We provide an analytical approach that facilitates understanding the bifurcation mechanism of a wide class of economic models involving spatial agglomeration of economic activities. The proposed method overcomes the limitations of the Turing (1952) approach that has been used to analyze the...

Based on two strands of research, namely ‘barriers to technology adoption’ and ‘appropriate technology’, we propose a formal reappraisal of ‘deep integration’, a broad concept often used in trade policy discussions. We then evaluate the 2004-7 EU enlargement wave utilizing this...

This paper introduces sectorial heterogeneity in TFPs in a growth model to generate new insights on trade, sectorial reallocation, and economic growth. The rate of overall economic growth in this model is a simple average of sectorial growth in a closed economy, but will depend on trade...

Resorting to the method proposed by Matsuyama (2013), this paper develops a static equi- librium model of a system of cities in which ex ante identical locations specialize in stages of production different in the degree of dependence on routine and nonroutine local services sec- tors, the...

We formulate a duopoly model with international location choice in the presence of global common ownership. We theoretically examine how payoff interdependence caused by overlapping ownership such as common and cross ownership affects location and production choices, and resulting welfare. We...

This analysis is a natural follow up of continued efforts to assess the consequences of cross-border mergers in industries with a vertical structure. Absent free trade, in a vertically related industry, the downstream firms will not choose the social optimum under spatial price discrimination...
