This paper studies the performance of panel unit root tests when spatial effects are present that account for cross …-section correlation. Monte Carlo simulations show that there can be considerable size distortions in panel unit root tests when the true … specification exhibits spatial error correlation. These tests are applied to a panel data set on net real income from the 1000 …
