【摘要】We evaluate the usefulness of the spatial scan test in speci?cation testing for spatialeconometric models. The null hypothesis assumes equality of the mean values of a variable inall the locations of a geo-referenced data set. The alternative hypothesis relies on the existenceof one (or more) spatial cluster(s) where mean values differ from those of the rest of the sample.First, we conduct a Monte-Carlo simulation study to analyse the properties of this test whenapplied to regression residuals. Second, we illustrate this test with an empirical application onhousing prices in Madrid.
