Trade Openness and City Size with Taste Heterogeneity

Abstract

This paper incorporates taste heterogeneity, as a dispersion force, into Fujita et al.'s New Economic Geography model. By doing so, agglomeration of both firms and workers is the result of market and non-market interactions. We analyze the outcomes of the original model vis-à-vis the outcomes of its extension. In particular, we assess the impact of international trade openness on cities' size. Two main general predictions arise from such a departure. First, the breakpoint with taste heterogeneity is higher than the breakpoint associated without it. Second, for low levels of trade openness urban agglomeration is attenuated with taste heterogeneity. Finally, based upon particular values of the parameters of the model, market outcomes converge to the optimal social welfare outcomes as taste heterogeneity increases.

Ouverture commerciale et tailles des agglomérations avec hétérogénéité des gouts

Résumé La présente communication incorpore l'hétérogénéité des goûts, en tant que force de dispersion, dans le nouveau modèle de Géographie économique de Fujita et al. De cette façon, l'agglomération d'entreprises et de travailleurs constitue l'aboutissement d'interactions commerciales et non commerciales. Nous analysons les résultats du modèle original en fonction de ceux de son extension. Nous évaluons, en particulier, l'impact de l'ouverture commerciale internationale sur la taille des villes. Cette nouvelle orientation donne lieu à deux prédictions générales principales. Premièrement, le seuil tenant compte de l'hétérogénéité des goûts est plus élevé que le seuil connexe sans cette dernière. Deuxièmement, en présence de bas niveaux d'ouverture commerciale, l'agglomération urbaine est atténuée par l'hétérogénéité des goûts. Enfin, en fonction de valeurs particulières des paramètres du modèle, les conséquences commerciales convergent vers les résultats optimaux de l'assistance sociale au fur et à mesure de l'augmentation de l'hétérogénéité des goûts.

Apertura comercial y tamaño de ciudad con heterogeneidad en los gustos

Extracto Este trabajo incorpora la heterogeneidad en los gustos, como una forma de dispersión, en el modelo de Nueva Geografía Económica de Fujita et al. Por este medio, la aglomeración de empresas y trabajadores es el resultado de interacciones de mercado y de no mercado. Analizamos los resultados del modelo original frente a los resultados de su extensión. En particular, evaluamos el impacto de la apertura del comercio internacional sobre el tamaño de las ciudades. Dos predicciones principales surgen de tal desviación. En primer lugar, el punto límite con heterogeneidad en los gustos es más alto que el punto límite asociado sin ella. En segundo lugar, en niveles bajos de apertura comercial, la aglomeración urbana es atenuada con la heterogeneidad en los gustos. Finalmente, basados en valores particulares de los parámetros del modelo, los resultados del mercado convergen con los resultados de bienestar social óptimos a medida que la heterogeneidad en los gustos aumenta.

     

Urban Citizenship,the Right to the City and Politics of Disability in Istanbul

Since the late 1990s, the ‘urban citizenship’ literature has accentuated the burgeoning potential of the city as host to more democratic interpretations of citizenship. A more recent literature highlighted the ‘local trap’ in such assumptions, arguing that the local cannot exist outside of neoliberalization. This article examines some of the recent institutional transformations in Istanbul's local government and seeks to understand where these might be situated in this discussion. Three institutions dealing with disability are scrutinized with regard to their power dynamics, discourses and practices. The argument is that, although superficially such developments seem to represent some of the tendencies highlighted by the urban citizenship literature (in terms of their scale, timing and appeal to a group previously excluded from modern citizenship), deeper analysis shows that these often promote charity‐ rather than rights‐based approaches. This is because the push factors in the emergence of these institutions are not the urban struggles on the part of the disability community, but rather the ruling party's populism, the impact of supranational agencies and the demands of non‐disabled residents at district level. Each of the three institutions examined is shaped primarily by one factor, leading to differing degrees of charity‐ and rights‐based practices. Arguments concerning the prospects of more democratic interpretations of citizenship at local level need to consider experiences in diverse settings.

AGAINST THE COLONIZATION OF URBAN DEVELOPMENT: The Top-dong Right to the City Movement in Jeju,South Korea

The Top-dong Movement was an extensive residents’ resistance mobilization against the Top-dong Public Water Reclamation project in the late 1980s in Jeju, South Korea. Starting as a local female divers’ struggle for subsistence, the Top-dong Movement grew into a collective action to reveal the illegalities of the project, demand that profits should be fairly shared and assert self-determination. State-led development of Jeju in the post-Korean war period functioned to render the island an extractive periphery during South Korea's capitalist modernization. Within that context, the Top-dong reclamation project exemplifies how urban development projects create colonial conditions in local communities by dispossessing them of land and the means of subsistence, commodifying public resources and extracting profits. Jeju islanders reacted by claiming specific rights: female divers’ collective rights to public water and the means of livelihood against dispossession; local residents’ rights to control developmental profits against extraction; and islanders’ rights to participate in decision-making processes against exclusion. Bridging Lefebvre's two concepts—colonization and the right to the city, this article argues that the historically situated, place-based right to the city movement revealed the colonization involved in urban development and performed practices of decolonization.
