“…However, it is found that their influence on the convergence results is great, and neglecting spatial effects clouds the causes, speed and nature of the convergence process (Islam, 2003;James & Campbell, 2013;2014). Previous literature shows that when spatial effects are incorporated into the convergence model, they tend to be significant and strongly influence the convergence speed (James & Campbell, 2013;Rey & Montouri, 1999). Most recently James and Campbell (2014) To account for spatial effects in tourism and economic growth, spatial Durbin models (SDM) have been used to capture the spatial interdependence in both dependent and explanatory variables (Yang & Fik, 2014).…”
