Hajime Takatsuka, Dao Zhi Zeng, Dao Zhi Zeng
Review of International Economics   26(5) 1084-1100   Nov 2018   [Refereed]
© 2018 John Wiley & Sons Ltd. Assuming an inelastic labor supply, existing studies show that a larger country has a higher wage rate and a higher individual income. We reexamine these results using a model with an endogenous labor supply and var...
Hajime Takatsuka, Dao Zhi Zeng
International Review of Economics and Finance   41 65-78   Jan 2016   [Refereed]
© 2015 Elsevier Inc. Assuming an outside good, the existing intra-industry trade models show that the domestic price index is lowered and the welfare is improved by unilateral nontariff protection against foreign products. Removing the outside goo...
Hajime Takatsuka, Dao-Zhi Zeng, Laixun Zhao
Resource and Energy Economics   40 57-84   May 2015   [Refereed]
© 2015 Elsevier B.V. This paper examines the relationship between resource development and industrialization. When transport costs are high, the region with a more valuable natural resource enjoys a higher welfare than the other region. However, a...
MORITA, Tadashi, TAKATSUKA, Hajime, YAMAMOTO, Kazuhiro
The Japanese Economic Review   66(4) 492-519   Dec 2015   [Refereed]
© 2015 Japanese Economic Association. This article examines the effects of globalization, by especially focusing on the relaxation of local equity requirements (LERs) in developing countries. By constructing an endogenous growth model, where profi...
Hajime Takatsuka
Papers in Regional Science   93(3) 595-617   Aug 2014   [Refereed]
I examine how unit tax and ad valorem tax affect firm location in a monopolistic-competition model with asymmetrically sized regions and a quasi-linear preference. Tax revenue is evenly distributed to all workers or evenly distributed to the worke...
Hajime Takatsuka, Dao-Zhi Zeng
The Annals of Regional Science   51(2) 593-620   Oct 2013   [Refereed]
We examine how the spatial economy with multiple industries is shaped when interregional trade costs and intraregional commuting costs are low. All industries are characterized by increasing returns to scale and monopolistic competition, and they ...
Toshiaki Takahashi, Hajime Takatsuka, Dao Zhi Zeng, Dao Zhi Zeng
Economic Theory   53(1) 213-238   May 2013   [Refereed]
This paper shows the equivalence of spatial inequalities in industrial location and in income by revisiting the home market effect (HME) without any homogeneous good based on a reconstructed footloose capital model. In this simple framework, spati...
Hajime Takatsuka, Dao Zhi Zeng, Dao Zhi Zeng
Journal of the Japanese and International Economies   26(3) 308-325   Sep 2012   [Refereed]
In this paper, we examine the effects of liberalization on industrial location and national welfare in a framework of new economic geography. Specifically, we explicitly incorporate arbitrary trade costs in both differentiated-good and homogeneous...
Hajime Takatsuka, Dao Zhi Zeng
Canadian Journal of Economics   45(3) 1062-1082   Aug 2012   [Refereed]
Most existing studies examine the home market effect (HME) in a framework with immobile labour as the only production factor and the assumption of a freely traded homogeneous good is known to be crucial for the HME to emerge. This study explores t...
Hajime Takatsuka
Journal of Regional Science   51(4) 784-803   Oct 2011   [Refereed]
This paper investigates the relationship between firm location and skilled-labor location. While existing new economic geography (NEG) models could not explicitly analyze the relationship due to their assumptions, I construct a new NEG-type model ...
