Together with Piet Eichholtz and David Geltner, I have written a new paper on land assembly and urban renewal spanning 180 years. It has just been accepted for publication in Regional Science and Urban Economics.
Inner city redevelopment frequently involves the assembly of small lots into bigger ones. We analyze joint lot development and the influence of coordination and transaction costs of land assembly on the exercise of the redevelopment option, using Amsterdam micro housing information for 1832, 1860 and 2015. In all, we have a complete set of building structure and household characteristics for dwellings on almost 30,000 lots for each of these years. We estimate a logit model to predict joint lot redevelopment, based on structural characteristics of lots and dwellings and on social characteristics of their occupants.The results show that both types of characteristics significantly explain land assembly, and the regression coefficients adhere to the theoretical land assembly literature. This paper contributes importantly to our knowledge of the specific land parcel and structural physical characteristics that impact redevelopment. To our knowledge, this is the first paper to study the joint characteristics of the potentially combinable lots, and to document and quantify the role of social characteristics in land assembly.

Notes: The maps above provide information on the pairwise redevelopment of lots between 1832 and 1860, and between 1832 and 2015. Redeveloped lots are denoted in red, unchanged lots in blue. The maps are based on Amsterdam’s cadastral maps for 1832, 1860, and 2015.
