  • Who gains from foreign direct investment-induced technology spillovers? Horizontal and vertical linkages

    Akinori Tomohara, Kazuhiko Yokota

    Australian Economic Review   46 ( 3 ) 312 - 324  2013.09  [Refereed]

     View Summary

    While the literature has explored the relationship between foreign direct investment (FDI) and productivity, a consensus has yet to be reached regarding FDIs impacts on the productivity of local companies, specifically with respect to vertical spillovers. This analysis extends upon previous works and sheds light on the necessity of distinguishing establishment characteristics when discussing potential benefits from FDI. The analysis shows that export-oriented establishments enjoy forward spillovers. Horizontal and backward spillovers are observed in local market-oriented establishments. These results lead to the conclusion that the literature during the 2000s shows country-wide spillover effects or averaged effects across industries. © 2013 The University of Melbourne, Melbourne Institute of Applied Economic and Social Research.

  • R&D Spillovers and Foreign Market Entry: Acquisition versus Greenfield Investment

    Kazuhiko Yokota, Kung-Ming Chen

    International Economic Journal   26 ( 2 ) 265 - 280  2012.06  [Refereed]

     View Summary

    This paper presents a three-stage game to model the entry behavior of a multinational firm in the presence of R&amp
    D spillovers. The multinational firm's entry mode choice - that is, to invest to set up a new plant or merge with a local firm - is a function of the magnitude of spillovers, as well as the relative cost of greenfield investment, and mergers and acquisitions (M&amp
    A). Our model shows that if there exist relatively high R&amp
    D leakages and relatively small difference in cost between M&amp
    A and greenfield investment, an R&amp
    D-intensive foreign firm tends to choose greenfield investment rather than M&amp
    A, while if there exist relatively low R&amp
    D leakages, the foreign firm is more likely to choose M&amp
    A rather than greenfield investment. It is also shown that the size of social welfare of the host country depends on the degree of R&amp
    D spillovers. These results produce strong implications for antitrust policy for particularly developing countries. © 2012 Copyright Korea International Economic Association.

  • Foreign direct investment and wage inequality: is skill upgrading the culprit?

    Akinori Tomohara, Kazuhiko Yokota

    APPLIED ECONOMICS LETTERS   18 ( 8 ) 773 - 781  2011  [Refereed]

     View Summary

    This article examines whether inward Foreign Direct Investment (FDI) is a source of wage inequality between skilled and unskilled labour in developing countries. Although the literature has explored wage inequality issues, we studied the impacts of FDI on skill upgrading comprehensively, together with trade and other factors (such as FDI externalities). Specifically, our analysis introduces the origin of FDI, controls for plant heterogeneity and relates the results to the FDI theory on Multinational Enterprises (MNEs). The results show that, on average, FDI caused wage inequality because of FDI-led skill-biased technological change. However, Japanese and Taiwanese investments helped to alleviate the inequality. Japanese and Taiwanese FDI is motivated by cost advantages achieved through vertical FDI and thus increases relative demand for unskilled labour.

  • Extending the learning-by-exporting hypothesis: Introducing a credit constraint

    Kazuhiko Yokota, Akinori Tomohara

    International Advances in Economic Research   15 ( 2 ) 169 - 177  2009  [Refereed]

     View Summary

    This paper develops a theoretical framework which can be used to examine policy implications from the learning-by-exporting hypothesis. This work builds on previous theoretical literature by introducing a credit constraint. When credit is available, the analysis suggests that supporting a learning sector via an export subsidy is not necessarily advised to improve social welfare. The learning sector's goods may be over-produced (relative to another non-tradable sector goods) when consumers can borrow freely for their consumption. If the learning sector's goods are over-produced, social welfare will be improved via a tax on production. © International Atlantic Economic Society 2009.

  • A decomposition of factors influencing horizontal and vertical FDI: A separate analysis

    Kazuhiko Yokota, Akinori Tomohara

    Eastern Economic Journal   35 ( 4 ) 462 - 478  2009  [Refereed]

     View Summary

    While the literature has explored which factors determine the emergence of different multinational enterprise (MNE) structures (i.e., horizontal or vertical MNEs), little attention has been paid to differences within the same MNE type. This paper proposes an index to distinguish horizontal foreign direct investment (FDI) from vertical FDI and tries to identify different FDI motivations within the same MNE type. The analysis indicates that industry type, FDI destinations, and the interaction of the two play an important role in determining MNE structures. Our analysis uncovers interesting FDI patterns from data and obtains a more nuanced typology of the US multinational affiliate activities.

  • Lewis Growth Model and China's Industrialization

    Nazrul Islam, Kazuhiko Yokota

    ASIAN ECONOMIC JOURNAL   22 ( 4 ) 359 - 396  2008.12  [Refereed]

     View Summary

    This paper examines China's industrialization in the light of the Lewis growth model. It begins with a perusal of Lewis's own writings and those of Fei and Ranis to clarify certain assumptions and predictions of the Lewis model. The paper then reviews previous applications of the Lewis model in studying industrialization of other countries, and notes the methodological problems that arise in this regard. In applying the Lewis model to study China's industrialization, the paper focuses on the dynamic relationship between wage and marginal product of labor in the traditional sector. For this purpose, the paper estimates a production function for China's agricultural sector using province level data and compares the estimated marginal product of labor with the corresponding wage of the sector. The results show that the marginal product has been increasing (from below) at a faster pace than the wage, as is predicted by the Lewis model. The results indicate that China as a whole is steadily moving toward the Lewis Turning Point.

     View Summary

    Japan’s two economic partnership agreements (EPA) are examined for analyzing the effects of trade liberalization on changes in exports and comparative advantage structure. I analyzed two Japan’s EPAs, Japan-Mexico, and Japan-Chile EPAs. In so doing, I construct two theoretical models: one is based on a heterogeneous firm model and the second is based on a Ricardian continuum good model incorporating intensive and extensive margins.The results show that the tariff liberalization increases intensive margin but not extensive margin in Japan-Mexico EPA, while it increases both extensive and intensive margins of Japan’s exports to Chile through the change in comparative advantage of Japan in Japan-Chile EPA. These findings suggest the importance of expanding FTA networks and promoting the use of FTAs in order to increase trade. Governments can contribute to an increase in the use of FTAs by implementing the measures such as disseminating the information about the benefits of using FTA

     View Summary

    企業のオフショアリングが日本の賃金格差の拡大に影響を与えたか、与えたとすればどの程度かを明らかにすることが本研究の目的である。日本ではオフショアリングの影響がしばしば産業空洞化と結びついて議論された結果,産業の雇用喪失が大きな論点とされ、賃金格差にまで議論が及ばなかった。本研究では日経NEEDS-FAME、Financial Quest、Astra Manager等のデータ・ベースを活用し、できるだけ詳細な産業別、企業規模別の主要データを採用する。現在,経済産業省『海外事業活動基本調査』、『海外事業活動動向調査』データ、東洋経済新報社『海外進出企業総覧』と合わせ、オフショアリングの企業規模別、職種別の主要なデータを収集中である。
    しかしながら望ましい賃金データが存在しないことが明らかになったので,CSR企業総覧データ・ベースから平均年間給与総額を従業員数で割ることによって代替する予定である。ただしこのデータはPDFファイル形式でしか入手できないので,現在のところ収集・整理に時間がかかっている。
    2013年度もこの方向で研究を進めてきたが,賃金データの入手がかなり困難であったため,むしろ理論研究に時間を使用した。理論研究ではオフショアリングが生じた場合,貿易にどのような変化が生じるかを検討している。貿易の拡大には主に2つの要因がある。一つはそれまで貿易していなかった財の取引が生じる効果と以前から取引されていた財の数量が増える効果である。そこで本研究ではこの2つの貿易の変化とオフショアリングの影響を考慮するモデルを考えた。
    今年度はこの理論モデルを完成させ,国内外の会議で発表し,コメントを得る予定である。

     View Summary

    Whether or not exports and foreign direct investment contribute to enhance the international competitiveness of the firms is an important question for both Japanese business circles and policy makers. This research project attempts to answer this question, using firm-level data and trade data. We examined the characteristics of the firms which enter into the export market and/or start foreign direct investment. Our project also examined whether or not the performance of firms improved after firm start exporting and/or foreign direct investment.

     View Summary

    Using the dataset of parts and components trade and Japanese FDI, we investigate the influence of FDI by Japanese firms on parts and components exports. Controlling endogeneity problems in estimation, we find that the positive effect of FDI on parts and components exports from Japan to the host countries. We also find that the demand of the Japanese market is important factor to determine the FDI and hence the volume of parts and components trade between Japan and the host countries. These findings imply that vertical production structure based on the factor endowments of the host countries has been developed by FDI-induced production networks.

  • Input variety, output variety, and economic development in East Asia

     View Summary

    In this study we investigated the relationship between trade structures at industry and firm level and firm's productivity for three countries. Especially we tested the impact of imported intermediate on firm's performance.
    In all three South-East Asian countries (Indonesia, Malaysia, and Thailand), productivity of foreign plants is higher than that of local plants. In Thailand and Malaysia, plants that export as well as import have higher labor productivity than the plants that don't. In Indonesia, it is found that there is a strong correlation between import and high productivity. In sum, in all three countries, imported intermediated goods play an important role for the productivity 'gains. In Thailand, trade barriers are negatively correlated with plant's productivity. This indicates the importance of trade liberalization for economic growth. In Malaysia, as expected R&D expenditure and IT investment are positively correlated with high productivity.
    As we discussed, foreign firms gain a large market share in Thailand manufacturing sector, especially, machinery industries. One of our main focuses of this study was on the effects of international trade on local firm's productivity. After controlling for the foreign factor, we found strong evidence that competition, imported inputs, and imported machinery at industry level and local firm's engagement in international trade are crucially important for firm's productivity.
