or autocorrelated disturbances [17] or both [16] (hereafter called spatial SUR models).
In contrast, relatively small efforts have been put to develop the estimation methods of spatial SUR model. Because the spatial SUR models are good at analyzing the spatial dependence over time, it is important to investigate the estimation method for spatial SUR model. We present an iterative Maximum Likelihood (ML) estimation method to estimate the parameters of spatial SUR models.
