Foregone benefits of the open space that is sacrificed through urban sprawl are hard to quantify. We obtain a simple benchmark measure by introducing a demand for trips beyond the urban boundary into the monocentric city model. The externality arises from the increase in travel costs that...

Should constraints on urban expansion be relaxed because of external agglomeration economies? In a system of heterogeneous cities, we demonstrate that second-best land use policy consists of a tax on city creation and a subsidy (tax) on urban development in cities in which the marginal-average...

Does brownfield redevelopment warrant government support? We explore several external benefits in an urban general equilibrium framework. Preferences are modelled such that demand for housing units in the city is downward sloping, which yields a more general setup than the extreme open and...

We discuss how standard computable equilibrium models of trade policy can be enriched with selection effects without missing other important channels of adjustment. This is achieved by estimating and simulating a partial equilibrium model that accounts for a number of real world effects of trade...

The paper decomposes a geographical concentration index to examine the temporal scope of a spillover, which is the period of time over which one firm's activity directly affects the location of other firms' activities. Natural advantages are fixed over reasonably long time periods, but if...

Knowledge based firms like IT companies do neither have a capital- nor a land intensive production. They predominantly rely on qualified labour and increasingly depend on the location of its (potential) employees. This implies that it is more likely that firms follow workers rather than the...

Modern central business districts are characterised by high-rise office buildings. Helsley and Strange (2008) argue that skyscrapers are caused by agglomeration economies and a prize for being the tallest, so a reputation effect. We aim to test the relevance of this model by investigating the...

We provide empirical evidence on the role of labour market pooling in determining thespatial concentration of UK manufacturing establishments. This role arises because largeconcentrations of employment iron out idiosyncratic shocks and improve establishments'ability to adapt their employment to...

Rocketing rents in urban areas are likely explained by agglomeration economies. This paper measures the impact of these external economies on commercial property values using unique micro]data on commercial rents and employment. A measure of agglomeration is employed that is continuous over...

I define a composite amenity that provides aesthetic and consumption value to local residents: Urbanity. A novel data set of geo-tagged photos shared in internet communities serves as a proxy for urbanity. From the spatial pattern of house prices and photos I identify the value of urbanity in...
