Research Summary:Paul Waddell is a professor in the Daniel J. Evans School of Public Affairs and the Department of Urban Design and Planning at the University of Washington, and is director of the Interdisciplinary Ph.D. Program in Urban Design and Planning. Over the past several years, his research has focused on modeling decision processes of households and firms related to urban development patterns, and the effects on these outcomes of transportation, land use, and environmental policies. The substantive aspects of this research deal with the factors influencing household residential mobility and location choices, firm decisions regarding location and employment levels, and real estate developer choices about housing and non-residential real estate development within spatially-detailed representations of metropolitan markets. The models are based on random utility maximization, and use discrete-choice models and Monte Carlo methods to simulate the interactions of households, firms, and developers within markets for real estate and labor, subject to individual constraints and influenced by public policies.
An aspect of this research of particular relevance to the current proposal is the treatment of residential mobility and location choice. Residential mobility and location choices have been modeled using multinomial logit models that estimate the independent influences of regional patterns of accessibility provided by the interaction between multi-modal transportation systems and the spatial distribution of employment and other opportunities, neighborhood socio-economic and housing composition, and housing prices, interacting with household characteristics such as income, age, presence of children, and number of workers in the household. This research is supported by a software architecture that is being developed with colleagues in computer science to facilitate multi-agent microsimulation modeling and the integration of interacting model components within a complex simulation system.
