Radical uncertainty and the effect of transport infrastructure on land prices

Most contributions in the academic literature identify a positive effect of transportinfrastructure on land prices. However, their short-run dynamics has not been routinelyanalyzed. One of the reasons for this lack of research is because neoclassical urban land eco-nomics models underlie, in some cases implicitly, most of the available literature on the topic.In this theory, land values converge to their long-term trends regardless of short-termshocks. We build upon post-Keynesian monetary circuit theory to design a spatial urban economicstesting framework, building upon the contributions of Abramo (2011) and Alfonso(2007, 2017). In this tradition, short-term shocks have long-term effects on the spatial distributionof land values due to radical uncertainty. Our case study is Transmetro, a Bus RapidTransit (BRT) project in Barranquilla (Colombia). We use static and dynamic panel-estimationto test the short-run dynamics of spatial land price adjustments during 2000-2010, includingthe construction and delivery years 2006-2010. This case study offers a good assessmentopportunity because of featuring prominent problems and delays. We find volatileshort-run adjustments that run counter to neoclassical predictions, while resembling spatialland price adjustments exposed to radical uncertainty.
