Hedonic price indices are currently considered to be the state-of-the-art approach to computing constant-quality price indices. In particular, hedonic price indices based on imputed prices have become popular both among practitioners and researchers to analyze price changes at an aggregate...

Urban renewal areas are popular but empirically understudied spatial planning instruments designed to prevent urban decline and induce renewal. We use a quasi-experimental research design to study the effects of 22 renewal areas implemented in Berlin, Germany, to increase housing and living...

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...

Most housing transactions in London involve trading long leases of varying lengths. We exploit this feature to estimate the time value of housing --- the relationship between the value of a property and the length of time it will be owned for --- over the range 1-99 years. To do so, we compile a...

We exploit a unique panel of 75 metro areas ('cities') across the globe and employ a city-fixed effects model to identify the determinants of within-city changes in air pollution concentration between 2005 and 2011. Increasing car and population densities significantly reduce air pollution...
