This paper proposes a model of signal distortion in a two-player game with imperfect public monitoring. We construct a tractable theoretical framework where each player has the opportunity to distort the true public signal and each player is uncertain about the distortion technologies available...

We explore the inter-temporal effects of the pool externalities caused by imperfect screening in competitive credit markets. We find that imperfect screening may, depending on the parameters of the model, generate excessive screening, inefficient duplication of screening or screening cycles....
