Since the 1970s world trade in unprocessed wood or preprocessed wood reached a stable level between 150 and 200 million m3, while, since 1985, world consumption varies between 3.2 and 3.4 billion m3 annually1. Thus, woodwork networks seem to be caught between two worlds with virtually...

Les filières du bois à Tiruchengodu, petite ville de l’Inde du Sud, sont étudiées. Ce cas permet de comprendre l’articulation entre production à plusieurs niveaux d’échelle, dans une société très complexe. L’analyse du système de production montre le rôle initial de la...

We analyze the efficiency of urbanization patterns in a dynamic model of endogenous urban growth with two sectors of production. Production exhibits increasing returns to scale on aggregate. Urban environmental pollution, as a force that discourages agglomeration, is caused by domestic...

The Environmental Kuznets Curve (EKC) has given rise to a flourishing literature since the beginning of the 90’s. The EKC postulates an inverted U-shaped relationship between income and polluting emissions: there would be a level of wealth beyond which polluting emissions would decrease....

The paper combines an economic-geography model of agglomeration and periphery with a model of species diversity and looks at optimal policies of biodiversity conservation. The subject of the paper is "natural" biodiversity, which is inevitably impaired by anthropogenic impact. Thus, the economic...

A spatial welfare framework for the analysis of the spatial dimensions of sustainability is developed. It incorporates agglomeration effects, interregional trade, negative environmental externalities and various land use categories. The model is used to compare rankings of spatial configurations...

We present a statistical model of agrarian vineyard specialization in the province of Barcelona towards 1860, that combines the Boserupian push of population increase, the demand pull of a Smithian-type of growth (measured by the time-distances to the nearest seaport), and the agrological lands...

We analyze the efficiency of urbanization patterns in a stylized dynamic model of urban growth with three sectors of production. Pollution, as a force that discourages agglomeration, is caused by domestic production. We show that cities are too large and too few in number in uncoordinated...
