Abstract
In this paper, an informational asymmetry exists between investors and the issuer of an initial public offering about the value of the security. To avoid market failure, a solution is proposed in which the issuer makes a disclosure about firm value that is verified by an investment banker. The investment banker enters into a contingent contract with investors which imposes a penalty if the ex post observable cash flow indicates fraudulent disclosure. A bivariate signalling model is formulated and solved, and testable implications are derived from comparative statics analysis.
