This paper explores the implications that spatial effects can hold for the application of measures of "&sgr;"-convergence. The bias of a common indicator of "&sgr;"-convergence is examined for a family of spatial process models including: [a] spatial lag, [b] spatial error, and [c] spatial moving...

This paper explores the implications that spatial effects can hold for the application of measures of sigma-convergence. The bias of a common indicator of convergence is examined for a family of spatial process models including: [a] spatial lag, [b] spatial error, and [c] spatial moving average....
