Korean inflation during the US military administration of 1945-1948: a further analysis

This paper investigates the dynamic process of Korean inflation under the US military administration using a structural vector autoregression (SVAR) incorporating cointegration relations among the variables. The results show that government expenditure shocks are primarily responsible for price movements together with money demand shocks having noticeable short-run impacts. The study also shows that government expenditure shocks are the most important source of fluctuations in each of the other variables investigated. The paper concludes that a reform of fiscal and monetary system is necessary to stop the sustaining process of inflation as well as fluctuations in other macro-variables.     

Trade-induced Industrialization and Economic Growth

Based on a modified Heckscher-Ohlin model of Deardorff and Park (2010 Deardorff, A. and Park, J.-H. 2010. A story of trade-induced industrialization. International Economic Journal, 24: 283–296. [Taylor & Francis Online] , [Google Scholar]), this paper develops a dynamic model of trade-induced industrialization and economic growth. It shows that a developing country may grow out of its autarky steady state with no industrialization into a new steady state with full industrialization by opening to trade with a large industrialized country, exporting the labor-intensive intermediate input in exchange for the capital-intensive intermediate input for the modern good. Even when the developing country is on its path toward complete industrialization under autarky, free trade may induce it to grow faster with its return to capital being raised and sustained at a level that is higher than its autarky level during its industrialization process. Once it completes its industrialization process by having all of its resources in the modern sector, then diminishing returns to capital come back to accompany further capital accumulation, slowing down the growth of the economy. This trade-induced industrialization and economic growth, having an expansion of international trade both in its absolute value and in its ratio to the size of the developing country, correspond well with the dynamic profiles of East Asian Miracle countries’ economic growth based on their export-oriented industrialization strategy.     

How should firms carry out technological diversification to improve their performance? An analysis of patenting of Korean firms

This research aims to analyze how a firm's technological diversification strategies influence its financial performances, in terms of ‘technological diversification’ in broad technology sectors and ‘technological concentration’ on its own core technology, especially in the case of Korean large firms. The data used in the analysis were panel data encompassing the years between 1990 and 2006, which linked Korean firms’ patent information registered in the United States Patent and Trademark Office to the financial data of those firms collected from Korea Investors Service, Inc. (Kis-Value). For the estimation of the panel data, a fixed effect model, which considers the individual firms’ own effect on the financial performance, was used. Tobin's q was used as a dependent variable representing firm performance, while ‘broad technology diversity’ and ‘core technology diversity’ were used as the focal explanatory variables. The results show that a firm seeking to have more technological assets should invest in a broad technological diversification strategy in its search for new business opportunities; it should likewise concentrate on the core technology in order to maintain its financial performance.     

E-commerce retail and reverse factoring: A newsvendor approach

This study builds a theoretical model to examine how supply chain finance (SCF) services using fintech can ease e-commerce suppliers' capital constraints. Despite the innovation in the logistics industry during the Fourth Industrial Revolution and the increasing online shopping in the post-COVID era, small e-commerce enterprises may fail to grow owing to their budget constraints. Reverse factoring is believed to ease such suppliers' capital constraints. We analyze the effect of reverse factoring using the capital-constrained newsvendor model, and we consider the impacts of additional funding from SCF services. Our results show that SCF services reduce e-commerce suppliers' initial orders and, thus, alleviate their budget constraints. This finding suggests that the discount factor of reverse factoring should be higher to ease small suppliers' budget constraints and allow the e-commerce industry to grow sustainably.     

The Economics of Forest Land Use in Temperate and Tropical Areas

This paper presents economic rules for harvest timing when timber and nontimber goods, services, and ecological functions are produced from forest stands. Forests include stands that are heterogeneous in age, land quality, and distance to market. Rules for allocating land between forest and nonforest use are developed. Key land use margins are identified that are important to land use allocation in temperate and tropical regions (e.g., between unmanaged forest, forest management, and forest conversion). Processes that can change key land use margins are discussed and used to organize recent empirical and theoretical studies of regions where forest land use is in transition, such as where forest land is being converted to alternative nonforest land uses.     

What matters to managerial knowledge acquisition in international joint ventures? High knowledge acquirers versus low knowledge acquirers

Although there is a general agreement amongst scholars that international joint venture (IJV) is a vehicle to acquire technology and knowledge from foreign parents, key factors differentiating high knowledge acquirers from low knowledge acquirers are not yet conclusive. For the purpose of this study, the samples are divided into two groups based on the extent of knowledge acquisition using cluster analysis. Then the two groups are examined to identify the main factors classifying the groups by using logistic regression. This study finds that managerial knowledge that has more sticky characteristics than technology is acquirable know-how. It also shows that trust between parents, international experience of IJV employees, and foreign parent’s support in various managerial functions will considerably increase the extent of knowledge acquisition for IJVs. In conclusion, based on the findings from this study, this paper offers suggestions to IJVs and multinational enterprises investing in Korea.     

Sectoral FTA gains,conflicts, and the role of interindustry factor mobility: Evidence from Korea's free trade agreement

Free trade agreements (FTAs) can ignite domestic conflicts between export- and import-competing industries over trade gains. However, if the factors of production, such as capital and labour, move freely across industries, the returns to factor owners will quickly converge. Then, sectoral conflicts over FTAs will be less likely to arise. We analyse the case of South Korea's FTAs to measure (a) sectoral FTA gains and (b) interindustry factor mobility and to examine (c) the role of interindustry factor mobility in mitigating sectoral conflicts over trade policies. South Korea is an ideal case study due to the low barriers to domestic geographic mobility and high trade dependence. Based on data on its trade with 252 countries and factor returns between 2002 and 2017, we find that export industries did not gain much from the FTAs, while the import-competing agricultural sector was the winner. Sectoral conflicts greatly decreased over 2008–2010. Interindustry capital mobility plays a significant role in weakening the sectoral conflicts, while the impact of interindustry labour mobility is limited.     

Dynamic adjustment of container stacking policy in an automated container terminal

The decision for good stacking positions for incoming containers in an automated container terminal is an important operational problem because it affects the productivity not only for stacking but also for later retrieval. This paper proposes an online search algorithm which dynamically adjusts and optimizes a stacking policy by continuously generating variants of stacking policies and evaluating them while they are actually being applied for determining the stacking positions. Simulation experiments show that the proposed algorithm is effective in enhancing the operational productivity, while other offline optimization methods are computationally infeasible to be applied to this problem.     

The economic cost of the Islamic State on the Syrian and Iraqi economies

In this paper, we evaluate the economic cost of the Islamic State on the Syrian and Iraqi economies from 2010 to 2016. To do so, we use the Post-Terrorism Final Economic Damage Simulator—PTFED-Simulator. The PTFED-Simulator assesses the economic damage of terrorism based on ten different indicators: (1) total regional terrorism tension (?T_t); (2) harmonized anti-terrorist strategy (AT₊); (3) war losses from terrorism (?πt); (4) total economic leakage from terrorism (?Ψt); (5) economic desgrowth from terrorism (?δ_t); (6) military dimension of terrorism (MD_t); (7) post-terrorism economic damage (?Π_t); (8) post terrorism economic damage evaluation; (9) post-terrorism reconstruction plan (PTR_t); and (10) terrorism effect on mega-disk networks mapping. Overall, we seek to evaluate the impact of terrorism on economic performance from a multi-dimensional perspective in both the short run and long run.     

Knowledge sharing,work–family conflict and supervisor support: investigating a three-way effect

Despite the importance of knowledge sharing in competitive environments, there is a paucity of studies examining the relationship between employee knowledge sharing and work–family conflict. Drawing on insights from conservation of resources theory, this study investigated how employees may reduce their knowledge-sharing behaviors when they experience resources lost from work interference with family (WIF) or family interference with work (FIW). Furthermore, the role of supervisor support in the relationship among WIF, FIW and knowledge sharing was explored as a valuable resource. Using data collected from 159 employees in South Korea, we found support that WIF is negatively related to knowledge sharing. In addition, the role of supervisor support in the relationship among WIF, FIW and knowledge sharing was the strongest when WIF is low and FIW is high, thus supporting the hypothesized a three-way effect. Theoretical and practical implications are discussed.
