“…Most notably, as demonstrated by, Ikeda et al . (, , ) it is now possible to formally predict the bifurcation path of stable equilibria in many‐region models by utilizing a combination of group‐theoretic and computational bifurcation theory (e.g., Ikeda et al . ()).…”

Literature from several phases of the career of Masahisa Fujita is surveyed chronologically, with a view toward future contributions in these areas. First we address the economic structure of the interior of a city with mobile consumers, adding production. Next we provide a critical discussion of the new economic geography, in particular distinguishing between recent approaches employing two regions and more than two regions, both in theory and in application to data. Finally, we discuss knowledge creation in groups and briefly touch on his current work in artificial intelligence.

“…Dado que a alternativa de cabotagem tem um custo inferior, a migração de carga de uma para outra modalidade poderia representar uma mudança na conformação das aglomerações relativas Norte-Nordeste/Sul-Sudeste em geral. Esta hipótese segue a literatura que mostra que diminuições no custo de transporte geram mudanças no equilíbrio do padrão das aglomerações produtivas entre regiões (Takahashi, 2007;Behrens et al, 2009;Akamatsu et al, 2012;Ikeda et al 2014).…”

Resumo: O objetivo deste estudo é evidenciar a complementaridade entre duas aglomerações produtivas (microrregiões de São Paulo e Manaus) e discutir a escolha do modal de transporte entre essas duas regiões. São Paulo caracteriza-se como uma aglomeração produtiva madura e diversificada; enquanto Manaus detém uma forte especialização. A partir de uma matriz de proximidade, pode-se afirmar que as microrregiões apresentam estruturas de produção complementárias. Quanto à estrutura de transportes, o comércio ocorre principalmente via modal rodo-fluvial e, em menor parte, via cabotagem. O potencial de migração para cabotagem é avaliado por uma pesquisa de escolha discreta. Os resultados indicam que esta transferência depende de características da condição de transporte (fretes, transit time, confiabilidade e regularidade do serviço) e da estrutura produtiva (como valor agregado do produto e tamanho da empresa).

“…As an early attempt to provide central place theory with a microeconomic foundation, Eaton and Lipsey (, ) showed the existence of a hexagonal distribution of mobile production factors (e.g., firms and workers) by a partial equilibrium approach without referring to the stability of the hexagonal agglomeration. Recently, theoretical studies on the existence of equilibria of hexagonal distributions and numerical analyses of their stability have been conducted (Ikeda, Murota, and Akamatsu, ; Ikeda and Murota, ; Ikeda et al., ). Hexagonal distributions observed in the numerical analyses were clearer in comparison with those on a square lattice (footnote 2).…”

This paper elucidates which agglomeration patterns exist in two‐dimensional economic space and how such patterns appear stably. Hexagonal lattices, that with and that without a boundary, are advanced, respectively, as practical and theoretical spatial platforms of economic activities. Agglomeration patterns on these lattices include hexagons in central place theory, but also encompass megalopolis and racetrack‐shaped decentralization. As the transport cost decreases, stable economic agglomeration undergoes the formation of the smallest hexagon and transition to patterns with larger market areas, often undergoing downtown decay but finally leading to a megalopolis. Formulas for break points are provided in an economic geography model.
