Quality-adjusted population density (QAPD) is population divided by l and area that has been adjusted for geographic characteristics. We derive weights on these geographic characteristics from a global regression of population density at the quarter-degree level with country fixed effects. We...

We develop a new measure of land quality by estimating weights in a Poisson regression of population in grid cells on a vector of geographic characteristics and country fixed effects. Aggregating to the level of countries, we construct average land quality (ALQ) and quality-adjusted population...

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...

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...

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...

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...

In this paper, we argue ’buying local’ does not necessarily reduces transport-related greenhouse gas emissions even if transport and production technologies, as well as natural endowment are homogeneous in space. We develop a model of rural-urban systems where the spatial distribution of...

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...

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...
