Econometric and other empirical issues

  Leading institution:
The task focuses on a number of econometric improvements to made in respect to the existing estimation or calibration of models on which UrbanSim is based:
  1. household location model should be consistent with variable size of potential locations, husband's and wife's respective preferences and constraints (current and potential labour place); the location decision should be modelled simultaneously with the decisions to live in a house/a regular flat/a low-price (social) housing (e.g. HLM in France), and to buy or rent the dwelling;
  2. consider firms rather than jobs as the decision unit for jobs location; decompose the evolution of the number of jobs at a given place in : variation in the number of jobs in each existing firm; firms relocation; births and deaths of firms;
  3. for the land use model, instead of estimating transitions probabilities from one usage to another, develop and estimate a model of generation of projects of a given type and size, and estimate a location model for these projects given the constraints imposed by their type and size.
 UCP


WP 5 will also investigate the possibility to estimate interrelated decisions entering different work packages (For example, life cycle effects in the car ownership and location decision process). However, difficulty to access the needed panel data will add to the difficulties raised by the theory of dynamic decisions.
