This paper studies the extent to which the impact of tax policy on consumer
spending differs between temporary and permanent, as well as anticipated a
nd unanticipated tax changes. To discriminate between them, we use institut
ional information such as legal distinction between temporary and permanent
tax changes, as well as timing of policy announcement and implementation.
We find that the impact of temporary changes is significantly smaller than
the impact of permanent changes. We also find that more than 80 percent of
Japanese consumers, including those who distinguish between temporary and p
ermanent tax changes, respond to tax changes at the time of their implement
ation and not at the time of a policy announcement. We suggest an interpret
ation that these consumers follow a near-rational decision rule. (C) 2001 E
