The local economic impact of State Parks is analyzed using a cross-sec
tion sample of 250 non-metropolitan counties from the eight-State inte
rmountain west. The analysis consists of the estimation of a disequili
brium, simultaneous econometric model of county economic development.
The number of State Parks per acre of county land area is found to hav
e a positive, statistically significant, but relatively small effect o
n both county population and employment densities. Specifically, 10 pe
rcent higher State Park densities are associated with 1.4 and 2.3 perc
ent higher long run population and employment densities, all else cons
tant. These findings are consistent with the hypothesis that household
s are attracted to high amenity regions and that regional amenities su
ch as State Parks can have both direct and indirect economic developme
nt implications.
