The paper proposes a basic definition of intergenerational neutrality
of fiscal policy in the life cycle model. The requirement of intergene
rational neutrality imposes a restriction on the use of fiscal instrum
ents that eliminates any welfare effects from intergenerational redist
ribution and, thereby, isolates the price effects of fiscal policy. Th
is restriction endogenously determines a distribution of tax revenues
in the form of transfers to young and old agents which ensures interge
nerational neutrality. The share of tax revenues rebated to young and
old agents is interpreted as the intergenerational incidence of the ta
x system. If revenues are not refunded to agents according to the inte
rgenerational incidence of taxes, then redistribution in one or the ot
her direction is installed. Hence, the derivation of intergenerational
ly neutral tax effects provides a benchmark for evaluating the redistr
ibutive content of an arbitrary fiscal program.
