Alfonso Flores-Lagunes and Kurt E. Schnier, "Estimation of Sample Selection Models with Spatial Dependence", Journal of Applied Econometrics, Vol. 27, No. 2, 2012, pp. 173-204. The file FS-Internet-Appendix-092409.pdf contains the additional simulation results not shown in the paper and the theoretical appendix with the proofs to the propositions presented in the paper. This PDF file should be readable using Acrobat Reader or any other program for reading PDF files. The data employed in the Empirical Application section of the paper are contained in the ascii file datafile-fls.csv. The first row of the file contains the names of the variables that correspond to the names used in the paper. In addition, the spatial weighting matrix employed in the same application is provided in the ASCII file W7.csv. Note that the order of the observations in the spatial weighting matrix corresponds to the order they have in the data file. Both data files are zipped in the file fls-data.zip. Since these are ASCII files in DOS format, Unix/Linux users should use "unzip -a". Authors Alfonso Flores-Lagunes Food and Resource Economics and Department of Economics University of Florida P.O.
