We provide a real-options model of an industry in which agents time abandonment of their projects in an effort to protect their reputations. Agents delay abandonment attempting to signal quality. When a public common shock forces abandonment of a small fraction of projects irrespective of agents' quality, many agents abandon their projects strategically even if they are unaffected by the shock. Such “blending in with the crowd” effect creates an additional incentive to delay abandonment ahead of the shock, leading to accumulation of “living dead” projects, which further amplifies the shock. The potential for moderate public common shocks often improves agents' values.

Using an extensive data set on corporate bond defaults in the US from 1866 to 2010, we study the macroeconomic effects of bond market crises and contrast them with those resulting from banking crises. During the past 150 years, the US has experienced many severe corporate default crises in which 20–50% of all corporate bonds defaulted. Although the total par amount of corporate bonds has at times rivaled the amount of bank loans outstanding, we find that corporate default crises have far fewer real effects than do banking crises. These results provide empirical support for current theories that emphasize the unique role that banks and the credit and collateral channels play in amplifying macroeconomic shocks.
