary to the results obtained analyzing aggregated data. These conflicting results imply that the effects of ODA on exports depend on both ODA types and industrial sectors. By comparing two distinct periods, we found out that the vanguard effects of ODA on donor exports have lasted even after untying aid was introduced. These results show that donors are not necessarily anxious about expanding untying aid, since they are highly likely to continue to benefit if aid packages are well designed. The government efforts to sophisticatedly make the combination of various ODA types would not only enhance the trade creation effects of ODA but also secure domestic supports for scaling up ODA; hence eventually helping the international community to mobilize financial resources.
