In multiple-principal multiple-agent models of moral hazard, we provide sufficient conditions for the outcomes of pure-strategy equilibria in direct mechanisms to be preserved when principals can offer indirect communication schemes. The conditions include strong robustness in the direct...

We consider multiple-principal multiple-agent models of moral hazard: principals compete through mechanisms in the presence of agents who take unobservable actions. In this context, we provide a rationale for restricting principals to make use of simple mechanisms, which correspond to direct...

We study a model in which an issuer can manipulate information obtained by a credit rating agency (CRA). Better CRA screening reduces the likelihood of a high rating, but increases the value of a rated security. We find that improving the prior quality of assets can have no effect on the quality...
