TitleNonlinear models with spatial dependence
ParticipantsLuís Silveira Santos (Principal Investigator)
SummaryThe present project aims to contribute to the spatial econometrics literature, regarding the
specification and estimation of a parametric model for fractional dependent variables on the
interval [0,1]. In recent years, several authors discussed the importance of modelling
cross-sectional dependence in spatial data, due to the interactions established between different
units (regions, firms, …) inside the same country or a well-defined area. Ignoring such dependence
structure may lead misleading economic interpretation and biased estimates. With regard to the
complexity of introducing these spatial interactions in the estimation, innovative methods and
algorithms will be introduced. The finite sample properties of a new estimator will be discussed
based on an extensive Monte Carlo simulation study. Finally, these methods will be applied to study
the determinants of the proportion of regional expenditure on high-tech R&D in the United States
Metropolitan Statistical Areas. Unit-specific and spillover effects with be accounted for, in terms
of social, economic and technological growth over the neighboring areas.
