This paper presents an empirical study of office rents and property fo
r individual buildings in down-taxes town Chicago in 1991. The results
show that 45 percent of property tax differentials are shifted forwar
d to tenants as higher gross rents. Application of the Hausman (1978)
test for specification error reveals that assessed value per square fo
ot (the base for the property tax) is exogenous with respect to gross
rent per square foot.
