1: | LeSage Synopsis Spatial Econometrics James LeSage This text provides an introduction to spatial econometrics as well as a set of MATLAB functions that implement a host of spatial econometric estimation methods. The intended audience is faculty and students involved in modeling spatial data sets using spatial econometric methods. The MATLAB functions described in this book have been used in my own research as well as teaching both undergraduate and graduate econometrics courses. Toolboxes are the name given by the MathWorks to related sets of MATLAB functions aimed at solving a particular class of problems. Toolboxes of functions useful in signal processing, optimization, statistics, finance and a host of other areas are available from the MathWorks as add-ons to the standard MATLAB software distribution. I use the term Econometrics Toolbox to refer to my collection of function libraries described in a manual entitled Applied Econometrics using MATLAB available at http:/www.econ.utoledo.edu. ... http://www.rri.wvu.edu/WebBook/Synopsis/LeSage.htm |

3: | Position Paper Luc Anselin Bruton School of Development Studies University of Texas at Dallas Position Statement Curriculum Vitae Address Position Statement GIS, Spatial Econometrics and Social Science Research The subset of the domain of spatial analysis that pertains to the statistical analysis of spatially referenced data has recently gained a growing acceptance as a methodology in the mainstream social sciences. I will focus my remarks on this specific issue, leaving the discussion of aspects of spatial analysis such as optimization and decision support systems to others. The recent dissemination of a spatial analytic perspective in the social sciences (outside of the discipline of geography) is often attributed to the rapid spread of GIS technology to the desktop and the availability of a vast array of geographically referenced socio-economic data. This has led to the use of GIS for data organization and visualization as well as increasingly in an inductive approach to exploring ... http://www.ncgia.ucsb.edu/... sa_workshop/papers/anselin.html |

6: | Spatial Statistics Software estimating very large spatial autoregressions (e.g., one example involves 500,000 observations). The spatial software uses sparse matrix methods to compute the matrix determinants employed in the maximum likelihood estimation of the spatial autoregressions. Specifically, the software can estimate simultaneous spatial autoregressions (SAR), conditional spatial autoregressions (CAR), mixed regressive spatially autoregressive (MRSA) estimates as well as other lattice models which are the mainstay of spatial econometrics. Version 1.1 adds maximum likelihood estimation of spatial autoregressions which uses only nearest neighbor spatial dependence. This special case results in a closed-form for the matrix determinant and also for the log-likelihood. Naturally, this special case lends itself to computational speed. For example, for 500,000 observations one can find the nearest neighbors and compute the maximum likelihood estimates in under 3.5 minutes on a Pentium III 500!

7: | Spatial Statistics Articles on individual houses in Baton Rouge. The combined transformations greatly improve the pattern of the residuals and reduces their magnitude. On a Pentium Pro 200 MHz PC it took under a minute to calculate the spatial log-determinant and under 10 seconds to calculate the estimated joint transformations. I plan to include this type of function in the Spatial Statistics Toolbox. Pace, Barry, Slawson, and Sirmans (forthcoming), "Simultaneous Spatial and Functional Form Transformations," Advances in Spatial Econometrics, Florax and Anselin, Editors. Using nearest neighbor spatial dependence leads to a closed form for the eigenvalues and hence the log-determinant of the spatial weight matrix. In turn, this simple result leads to a closed-form spatial maximum likelihood estimator. Hence, one can find the neighbors and compute the maximum likelihood estimates for 100,000 observations in under one minute (on a Pentium III 500 MHz machine)! Using OLS for data known a priori to exhibit ... http://www.spatial-statistics.com/manuscript_index.htm |

9: | EPA abstract Environment and Planning A 2000, volume 32 (8) August, pages 1481 - 1498 Spatial econometrics, economic geography, dynamics and equilibrium: a 'third way'? Bernard Fingleton Department of Land Economy, University of Cambridge, 19 Silver Street, Cambridge CB2 9EP, England; e-mail: bf100@cam.ac.uk Received 2 December 1999; in revised form 3 March 2000 Abstract. An important item of agreement between the 'new' economic geography and economic geography 'proper' is the role of increasing returns in regional economic development. This provides a focal point for the model proposed in this paper, which suggests a 'third way' somewhere between the analysis provided by these 'two' competing modes of explanation. The paper provides empirical evidence supporting the proposed model using data on manufacturing productivity growth across 178 NUTS2 regions of the European Union. The paper also includes expressions for an equilibrium implied by the fitted model and argues that this helps ... http://www.envplan.com/epa/abstracts/a32/a321481.html |
