People turn out to cast their votes simply because they want to ``cheer'' o
r ``boo'' their favored or unfavored candidates. This expressive voting beh
avior is in marked contrast to the instrumental voting behavior, i.e., peop
le vote because they perceive voting as a means of achieving a particular e
lection outcome. In this paper we report an econometric study on voting beh
avior that uses data from the 1988 American National Election Study. The re
sults reveal that the ``cheering'' and ``booing'' effects are statistically
significant, and that they exert substantial influence on both turnout and
voter choice. We also obtain evidence against the proposition that people
turn out to vote because they consider themselves to be potentially decisiv
e with regard to the election outcome.
