Spatial Econometric AnalysisUsing GAUSS 3 Kuan-Pin LinPortland State University
Spatial Weights Matrix • Anselin (1988) [anselin.1] • Ertur and Kosh (2007) [ek.1] • China 30 Provinces [china.1, china.2] • Homework • U.S. 48 Lower States [us48_w.txt] • U.S. 3109 Counties [us3109_w.zip][us3109_wlist.txt]
Spatial Contiguity Weights MatrixChina, 30 Provinces and Cities: W1, W2, W3
Distance-Based Spatial WeightsErtur and Kosh (2007) • Geographical Location (x,y) • Longitude (x) • Latitude (y) • Great Circle Distance • d=gcd(x,y) • (x,y) is in degree decimal units • Distance-Based Spatial Weights Matrix • Using Kernel Weight Function
Distance-Based Spatial WeightsErtur and Kosh (2007) • Kernel Weight Function • Parzen Kernel • Bartlett Kernel (Tricubic Kernel) • Turkey-Hanning Kernel • Guassian or Exponenetial Kernel
Kernel Weights Spatial MatrixAn Example • Negative Exponential Distance • Negative Gaussian Distance
Spatial HAC Estimator • The Classical Model
Spatial HAC EstimatorGeneral Heteroscedasticity • Huber-White Estimator
Spatial HAC EstimatorGeneral Heteroscedasticity and Autocorrelation • First Law of Geography • Kelejian and Prucha (2007)
Time Series HAC EstimatorGeneral Heteroscedasticity and Autocorrelation • Newey-West Estimator
Crime EquationAnselin (1988) [anselin.2] • Basic Model(Crime Rate) = a + b (Family Income) + g (Housing Value) + e • Spatial HAC Estimator
GDP Output ProductionChina 2006 [china.3] • Cobb-Douglass Production Function ln(GDP) = a + b ln(L) + g ln(K) + e • Spatial HAC Estimator
Spatial ExogeneityLagged Explanatory Variables • Spatial Exogenous Model
