Voluntary disclosure programmes offer tax evaders the opportunity to come clean with reduced penalties. This column uses data from the US and Germany to examine the merits of such programmes. They are found to increase tax evasion, but also to significantly lower administrative costs, leading to a net increase in tax revenues.

Theories of voluntary disclosure suggest that even when disclosure is voluntary, market forces can drive firms to completely reveal information about their quality. This column investigates these predictions in an experimental setting. Laboratory results suggest widespread failures of the theoretical predictions – senders do not fully disclose, and receivers are not fully sceptical about non-disclosure. This suggests a role for policymakers to help customers understand the sound of silence.
