■テーマ： “Public announcements of violators and compliance behaviors under a
tradable permits scheme: Experimental analysis of market trading”（共著者: Kenta Tanaka and Teruyuki Tamura）
■言語：日本語
■要旨
If some market participants break market rules, market efficiency
deteriorates. Conducting laboratory experiments, we examine the
effects of public announcements and fines on violators’ behavior. Two
types of announcements are examined in our paper: announcements of
violators’ names and announcements of their IDs. Although several
types of remedial measures against market violations have been
implemented everywhere, the extent to which announcements suppress
violations is not clear. Our findings are fourfold. First, even when
the amount of fine is small, fines are the most useful punishment in
increasing market compliance. This finding may reflect a social norm
involved with paying a fine. Second, publicly announcing the names and
IDs of violators is helpful in suppressing violations. Market
compliance can be ensured by not only monetary interventions, such as
fines, but also by information disclosure, such as via public
announcements. Third, it is important for authorities to understand
the content that is publicly announced. Fourth, when implementing the
public announcement of violators’ names, market transaction volumes
and prices decrease and increase, respectively. This finding implies
that the announcement of names may have an influence on market
welfare.。
