Three Essays on the Spatial Autoregressive Model in Spatial Econometrics
The spatial autoregressive model (SAR) is a standard tool to analyze spatial data. It is of great interest in econometrics because it has a game structure and, therefore, can be interpreted as a reaction function: the outcome or behavior of observations at one location is directly affected by those …

The Simultaneous Spatial Autoregressive Model and Its Application in the Housing and Pharmaceutical Markets
… on the extension of the spatial autoregressive (SAR) model into a system of simultaneous equations. The resulting new model is useful in studying problems involving multiple networks where individuals are not only linked to members of the same network but also interact with members of the other …

Social Interactions and Network Formation -- EmpiricalModeling and Applications
… activities. By using the spatial autoregressive (SAR) model to study social interactions, one can utilize the detailed network information to construct a spatial weight matrix and generate the necessary nonlinearity to solve the reflection problem faced by the linear-in-means model. In my …

Spatial modeling of soil salinity using remote sensing, GIS, and field data
… systems (GIS), remote sensing, and spatial modelling techniques. Com and alfalfa crops were selected as indicators of soil salinity during 2001 and 2004 respectively. Five images were acquired from Aster, Ikonos, and Landsat to check the correlation between measured soil salinity and remote …

Synthetic Aperture Radar Simulation for Point and Extended Targets
… of these targets. Synthetic Aperture Radar (SAR) systems use the reflections to produce target images as well. SAR is an imaging radar system that produces high resolution images of a scene or target by using radar motion to synthesize the antenna aperture. A SAR model to handle extended …

Essays on Bank Spatial Competition, Stability and Resolution
… bank stability, using a spatial autoregressive model (SAR) with spatial spillover (contagion) constructed by weight matrices based on the inverse distance between a bank and its neighbouring banks. The results show a positive relationship between bank stability and market power, which supports …

Essays in Spatial Econometrics: Estimation, Specification Test and the Bootstrap
… in Li et al (2007), to a spatial Durbin (SD) model. This generalized APLE takes into account exogenous variables directly and can be used to detect spatial dependence originating from either a spatial autoregressive (SAR), spatial error (SE) or SD process. However, that measure is not …

The impact of environmental change on the Tualatin River cleanup — a case study of policy responses to climate change
… ecological assessment tool as a soft model in policy analysis can help governments and agencies to identify potential problems and policy options, as well to predict outcomes and potential drawbacks in the face of such environmental change. One such tool that may be adapted for use in …
