New economic geography with heterogeneous preferences: An explanation of segregation
曽道智(香川大学)
京都大学経済研究所本館1階 第二共同研究室
要旨:Tiebout hypothesis (residential choice depends solely on local public goods) is extensively applied to explain geographic segregation. However, Rhode and Strumpf (2003) find that the Tiebout hypothesis is inconsistent with the long-period empirical data, and therefore a non-Tiebout explanation is needed. This paper provides such an explanation based on the new economic geography framework, into which the heterogeneous preferences of mobile workers on private goods instead of public goods are incorporated. Specifically, two types of mobile workers have different preferences on the products of two industries in the manufacturing sector in a symmetric way. The rigorous general equilibrium analysis conducted here shows that the increasing-returns technology and monopolistic competition form a mechanism endogenously leading to persistent residential segregation. There is an evolving path with decreasing transport costs, in which the two types of mobile workers are segregated, while two industries evolve from dispersion to agglomeration.

Intergenerational linkages and rconomic geography
村田安寧(日本大学)
京都大学経済研究所本館1階 第二共同研究室
要旨:This paper presents a model of economic geography with overlapping generations. Individuals are assumed to decide their location by considering not only where to sell their products when young but also where to buy others’ products when old. The present generation is thus linked to the past generation by a ‘dynamic’ wage equation and to the future generation by an ‘expected’ price index. Such intergenerational linkages induce a strong dispersion force, i.e., without any conventional dispersion force, a symmetric steady state is stable even in the presence of product diversity. Symmetry breaks when the discount factor is sufficiently small. This implies that once intergenerational linkages are taken into account, consumers care about how many varieties are available at which stage of a life cycle. Specifically, the model illustrates the case in which ex ante identical agents in the same generation may be divided into ‘ants’ and ‘grasshoppers’, i.e., those who earn a higher lifetime income and enjoy greater product diversity when old, and those who earn a lower lifetime income and enjoy greater product diversity when young. Finally, the model also suggests a definition of dynamic efficiency of agglomeration and dispersion.

Decentralization and open economies
佐藤主光(一橋大学)・林正義(財務総合政策研究所)
京都大学経済研究所本館1階 第二共同研究室
要旨:Openness of economy may or may not accelerate decentralization. We setup a new formal model which captures the essence of the nexus of openness and decentralization where interaction between openness and regional disparity is highlighted. We then empirically examine the effects of openness on decentralization, and especially, validate propositions implied by our theoretical analysis.

The effects of density and crowding on market entry behavior in geographical space
山鹿久木(筑波大学)
京都大学経済研究所本館1階 第二共同研究室
要旨:This study explores the antecedents of the spatial variation in market entry rates and extends the density dependence model by relaxing its assumption regarding firm heterogeneity. We argue that market entry is an outcome of new entrants' efforts to resolve competition and uncertainty problems, we theorize and demonstrate interrelatedness between organizational density and market crowding. Using panel data from the Tokyo hotel industry, our analysis not only supports the density dependence model and builds on it by demonstrating that new market entry is more likely to occur when market crowding is low and density is high or density is low and crowding is high.

Competing for capital when labor is heterogeneous (with J.-F. Thisse)
佐藤泰裕(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 investigates the impacts of capital mobility and tax competition in a setting with imperfect matching between firms and workers. The small country always gains and the large country always loses from tax competition, thus implying tax competition leads to redistribution from the large to the small country. However, the large country always attains a higher utility than does the small country. These results imply that our model encapsulates both the "importance of being small" as well as the "importance of being large". We also show that tax harmonization leads to redistribution from the large to the small country.

Unemployment, trans-boundary pollution, and environmental policy in a dualistic economy(福山博文と共著)
内藤徹(釧路公立大学)
京都大学経済研究所本館1階 第二共同研究室
要旨:This study is intended to examine the effects of environmental policies on employment, the use of polluting goods, and the unemployment rate under a model introducing trans-boundary pollution affecting the productivity of the other productive sectors. That model was designed by Copeland and Taylor [5], transformed into a dualistic economy model, as constructed by Harris and Todaro [10]. Results of our analyses show that reinforcement of environmental policy through control of emissions taxes does not necessarily worsen unemployment in the urban area. Therefore, we show that it is no usually proper to maintain that some environmental pollution can not be avoided to establish economic development.

Tax competition, location, and horizontal foreign direct investment(with Pierre M. Picard)
Kristian Behrens(CORE, Université catholique de Louvain)
京都大学経済研究所本館1階 会議室
【ミクロ経済学・ゲーム理論研究会と共催】 要旨:We develop a two-country model of capital tax competition in which firms choose both their location and their number of plants. When firms operate only a single plant, capital is subsidized in equilibrium and firms' profits after subsidy are increasing in subsidies. In the presence of multinational firms capital may, on the contrary, be taxed in equilibrium, provided that being multinational generates sufficient rents. Further, firms' profits after subsidies are decreasing in subsidies due to the pro-competitive effects of more firms 'going multinational'. This pro-competitive effect can give rise to multiple equilibria, one of which may be a 'subsidy trap' characterized by too many multinationals, high subsidies, and low welfare.

GISにおける新たな時空間データの分析について
貞広幸雄(東京大学)
京都大学経済研究所本館1階 第二共同研究室
要旨:近年、GISで利用可能な空間データはその質量とも、急速に充実しつつある。特に空間現象の時系列的な変化を記述する時空間データについては、様々な種類のものが利用可能になってきている。国勢調査、事業所統計調査、LANDSAT画像など、これまで長く研究に用いられてきたデータに加え、タウンページデータ、IKONOSなどの超高解像度衛星画像データ、レーザーによるトラッキングデータなど、新しいデータ取得技術によって得られる時空間データが現在では比較的容易に入手可能である。しかしながら、このような新たな時空間データを分析するための手法は未だ限定的にしか存在せず、データの有効な利用がなされているとは言い難い。そこでここでは、時空間データの利用可能性とその分析方法について、実例を交えながら広く論ずる。

所得格差の拡大と都市圏の空間構造
豊田哲也(徳島大学)
京都大学経済研究所本館1階 第二共同研究室
要旨:橘木らによって提起された所得格差論争では、所得再配分調査や全国消費実態調査などの全国値がもとになっており、地域間の所得格差が全く考慮されていないか、都道府県単位の言及にとどまっている。 本報告では、1983~2003年住宅・土地統計調査のデータを用いて、バブル期前後の東京大都市圏と京阪神大都市圏における距離帯別所得分布を検討し、所得格差から見た都市圏の空間構造の変化を明らかにする。

産業クラスター形成における製品開発型中小企業の役割 ― TAMA(技術先進首都圏地域)に関する実証分析に基づいて ―
児玉俊洋(京都大学)
京都大学経済研究所本館1階 第二共同研究室
要旨:地域的なイノベーションのメカニズムとして有効な産業クラスターの形成を図る上で、どの点に注目したら良いであろうか。本稿は、企業、大学など様々な構成員の中で、製品化、事業化の担い手である企業に注目する。中でも、地域性のある存在として中小企業に注目して、どのような中小企業に注目することが産業クラスターの形成に有効であるかを考察する。その方法としては、「産業クラスター計画」の先進事例として位置づけられているTAMAを事例として、同地域の企業アンケート調査から得られたデータによる計量分析に基づいて、「製品開発型中小企業が、産学連携及び企業間連携( 新技術・新製品の開発を目的とするもの)を有効に活用しており、従って、産業クラスター形成の有力な担い手となりうる」ことを検証する。あわせて、産学連携、大企業と中小企業の連携、中小企業間の連携の機能の比較を行う。
