Abstract
The purpose of this article is to analyze if spatial dependence is a synchronic effect in the firstorder spatial autoregressive model, SAR(1). Spatial dependence can be not only contemporary but also timelagged in many socioeconomic phenomena. In this paper, we use three Moranbased spacetime autocorrelation statistics to evaluate the simultaneity of this spatial effect. A simulation study shed some light upon these issues, demonstrating the capacity of these tests to identify the structure (only instant, only timelagged or both instant and timelagged) of spatial dependence in most cases.
