We argue that identification problems bedevil most applied spatial research. Spatial econometrics solves these problems by deriving estimators assuming that functional forms are known and by using model comparison techniques to let the data choose between competing specifications. We argue that...

Using a hedonic property value price approach, we estimate the amenity value associated with proximity to habitats, designated areas, domestic gardens and other natural amenities in England. There is a long tradition of studies looking at the effect of a wide range of environmental amenities and...

Economists have long been sceptical of claims about the 'death of distance' - the idea that new technology has diminished the significance of geography for economic outcomes. Research by Sokbae Lee, Rachel Griffith and John Van Reenen, which looks at patent citations over a quarter of a century,...

How much does US-based R&D benefit other countries and through what mechanisms? We test the "technology sourcing" hypothesis that foreign research labs located on US soil tap into US R&D spillovers and improve home country productivity. Using panels of UK and US firms matched to patent data we...

We examine the “home bias” of international knowledge spillovers as measured by the speed of patent citations (i.e. knowledge spreads slowly over international boundaries). We present the first compelling econometric evidence that the geographical localization of knowledge spillovers has...
