The paper deals with the question of whether fiscal transfers re-ceived by cities can be justified by a higher cost of producing publicly provided goods. In the model, increasing the population density implies both a higher output per capita due to agglomeration economies and a higher cost of...

In a model on population and endogenous technological change, Kremer combines a short-run Malthusian scenario where income determines the population that can be sustained, with the Boserupian insight that greater population spurs technological change and can therefore lift a country out of its...

We use panel data from Germany to analyze the effect of population density on urban air pollution (nitrogen oxides, particulate matter and ozone). To address unobserved heterogeneity and omitted variables, we present long difference/fixed effects estimates and instrumental variables estimates,...

We use worldwide satellite data to analyse how population size and density affect urban pollution. We find that density significantly increases pollution exposure. Looking only at urban areas, we find that population size affects exposure more than density. Moreover, the effect is driven mostly...

Communities urbanize when the net benefits to urbanization exceed rural areas. Body mass, height, and weight are biological welfare measures that reflect the net difference between calories consumed and calories required for work and to withstand the physical environment. Across the United...

This paper studies the impact of building land limitations on within-city variation in urban density and its components crowding, residential coverage, and building height. We utilise geographical obstacles like steep inclines or water bodies as exogenous source of building land limitations...

We investigate the determinants of the fertility decline in Europe from 1830 to 1970 using a newly constructed dataset of linguistic distances between European regions. We find that the fertility decline resulted from a gradual diffusion of new fertility behavior from French-speaking regions to...

We look at a part of the spatial angle of economic growth. We introduce a new measure Spatial Population Concentration (SPC) that captures the weighted average population surrounding every person within a geographic area. The weights are a function of the distance between the person in question...

We use two surveys to assess why work from home (WFH) varies so much across countries and people. A measure of cultural individualism accounts for about one-third of the cross-country variation in WFH rates. Australia, Canada, the UK, and the US score highly on individualism and WFH rates,...
