This paper addresses the general equilibrium incidence of various taxe
s in a Harberger-type two sector model in which one of the sectors is
subject to so-called ''fair rate of return'' regulation. It is demonst
rated that the presence of a significant regulated sector alters many
of the results of the Harberger model. For example, general sales taxe
s now alter the composition of output, the allocation of inputs to the
two sectors, and relative input prices.
