Stock-Based Compensation and CEO (Dis)Incentives
研究了股票薪酬在解决股东与经理人代理问题时，反而诱导经理人隐瞒坏消息并选择次优投资政策，导致股价高估和崩盘，对理解金融危机有启示。
The use of stock-based compensation as a solution to agency problems between shareholders and managers has increased dramatically since the early 1990s. We show that in a dynamic rational expectations model with asymmetric information, stock-based compensation not only induces managers to exert costly effort, but also induces them to conceal bad news about future growth options and to choose suboptimal investment policies to support the pretense. This leads to a severe overvaluation and a subsequent crash in the stock price. Our model produces many predictions that are consistent with the empirical evidence and are relevant to understanding the current crisis.
