Abstract

This paper establishes that a targeted policy backfires because it reveals information about nontargeted units. In the world’s largest fishery, the regulator attempts to reduce the harvesting of juvenile fish by temporarily closing areas where the share of juvenile catch is high. By combining administrative microdata with biologically richer data from fishing firms, I isolate variation in closures that is due to the regulator’s lower-resolution data. I estimate substantial temporal and spatial spillovers from closures. Closures increase total juvenile catch by 48 percent because closure announcements implicitly signal that fishing before, just outside, and after closures is high productivity.

秘鲁鳀鱼渔业目标政策的信息和溢出效应
本文指出,有目标的策略之所以会适得其反,是因为它揭示了有关非目标单元的信息。在世界上最大的渔业中,监管机构试图通过暂时关闭幼鱼捕捞份额高的区域来减少幼鱼的捕捞。通过将管理微观数据与来自渔业公司的生物学上更丰富的数据相结合,我隔离了由于监管机构的低分辨率数据而导致的关闭变化。我估计关闭会产生大量的时间和空间溢出效应。关闭使幼鱼总捕鱼量增加了48%,因为关闭公告隐含地表明,在关闭前、关闭外和关闭后捕鱼都是高生产率的。(jel d83, o13, q21, q22, q28)
