Appendix for “The Spatial Diffusion of Regional Housing Prices across U.S. States” June 2013 Abstract This appendix includes results referred to in Brady (2013) 1 but not included in the text for brevity. Included is an example of more detailed structural break results; the response of housing prices to the additional regressors in the sub-regions (corresponding to Figures3 and 5 in the main text); results from four sub-periods separated by break dates in 1988, 1999 and 2006; and results for the pre-1999 and post-1999 sub-period estimated with ordinary least squares instead of instrumental variables.

breaks # breaks Sequential Repartition 2 2 Notes: See Bai and Perron (1998, 2003) for descriptions of each of the tests reported in this table. The last four columns refer to procedures for selecting the number of breaks, the Sequential procedure and the Repartition procedure, followed by the Bayesian and Schwartz information criterions, respectively. For the Sequential and Repartition numbers, the number of breaks displayed is for the five percent significance level. The results displayed are for each regional price series modeled as an AR(1) in levels, with the break tests applied to the sample period 1987Q1 to 2011Q3. I imposed a maximum number of breaks equal to 3 and the minumum length of a segment equals 20 percent of the sample.
