COMPETITION AND DISCLOSURE*
研究了竞争压力如何导致企业不愿自愿披露产品质量信息，解释了为何只有高质量企业才选择披露，并指出强制披露法可能促进竞争、提高消费者剩余但降低企业利润。
There are many laws that require sellers to disclose private information about the quality of their products. But the theoretical justification for these laws is not obvious: economic theory predicts that a seller will voluntarily disclose such quality information, however unfavorable, as long as it is costless to do so. Here we show that competitive pressures between firms can undermine this full disclosure result, and explain why it may be the case that only high‐quality firms choose to disclose. In this setting, mandatory disclosure laws can promote competition and raise consumer surplus at the expense of firm profits, potentially increasing the efficiency of the market.
