Asymmetric international transport costs and tax competition: the influences of third country
広瀬恭子(九州産業大学)
京都大学法経済学部東館1階 103演習室
要旨:We extend the model of Haufler and Wooton (1996) and construct a model with three countries in which a firm selects its location. A firm can select a location country from two countries, while in the third country, there is a market for the firm and are competitive rival firms. Then, the effect of the third country's market induces the firm to locate at a closer country from the third country. On the other hand, the effect of the existence of rival firms makes the firm to locate at a further country from the third country. With this framework, we study the location behavior of the firm, and consequences of tax competition between two countries and two countries' trade union.

Structural estimation and interregional labour migration: Evidence from Japan
近藤恵介(神戸大学・院)
京都大学法経済学部東館1階 103演習室
要旨:This paper empirically tests the relationship among wage, market potential and interregional migration using structural estimation method in the framework of economic geography. We investigate migration of manufacturing workers between 47 Japanese prefectures. As a result we find that nominal wage is positively correlated with market potential and higher real wage prefecture attracts workers.

A game theoretical analysis of port competition (with Paul T-W Lee, and Y-T Chang)
手塚広一郎(福井大学)・石井昌宏(上智大学)
京都大学法経済学部東館1階 103演習室
要旨:This paper examines the effect of port competition between two ports applying a game theoretical approach. We constructed a conceptual non-cooperative game theoretical model and this study intends to empirically apply the model to a competition case between the port of Busan and the port of Kobe. The results show that Japanese government decided conversely on pricing and the timing of capacity expansion, which explains why the Kobe port has resulted in deteriorating cargo throughput over the times.

Effects of type and proximity ofpPartners in R&D cooperation of small and medium-sized firms in Zhongguancun, Beijing
亀山嘉大(香川大学)
京都大学法経済学部東館1階 103演習室
要旨:Using the original survey data conducted to small and medium-sized firms in Zhongguancun Science Park (ZSP), we examine the effects of R&D cooperation on firms' intensity of R&D activities, with particular attention to type and proximity to partners like large sized firm, other small and medium-sized firm, and university and research institute. We found that direct effects to enhance employment R&D intensity of ZSP small firms from research cooperation with small and medium-sized firms, and university and research institute that are located nearby. Our results also suggest that indirect effects of research cooperation such that cooperation with nearby large firms and that with far-off small and medium-sized firms enhance further R&D of ZSP small firms when such cooperation yields commercial success.

Do poor procurement conditions always lead to poor performances? The interplay between procurement conditions and product positions
松島法明(大阪大学)
京都大学経済研究所本館1階 第二共同研究室
要旨:This paper describes how differences in costs between downstream firms affect their relative performance in a Hotelling-type location model. I consider three aspects of production costs in discussing the effect of cost advantage on firm performance: (i) costs to differentiate their products, (ii) efficiencies of production, and (iii) endogenously determined input procurement conditions. I show that a less efficient firm can be the market leader if the per-unit production cost of each firm depends on its location (costs to differentiate their products exist) and if the firms procure inputs from outside suppliers. That is, the profit of a less efficient firm can be larger than that of a more efficient firm. In equilibrium, the less efficient firm locates closer to the center than the efficient firm. This equilibrium outcome is quite different from that in which the efficiency difference is given exogenously. Moreover, I investigate how a change of cost structures affects the profits of firms. I show that improving the procurement conditions of a firm does not always increase its profit, whereas improving its production efficiency always does.

Growth, aglomeration, and uan congestion
藤嶋翔太(Washington University in St.Louis・院)
京都大学経済研究所本館1階 第二共同研究室
要旨:By adding housing congestion to the model of Fujita and Thisse [Does geographical agglomeration foster economic growth? And who gains and who loses from it? Japanese Economic Review 54 (2003), 121-145], we study interactions among growth, agglomeration, and urban congestion. However, unlike Fujita and Thisse (2003), we formulate the model as a one-shot game and take an evolutionary game-theoretic approach for stability analysis. Our approach is simple and enables us to analyze stability of nonstationary equilibria. We show that if both expenditure share for housing and transport cost are small, a stable steady-state equilibrium does not exist. Moreover, in such a case, we show that there can exist a stable nonstationary equilibrium.

Urban residential growth and decline in an open city
織田澤利守(神戸大学)
京都大学経済研究所本館1階 第二共同研究室
要旨:Not a few cities around the world have experienced population decrease during the past several decades. The change in population is a key factor of urban development process. For the case of increasing population, Fujita[9], Wheaton[15] and others investigate spatial patterns of residential development, but no previous papers take account of decreasing population. This paper provides a framework to examine urban spatial dynamics on both growing and declining phases of an open monocentric city. Specifically, the paper examines when, where, and how the land is developed, renewed and returned to agricultural land (or abandoned). Conclusively, the paper shows several transition patterns of land use, and clarifies which economic condition brings about such patterns.

Endogenizing leadership in tax competition: The role of capital ownership
小川光(名古屋大学)
京都大学経済研究所本館1階 第二共同研究室
要旨:This paper extends the work of Kempf and Rota-Graziosi (Journal of Public Economics, 2010, 94, 768-776), which argues that the sub-game perfect equilibria (SPEs) correspond to two Stackelberg outcomes under capital tax competition. The findings show that their result depends on the form of capital-ownership, that is, absentee ownership. By generalizing the form of capital-ownership, this paper shows that the simultaneous-move outcome prevails as an SPE if the capital is owned by residents in the countries, whereas the Kempf and Rota-Graziosi argument holds if the capital is owned by absentee owners.

サービス・イノベーション研究:IKEAの事例
浜口伸明(神戸大学)
京都大学法経総合研究棟8階 リフレッシュルーム
要旨:日本経済の主要なシェアを占めるサービス産業の生産性を向上させ、新たなイノベーションを促進することは、経済成長、より暮らし良い社会の創出、製造業の革新を導出するなど、重要性を持つ。IKEAの事例は、統一規格、効率的な大量生産と大量輸送によって、消費者に安価な商品を提供しているが、安価なだけではなくIKEAのデザインのアイデンティティを確保し、店舗の効果的なディスプレイによって、消費者が自宅の暮らし方を変えるホーム・ファーニシングをインスパイアされる喜びを提供している。統一規格の下でありながら、市場のローカルな特徴に応じて、製品のサイズやボリュームを調整することでローカリゼーションを実現する。製品デザインはスウェーデン本社で管理しながら、消費者との細かなインターフェイスは各店舗に委ねられていることに特徴がある。このような低価格化と消費者へのユニークな価値の提供を両立しているところにIKEAのサービスイノベーションがあるといえる。
