Housing quality model : a user"s manual -- second edition

It includes changes in the solution algorithm, data requirements, and programming environment that were made in conjunction with the implementation of the HQM in Ecuador. Modifications were motivated by three key considerations. First, data on households and housing conditions in Ecuador were extremely limited, and it did not appear to be feasible to implement the Model for ten income deciles. Second, when we completed our initial simulations for Ecuador"s two major urban areas (Quito and Guayaquil), we concluded that the Model"s original treatment of net new households added each year was oversimplified and needed to be refined. And finally, a substantially revised version of the Turbo Pascal compiler was issued, enabling us to do away with some programming conventions which substantially reduced run times, and prevented us from adding new modules.
