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...

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...

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...

To examine the role of shipping firms in the international research and development (R&D) rivalry, we build a two-country (exporting and importing), two-firm (exporting and local) duopoly model with a shipping firm. The exporting firm competes with the local firm in the duopoly market of the...

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...

We investigate government subsidy policies in which a home firm and a foreign firm choose to strategically set prices or quantities in a third market. We show that even though each firm can earn higher profits under Cournot competition than under Bertrand competition regardless of the nature of...

To consider the role of uncertain production cost resulting from complying with rules of origin (ROO), we formulate a Cournot oligopoly model of a free trade area (FTA). If exporters do not comply with ROO, they must pay an external tariff, and if they comply, they enjoy zero tariff but suffer...
