Market-Based Corrective Actions
分析经济主体根据市场价格推断信息并采取纠正行动的情形，指出价格会因这种使用而调整并可能降低信息含量，探讨如何提高主体从市场价格中学习的能力。
Many economic agents take corrective actions based on information inferred from market prices of firms' securities. Examples include directors and activists intervening in the management of firms and bank supervisors taking actions to improve the health of financial institutions. We provide an equilibrium analysis of such situations in light of a key problem: if agents use market prices when deciding on corrective actions, prices adjust to reflect this use and potentially become less revealing. We show that market information and agents' information are complementary, and discuss measures that can increase agents' ability to learn from market prices. The Author 2009.
