Indirect "announcement-effects" of electoral poll results:Two empirical 
approaches.
　
	The influences of electoral poll forecasts on election results are 
called as "announcement-effects" in Japan. In this paper I examined indirect
 way of "announcement-effect", that is, how financial contributions to
candidates or morale boosting of campaign workers are affected by 
publication of pre-election poll results. 
	In the first part of this paper, the relationship between amounts of 
financial contributions for candidates and their positions in  electoral 
poll results in 1990-1993 general elections is examined by pass analysis,
 but it would be difficult to find such indirect announce-effects as a 
whole. 
	In the Second section of this review, field research methods and 
questionnaire investigation are both used in studying  morale changes of 
canvassing voluntary workers according to opinion poll figures in 1996 
general election. In this inquiry, I could recognize that the enthusiasm for 
canvassing  and intention to pay contributions of campaign volunteers are
 significantly increased when their candidate's position in polls is 
marginal.
