We propose to test for spatial correlation of the disturbances using estimated residuals of the within estimator. We derive asymptotic properties of the test and present simulation evidence to show that it also works well in finite samples.

This paper examines the Turkish wage curve using individual data from the Household Labor Force Survey including 26 NUTS-2 regions over the period 2005–2008. We find an unemployment elasticity of −0.099, with a higher elasticity for younger, less educated, less experienced and female workers.

This note shows that for a spatial regression with equal weights, the LM test is always equal to N / 2(N - 1), where N is the sample size. This means that this test statistics is a function of N and not a function of the spatial parameter [rho]. In fact, this test statistic tends to...
