Understanding Residential Mobility: Joint Model of the Reason for Residential Relocation and Stay Duration
Residential relocation or mobility is a critical component of land use dynamics. Models of land use dynamics need to consider residential relocation or mobility behavior of households to be able to forecast future population demographics land use patterns critical to activity and travel demand forecasting. Unfortunately, very little is known about residential relocation behavior at the disaggregate level, both in terms of the reasons for relocation and in terms of the duration of stay at a given residential location. This paper aims to fill this gap in knowledge by formulating and estimating a joint model of the reason for residential relocation and the duration of stay at a location. The model is estimated on a data set derived from a survey conducted in Zurich, Switzerland that captures information about residential moves over a 20 year period spanning 1985-2004. The paper provides elasticity estimates demonstrating how the model can be applied to evaluate impacts of changes in exogenous factors on residential mobility events.
