Long-run exporting and importing of regional taxes is assessed theoret
ically and empirically using a six-region nonlinear general equilibriu
m model of the United States. The relationships between tax exporting
and three aggregate measures of regional change (value added, welfare
of all residents, and welfare of original residents only) are examined
empirically. The ability of states to adopt tax structures that succe
ssfully impose more of a burden on out-of-state residents does not nec
essarily promote regional economic growth or welfare, and evaluating t
ax policy based on its ability to promote economic growth may be misle
ading if regional welfare is the primary objective. (C) 1996 Academic
